|
Provides direct access to a physics space in the [PhysicsServer3D]. It's used mainly to do queries against objects and areas residing in a given space.
|
|
[b]Note:[/b] This class is not meant to be instantiated directly. Use [member World3D.direct_space_state] to get the world's physics 3D space state.

<return type="PackedFloat32Array" />

<param index="0" name="parameters" type="PhysicsShapeQueryParameters3D" />
|

<description>
|
|
Checks how far a [Shape3D] can move without colliding. All the parameters for the query, including the shape and the motion, are supplied through a [PhysicsShapeQueryParameters3D] 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 [code][1.0, 1.0][/code] will be returned.
|
|
[b]Note:[/b] Any [Shape3D]s that the shape is already colliding with e.g. inside of, will be ignored. Use [method collide_shape] to determine the [Shape3D]s that the shape is already colliding with.

|
Checks the intersections of a shape, given through a [PhysicsShapeQueryParameters3D] object, against the space. The resulting array contains a list of points where the shape intersects another. Like with [method intersect_shape], the number of returned results can be limited to save processing time.
|
|
Returned points are a list of pairs of contact points. For each pair the first one is in the shape passed in [PhysicsShapeQueryParameters3D] object, second one is in the collided shape from the physics space.
|
|
[b]Note:[/b] This method does not take into account the [code]motion[/code] property of the object.

<description>
|
|
Checks the intersections of a shape, given through a [PhysicsShapeQueryParameters3D] 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:
|
|
[code]collider_id[/code]: The colliding object's ID.
|
|
[code]linear_velocity[/code]: The colliding object's velocity [Vector3]. If the object is an [Area3D], the result is [code](0, 0, 0)[/code].
|
|
[code]normal[/code]: The collision normal of the query shape at the intersection point, pointing away from the intersecting object.
|
|
[code]point[/code]: The intersection point.
|
|
[code]rid[/code]: The intersecting object's [RID].
|
|
[code]shape[/code]: The shape index of the colliding shape.
|
|
If the shape did not intersect anything, then an empty dictionary is returned instead.
|
|
[b]Note:[/b] This method does not take into account the [code]motion[/code] property of the object.

|
Checks whether a point is inside any solid shape. Position and other parameters are defined through [PhysicsPointQueryParameters3D]. The shapes the point is inside of are returned in an array containing dictionaries with the following fields:
|
|
[code]collider[/code]: The colliding object.
|
|
[code]collider_id[/code]: The colliding object's ID.
|
|
[code]rid[/code]: The intersecting object's [RID].
|
|
[code]shape[/code]: The shape index of the colliding shape.
|
|
The number of intersections can be limited with the [param max_results] parameter, to reduce the processing time.

|

<description>
|
|
Intersects a ray in a given space. Ray position and other parameters are defined through [PhysicsRayQueryParameters3D]. The returned object is a dictionary with the following fields:
|
|
[code]collider[/code]: The colliding object.
|
|
[code]collider_id[/code]: The colliding object's ID.
|
|
[code]normal[/code]: The object's surface normal at the intersection point, or [code]Vector3(0, 0, 0)[/code] if the ray starts inside the shape and [member PhysicsRayQueryParameters3D.hit_from_inside] is [code]true[/code].
|
|
[code]position[/code]: The intersection point.
|
|
[code]face_index[/code]: The face index at the intersection point.
|
|
[b]Note:[/b] Returns a valid number only if the intersected shape is a [ConcavePolygonShape3D]. Otherwise, [code]-1[/code] is returned.
|
|
[code]rid[/code]: The intersecting object's [RID].
|
|
[code]shape[/code]: The shape index of the colliding shape.
|
|
If the ray did not intersect anything, then an empty dictionary is returned instead.
