<brief_description>
|
|
Node for physics collision sweep and immediate overlap queries. 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>
|
|
Updates the collision information for the shape. Use this method to update the collision information immediately instead of waiting for the next [code]_physics_process[/code] call, for example if the shape or its parent has changed state.
|
|
[b]Note:[/b] [code]enabled == true[/code] is not required for this to work.
