You’ve got a point named HitBox with a capital B in the middle of the word :
Your event has the Hitbox name with a lower case b in the middle :
They are treated as 2 different strings. You’ll have to change one of them to match the other.
I’ll try it right now
Yes, and excellent 
you always help me even though in the end it was my fault, thank you. And if you don’t mind, can you link 1 object with 2 different objects?
I haven’t tried, but I can’t see why not. If behind the scenes linking stores the objects by id in a dictionary, then it should be possible. You’d have to iterate through each object type in a separate loop though to get the objects that have been linked.
oh, I see. and actually, i have one problem where i can’t delete the object, i don’t know why, even though the required condition has been reached, but i guess i’ll cover this in another topic
