This makes it easier to spot syntax errors when editing the class reference. The schema is referenced locally so validation can still work offline. Each class XML's schema conformance is also checked on GitHub Actions.

|
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, or [code]Vector2(0, 0)[/code] if the ray starts inside the shape and [member PhysicsRayQueryParameters2D.hit_from_inside] is [code]true[/code].
|
|
[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.
