Query the closest object intersecting a ray.
|
|
</brief_description>
|
|
<description>
|
|
A RayCast represents a line from its origin to its destination position, [code]cast_to[/code]. It is used to query the 2D space in order to find the closest object along the path of the ray.
|
|
RayCast2D can ignore some objects by adding them to the exception list via [code]add_exception[/code], by setting proper filtering with collision layers, or by filtering object types with type masks.
|
|
Only enabled raycasts will be able to query the space and report collisions.
|
|
RayCast2D calculates intersection every fixed frame (see [Node]), and the result is cached so it can be used later until the next frame. If multiple queries are required between fixed frames (or during the same frame) use [method force_raycast_update] after adjusting the raycast.

|
|
Updates the collision information for the ray. Use this method to update the collision information immediately instead of waiting for the next [code]_fixed_process[/code] call, for example if the ray or its parent has changed state. Note: [code]enabled == true[/code] is not required for this to work.

|
Returns the closest object the ray is pointing to. Note that this does not consider the length of the ray, so you must also use [method is_colliding] to check if the object returned is actually colliding with the ray.
|
|
Example:
|
|
[codeblock]
|
|
if RayCast2D.is_colliding():
|
|
var collider = RayCast2D.get_collider()
|
|
[/codeblock]
