input

  • ESCAPE = Unlock Mouse
  • N = New Game and Car Color
  • W,A,S,D = Drive Car
  • Space = Brake
  • L-Shift = Boost
  • RIGHT CLICK/MOUSE4 = Zoom Snap Close/Ariel
  • Mouse Scroll = Zoom in/out
  • C = Random Car Colors

  • F = FPS to console
  • P = Player stats to console
  • O = Toggle auto drive

config

It is possible to tweak the car physics by creating a config.txt file in the exec/working directory of the game, here is an example of such config file with the default car physics variables.

maxspeed 0.0265
acceleration 0.0028
inertia 0.0022
drag 0.00038
steeringspeed 0.04
steerinertia 120
minsteer 0.3
maxsteer 0.36
steering_deadzone 0.033
steeringtransfer 0.023
steeringtransferinertia 280
suspension_pitch 3
suspension_pitch_limit 0.06
suspension_roll 30
suspension_roll_limit 0.3
sticky_collisions 0

ad_min_dstep 0.01
ad_max_dstep 0.06
ad_min_speedswitch 2
ad_maxspeed_reductor 0.5

car physics variables

  • maxspeed - top travel speed of car.
  • acceleration - increase of speed with respect to time.
  • inertia - minimum speed before car will move from a stationary state.
  • drag - loss in speed with respect to time.
  • steeringspeed - how fast the wheels turn.
  • steerinertia - how much of the max steering angle is lost as the car increases in speed (crude steering loss).
  • minsteer - minimum steering angle as scalar (1 = 180 degree) attainable after steering loss caused by steeringintertia.
  • maxsteer - maximum steering angle as scalar (1 = 180 degree) attainable at minimal speeds.
  • steering_deadzone - minimum angle of steering considered the deadzone or cutoff, within this angle the steering angle will always be forced to zero.
  • steeringtransfer - how much the wheel rotation angle translates into rotation of the body the wheels are connected to (the car).
  • steeringtransferinertia - how much the steeringtransfer reduces as the car speed increases, this is related to steerinertia to give the crude effect of traction loss of the front tires as speed increases and the inability to force the wheels into a wider angle at higher speeds.
  • suspension_pitch - suspension pitch increment scalar
  • suspension_pitch_limit - max & min pitch limit
  • suspension_roll - suspension roll increment scalar
  • suspension_roll_limit - max & min roll limit
  • sticky_collisions - 0 = bouncy collisions, 1 = sticky collisions

auto drive variables

  • ad_min_dstep - minimum delta-distance from the porygon that can trigger a change in steering direction. The delta-distance is the amount of change in the distance since the last update.
  • ad_max_dstep - maximum delta-distance from the porygon, once this is set any distance above this limit will trigger a change in steering direction.
  • ad_min_speedswitch - minimum distance from the porygon before the speed of the car begins to linearly reduce as it approaches the porygon.
  • ad_maxspeed_reductor - the rate at which the speed reduces as the car approaches the porygon with respect to ad_min_speedswitch.
