- Document a few more properties and methods - Add more information to many classes - Fix lots of typos and gramar mistakes - Use [code] tags for parameters consistently - Use [b] and [i] tags consistently - Put "Warning:" and "Note:" on their own line to be more visible, and make them always bold - Tweak formatting in code examples to be more readable - Use double quotes consistently - Add more links to third-party technologies

Checks how far the shape can travel toward a point. If the shape can not move, the array will be empty.
|
|
[b]Note:[/b] Both the shape and the motion are supplied through a [Physics2DShapeQueryParameters] object. The method will return an array with two floats between 0 and 1, both representing a fraction of [code]motion[/code]. The first is how far the shape can move without triggering a collision, and the second is the point at which a collision will occur. If no collision is detected, the returned array will be [code][1, 1][/code].

Checks the intersections of a shape, given through a [Physics2DShapeQueryParameters] 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 [Physics2DShapeQueryParameters] 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 Physics2DServer.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 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 Physics2DServer.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 check in, or booleans to determine if the ray should collide with [PhysicsBody]s or [Area]s, respectively.

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 Physics2DServer.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 check in, or booleans to determine if the ray should collide with [PhysicsBody]s or [Area]s, respectively.

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