Hi all,
I've discovered serious memory leaks on collition systems when i remove from definitions PUAP_SCRIPT_CHANGE... .I did the tests from version 1.1 to version 1.4 of iTgb (and all have the same problem)
In my game I've memory leaks of approximately 1 MB per minute... :-(
If anyone can solve it.... to recreate the problem simply install the "iPhoneTest", with leaks Instruments and use the bounce mode.
After a few minutes you will notice a significant loss of memory.
In a game like mine where there are many collisions per second causes a crash after a few minutes.
I can't use PUAP_SCRIPT_CHANGE because my game is based on PSK: www.torquepowered.com/community/forums/viewthread/112599/1#comment-733991
I USE IN TEST THIS DEFINITIONS:
__IPHONE__
TORQUE_PLAYER
TORQUE_RELEASE
TORQUE_DISABLE_MEMORY_MANAGER
PUAP_OPTIMIZE
USE_COMPONENTS
This is a screenshoot of my instruments :

@Edoardo - I'll investigate the issue to see what can be reproduced on our side. Again, right now I'll only be able to test against the base engine until I have more time to give this a run with the PSK integration. Whatever findings we come up with I'll post here.

To resolve the issue you can use iphoneTest only.

@Michael, If you resolve the engine collisions bug (without the use of PUAP_SCRIPT_CHANGE) I'm sure that PSK work fine!To resolve the issue you can use iphoneTest only.

I haven't had much time to really dig into this myself, but I know Luma has looked into it. The entire team is slammed right now, but we see your e-mails.

We too have disabled PUAP_SCRIPT_CHANGE and are seeing significant memory leaks.

I've been using iTorque 1.3.1 but downloading & looking at the code [for 1.4] the problem still appears to be present.
If any Torque developer is reading where can I send the modified Dictionary.h and Dictionary.cc?
EDIT: note the version I checked--1.4

I've got a fix for this problem (disabling PUAP_SCRIPT_CHANGED causes the scripting engine to leak memory).I've been using iTorque 1.3.1 but downloading & looking at the code [for 1.4] the problem still appears to be present.

What is the fix to this issue? I didn't see an official solution other than Phillip fixed it.

Hey Darren, I didn't fix it. I modified the PSK so that users weren't required to disable PUAP_SCRIPT_CHANGED. I'm not sure if there is a fix available or now.

The changes aren't very localised within the affected files. Is there somewhere I could email it?

FYI, addressing these leaks is my final step before releasing my game. Will post within the next week or so when it's in the store.
