- Back to 1-based layer names to make it clearer in editor UI - Layer bit accessors are renamed to layer value and 1-based too - Uniform errors and documentation in render and physics - Fix a few remaining collision_layer used in place of collision_mask

Direct access object to a space in the [PhysicsServer2D]. It's used mainly to do queries against objects and areas residing in a given space.

|
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.

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]metadata[/code]: The intersecting shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method PhysicsServer2D.shape_set_data].
|
|
[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. 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]metadata[/code]: The intersecting shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method PhysicsServer2D.shape_set_data].
|
|
[code]rid[/code]: The intersecting object's [RID].
|
|
[code]shape[/code]: The shape index of the colliding shape.
|
|
Additionally, the method can take an [code]exclude[/code] array of objects or [RID]s that are to be excluded from collisions, a [code]collision_mask[/code] bitmask representing the physics layers to detect, or booleans to determine if the ray should collide with [PhysicsBody2D]s or [Area2D]s, respectively.
|
|
[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. 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]metadata[/code]: The intersecting shape's metadata. This metadata is different from [method Object.get_meta], and is set with [method PhysicsServer2D.shape_set_data].
|
|
[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.
|

Additionally, the method can take an [code]exclude[/code] array of objects or [RID]s that are to be excluded from collisions, a [code]collision_mask[/code] bitmask representing the physics layers to detect, or booleans to determine if the ray should collide with [PhysicsBody2D]s or [Area2D]s, respectively.

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