Looking for someone experienced with memory leaks

[HelloFlighty]

Hi, just wondering if anyone would be willing to help me go through each of my triggers 1 by 1 to help me find and fix any leaks that may be present? As far as my knowledge goes of memory leaks there are a quite a few of these triggers that don't leak since they don't use any of the known "leaky" actions, however there are a decent number of triggers that DO use actions that I think leak and would seriously appreciate the help in fixing them since I'm incredibly close to being able to release a beta/test map.
If anyone is willing to pick up the challenge then I'm grateful, triggers will be posted below.

To clarify, my map is a TD.

There are a few other triggers as well but they don't use commands that create units nor order them to move or anything of the sort, they're mostly just changing variables depending on ingame events so i left them out.

 

[Wark]

There are memory leaks in these triggers:
1) Create a temporary player group after a temporary unit group, then remove both (at the top)
3) Remove the special effect after its creation (Destroy last created special effect)
4) Player start location needs to be made into a temp point, then removed
5) Same as 3, remove the special effect
7) Declare then remove the points used for creating the units, or preset those points at map initialization. You may need to remove the temporary region as well unless it is permanent or preset


On a side note: you do not need to remove unit groups or points that you use multiple times. It's actually more efficient that way.

 

[Pyrogasm]

For reference: Things That Leak

• Trigger 1: you create the "Players" group but you appear not to use it consistently later in the other triggers. A lot of things that are (All Players) should probably be Players, though that really doesn't change much. The leak Wark pointed out in 1 is "Enemies of Player 21 (Coal)" which you remove with call DestroyForce(udg_TEMPFORCE)
• Trigger 2: fine
• Trigger 3: In addition to leaking the SFX at the start you leak a location: (Position of (Triggering unit)). Depending on how the mass teleport model is, destroying it immediately as Wark suggested might cause it not to display anything at all. If that's the case you can save it in a GUI shadowed local variable
• Trigger 4: nothing further
• Trigger 5: same caveat about the effect maybe not showing up as with 3.
• Trigger 6: Center of Relay1 <gen> leaks, but as Wark suggested instead of cleaning the point every time it's probably better to set it at map init and then just reuse the point variable every time you need to and never remove it.
• Trigger 7: there are also point leaks in the order action. Again it would definitely be better to just store and re-use these points rather than loading a random region and getting its center point. I don't think Wark is correct that the region is a leak here, since it's just a reference to it and not actually creating new data from the hashtable (same handle ID). If I'm wrong about this someone please correct me. It seems analogous if anything to the non-nulled-local-variable-before-function-end leak. Either way, saving the points instead of regions in your hashtable would avoid this question/issue altogether.
• Trigger 8: you leak the floating texts and I'm not sure you're properly giving them a lifetime. See this post.

Many of your gold-modifying actions can be simplified. There is a "modify property" action instead of a "set property" action, which allows you to do: Player - Add GoldPerKill to (Owner of (Killing Unit)) current gold instead of the 'set to old + additional' method you've written.
