Hi Jiri,
I've pasted below the isometric class that I wrote
for one of my game books.
It is a handy class that allows for easy translation
between screen coords,
and iso coords. In addition, it handles tile-based
dept calculations as
well. You asked how do you handle multiple per tile
- check out the leeway
variable in this class. If leeway is set to 5, and
calculateDepth returns
1230, then you can place your item anywhere from
1230 to 1235. You just have
to keep track of which depth is being used.
You don't have to swap depths of every item every
frame. You just have to
swap depths on any items that has just changed
tiles.
There are two limitations with this technique:
1) It does the depth calculations based on the size
of the map. For most
uses this is fine. But if your map is like 5000 X
5000 tiles, then this
depth calculation can probably quickly get too high
for Flash to handle
without further modifications.
2) A sortable item needs to be no bigger than a
tile. If the base of this
item takes up multiple tiles (like a couch, or
bench, etc) then you need to
either slice it up into tile-sized pieces, or change
the depth approach. The
approach that you use if you are not slicing it up
does require resorting
lots of item depths frequently rather than using
just using unique depths
per tile.

Subject: [Flashcoders] Isometic game - zdepth
managing for multiple
movablecharacters
He guys (and maybe girls),
I have a question that is related to z-depth
managing in an isometric
game, that needs to be made in AS2.
In the game I basically use one abstract layer
that holds all the tiles
and their information wheter or not a movable
object is allowed to 'walk'
over the tile. Then there is another layer that
holds all the objects, so
that includes a player, a computer controlled
player and enviormental
objects that players cannot walk through being the
visualization of the
first layer.
Every object gets a z-depth assigned. For the
players the zdpeth need to
be set based on the tile they are at. This way the
players can walk
'around' the enviorment objects. For the z-depth
calculation I use the
tile grid x and y plus the width of the row, this
generates an unique
z-depth number and makes sure that the higher the
y, the bigger the
z-depth , thus objects appear infront of objects
with a lower y index.
Here is the problem I am trying to figure out. If
two movable objects, or
even three of them are at the same time on the
same tile, then the above
described z-depth managing will fail. How do I
deal with that?
Then another question I have is this. Does every
movable object needs to
check/swap z-depth on every frame. Wouldn't that
be to CPU intensive?
I really hope someone can clear this up for me.
thank you in advance,
Jiri

Re: [Flashcoders] Isometic game - zdepth managing for multiple movablecharacters
A quick clarification on using _y value to control z depth: You don't need to make sure no two objects share the same _y value. Every object should have some sort of unique ID between 0 and whatever you're multiplying the Y value by. In the example, an ID between 0 and 99. EX: var limit:Number = 100; this.swapdepths(this._y * limit + this.id); This means two objects can have the same _y value without overwriting each other, depth-wise. --- Jiri Heitlager [EMAIL PROTECTED] wrote: First off, thanks that you people took the time to help me out and thank you Jobe for sending me your class. I appreciate that, but would really like to program the game myself from scratch to get a full understanding on how games like this are made. I am reading all the replies and trying to see if I am understand them correctly. Basically I have two options. Give every movable object the depth of the screen _y value and make sure that objects can never be on the same _y position. Second option. If the movable objects only move one tile at a time, meaning that their screen _y position could sometimes be the same, I need to assign for every tile a range of n numbers of depth that can be taken. Then check for an available depth within each tiles indivudual range of depth , when a movable objects is on a tile. @Danny, could please explain your comment on subsorting a bit more. I am not quit sure if I understand it. However, you can optimise quite a bit by sub-sorting - if you know that object 1 is in the rear 16 tiles and object 2 is in the front 16 tiles, no need to check the z-order.

If this is possible in your game then you'll need to either store sub-tile positions and z-sort further on those (you could, for example, assign ten z-slots per tile to ensure that you have more space) or randomly choose one to be in front of the other (if there's only one position per tile, then it doesn't matter which one gets drawn in front). Then another question I have is this. Does every movable object needs to check/swap z-depth on every frame. Wouldn't that be to CPU intensive? Depends how you do it. If there's only a few movable objects, this shouldn't be particularly hard on the machine - Flash isn't the fastest thing in the world, but it's fast enough for that.

Re: [Flashcoders] FMS 2 multiplayer game
You're running into the same latency problems I did when I tried to do a real-time game in Flash. The movement's fine, you're correcting for latency burps fine, but events like someone else stealing the ball is unpredictable. I can steal the ball from someone else, bu running halfway down the field away from everyone, and have the ball disappear and reappear next to someone else's icon. The ball-theft event is incredibly time-sensitive, so it's very important that people know when and where it happens. If you manage to find a workaround to this, post it on the list, because I really don't think it can be worked around without using UDP packets, and Flash doesn't support that, and none of the 3rd party projector apps allow you enough control over the packet to make UDP hole punching work, which is what you need to get past firewalls. --- Norman Cousineau [EMAIL PROTECTED] wrote: I recently made a multi-player soccer game prototype based on FMS 2.

Re: [Flashcoders] Synchronized game timing
Are you trying to do a real-time game? Because I've been playing around with real-time games with Flash and Java myself in the last month or so, and so far, my conclusion is that it's not workable.

There are 3rd party projectors that have UDP functionality, but then you have to worry about firewalls.

Re: [Flashcoders] Synchronized game timing
So I'm assuming you want synchronization because if it's off, then more or less of the users scribbles could be erased when the screen clears, so different people would wind up seeing different things. Each message from the client to the server could have a unique ID(something incrementing so you know which message comes before which), and when the server fires the clear screen event, it could also tell the client which two IDs the clear event occurred between. This would require the client to keep a buffer of positions so that it could reconstruct what the user had drawn after the screen clear, but that shouldn't be too memory-intensive. --- Mick G [EMAIL PROTECTED] wrote: It doesn't have to be constant perfect timing. Basically it more of a casual multi-user scribble-pad. I only need synchronization to automatically clear the canvas every 5 minutes. That's the only thing that needs to be in sync and it can have a second inaccuracy but not much more. It's working OK now when I get the server time and just make it do the canvas clear on exactly every 3rd minute, there's just about a 2-3 second difference and I'm hoping to get that a little more accurate somehow.

Re: [Flashcoders] Backend compiled Java or scripted PHP?
You have to worry much less about Memory leaks, and syntactically, the language is simpler than C++, so saying that it's become more complicated than C++ is total bull. Still, they're just different beasts. I'd rather write most web apps in PHP, but you could never write your own server in PHP either. PHP is really just about doing things with HTML. The filesystem, image manipulation, and other functions are secondary to that. Java is meant for applications, which means that you can make it mangle HTML, but it takes longer. You could never write a server in PHP, but if you wanted to throw a simple XML file at a Flash application, Java would be total overkill. --- Weldon MacDonald [EMAIL PROTECTED] wrote: I've been using ActionScript for a while now, but my next project will require a lot more server side work.

Re: [Flashcoders] Standalone projectors and UDP
That's probably a very good thing for me to check, or at the very least a good thing to keep in mind when other people come to me asking why my game doesn't work later on. I've actually managed to get UDP traffic through NAT now, with no port forwarding, tricks, or hacks on the client side. The downside, is that I've only managed to do this through Java. It seems like MDM Zinc might not be formatting their packets in the same way. I think it doesn't fill in the sending IP, or sending port fields. There also seems to be problems keeping a TCP/IP connection open, and sending UDP packets at the same time. I'll do some more research and try SWF Studio next. Anyway, the final thing I used was called UDP Hole Punching, and there's a really good wikipedia article about it. --- Jim Ault [EMAIL PROTECTED] wrote: One aspect of UDP to check is the max packet size handled by your equipment. Different computers and routers have varying limits, and the failure is silent. This means that you should test the firewall/equipment with very small packets to see if there is a connection, then increase the size to find the limit. Vonage uses UDP and many stock data feeds as well, largely due to the speed. I don't know the specifics, but there should be something out there that gives recommended packet sizes.

RE: [Flashcoders] Standalone projectors and UDP
Thanks for the links. I'm pretty sure it's not a crossdomain.xml, or security sandbox problem tho. One thing to clarify: I'm using MDM Studio right now. I might be using SWF Studio later, but in both cases, just to use their UDP functionality. This is a client/server application. The server is receiving packets fine, I have port forwarding set up appropriately on the server end. The client's firewall is stopping UDP traffic. Because it's a game, I want as little setup on the client side as possible. The client shouldn't care about port forwarding, proxies, and whatnot. The server can do a ton of configuration for all I care, but the client shouldn't have to do anything beyond knowing where the server is. --- Palmer, Jim [EMAIL PROTECTED] wrote: I usually solve this by setting up a proxy on a host accepting data from flash apps through a known port.

Re: [Flashcoders] Mouse Velocity?
Well yeah. If you're doing a verlet integration-style
thing where all you store about a particle is it's
last position, and it's current position, and you're
not using a constant time step, you have to do that.
Storing the last 5 updates is a seperate thing.
This is just to overcome the difference in time
between the interval firing and the mouse moving. If
the mouse is updated every 10 milliseconds, and your
interval fires every 7, you're going to get intervals
where the mouse position hasn't changed.
The solutions, really, are to slow down your interval,
or just average things.

Re: [Flashcoders] Grid / Math - getting neighbouring positions
The easy way to do this is like so.
So you have a square at x,y, and you want to get all
the squares n squares away.
Get squares
x+n, y
x-n, y
x+n, y+n
x-n, y+n
x+n, y-n
x-n, y-n
x, y+n
x, y-n
I suspect you want to do this for your version of that
whale-ey thing though, so what you actually want to do
is a bit different.
First off, to find out which grid square a point fits
into (this being the center of where your user is
looking):
You need the height and width of your grid squares.
Take your point (x, y)
Your point fits into grid square
[Math.floor(x/squareWidth),
Math.floor(y/squareHeight)]
Apply this by figuring out where on the big picture
your person is looking.
After that, move left and up by half the screen width,
and height, then right and down by the same amount,
and you have the ranges of squares to get in order to
display that part of the image.

Re: [Flashcoders] Easy game in flash
--- gareth gwyther [EMAIL PROTECTED] wrote: btw Apps are easy to create. Games are evil in comparison. They're both hard, but in different ways. Apps have a low, almost linear learning curve, but the time axis is huge. Games have a steep curve, but once you have the math down, you can kick out almost anything relatively quickly. I've done both, and what it comes down to is that I'd rather do applications/websites for a living, and occasional games for a hobby. That way, I'm constantly challenged (in a fun, moderately challenging way) by all the new things one has to learn in an application/business context, and I don't get burned out by having to do dead-simple games all the time. Plus, when I do want to do a hyper-complex game that would cost a team of professionals thousands of thousands of dollars to do and a lot of time, I can do it on my own time, and when the game fails to materialize for whatever reason, there's no client to tell that you spent their money on beer and comics. Anyway, the most dead-simple game I can think of to learn some game programming basics if probably Asteroids. There's practically no physics beyond simple inertia to worry about, since you dont have to worry about rock/rock collisions, just ship/rock, and bullet/rock collisions, and there's no AI. The next most simple might be Pang, or Buster Bros: http://en.wikipedia.org/wiki/Buster_Bros It has similar mechanics to Asteroids, but you add gravity, and bouncing. Plus, if you want to get more complicated, you add swept-circle collisions, (google it) and some of what it takes to make a platform game. Lastly, since you (the original poster) is 15, you definitely want to make sure you've got a lot of math experience, since modern and professional game programming requires a lot. Trig's important, calculus is good for physics and whatnot, and check linear algebra for 3D stuff.

Re: [Flashcoders] AS3 Mouse suggestions?
That's a hard problem since you have no direct control
over the mouse, other than hiding and showing it.
I probably wouldn't hide the mouse in this case, since
mouse movement and player movement aren't 1 to 1. That
way people can see if they're moving the mouse out of
the game area. It's uglier, but it might be necessary.
That said, if you want to tie the player directly to
the mouse, I would look into line-circle intersection
algorithms, or swept-circle to circle collision
detection. Every update, you draw a line from the
previous player position to the new position. If it
intersects a mushroom, store the previous position,
find the first point of intersection, and stick the
player there.
Next update, go from the stored previous position to
the current mouse position, check for intersection,
etc. etc. until there's no intersection, then stick
the player on the cursor again.
--- Martin Scott Goldberg [EMAIL PROTECTED] wrote:
Hey all, back again.
I'm doing a remake of centipede, and am looking for
suggestion on the
mouse tracking routine (in as3).
The enivronment: The player is of course at the
bottom of the screen, and
can only move up a specific distance. He may be
blocked by mushrooms in
this area as well.
Speficially, I have two ways of player motion with
the mouse I've tried
and neither one is 100% accurate:
1) Set the player graphic equal to the mouse
reading:
thePlayer.x = this.mouseX;
thePlayer.y = this.mouseY;
This is the same as thePlayer.startDrag(), just
chose to go this route.
Player tracks the mouse motion perfectly this way
of course.
Then the code checks for mushroom collision,
which stops the player
motion.
The issue I'm having is, whenever the player
comes in contact with
a mushroom in the lower player movement area,
it's supposed to stop
dead, forcing the player to move around it. With
this method though,
it stops for a second, but then skips over the
mushroom once the mouse
moves past it. Likewise, it creates a sticking
at the upper, lower
right, and left boundries since it sits there
until the mouse enters
back in to the player zone.
2) Record previous mouse motion in x and y, and
compare it to current. If
its moving right, move the player right 1 place.
Mouse moving left,
moving player left one space, etc.:
if (previousMouseX this.mouseX)
{
thePlayer.x += playerSpeed;
}
else
{
thePlayer.x -= playerSpeed;
}
And similar for y direction. Now, this code
works perfect with the
mushroom obstruction dectection. But I'm having
the opposite issue
from the first code: The mouse tracking makes it
harder to move in a
straight line, and the mouse moves out of the
stage very quickly,
being out of proportion to the rate of the player
motion. Upping the
playerSpeed of course doesn't help, that just
makes the player graphic
jump around to quick.
If anyone on this list that's played around with
these types of issues
before has an suggestions, I'd greatly appreciate
it.

So if the Garbage collector delete classes with no references to them immediately, but waits to do the more expensive check to see if the class has no references from the root, then with your classes that you know will have circular references, would it be a good idea to write a dispose method that does a for in loop on the instance, and deletes everything it can find? In other words, when you don't need an object, you just delete it, or make all references to it null, but if your object contains an object that has a reference to the original object, then there's still a reference. So you just include a method in the contained classes that delete all their references, and a method in the containing class that does the same thing, so if you do everything right, when you call that method, it takes care of eliminating all it's references, and gets cleaned up more quickly. Don't pick lemons. See all the new 2007 cars at Yahoo!

Re: [Flashcoders] drawing with mouse / pen
The drawing part's easy. For closing off the circle, just do what Flash does for the endFill() method, just connect the last point in the polygon you're creating with the first. The for selecting the right answer, it's a point in polygon problem. Now that I think about it, create an empty movie clip, do a beginFill(0,0) in the new clip, follow the mouse to draw, on release, endFill(), then do a hitTest with the center point of each answer and the movieclip you just created. If there's two center points that hit your clip, kill it and make the user draw again. --- nik crosina [EMAIL PROTECTED] wrote: Hi, I am working on a project that would possibly require the user to select an answer from a quiz by circling it with the mouse.

Re: [Flashcoders] [FlashGameCoders] Persistent Game AI for Off-screen baddies
Separate your display code from your game logic. One thing that I see frequently is people inheriting directly from movie clips for their game objects. This is bad because it encourages overuse of inheritance, and makes display/game logic separation harder. Usually, I'll have my game object as separate items, with their own x and y properties, then a viewport object for determining where you're looking. To determine what gets displayed, I'll check to see if the game object is within half a screen distance from the viewport, and if it is, and not already displayed, I'll attach a new movieclip, and position it relative to the screen center by the distance from the viewport to the game object. --- James Marsden [EMAIL PROTECTED] wrote: Hello all, When building a game where collision detection for enemies is important (such as a scrolling tile game), how do you create persistent AI for an enemy when it's off-screen? For example, walking away from the enemy causes it to be removed from the game area, but the enemy needs to keep wandering around the world in virtual terms, so the player can't easily tell where the enemy is going to be when returning to the same area. How do you maintain that interaction for the enemy, or is it not done like that because it's too processor intensive? Any tips or pointers to resources would be much appreciated. Thanks!

RE: [Flashcoders] Wave effect
One thing you're doing right is that you're not using
an easing function to move the center of magnification
to the mouse pointer. I looked at that mandchou site,
and it's really not good from a usability standpoint.
OSX's magnification feature is directly tied to the
pointer, which means that you don't have to chase
icons down, which is something that you don't even
have to know anything about usability to know to
avoid.
The thing causing that awkward pop on your version is
that you're using the distance from the icon to the
pointer to know when to magnify or not. This distance
shrinks or grows depending on how big the icon is,
which leads to weird feedback.
Also, if you have a mac handy, turn on magnification
on the dock. Notice that when you mouse over the dock,
the icons move away from the magnified icons in both
directions, whereas in your example, they only move
away form the magnified ones downwards.
Really, if you want that effect, follow OSX's example,
and not mandchou's.

Re: [Flashcoders] Curves question for math gurus
A bezier curve would be one way to go about it. Flash's curveTo method uses a quadtratic curve though, so using a cubic curve won't give you an accurate curve. If you know that the two endpoints of the curve are always going to have an equal x or y value, the you can just use the quadratic formula, and get the right Y value. If the endpoints are arbitrary, it's a bit more complicated. Bezier curves take a number from 0 to 1 and give you a point along the curve. Plugging 0 into the formula gives you the first endpoint, 1 gets you the last, and anything else gives you something in between. This means you're going to have to figure out where along the curve your MC is closest to, which involves some vector math. If you want, I can draw out the way I'd approach it. --- leolea [EMAIL PROTECTED] wrote: Hi, thanks for your reply! My curve isn't exactly a circle.

Re: [Flashcoders] Curves question for math gurus
Actually, you're right. if your endpoints will never
move, you can still use a quadratic bezier.
The percentage would be
(mc._x - firstpoint.x)/(lastpoint.x - firstpoint.x)
Since you're using curveTo, you already have all the
points you need for the formula Here's a function for
you:
import flash.geom.Point;
function getPoint(first:Point, last:Point,
control:Point, ratio:Number):Point {
var pReturn:Point = new Point();
var b:Number = 1-ratio;
pReturn.x = (b*b*first.x) + (2*ratio*b*control.x) +
(ratio*ratio*last.x);
pReturn.y = (b*b*first.y) + (2*ratio*b*control.y) +
(ratio*ratio*last.y);
return pReturn;
}
first if the first point in your curve, last is the
last, control is the point specified by the first two
arguments in the curveTo method.
This will give you the closest point on the line to
your MC's position. If you only want to snap if the MC
is within a certain distance, just check the
difference of the ys of your mc's position, and the
returned point.

MC._x / (lastpoint.x - firstpoint.x)
Just curious, but I don't think I need this since my
two endpoints will not

If you want, I can draw out the way I'd approach
it.
Of course I'd be more than happy to see that.

Re: [Flashcoders] basic flash games development issues
I'd look into using SharedObject for high scores. Why do you need to display PDFs? Instructions? Disclaimers? If they're instructions for the games, you can try importing them into the library. Alternately, if that gives you troubles, import them into Illustrator, then export them as .swfs. Then you can integrate them into the games themselves which is much better usability-wise. Really though, having the games link to PDFs isn't such a hot idea. --- nik crosina [EMAIL PROTECTED] wrote: Hi, I am putting together a quote for a client who needs to have a number of games developed for a DVD.

Re: [Flashcoders] trig? calculus? put me out my misery
Here's the vector math solution: Get the vector from the mouse to the MC: var vToMouse:flash.geom.Point = new flash.geom.Point(); vToMouse.x = MC._parent._xmouse - MC._x; vToMouse.y = MC._parent._ymouse - MC._y; Normalize the vector. This means you set the length of the vector to 1. var vectorLength:Number = Math.sqrt(Math.pow(vToMouse.x, 2), Math.pow(vToMouse.y, 2)); vToMouse.x /= vectorLength; vToMouse.y /= vectorLength; Now, since multiplying a vector by a number means that you're multiplying the length of that vector by that number, you can multiply our vector by enough distance to send it off-screen. Let's say 400 pixels. vToMouse.x *= 400; vToMouse.y *= 400; Lastly, add the vector back to the position of the MC to the the offscreen position var vOffScreen:flash.geom.Point = new flash.geom.Point(); vOffScreen.x = MC._x + vToMouse.x; vOffScreen.y = MC._y + vToMouse.y; Now you can use a tween class, or whatever to send the MC off screen. --- Kurt Dommermuth [EMAIL PROTECTED] wrote: Hi all, I have what I initially thought was simple problem, but I've been racking my brains, searching the web and I just don't get it.

Make sure you escape your data, since SWFObject
doesn't do this automatically:
function getInnerCode(id) {
var element = document.getElementById(id);
return escape(element.innerHTML.toString());

Re: [Flashcoders] determining which object is displayed at agivenpoint
The only case in which depth would be identical for
two movieclips is if they both were contained in
different parent movieclips.
In that case, check the parent's depth, and use that
to resolve the conflict. If both of those are the
same, continue going up until the conflict is
resolved.
--- Vishal Kapur [EMAIL PROTECTED] wrote:
It looks like you spent some time on this response,
I really
appreciate that. As I mentioned in my first mail,
depth, _visible and
_alpha are the properties I'm checking right now to
resolve conflicts.
So my code looks very similar to your code below.
This works
sometimes, but I've run into cases where there are 2
movieclips for
which hitTest() is true, _visible is true, _alpha is
100, and the
depths are identical. One of the movieclips is
obscured behind the
other; there must be some way to distinguish them.
Are there any
other properties on movieclips (maybe hidden ones)
that might be of
use? The Flash runtime must be doing this
internally for onRollOver
event firing; anyone know how this works?
Thanks,
Vishal
On 2/7/07, Karina Steffens [EMAIL PROTECTED]
wrote:
Ok, I see your problem, so lets think what else
you can do with the hitTest
approach...
First of all, you can set the shape flag to true,
so that the hit test will
only return true if there's something there (as
opposed to the entire
bounding rect).
Then you can test for _alpha (you might want to
test for _visible also),
thus eliminating invisible buttons, such as your
big rectangle that obscures
the rest.
Finally, checking for different depths - I
recently discovered that if you
loop through a clip, it starts at the highest
depth, even on the same layer:
for (var i in _root) {
trace(i + +_root[i].getDepth());
}
$version
clip3 -16379
clip2 -16381
clip1 -16383
So now you know which one has the highest depth:
clip3, which also comes
first in the loop.
At this point, you can break the loop. If you need
to go deeper, you can
then recurse within that clip, and see if it has
any child mcs, which one of
those scores the highest hitTest and if that one
has any children - etc.
Here's some quickdirty code:
for (var i in _root) {
trace(i + +_root[i].getDepth());
}
_root.onEnterFrame = function() {
for (var i in this) {
var clip = this[i];
if (!(clip instanceof MovieClip))
{
continue;
}
if (clip._alpha == 0 ||
clip._visible == 0) {
continue;
}
if (clip.hitTest(_root._xmouse,
_root._ymouse, true)) {
trace(clip);
break;
}
}
};
On the timeline, I placed three circular clips
overlapping eachother, so
that clip1 is at the lowest depth and clip3 at the
highest. I made clip3
invisible by setting it's alpha to 0.
After moving my mouse over the clips, starting
from the third, the trace
result was:
$version
clip3 -16379
clip2 -16381
clip1 -16383
_level0.clip2
_level0.clip2
_level0.clip2
_level0.clip2
_level0.clip2
_level0.clip2
_level0.clip2
_level0.clip1
_level0.clip1
_level0.clip1
Each time the trace picked out the highest visible
part of a clip, thus
resolving any conflicts.
Hope this helps to point you in the right
direction.

Subject: Re: [Flashcoders] determining which
object is
displayed at agivenpoint
To respond to the recent activity on this
thread:
Erik, the core functionality that I need really
does need to
be comprehensive and fairly generic: so, given
any 3rd party
swf which I don't have a priori knowledge of,
determine which
object is currently underneath the mouse. It
needs to work
for any movieclip or TextField object. It's
proprietary so I
can't really disclose why I need it.
You mention that implementing this would be
process
intensive: this is ok to start. The way I would
like to
tackle this problem is to get it working
functionally, and
worry about performance later.
Karina, Jason, the approaches you are suggesting
of looping
through all the movieclips and calling hitTest()
on each one
is exactly what my first approach was (see my
first email in
this thread). The problem is that very often
multiple
movieclips will return hitTest()==true for a
given mouse
position (clips at different depths, clips
obscuring others,
etc). That's what I meant by 2 conflicting
objects in my
first mail. I'm trying to find an algorithm to
resolve conflicts.
There is another approach which Erik mentioned,
which is to
define/override the onRollOver
Re: [Flashcoders] text length difference
When you enable html in a textfield, Flash adds a bunch of formatting in HTML. If you trace the htmlText property of the textbox in question, you'll get something like: TEXTFORMAT LEADING=2P ALIGN=CENTERFONT FACE=Times New Roman SIZE=8 COLOR=#00 LETTERSPACING=0 KERNING=0BThis is a test/B/FONT/P/TEXTFORMAT If you trace the text property of that same textfield, it won't count the HTML tags, so you'll get a number less than what you'd expect from a string with HTML formatting. Lastly, when you enclose a string in the CDATA tag, it converts things to HTML entities, which can confuse things even more. --- PR Durand [EMAIL PROTECTED] wrote: Hi list!
