Just a quick question about performance,
when i load an image or a sound or whatever when I'm done with it to avoid filling up the ram, do i have to get rid of it somehow?

thanks

If your variable is called foo...

Code: Select all

foo = nil

Here's some talk about the Garbage Collection that Lua uses. You don't need to explicitly delete stuff, Lua does it when it realizes you are no longer using it. One of those ways is by making it nil.

If you want to force a full garbage collection cycle for whatever reason, you can do so with collectgarbage("collect")

So you might have like

Code: Select all

wholebunchofimagesinatable = nil
collectgarbage("collect")
loadnewimages()

or something... It's not necessary 99% of the time though.

To make sure you don't use collectgarbage('collect') unnecessarily: if you have to ask, you shouldn't use it.
