Scripting with if-clauses

[ThePaSch]

Maybe I entered the name "lantern" in the wrong fields? I've entered it in General > Name, Entity > CallbackFunc and Entity > PlayerInteractCallback.

You don't put the entity's name into CallbackFunc and PlayerInteractCallback. These fields are for what their name suggests they are, for callbacks. Just like the callback you set up when the player and the area collide.

For the record, you didn't include the quotation marks at General > Name, did you?
