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. + </description> + <tutorials> + </tutorials> + <demos> + </demos> + <methods> + <method name="add_exception"> + <return type="void"> + </return> + <argument index="0" name="node" type="Object"> + </argument> + <description> + Adds a collision exception so the ray does not report collisions with the specified node. + </description> + </method> + <method name="add_exception_rid"> + <return type="void"> + </return> + <argument index="0" name="rid" type="RID"> + </argument> + <description> + Adds a collision exception so the ray does not report collisions with the specified [RID]. + </description> + </method> + <method name="clear_exceptions"> + <return type="void"> + </return> + <description> + Removes all collision exceptions for this ray. + </description> + </method> + <method name="force_raycast_update"> + <return type="void"> + </return> + <description> + Updates the collision information for the ray.
