Set a sidedef's midtexture to "TRIPWIRE" to turn that line
into a tripwire.
Players can't drive through a tripwire and will bounce
back at high speed if they're in one of the following
states:
1. Invincibility / Grow
2. Sneakers
3. Flame Shield dash
4. >200% on the speedometer
Hitting a tripwire plays a sound, sends you into hitlag,
then plays another sound when the hitlag is over. The
sounds used depend on whether you can drive through the
tripwire.
Values are subject to tweaking.
(AngleDelta stuff is a leftover of the previous attempt, but I think the code's useful so I kept it in this commit anyway)
All my work thus far on solving the drawflag/renderflag/additive/subtractive conundrum.
Outstandng problems:
* Bad additive/subtractive tables means that they appear opaque except under certain conditions.
* No support for FOFs, Polyobjects, or linedefs in OpenGL yet.
* All OpenGL support mostly done blind, may or may not function in practice.
If nothing else, the hard engineering problems are solved and it's just bug hammering...
* 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.
It's no secret that holding down a button a lot can fuck with your wrists and fingers. It's too late for me to be damageless, but I can at least create an option to reduce further harm.
This accessibility feature, when enabled (kickstartaccel and kickstartaccel2/3/4 in the console) behaves with the following properties:
* Hold accelerate for 1 second to lock it down.
* Press again to release.
* Short holds/presses do nothing (good for POSITION).
* Continue holding it during the releasing press to re-lock it.
* A small triangular UI element is added next to the speedometer sticker, which displays the current state of the acceleration kickstart for visual feedback. (NO SPLITS SUPPORT YET)
In addition:
* Add PF_ACCELDOWN and PF_BRAKEDOWN, and BT_REALACCELERATE (which ACCELDOWN tracks). Even if this feature never gets merged, BT_REALACCELERATE is required because sneakers and boosters force it on too (extending this is how I implemented it).
* Fix the dehacked playerflag list being out of shape.
* I replaced some existing flags during development of this branch, so their old uses have been whittled away.
* Becoming a spectator is now instant, and leaves no bumpable corpse behind.
* Players will now FAULT if they:
* change from a spectator into a player after the initial camera turnaround but before the end of POSITION.
* touch an instant kill FOF or get crushed during POSITION.
* become a spectator during POSITION. (I might change this later, seems overkill)
* If you respawn during POSITION, the jingle will not restart from the beginning.
* Change the FAULT animation to match spinout/currents.
* Clean up some of the spawning code to not place spectators on the ground.
