Serious Flash bug?

Question

Hello. I am a newbie to this forum, 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 behavour 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

Answer 1

it's not necessarily a flash bug. there are situations where
assigning your pnt's x and y properties may trigger some other code
to execute and re-assigning those properties immediately afterwards
does not stop the other code from executing.
you need to isolate the minimum code needed to display the
issue before anyone will check it. you're nowhere close to that
