|
|
*
|
|
* 12 11/10/98 5:17p Jeff
|
|
* peppered in some more forcefeedback effects
|
|

|
|
* Fixed known ground plane issues and used PhysCalcGround everywhere
|
|
*
|
|
* 9 8/27/98 6:23p Jeff
|
|
* changed autoleveling in config so it is a slider...had to convert
|
|
* global from bool->uint8_t. Added fast headlight and mirrored surfaces to
|
|
* config menu
|
|

|
* Added a walking sim
|
|
*
|
|
* 2 9/11/97 12:43p Chris
|
|
* Added new support for face_physics_info from room.h. Also, changed how
|
|
* we detect portals. Also added recorded faces.
|
|
*
|
|
* 6 3/27/97 10:50a Chris
|
|
* Added bounce constant (PHYSICS_BOUNCE_UNLIMITED) for objects that can
|
|
* bounce forever
