Here refers to anything that can be garbage collected and not general object instances as defined in the Asset Browser). The general idea is that objects which hang around for a while don't need to be continuously tested to see if they should be deleted, but can be checked less frequently (note that 'objects' They are moved into older generations as they themselves age. New objects are created in generation 0 and This means that, in order to reduce the work that must be done every frame, objects are divided into 'generations'. The garbage collection which GameMaker Studio 2 uses is 'generational'. TheВ garbage collector, but still need to have their destroy function called. The exceptions to this are sequences, animation curves and instances, which also require If anything you create at run time has a destroy function then it won't be garbage collected and you will have to deal with it yourself in code. NOTE: Please note that things like surfaces, data structures, buffers and other dynamic resources are not garbage collected and have their own destroy functions to clean up the memory associated with them.

Also note thatДЇunctions defined in scripts in the IDE are also not collected, as they are implicitly made global. Generally refer toВ any struct or function which isn't connected (it doesn't have to be directly, but through a chain of other variables) to a global variable or an object instance variable.

When we talk about something being de-referenced, we This is where the garbage collector comes in and it will run in the background of the game, collecting anything that's been de-referenced and maintaining an optimal memory usage.

The GameMaker Studio 2 Garbage Collector exists because methods can be passed on the stack and left unreferenced, as can structs and a few other things, which in turn would cause a memory leak if they weren't 'cleaned up'
