  • SPACE_PARAM_CONTACT_MAX_SEPARATION = 1 --- Constant to set/get the maximum distance a shape can be from another before they are considered separated.
  • SPACE_PARAM_BODY_MAX_ALLOWED_PENETRATION = 2 --- Constant to set/get the maximum distance a shape can penetrate another shape before it is considered a collision.
  • SPACE_PARAM_BODY_LINEAR_VELOCITY_SLEEP_THRESHOLD = 3 --- Constant to set/get the threshold linear velocity of activity. A body marked as potentially inactive for both linear and angular velocity will be put to sleep after the time given.
  • SPACE_PARAM_BODY_ANGULAR_VELOCITY_SLEEP_THRESHOLD = 4 --- Constant to set/get the threshold angular velocity of activity. A body marked as potentially inactive for both linear and angular velocity will be put to sleep after the time given.
  • SPACE_PARAM_BODY_TIME_TO_SLEEP = 5 --- Constant to set/get the maximum time of activity. A body marked as potentially inactive for both linear and angular velocity will be put to sleep after this time.
  • SPACE_PARAM_CONSTRAINT_DEFAULT_BIAS = 6 --- Constant to set/get the default solver bias for all physics constraints. A solver bias is a factor controlling how much two objects "rebound", after violating a constraint, to avoid leaving them in that state because of numerical imprecision.
  • SPACE_PARAM_TEST_MOTION_MIN_CONTACT_DEPTH = 7

enum ShapeType:

  • SHAPE_LINE = 0 --- This is the constant for creating line shapes. A line shape is an infinite line with an origin point, and a normal. Thus, it can be used for front/behind checks.

  • AREA_SPACE_OVERRIDE_COMBINE_REPLACE = 2 --- This area adds its gravity/damp values to whatever has been calculated so far. Then stops taking into account the rest of the areas, even the default one.
  • AREA_SPACE_OVERRIDE_REPLACE = 3 --- This area replaces any gravity/damp, even the default one, and stops taking into account the rest of the areas.
  • AREA_SPACE_OVERRIDE_REPLACE_COMBINE = 4 --- This area replaces any gravity/damp calculated so far, but keeps calculating the rest of the areas, down to the default one.

  • DAMPED_STRING_DAMPING = 2 --- Sets the damping ratio of the spring joint. A value of 0 indicates an undamped spring, while 1 causes the system to reach equilibrium as fast as possible (critical damping).

enum CCDMode:

  • CCD_MODE_DISABLED = 0 --- Disables continuous collision detection. This is the fastest way to detect body collisions, but can miss small, fast-moving objects.
  • CCD_MODE_CAST_RAY = 1 --- Enables continuous collision detection by raycasting. It is faster than shapecasting, but less precise.
  • CCD_MODE_CAST_SHAPE = 2 --- Enables continuous collision detection by shapecasting. It is the slowest CCD method, and the most precise.
