Create a new program called “factory.py”. Start by disabling the mouse and then place the camera at (1,-8,5) with a pitch of -25 degrees. Then define a class called World that derives from DirectObject (this allows World to receive events). In the constructor of the World class load and display two models: ./Models/factoryfloor.egg and ./Models/box.egg. Position the box at (1,0,2), scale it down to 30% and give it a heading of 45 degrees. Make sure you can see both the floor and the box.

The floor contains a door object. Acquire a pathnode to it and call it door. Create two LerpPosIntervals for the door, one to open it by moving it to location (-1,0,0) and one to close it by moving it to location (1,0,0). You can play with the duration but 2.0 seconds is a good place to start. Make the World accept a 'space' (spacebar key) event and call a handler called self.door_handler. In that handler, either start the opening interval for the door or the closing interval, depending on whether it's open or closed already (you'll need a new boolean member variable to keep track of that).

and then attach a new CollisionNode to that pathnode
