Hello everyone! I'm having trouble with my achievement system that I can't seem to fix. I've tried a lot of different things but nothing seems to work. so I'm just going to show you my code and hopefully you can help. If your not sure what some of the code means, ask me and I will explain it

Error:

Make sure you don't accidentally delete your backpack after you create it.

In your create event you are creating your backpack_slots correctly,
the problem is that you delete again right after by writing

backpack_slot = noone;
backpack_slot_n = 0;

Those 2 lines should be before the for-loop that creates your backpack.

Thank you so much, it works.
