Same as what is already done for shape queries, applied to point and ray queries. Easier to document and more flexible to add more parameters. Also expose intersect_point method to script in 3D. Remove intersect_point_on_canvas in 2D, replaced with a parameter.

Checks how far a [Shape2D] can move without colliding. All the parameters for the query, including the shape and the motion, are supplied through a [PhysicsShapeQueryParameters2D] 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 [Shape2D]s that the shape is already colliding with e.g. inside of, will be ignored. Use [method collide_shape] to determine the [Shape2D]s that the shape is already colliding with.

Checks the intersections of a shape, given through a [PhysicsShapeQueryParameters2D] 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 [PhysicsShapeQueryParameters2D] object, second one is in the collided shape from the physics space.

Checks the intersections of a shape, given through a [PhysicsShapeQueryParameters2D] object, against the space. If it collides with more than one shape, the nearest one is selected. 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. 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 [Vector2]. If the object is an [Area2D], the result is [code](0, 0)[/code].
|
|
[code]normal[/code]: The object's surface normal at the intersection point.
|
|
[code]point[/code]: The intersection point.
|
|
[code]rid[/code]: The intersecting object's [RID].
|
|
[code]shape[/code]: The shape index of the colliding shape.

Checks whether a point is inside any solid shape. Position and other parameters are defined through [PhysicsPointQueryParameters2D]. 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 [code]max_results[/code] parameter, to reduce the processing time.
|
|
[b]Note:[/b] [ConcavePolygonShape2D]s and [CollisionPolygon2D]s in [code]Segments[/code] build mode are not solid shapes. Therefore, they will not be detected.

Intersects a ray in a given space. Ray position and other parameters are defined through [PhysicsRayQueryParameters2D]. 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.
|
|
[code]position[/code]: The intersection point.
|
|
[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.
