Legacy GM ERROR: trying to index a variable which is not an array

[SwanBon]

Hi everyone,

I am getting this error every time I click on an item (that the player is able to pick up).

control.item [ index , 8 ] refers to a sprite. When the game starts it is defined:

control.item [ index , 8 ] = null_spr

I assume I am doing something wrong to get this error?

Any help would be great

Thank you

This alone doesn't quite give us much information.
Some more code could help.
Anyways try to use show_debug_message(control.item) and see what it gives you (this outputs a message to the game maker CompileForm on the bottom of your screen).
Btw I guess control is the name of an controller object. I suggest using prefixes like obj_ o_ O, etc.... for readability. You did add something on the end for your other item_obj, so you should stick to naming schemes.
If control was not intended to be an object, than that's your problem. try removing the "control." part. Although I'm guessing that's not the case since it should have given an error saying that the instance doesn't exist.

Just tell me the result of show_debug_message, just put it before your code in draw event and I'll see if that helps finding your problem
