The player physics files define a variety of different variables relating specifically to how the player moves throughout the game world. The values will control, movement speed, jump height, long-jump speed, and much more. Player physics is split into three different files, all containing the same variables: the first, playerphysics.txt, is the standard physics for the player when moving around levels, on ground and in air; the second, playerphysics_lowgrav.txt, is the physics used when the player is within a gravitational-pull beam; and the third, playerphysics_water.txt, is the physics applied when the player is currently in a liquid (water, or toxic water). The variables contained within these three files are as follows:

• gravity - The gravity applied to the player normally.
• leniency - The amount of time a player can fall through the air and still jump.
• max_fallspeed - The maximum speed the player can reach whilst fall.
• maxspeed - ???
• runspeed - The maximum movement speed of the player.
• ground_friction - The friction applied to turning whilst on the ground.
• stop_friction - How quickly the player stops moving after releasing a move key.
• air_friction - The friction applied to turning whilst in the air.
• fastfall_gravity - The gravity applied to the player whilst fast-falling.
• fastfall_jerkdown - Inital jerkdown force applied to the player when fast-fall is initiated.
• fastfall_maxspeed - The maximum speed the player can reach whilst fast-falling.
• float_time - ???
• jumpheight - The max height of the player’s jump.
• release_jumpheight - The height of the player’s short hop (tapping the jump button).
• longjump_slidethreshold - ???
• longjump_speed - The speed at which the player moves during a long jump.
• longjump_height - The height gained when performing a long jump from a ledge.
• longjump_airfriction - The friction applied to turning during a long jump.
• ledgejump_height - The height gained from a normal ledge jump (not a long jump).
• enemy_bounceheight_nojump - The height gained by the player when bouncing off an enemy.
• enemy_bounceheight_jump - The height gained by the player when bouncing off an enemy with a jump.
• mush_bounceheight_nojump - The height gained by the player when bouncing off a spring.
• mush_bounceheight_jump - The height gained by the player when bouncing off a spring with a jump.
• enemy_prebounce_time - ???
• enemy_postbounce_time - How long the "no jump" bounce force is applied for? (Impacts no jump bounce height.)
• swimspeed - The speed the player moves horizontally in the water.
• water_exitheight - The height gained when jumping out of the water.
