Similar to the [RayCast2D] node. + </brief_description> + <description> + Shape casting allows to detect collision objects by sweeping the [member shape] along the cast direction determined by [member target_position] (useful for things like beam weapons). + Immediate collision overlaps can be done with the [member target_position] set to [code]Vector2(0, 0)[/code] and by calling [method force_shapecast_update] within the same [b]physics_frame[/b]. This also helps to overcome some limitations of [Area2D] when used as a continuous detection area, often requiring waiting a couple of frames before collision information is available to [Area2D] nodes, and when using the signals creates unnecessary complexity. + The node can detect multiple collision objects, but usually the first detected collision + [b]Note:[/b] shape casting is more computationally expensive compared to ray casting. + </description> + <tutorials> + </tutorials> + <methods> + <method name="add_exception"> + <return type="void" /> + <argument index="0" name="node" type="Object" /> + <description> + Adds a collision exception so the shape does not report collisions with the specified node. + </description> + </method> + <method name="add_exception_rid"> + <return type="void" /> + <argument index="0" name="rid" type="RID" /> + <description> + Adds a collision exception so the shape does not report collisions with the specified [RID]. + </description> + </method> + <method name="clear_exceptions"> + <return type="void" /> + <description> + Removes all collision exceptions for this shape. + </description> + </method> + <method name="force_shapecast_update"> + <return type="void" /> + <description> + Updates the collision information for the shape.
