* Introducing K_GetKartButtons(player_t), for adding false presses to.
* K_GetForwardMove(player_t) takes kickstarting into account, and is now applied to engine sound generation too.
* BT_REALACCELERATE has been deleted.
The old condition for player movement was...
1. player hasn't finished
2. player not in pain, or player in pain but on the ground
The else condition to this is therefore player has finished or player in pain
and in the air.
I believe K_MomentumToFacing (prior to bots) was only for letting the player
turn around after crossing the finish line, to face the camera.
(K_MomentumToFacing also does nothing in the air.)
- Fixed the bugs with them in our last netgame
- Karma bombs are no longer slippery or have stat changes
- Karma bombs cannot pick up spheres. Their remaining spheres before they died are removed 1 per tic.
- Karma bombs are out of the game permanently when touching the overtime barrier
- When successfully hurting another player, instead of getting 0.5 bumpers, they steal ALL of the opponent's bumpers, effectively swapping places with them. One bumper is lost in the process, meaning bumpers are slowly flitered out the more people need to come back.
- Removed karma items/eggboxes... hopefully this is temporary and we can bring them back later, but currently we don't have a design for how they should work under the new rules :x. They are still in the code behind the `OTHERKARMAMODES` define
- Bumpers & comeback timer are now player_t variables instead of kartstuff shit
- eliminated boolean on player_t for checking when a player touched the barrier
Kart's manual player friction adjustments were being called after movefactor was reset, meaning friction changed but movefactor was default, essentially creating old 2.1 friction again
Instead of doing its best to avoid P_DamageMobj, it embraces it, using the damagetype system to decide how the player takes damage. Overall less stupid.
My rewrites clean up a LOT of weird/misleading behavior anyway, so I'm gonna push this regardless. Someone else will have to figure out another way to reimplement braking friction though -- we can't use it as is because it prevents being able to bump people.
- Split HUD stuff into k_hud.c/h
- V_SPLITSCREEN replaces the old function that sets V_SPLITSCREEN/V_HORZSCREEN flags system, and instead automatically moves it based on player number
- V_SLIDEIN makes HUD items slide in after the intro animation.
New function specifically for dropping rocketsneakers K_DropRocketSneaker
Used by Eggbox touchspecial to properly dispose of shoes and clean up hnext
Now also used by the shoe thinker to drop themselves
Fixes angle of spent shoe launch
