<brief_description>
Node for physics collision sweep and immediate overlap queries. Similar to the [RayCast2D] node.
A 2D shape that sweeps a region of space to detect [CollisionObject2D]s.

<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 it's usually used to detect the first collision.
[b]Note:[/b] shape casting is more computationally expensive compared to ray casting.
Shape casting allows to detect collision objects by sweeping its [member shape] along the cast direction determined by [member target_position]. This is similar to [RayCast2D], but it allows for sweeping a region of space, rather than just a straight line. [ShapeCast2D] can detect multiple collision objects. It is useful for things like wide laser beams or snapping a simple shape to a floor.
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 physics frame. This helps to overcome some limitations of [Area2D] when used as an instantaneous detection area, as collision information isn't immediately available to it.
