Re: [Flashcoders] AS2 OOP Class Structure for simple pong type game
Hi,
you should take into account the fact that the balls don't occupy one
tile only, since it is possible that it can occupy 2, 3 or even 4
tiles.
On 12/14/06, Paul Steven [EMAIL PROTECTED] wrote:
Dan, I was thinking using the tile solution would reduce the amount of
checks as instead of looping through all the brick objects and checking for
a collision using hitTest, I would simply call a function passing in the
balls current position and if this was a tile (brick) that hadn't been
destroyed, it would destroy the brick
So the bricks would be represented by a multidimensional array like so
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
1,1,1,1,1,1,1,1,1,1,1,1,1,1
1,1,1,1,1,1,1,1,1,1,1,1,1,1
1,1,1,1,1,1,1,1,1,1,1,1,1,1
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
0,0,0,0,0,0,0,0,0,0,0,0,0,0
And the method would use the balls x and y position to calculate the tile
row and column
var numTileColumn:Number = passedX / numTileWidth;
var numTileRow:Number = passedY / numTileHeight;
if (map[numTileColumn][numTileRow] == 1) {
// Destroy Brick
}
Hopefully this makes sense. I have just written this code off the top of my
head so haven't implemented it in the game yet

From a computational standpoint, you end up running the same amount of
processses. Are you either haveing the ball constantly checking Where am
I? Am I over a brick? or you have the ball checking Am i hitting
something? every onEnterFrame.
Pete's suggested having checks when it reaches a vertical threshold, but
again, you just change the the ball from asking Am I hitting something? to
am I over the threshold? every onEnterFrame, and then add additional
computation to figure out what its hitting.
I like Mike's solution of breaking out of the loop after a collision is
detected becuase then you don't perform unnessary computations (assuming the
ball can only be hitting one thing at a time).

Rather than testing every brick for a collision all the time, I was thinking
of using a tile based approach to display the bricks. Therefore rather than
each brick checking for a collision with the ball, it is a case of checking
what tile (brick) the ball currently occupies if any and if that brick has
not yet been destroyed then destroy it...
Hence a multidimensional array would be used to represent the bricks on the
screen.
Haven't implemented this yet but it sounds ok in my head:)

I don't program games (so add that factor as a consideration), it was
just my first thought that if I were doing this, I wouldn't want to test
every object for a collision all the time. If there is a latency issue
such as you describe, a homebrewed Event class might eliminate it.

Have you actually implemented an event system like this in games? It
seems
like a good idea, but for some reason I always thought this approach
would
introduce unnecessary latency, but now I'm not sure why!

Another possible strategy is for the ball to fire off an event
every
time it crosses certain vertical location thresholds. The target
objects could then listen for the event which matches their
vertical
location to test for a collision.
For example, when the ball descends to the row containing the
paddle,
it
fires that event, and the paddle, receiving it, tests for
collision.
When the ball ascends to the first row of bricks, those bricks each
test
for collsion. This might be a performance improvement over testing
every object in the system all the time.

We've got a bunch of animations created in earlier versions of Flash, and when we bring them into Flash 8 all the shape tweens are messed up.

[Flashcoders] ScrollPane malfunction in IE but not Firefox
Hello Please look at the following flash app in Firefox and Internet Explorer: http://dennislandi.com/tiledesigner/tile_designer05_x100.html On my two machines when the cache is cleared, IE will not load the scrollPanes correctly. Once I allow IE to finish loading the thumbnails (although they are not loading inside the left scrollPane as intended). I then can refresh the page and the app works as expected, the images loading *inside* the scrollPanes. Firefox works correctly all the time. I load each scrollPane.contentPath property like this: _root.leftScrollpane.contentPath = 'mc_empty.swf'; - with an empty SWF file. I then use this loaded movieclip as a canvas to draw vector images as well as host new movielips with which I load the actual images. Could it be that the scrollPane is not properly loading content via the contentPath property before I start populating each ScrollPane? I don't see how that can be since I begin populating these scrollPanes in their respective complete event handler, so this by definition should guarantee that the contentpath has been correctly loaded before I perform any further operations on each scroll pane. Any ideas? Because is works flawlessly in Firefox every time, I am inclined to think this is a problem with IE. The same problem occurss in IE6 and IE7. What can I do in my code to get around this problem in IE? Is this the best forum to ask this sort of question, or is there a better forum? Thanks for your time in advance. -d P.S. On a side note, I've never been able to load a scrollPane.content path from a movieClip in the library but only load it as as external file on my webserver? What is the secret to loading the scrollPane.contentPath from the library?

Re: [Flashcoders] SWF Decompiler
andy, are you decompiling your own SWFs? also, what are you seeking from decompiling the SWFs? i ask for 2 reasons: 1) if you are decompiling other people's SWFs, they usually do not like it, so stop. 2) not all SWFs come from FLAs anymore. if you do not know the provenance of the SWF, after decompiling you may end up with gibberish. decompilers originally tartgeted FLA authored SWFs but today they may be from MXML, SWiSH Max, etc. that all having been said, i concur with Alias. Buraks.com/ASV is the gold standard for SWF decompilers. it costs $$ but it is worth it. i have also tried Sothink but found it no where in league with Buraks.com/ASV.

[Flashcoders] Area of a triangle using perimiter values only
I'm trying to figure the area of a triangle in Actionscript using the
perimeter values only, not the traditional simple formula:
area = (height/2)*base
because figuring the height is tricky given the triangle will be drawn
in odd ways (i.e. a not horizontally alinged base), so I am exploring
other triangle area forumulas that only take in the perimiter values
(a,b,c), like Heron's formula or this one, which I like:
given a,b,c are the length of the sides of the triangle, then the
formula is:
squareRoot of: (a+b+c)(b+c-a)(c+a-b)(a+b-c)
___
4
So in trying to translate that to actionscript, I wrote:
public static function areaOfTriangle(a:Number, b:Number,
c:Number):Number{
return (Math.sqrt((a+b+c)*(b+c-a)*(c+a-b)*(a+b-c)))/4;
}
But the problem is (a+b+c)*(b+c-a)*(c+a-b)*(a+b-c) results in a negative
number, and this the square root cannot be taken. Or perhaps I am
interpreting the forumula incorrectly:

RE: Re: [Flashcoders] Area of a triangle using perimiter values only
Without looking up the source of that formula (i.e., just based on what
you wrote), I determine this: that in order for the result of
multiplication to be negative, one of the terms containing subtraction
must be negative. In order for that to occur, one side of your triangle
is longer than the sum of the other two. That is impossible. Check
your parameters.

Oh, but I just thought of something from my old rusty brain. I
looked
at the formula on the mathworld page; would that not indicate a
distributive method of multiplication? Again, rusty, but a
thought.
Let us know what you figure out!!

Re: [Flashcoders] Area of a triangle using perimiter values only
Hi Jason
If the number is coming out negative the most likely reason is that
the numbers you are supplying do not make a triangle. (e.g. two sides
are length 1 each and the third is 2 or more). I've tested your code
and it does produce positive numbers for all valid triangles I've
tried.

Re: [Flashcoders] Area of a triangle using perimiter values only
Negative result of ((a+b+c)*(b+c-a)*(c+a-b)*(a+b-c)) is not possible if a,b,
and c are lengths of a triangle's sides. The first term will always be
obviously positive, and so will the other three terms -- they are simply
the sum of the lengths of two sides less the third side, and you can't have
a triangle where that isn't true. It's most likely that your input numbers
to the formula are incorrect. Trace that to find your problem.

Re: [Flashcoders] Area of a triangle using perimiter values only
I'd stick to using Heron's rule -- there is no reason why it shouldn't work given correct inputs, and it is less expensive computationally. On 12/14/06, Danny Kodicek [EMAIL PROTECTED] wrote: I'm trying to figure the area of a triangle in Actionscript using the perimeter values only, not the traditional simple formula: area = (height/2)*base Try: area = 1/2 * a * b * sin(C), where C is the angle between the two sides a and b. You can calculate C using the cosine rule: c^2 = a^2 + b^2 - 2ab * cos(C). A bit of manipulation will give you sin(C) in terms of cos(C) so you can avoid using any trig (sorry I have to rush so I don't have time to do it right now) HTH Danny ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

Re: Re: [Flashcoders] Area of a triangle using perimiter values only
Jason,
It must be true that your inputs are incorrect, BUT to answer your
question about distributive methods - I was just thinking about
condensing that formula. If you did that(and they do it in the next
step on the MathWorld link) then you have to multiply every term in
parens by every other term in parens and you get all of that whacky
a^4, b^4 business. As it is, you're supplying your function with the
values of a, b, and c, so you can add them in the parens and multiply
out the whole numbers. False alarm there!
Cheers

Re: [Flashcoders] Area of a triangle using perimiter values only
Heron's formula looks pretty simple:
function triangleArea(a:Number, b:Number, c:Number):Number {
// Check that all arguments are positive and finite.
if (!(a 0) || !(b 0) || !(c 0) || !isFinite(a) ||
!isFinite(b) || !isFinite(c)) {
throw new Error(Invalid argument(s) for triangleArea: +
arguments.join(, ));
}
// Calculate semiperimeter.
var s:Number = (a + b + c) / 2;
// Calculate and return area using Heron's formula.
return Math.sqrt(s * (s - a) * (s - b) * (s - c));

Thanks - all, yes Jake saw it first and others chimed in with the same
thought, my numbers did not compute because they did not make a
triangle. I have it working now.
The formula is fine, and this function works for me as long as the
values come from a true triangle:

return (Math.sqrt((a+b+c)*(b+c-a)*(c+a-b)*(a+b-c)))/4;

Re: [Flashcoders] MX transitions: Website that shows examples?
I've yet to use Fusekit (only used MX tras / tween) and have been quite happy with performance / usability. I realize that Fusekit's API is far more sexy and desireable, but so far haven't seen them do anything that I can't accomodate myself. Such as a Sequence, Parallel, etc. AS3 will also encapsulate most of this functionality in a very handy manner. Not sure about the size / performance ratio, but it's seemed fine to me, from what I've used so far. -Scott On 12/14/06, Merrill, Jason [EMAIL PROTECTED] wrote: I second this testament.

Re: [Flashcoders] MX transitions: Website that shows examples?
Micky Hulse wrote: Anyone know of a similar site that lets you test different variations of the transition classes? Thanks for all the replies all, I really appreciate the advice and links. :) And yes, Fuse looks very cool. Found this vid tut site a while back that does a good job at showing some basics: *Animating with Fuse* http://www.gotoandlearn.com/ But a lot of my projects are very simple (banners, adverts, simple animations)... I find that mx.transitions does the trick (or Tween Extended, see below)... although, if I am ever in a situation where Fuse is the better option, I will most definitely use it (seems like it would be over-kill for the basic stuff.) :) And thanks for the links to the other options... those look nice too. Going to read-up on them now (Transition and tween explorer, and MC Tween.) :D What do you all think about Tween Extended? (Found under AS2 classes) http://www.sqcircle.com/downloads/ Seems like a great way to animate multiple properties at once. I am using it my current project and it seems to work great. So, out of all the above mentioned classes/scripts, what is best? 1. Fuse -- From what I have gathered, this is great for big projects, but not so much for the small things. 2. Transition and tween explorer -- ? 3. MC Tween -- ? 4. Tween Extended -- ? Out of the last 3, which is the better choice? I like the fact that Tween Extended allows for multiple properties on one line... Seems like a must-have feature. Which is the most light-weight? Which is coded better (which would probably mean more light-weight and smaller in file size)? Of course, it sounds like all of this will change with AS3. I can not wait to make the upgrade. :P Many thanks all, I hope your December is going well. :) Cheers, Micky -- Wishlist: http://snipurl.com/vrs9 Switch: http://browsehappy.com/ BCC?: http://snipurl.com/w6f8 My: http://del.icio.us/mhulse ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
