Enumerations

enum SpaceParameter:

SpaceParameter SPACE_PARAM_CONTACT_RECYCLE_RADIUS = 0

Constant to set/get the maximum distance a pair of bodies has to move before their collision status has to be recalculated.

SpaceParameter SPACE_PARAM_CONTACT_MAX_SEPARATION = 1

Constant to set/get the maximum distance a shape can be from another before they are considered separated and the contact is discarded.

SpaceParameter SPACE_PARAM_CONTACT_MAX_ALLOWED_PENETRATION = 2

Constant to set/get the maximum distance a shape can penetrate another shape before it is considered a collision.

SpaceParameter SPACE_PARAM_CONTACT_DEFAULT_BIAS = 3

Constant to set/get the default solver bias for all physics contacts. A solver bias is a factor controlling how much two objects "rebound", after overlapping, to avoid leaving them in that state because of numerical imprecision.

SpaceParameter SPACE_PARAM_BODY_LINEAR_VELOCITY_SLEEP_THRESHOLD = 4

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.

SpaceParameter SPACE_PARAM_BODY_ANGULAR_VELOCITY_SLEEP_THRESHOLD = 5

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.

SpaceParameter SPACE_PARAM_BODY_TIME_TO_SLEEP = 6

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.

SpaceParameter SPACE_PARAM_CONSTRAINT_DEFAULT_BIAS = 7

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.

SpaceParameter SPACE_PARAM_SOLVER_ITERATIONS = 8

Constant to set/get the number of solver iterations for all contacts and constraints. The greater the number of iterations, the more accurate the collisions will be. However, a greater number of iterations requires more CPU power, which can decrease performance.


enum ShapeType:

ShapeType SHAPE_WORLD_BOUNDARY = 0

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

ShapeType SHAPE_SEPARATION_RAY = 1

This is the constant for creating separation ray shapes. A separation ray is defined by a length and separates itself from what is touching its far endpoint. Useful for character controllers.

ShapeType SHAPE_SEGMENT = 2

This is the constant for creating segment shapes. A segment shape is a finite line from a point A to a point B. It can be checked for intersections.

ShapeType SHAPE_CIRCLE = 3

This is the constant for creating circle shapes. A circle shape only has a radius. It can be used for intersections and inside/outside checks.

ShapeType SHAPE_RECTANGLE = 4

This is the constant for creating rectangle shapes. A rectangle shape is defined by a width and a height. It can be used for intersections and inside/outside checks.

ShapeType SHAPE_CAPSULE = 5

This is the constant for creating capsule shapes. A capsule shape is defined by a radius and a length. It can be used for intersections and inside/outside checks.

ShapeType SHAPE_CONVEX_POLYGON = 6

This is the constant for creating convex polygon shapes. A polygon is defined by a list of points. It can be used for intersections and inside/outside checks. Unlike the CollisionPolygon2D.polygon property, polygons modified with shape_set_data do not verify that the points supplied form is a convex polygon.

ShapeType SHAPE_CONCAVE_POLYGON = 7

This is the constant for creating concave polygon shapes. A polygon is defined by a list of points. It can be used for intersections checks, but not for inside/outside checks.

ShapeType SHAPE_CUSTOM = 8

This constant is used internally by the engine. Any attempt to create this kind of shape results in an error.


enum AreaParameter:

AreaParameter AREA_PARAM_GRAVITY_OVERRIDE_MODE = 0

Constant to set/get gravity override mode in an area. See AreaSpaceOverrideMode for possible values.

AreaParameter AREA_PARAM_GRAVITY = 1

Constant to set/get gravity strength in an area.

AreaParameter AREA_PARAM_GRAVITY_VECTOR = 2

Constant to set/get gravity vector/center in an area.

AreaParameter AREA_PARAM_GRAVITY_IS_POINT = 3

Constant to set/get whether the gravity vector of an area is a direction, or a center point.

AreaParameter AREA_PARAM_GRAVITY_DISTANCE_SCALE = 4

Constant to set/get the falloff factor for point gravity of an area. The greater this value is, the faster the strength of gravity decreases with the square of distance.

AreaParameter AREA_PARAM_GRAVITY_POINT_ATTENUATION = 5

This constant was used to set/get the falloff factor for point gravity. It has been superseded by AREA_PARAM_GRAVITY_DISTANCE_SCALE.

AreaParameter AREA_PARAM_LINEAR_DAMP_OVERRIDE_MODE = 6

Constant to set/get linear damping override mode in an area. See AreaSpaceOverrideMode for possible values.

AreaParameter AREA_PARAM_LINEAR_DAMP = 7

Constant to set/get the linear damping factor of an area.

Constant to set/get angular damping override mode in an area. See AreaSpaceOverrideMode for possible values.

AreaParameter AREA_PARAM_ANGULAR_DAMP = 9

Constant to set/get the angular damping factor of an area.

AreaParameter AREA_PARAM_PRIORITY = 10

Constant to set/get the priority (order of processing) of an area.


enum AreaSpaceOverrideMode:

AreaSpaceOverrideMode AREA_SPACE_OVERRIDE_DISABLED = 0

This area does not affect gravity/damp. These are generally areas that exist only to detect collisions, and objects entering or exiting them.

AreaSpaceOverrideMode AREA_SPACE_OVERRIDE_COMBINE = 1

This area adds its gravity/damp values to whatever has been calculated so far. This way, many overlapping areas can combine their physics to make interesting effects.

AreaSpaceOverrideMode 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.

AreaSpaceOverrideMode 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.

AreaSpaceOverrideMode 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.


enum BodyMode:

BodyMode BODY_MODE_STATIC = 0

Constant for static bodies. In this mode, a body can be only moved by user code and doesn't collide with other bodies along its path when moved.

BodyMode BODY_MODE_KINEMATIC = 1

Constant for kinematic bodies. In this mode, a body can be only moved by user code and collides with other bodies along its path.

BodyMode BODY_MODE_RIGID = 2

Constant for rigid bodies. In this mode, a body can be pushed by other bodies and has forces applied.

BodyMode BODY_MODE_RIGID_LINEAR = 3

Constant for linear rigid bodies. In this mode, a body can not rotate, and only its linear velocity is affected by external forces.


enum BodyParameter:

BodyParameter BODY_PARAM_BOUNCE = 0

The body's damping value is added to any value set in areas or the default value.

BodyDampMode BODY_DAMP_MODE_REPLACE = 1

The body's damping value replaces any value set in areas or the default value.
