FTE's QuakeWorld player movement (PM_PlayerMove): one command of a player's input moving a box through the world and the entities near it.

pm = QuakeServer.Pmove.player_move(pm)

The caller fills a QuakeServer.Pmove with the player's state, the command (QuakeServer.Pmove.Command), the movement settings (QuakeServer.Pmove.Movevars) and the things it can meet (physents, a tuple of QuakeServer.Pmove.Physent, the world first), and reads the state back.

• pm_type — :normal, :dead (no acceleration, no jumping), :fly (flying, bumping into walls), :none and :freeze (no movement), :spectator and :old_spectator (flying through everything; the old one stops moving while at speed), :wallwalk (the wall under the player is the ground) or :six_dof
• gravitydir — the way down; a zero vector is taken as {0, 0, -1}
• onground, groundent (an index into physents) and groundplane (its normal) — what the player stands on
• waterlevel 0 to 3 and watertype, the contents bits (QuakeServer.Contents) at the player's feet
• onladder — set on reaching a ladder; only the caller clears it
• jump_held, jump_msec, waterjumptime — the jump button's state and the seconds left of a jump out of water
• safeorigin — the last spot the player was found to fit, where a stuck player is returned when safeorigin_known
• touched — indexes into physents of what the move ran into, newest first
