Illustrates some of the versatility of func_doors, using Optimus Prime from the Transformers.
Press the button to transform Optimus Prime back and forth.
Paticularly important is the use of "lip" and "-lip" fields, pitch and yaw, and the 'x or y axis' flag for func_door rotating.
Thanks to Seventh-Monkey for the information about negative lip. When a positive amount entered for a sliding door leaves the door partially closed, entering a negative amount for this field allows the door to open wider than usual.
I deleted the other map that was part of this download and appropriately, just left the example map.
Thanks for comments!
