private function example(param1:int, param2:int):int
{
var var1:Object = null;
var var2:int = -1;
param2--;
for (;;)
{
if (var1.x + var1.y > 0 && param1 < 0)
{
return var2 + 5;
}
}
return var2;
}
is decompiled as
private function example(param1:int, param2:int) : int {
var var1:Object = null;
var var2:* = -1;
param2--;
while(!(var1.x + var1.y > 0 && param1 < 0))
{
}
return var2 + 5;
}

Main.as (1 KiB)May I ask you what's the fucking point in attaching the source code instead of the
compiled swf?
Please do not use coarse language here, thanks.
I think it is not a problem in this particular case, because the example is simple and I
can easily compile it myself.
Ok... I took another look on the code now (after 2 years) and found these two codes
equal:
In your code the "return var2" is never reached, so it is is correctly ignored by the
decompiler.
Your for loop breaks only when the if condition is met => (var1.x + var1.y > 0 && param1 <
0)
So in fact, the loop continues when inverse loop is met => !(var1.x + var1.y > 0 && param1
< 0)
Both codes are equivalent and I cannot distingish between them.
If you agree I'll close this issue.
