FATAL ERROR: Could not load script file

[Romulator]

The error code tells you your issue and apparently they are on your third line. Key and Door are not declared.

Look at your script's 3rd line: the AddUseItemCallback.

The script telling you that they are not declared means that the script thinks you're referencing something else in the .hps file. Really, all that you have done is forget to put them in quotation marks ( "" ) because they are string references. Provided you have an entity named "Key" and "Door" in your Level Editor, this should work.

PHP Code: (Select All)

AddUseItemCallback("", "Key", "Door", "UseKeyOnDoor", true);
