hi!

i think we need some kind of destructor code for entities. let's say we have allocated some memory within the entity's action. now we need a way to delete the allocated memory on destruction of the entity. having wrapper functions for ptr_remve (ent_remove) is not always an option, because we cannot hook when the engine deletes entities on level change, for example. this would be a great feature.

joey.

An easy solution is walking the entity list with ent_next on level change, and freeing the memory.
