* Revision 2.11 2005/12/14 08:07:33 phreak
|
|
* Handling of exit explosions for beams when a ship is about to get destroyed, or according to the code: "tooled".
|
|
* Bumped beam frame collisions to 10 to compensate.
|
|
*
|
|

|
|
*
|
|
* Revision 2.8 2004/08/11 05:06:36 Kazan
|
|
* added preprocdefines.h to prevent what happened with fred -- make sure to make all fred2 headers include this file as the _first_ include -- i have already modified fs2 files to do this
|
|
*
|
|
* Revision 2.7 2004/03/17 04:07:32 bobboau
|
|
* new fighter beam code
|
|
* fixed old after burner trails
|
|
* had to bump a few limits, working on some dynamic solutions
|
|
* a few fixed to background POF rendering
|
|
* fixing asorted bugs
|
|
*
|

|
|
*
|
|
* Revision 2.4 2002/11/14 04:18:17 bobboau
|
|
* added warp model and type 1 glow points
|
|
* and well as made the new glow file type,
|
|
* some general improvement to fighter beams,
|
|
*
|
|
* Revision 2.3 2002/10/19 19:29:29 bobboau
|
|
* initial commit, trying to get most of my stuff into FSO, there should be most of my fighter beam, beam rendering, beam shield hit, ABtrails, and ssm stuff. one thing you should be happy to know is the beam texture tileing is now set in the beam section section of the weapon table entry

|
|
*
|
|
* 6 1/24/99 11:37p Dave

|
|
* FRED. Sort of works :(
|
|
*
|
|
* 3 1/12/99 12:53a Dave
|
|
* More work on beam weapons - made collision detection very efficient -
|
|
* collide against all object types properly - made 3 movement types
|
|
* smooth. Put in test code to check for possible non-darkening pixels on
|
|
* object textures.
|
|
*
|
|
* 2 1/08/99 2:08p Dave
|
|
* Fixed software rendering for pofview. Super early support for AWACS and
|
|
* beam weapons.
