Re: [Flashcoders] This actionscript error is driving me mad

Dear Zeh, thank you for your reply.

2007/12/30, Zeh Fernando [EMAIL PROTECTED]:

 var p1:Point = new Point(10, 20);
 var p2:Point = p1; // not a copy, but a reference
 p2.x = 0;
 trave (p1.x); // traces 0, not 10

 That's the only thing I can imagine. I guess it will depends on what's
 on the [snip] part of your code. Is anything (that's also part of the
 pathB array) assigned to pnt?


Unfortunately, pnt is not assigned anywhere else. It only appears in those
lines of code I have already sent.
If I replace them with pnt.x=pnt.x; pnt.y=pnt.y; the code works fine! But
anything else fails.

I am thinking this could be an internal Flash bug. Where should I report
this? I am willing to send all of my code if this could help tracing out the
bug.

BTW, happy new year! :)

[Flashcoders] This actionscript error is driving me mad

[Bill Kotsias]

Hello. I am a newbie to this list, so I am sorry if this message is
off-topic. If it is, I would be obliged if anyone could direct me to the
correct place.

I am a veteran programmer but I am new to actionscript. I have come across
some strange behaviour which is driving me mad. Following is a part of my
code :

...[snip]...
private var pnt:Point = new Point();
private var dirp:int;
private var fastp:int;
private var i:int;
private var pathB:Array;
...[snip]...
for (dirp=fastp; dirp=i; dirp++) {
   // BUG!!! If I UNCOMMENT 1 of the 2 following lines, code gets mixed up.
   // pnt.x=pathB[dirp][0].x+pathB[dirp][2].x;
   // pnt.y=pathB[dirp][0].y+pathB[dirp][2].y;
pnt=new
Point(pathB[dirp][0].x+pathB[dirp][2].x,pathB[dirp][0].y+pathB[dirp][2].y);
if (addElement(pnt, dirp, pathB[dirp][2], pathB[dirp][3]+1))
return pathF;
}

As I mention above, if I uncomment //pnt.x=... or //pnt.y=... or if I even
replace them with something like pnt.x=pnt.x+1;
then my code gets mixed up and returns wrong results.

This is driving me nuts because these two lines shouldn't have any effect
since right below them there is
pnt=new Point(...);
which supposedly cancels the 2 previous instructions. Right?

Could anyone, please, show me the obvious that I can't see?

Many thanks in advance,

Bill Kotsias
