recursive_set_attack

Calling set_attack inside set_attack.gml can cause an infinite loop and crash.

//set_attack.gml
set_attack(AT_NAIR) // WARN: Risk of crash. in `attack_set.gml` you can just write `attack = x` instead of `set_attack(x)`.

Resolution

Assign attack instead. set_attack(AT_NAIR) could be replaced with attack = AT_NAIR.

If the set_attack.gml logic is particularly complicated you may need to reorder things..
