The physics layer(s) the query will take into account (as a bitmask). See [url=https://docs.godotengine.org/en/latest/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information.
The [Shape2D] that will be used for collision/intersection queries. This stores the actual reference which avoids the shape to be released while being used for queries, so always prefer using this over [member shape_rid].
The queried shape's [RID] that will be used for collision/intersection queries. Use this over [member shape] if you want to optimize for performance using the Servers API:
[codeblock]
var shape_rid = PhysicsServer2D.circle_shape_create()
var radius = 64
PhysicsServer2D.shape_set_data(shape_rid, radius)
var params = PhysicsShapeQueryParameters2D.new()
params.shape_rid = shape_rid
# Execute physics queries here...
# Release the shape when done with physics queries.
