The problem might be in you lock tile script. Its probly the part of the code that should say like ChangeTile ,#$00,#$00

if you post your lock tile code, we can figure it out.

if you post your lock tile code, we can figure it out.

i made sure i had a var called myKeys and that var is element 5 in the hud. As i stated before. I can pick up the key and when i approach the lockbox. my keys go down to 0. the only thing is my lockbox doesn't change appreance or turn into Null-Walkable

;;;;;;; THIS PRESUMES YOU HAVE A VARIABLE CALLED myKeys
;;;;;;; PRESUMES THAT VARIABLE FOR KEYS IS DRAWN IN ELEMENT 5
