Memory optimization

[Rekindled Phoenix]

I wrote a small bit of code to cycle though a collection of entities and draw lines between their positions. The objects were not creating any new meshes, only drawing and looping through collections. I had the fortunate mistake of leaving my computer on while eating lunch, and encountered an out of memory exception within the Sandbox. So I ask...

 

1. When is the optimal place to use local? What object datatypes are best, if any?

 

2. Is it possible calling functions within another function delays the garbage collector?

 

3. using collection = classnametable["info_pathing_node"], can I call this once and reuse it? Or do I have to create it every loop in case a new object was added?

 

4. Will calling AddHook() with a function cause a small memory leak over time?

do you do garbage collection any where in your script?

 

see this post that had the same problem with the viperscript and the modified oildrum scripts: http://www.leadwerks.com/werkspace/topic/2178-mem-usage-grows-continuously/page__view__findpost__p__20049

I didn't think that I would have to manually call the garbage collector for a script engine... but whatever works!

 

collectgarbage(collect) should work if I'm specifying the exact objects in quesiton.

Can anyone answer the other questions?

1. Inside of a function is the best place, but mainly in an object script at the very top doing all your initial declarations, you don't have to assign variables at that point either, just best to have them declared locally before you do anything else.

 

2. Nope, its stack based.

 

3.You can reused something like that though it depends on if you deleted collection. As long as it isnt nil it will overwrite each loop without you redeclaring.

 

4. Can't answer, don't know how it was coded.

Thank you Tyler, those questions have been numbing my mind for the last couple of days.
