Description

This function is a generic interface to the garbage collector.

collectgarbage(opt,arg)

It performs different functions according to its first argument, opt:

  • "stop": stops the garbage collector
  • "restart": restarts the garbage collector
  • "collect": performs a full garbage-collection cycle
  • "count": returns the total memory in use by Lua (in Kbytes)
  • "step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle
  • "setpause": sets arg as the new value for the pause of the collector. Returns the previous value for pause
  • "setstepmul": sets arg as the new value for the step multiplier of the collector. Returns the previous value for step

Parameters

opt: (string) command for garbage collector mechanism
arg: (varies) additional parameters for command optional

Example

Takes over automatic garbage collection, do it in small steps. Increase/decrease the amount depending on your game

collectgarbage("setstepmul",1000)
collectgarbage()
