That script works well, but It doesnt really work for my situation, I need it to add the actor just by being present in your inventory, and removes actor when you sell it, the need to equip conflicts with my current set up

If you don't mind about having a parallel process running this can be achieved very easily with a Conditional Branch (if Item X is in inventory add actor X / else remove it).

hey so this does work but I found now that for whatever reason your script gives me this error only when I try to run a Battle Test

 

Script 'Cache' line 88 :NoMethodError occured

 

Undefined method `empty?' for nil:NilClass

 

If you don't mind about having a parallel process running this can be achieved very easily with a Conditional Branch (if Item X is in inventory add actor X / else remove it).

 

Wow, I prefered to script it but since i ran into that problem, The parralel process works a lot better, never thought to do that
