Final answer:
The DestroyActor function is used to remove an actor instance from the level in game development platforms.
Step-by-step explanation:
The DestroyActor function is used in various game development platforms, such as Unreal Engine, to remove an actor instance from the level. When this function is called, the target actor is immediately scheduled for deletion. This means that it will be removed from the game world, and no longer be visible or interactive within the level. It's a crucial aspect of memory management and gameplay dynamics, as developers have to ensure that only necessary actors exist in the level at any given time to optimize performance and gameplay logic.
