Movement styles

A movement style is a complete set of movement physics. It changes acceleration, air control, jumping and what tricks exist, and race records are kept separately for each one.

There are nineteen, defined as the MV_* enum in bg_public.h. The descriptions below follow docs/Defrag Mapping Guide.md, which ships on the source branch. It is jaPRO’s own guide, carried downstream with the gamecode rather than written here. That makes it worth following because it is the account of the person who built the styles.

The styles

Style	Derived from	How it plays
`siege`	JKA siege mode	No air acceleration. Speed comes from rolling, ramps and wall-strafing.
`jka`	—	Default Jedi Academy movement.
`qw`	QuakeWorld	QuakeWorld turning with JKA force jump. Tighter turns without losing speed, plus ramp jumps.
`cpm`	CPM, via Q3 defrag	No force jumps, base speed 320, high air control, rampjumps, double jumps.
`q3`	Vanilla Q3 defrag	CPM without the increased air control.
`pjk`	CPM	CPM with force jump and normal JKA base speed.
`wsw`	Warsow / Warfork	CPM plus a dash and a walljump, which redirect your speed to any angle without losing it. Its ramp jump costs no horizontal speed either.
`rjq3`	Q3	Q3 with a rocket launcher, moving by self-knockback.
`rjcpm`	RJQ3	RJQ3 with air control.
`swoop`	—	Riding a swoop bike, with a gravity-boost option.
`jetpack`	—	Jetpack with its own physics, plus a swinging grapple and detpacks for self-boost.
`speed`	JKA	JKA at force-speed base speed, with 50 non-regenerating force.
`sp`	Jedi Academy single-player	Higher air acceleration; landing halves your speed unless you land lower than you took off.
`slick`	—	No ground friction and very fast ground acceleration. No force jump.
`botcpm`	CPM	CPM with a button that makes your strafe angles perfect.
`coop`	JKA	Two-player mode with weapons that boost each other.
`ocpm`	CPM, via Q3 defrag	CPM made closer to Q3 defrag’s: 125 fps physics and velocity snapping.
`tribes`	Tribes	Skiing and jetpacking, a self-boost gun and a thrust pack. See Tribes.
`surf`	Counter-Strike 1.6	For surf and bhop maps.

Four rows carry no lineage because none is stated anywhere in the tree. jka is the base game’s own movement and needs none; swoop, jetpack and slick are described by what they do rather than what they were modelled on. Rather than invent an inspiration for them, they are left as the guide states them.

Choosing a style

Players pick their own style with /move, which the server implements (g_cmds.c):

move <siege, jka, qw, cpm, q3, pjk, wsw, rjq3, rjcpm, swoop, jetpack,
      speed, sp, slick, botcpm, coop, ocpm, tribes, or surf>

Run it with no argument and it prints exactly that list, which is the quickest way to see what your server accepts.

Four conditions must hold, and the command tells you which one you failed (Cmd_MovementStyle_f):

The server must have race mode enabled (g_raceMode).
You must be in racemode yourself, not just on a server that allows it.
You must be alive, not dead or spectating.
You must be standing still. Any velocity and it refuses.

That last one catches people out. Try it while you are still drifting and the style does not change; the only sign is the refusal printed to your console.

Outside racemode there is no per-player choice: g_movementStyle picks the style for everyone, clamped to the enum. Below the first style it falls back to siege, and at or past the end of it to jka (bg_pmove.c). In racemode your own STAT_MOVEMENTSTYLE wins instead, which is how one race server runs different physics per player and keeps a leaderboard per style. Racing on jaPRO covers the rest of a race server: practice mode, accounts, leaderboards and strafe trails.

Style is a game-module concern, so what you can select depends on the server. The client draws what it is told; see the overview for where that boundary runs.
