Trying to open and close a door with a lever

[jens]

The easiest way to make a lever control a door is to make a special door that is a move object. For examples of this look in the game at for example the secrect passage in the second level, where a shelf rotates open and part of the wall behind it slides up.

What you basically needs is a special entity (look at above entities for examples) and special scripts (check the script file for level 2).
