Vm sprite
This is used to determine the ID of the current sprite. This is identical to "THISACTOR" in most cases (however "THISACTOR" is read-only).
Changing this value is useful for commands that only affect the current sprite, which is true for all commands in the original CON v1.5.
It can also be used for when making a loop through all sprites. Example:
appendevent EVENT_WORLD for My_Sprite allsprites { setuserdef[].vm_sprite My_Sprite [...] } endevent
