(This document covers version 2.0.1 of the 'Fly' behavior, current as of 2005-Feb-11)
Description
Attach this behavior to an object to control its movement with the keyboard. (Typically attached to a Camera to allow the user to ‘fly’ around in the scene.)
This new version allows you to control forward/backward movement, left/right turning, left/right sliding (‘strafing’), and up/down sliding.
If
Stop Without Gas?
is checked, the object will immediately stop moving as soon as any of the movement keys are released.
If
Slow Without Gas?
is checked, the object will slow to a stop (using the
Acceleration
value to slow down) when the movement keys are released. (Provides a natural feeling of inertia.)
If neither of the above are checked, the object will continue moving and sliding until the
Stop Key
(slows to a stop) or
Full Stop Key
(immediately stop all movement) are pressed.
If
Move in XZ plane only?
is checked, the movement will be constrained to the ‘horizontal’ plane. This allows you to have the camera point down (someone looking down) without having the
Forward Key
move the camera along that path. If not checked, the object will always move ‘forward’ in the direction it is ‘looking’.
See ‘Appendix C: Key Names’ for a full listing of strings which may be used for each of the key mappings (in advanced properties).
This behavior does not modify pitch or roll, but may be used in conjunction with another behavior (such as Tumble or Mouse-Controlled Incrementor) to affect these values.
This behavior is commonly used in conjunction with Collider for Walkthroughs to allow the user to move through a scene without walking through walls.
