Tinderbox inventory detection or Reset ignite property: I need one!

[Your Computer]

I guess i should have mentioned that this is for my cannon i'm working on for my Teamnesia story. To explain it further, in the level editor i can set a callback (under "CallbackFunc") to the entity, which one of the parameters is capable of providing "OnIgnite" as its value. However, using that method only allows for "igniting" the entity once. If i use SetEntityPlayerInteractCallback(), this allows for lighting the object even without tinderboxes.

I'll use your method for my other custom story, but as you could imagine that method won't work for Teamnesia (at least not without the cooperation of everyone else).
