> What steps will reproduce the problem?
Open SWF, edit ActionScript.
Save and close.
Open the edited SWF and export the ActionScript you edited.
Compare original to new.
Observe the extra lines.
Here's a sample of the original:
var _loc5_ = 0;
while(_loc5_ < itemsArray.length)
{
_loc5_;
var _loc11_ = itemsArray[_loc5_++];
_loc5_;
var _loc12_ = Number(itemsArray[_loc5_++]);
_loc5_;
var _loc10_ = Number(itemsArray[_loc5_++]) * 1000;
_loc5_;
var _loc8_ = Number(itemsArray[_loc5_++]);
_loc5_;
var _loc13_ = Number(itemsArray[_loc5_++]);
var _loc3_ = dialog.pickpocket["slot" + _loc8_];
if(_loc3_)
{
if(_loc13_ == 1)
Here's a sample of the edited:
var _loc17_ = 0;
while(_loc17_ < itemsArray.length)
{
_loc17_;
_loc17_;
var _loc18_ = itemsArray[_loc17_++];
_loc17_;
_loc17_;
var _loc19_ = Number(itemsArray[_loc17_++]);
_loc17_;
_loc17_;
var _loc20_ = Number(itemsArray[_loc17_++]) * 1000;
_loc17_;
_loc17_;
var _loc21_ = Number(itemsArray[_loc17_++]);
_loc17_;
_loc17_;
var _loc22_ = Number(itemsArray[_loc17_++]);
var _loc23_ = dialog.pickpocket["slot" + _loc21_];
if(_loc23_)
{
if(_loc22_ == 1)
See how each _loc17_; are doubled?

Not to insert these extra lines.

do you have?

Added the SWF file I used in the sample above.
The sample is taken starting line 395.
hud.gfx.swf (103 KiB)
Which script is this from?
You said line 395, but which script?
I don't see anything similar like the sample you written in this SWF file.
How do you mean?
I see only one 'DoAction' script under 'frame 1'.
You wrote:
"Here's a sample of the original:
var _loc5_ = 0;
while(_loc5_ < itemsArray.length)
...
""
What do you mean by original?
You mean the original code that is in this SWF file?
I don't see this kind of code anywhere in the SWF file you attached.
Or is this a new code you are trying to insert?
Are you sure you attached the correct SWF?
I don't see anything like for example "pickpocket" in it.
Please explain the exact steps how to reproduce it on this swf file.
Okay i see the following as simple code that reproduces the bug on any script:
function myFunc()
{
_root.test = 5; //triggers DefineFunction2
var _loc2_ = 0;
var _loc3_ = {};
//after compilation, it inserts _loc2_ in this place
var _loc4_ = _loc3_[_loc2_++];
}
So now I can try to fix it...
Okay, it should be fixed in nightly 2823, try it.

Works for me, thanks!
