Methods

Method Descriptions

• Array cast_motion ( PhysicsShapeQueryParameters shape, Vector3 motion )

Checks how far a Shape can move without colliding. All the parameters for the query, including the shape, are supplied through a PhysicsShapeQueryParameters object.

Returns an array with the safe and unsafe proportions (between 0 and 1) of the motion. The safe proportion is the maximum fraction of the motion that can be made without a collision. The unsafe proportion is the minimum fraction of the distance that must be moved for a collision. If no collision is detected a result of [1.0, 1.0] will be returned.

Note: Any Shapes that the shape is already colliding with e.g. inside of, will be ignored. Use collide_shape to determine the Shapes that the shape is already colliding with.

• Array collide_shape ( PhysicsShapeQueryParameters shape, int max_results=32 )

Checks the intersections of a shape, given through a PhysicsShapeQueryParameters object, against the space. The resulting array contains a list of points where the shape intersects another. Like with intersect_shape, the number of returned results can be limited to save processing time.

• Dictionary get_rest_info ( PhysicsShapeQueryParameters shape )

Checks the intersections of a shape, given through a PhysicsShapeQueryParameters object, against the space. If it collides with more than one shape, the nearest one is selected. The returned object is a dictionary containing the following fields:

collider_id: The colliding object’s ID.

linear_velocity: The colliding object’s velocity Vector3. If the object is an Area, the result is (0, 0, 0).

normal: The object’s surface normal at the intersection point.

point: The intersection point.

rid: The intersecting object’s RID.

shape: The shape index of the colliding shape.

If the shape did not intersect anything, then an empty dictionary is returned instead.

• Dictionary intersect_ray ( Vector3 from, Vector3 to, Array exclude=[ ], int collision_mask=2147483647, bool collide_with_bodies=true, bool collide_with_areas=false )

Intersects a ray in a given space. The returned object is a dictionary with the following fields:

collider: The colliding object.

collider_id: The colliding object’s ID.

normal: The object’s surface normal at the intersection point.

position: The intersection point.

rid: The intersecting object’s RID.

shape: The shape index of the colliding shape.

If the ray did not intersect anything, then an empty dictionary is returned instead.

Additionally, the method can take an exclude array of objects or RIDs that are to be excluded from collisions, a collision_mask bitmask representing the physics layers to check in, or booleans to determine if the ray should collide with PhysicsBodys or Areas, respectively.

• Array intersect_shape ( PhysicsShapeQueryParameters shape, int max_results=32 )

Checks the intersections of a shape, given through a PhysicsShapeQueryParameters object, against the space. The intersected shapes are returned in an array containing dictionaries with the following fields:

collider: The colliding object.

collider_id: The colliding object’s ID.

rid: The intersecting object’s RID.

shape: The shape index of the colliding shape.

The number of intersections can be limited with the max_results parameter, to reduce the processing time.
