Door problem?(NOOB)

If I remember correctly these are the values the function gets delivered. In this case it's the name of the item you're using and the name of the entity you're using it on.
Depends on what you try to achieve whit each function.
If you don't use an item from your inventory to call a function, you don't have to add string &in asItem.

For the beginning you should just look up functions from the original maps and copy their header.
