/** A simple brain used to steer the player around without regard |
|
for physics. Used in production to quickly fly through a scene |
|
without having to actually solve puzzles, jump, etc. |
|
The 'Drive Brain' uses the same input keys as the avatar, with |
|
a few secret additions for convenience. At the time of this |
|
writing, you invoke the drive brain by pressing shift-P, and |
|
then use the forward and back arrows to move and th e left and |
|
right arrows to rotate. The 'u' and 'j' keys will move your avatar |
|
vertically. |
|
Gravity and collision are completely suspended for avatars in |
|
drive mode, but they *can* still trigger region detectors if |
|
you need to fire off triggers, puzzles, or whatnot. |
|
Note that the drive brain inherits from the user brain, which |
|
parses control input for us. |
