Shape casting allows to detect collision objects by sweeping its shape along the cast direction determined by target_position. This is similar to RayCast3D, but it allows for sweeping a region of space, rather than just a straight line. ShapeCast3D can detect multiple collision objects. It is useful for things like wide laser beams or snapping a simple shape to a floor.
Immediate collision overlaps can be done with the target_position set to Vector3(0, 0, 0)
and by calling force_shapecast_update() within the same physics frame. This helps to overcome some limitations of Area3D when used as an instantaneous detection area, as collision information isn't immediately available to it.
If true
, collisions with Area3Ds will be reported.
If true
, collisions with PhysicsBody3Ds will be reported.
The shape's collision mask. Only objects in at least one collision layer enabled in the mask will be detected. See Collision layers and masks in the documentation for more information.
Returns the complete collision information from the collision sweep. The data returned is the same as in the PhysicsDirectSpaceState3D.get_rest_info() method.
The custom color to use to draw the shape in the editor and at run-time if Visible Collision Shapes is enabled in the Debug menu. This color will be highlighted at run-time if the ShapeCast3D is colliding with something.
If set to Color(0.0, 0.0, 0.0)
(by default), the color set in ProjectSettings.debug/shapes/collision/shape_color is used.
If true
, collisions will be reported.
If true
, the parent node will be excluded from collision detection.
The collision margin for the shape. A larger margin helps detecting collisions more consistently, at the cost of precision.
The number of intersections can be limited with this parameter, to reduce the processing time.
The shape to be used for collision queries.
The shape's destination point, relative to this node's Node3D.position.
Adds a collision exception so the shape does not report collisions with the specified node.
Adds a collision exception so the shape does not report collisions with the specified RID.
Removes all collision exceptions for this shape.
Updates the collision information for the shape immediately, without waiting for the next _physics_process
call. Use this method, for example, when the shape or its parent has changed state.
Note: Setting enabled to true
is not required for this to work.
Returns the fraction from this cast's origin to its target_position of how far the shape can move without triggering a collision, as a value between 0.0
and 1.0
.
Returns the fraction from this cast's origin to its target_position of how far the shape must move to trigger a collision, as a value between 0.0
and 1.0
.
In ideal conditions this would be the same as get_closest_collision_safe_fraction(), however shape casting is calculated in discrete steps, so the precise point of collision can occur between two calculated positions.
Returns the collided Object of one of the multiple collisions at index
, or null
if no object is intersecting the shape (i.e. is_colliding() returns false
).
Returns the RID of the collided object of one of the multiple collisions at index
.
Returns the shape ID of the colliding shape of one of the multiple collisions at index
, or 0
if no object is intersecting the shape (i.e. is_colliding() returns false
).
The number of collisions detected at the point of impact. Use this to iterate over multiple collisions as provided by get_collider(), get_collider_shape(), get_collision_point(), and get_collision_normal() methods.
Returns whether or not the specified layer of the collision_mask is enabled, given a layer_number
between 1 and 32.
Returns the normal of one of the multiple collisions at index
of the intersecting object.
Returns the collision point of one of the multiple collisions at index
where the shape intersects the colliding object.
Note: This point is in the global coordinate system.
Returns whether any object is intersecting with the shape's vector (considering the vector length).
Removes a collision exception so the shape does report collisions with the specified node.
Removes a collision exception so the shape does report collisions with the specified RID.
Deprecated: Use Resource.changed instead.
This method does nothing.
Based on value
, enables or disables the specified layer in the collision_mask, given a layer_number
between 1 and 32.
