Base node for collision objects. CollisionObject3D is the base class for physics objects. It can hold any number of collision [Shape3D]s. Each shape must be assigned to a [i]shape owner[/i]. The CollisionObject3D can have any number of shape owners. Shape owners are not nodes and do not appear in the editor, but are accessible through code using the [code]shape_owner_*[/code] methods. Receives unhandled [InputEvent]s. [param position] is the location in world space of the mouse pointer on the surface of the shape with index [param shape_idx] and [param normal] is the normal vector of the surface at that point. Connect to the [signal input_event] signal to easily pick up these events. [b]Note:[/b] [method _input_event] requires [member input_ray_pickable] to be [code]true[/code] and at least one [member collision_layer] bit to be set. Creates a new shape owner for the given object. Returns [code]owner_id[/code] of the new owner for future reference. Returns whether or not the specified layer of the [member collision_layer] is enabled, given a [param layer_number] between 1 and 32. Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [param layer_number] between 1 and 32. Returns the object's [RID]. Returns an [Array] of [code]owner_id[/code] identifiers. You can use these ids in other methods that take [code]owner_id[/code] as an argument. If [code]true[/code], the shape owner and its shapes are disabled. Removes the given shape owner. Based on [param value], enables or disables the specified layer in the [member collision_layer], given a [param layer_number] between 1 and 32. Based on [param value], enables or disables the specified layer in the [member collision_mask], given a [param layer_number] between 1 and 32. Returns the [code]owner_id[/code] of the given shape. Adds a [Shape3D] to the shape owner. Removes all shapes from the shape owner. Returns the parent object of the given shape owner. Returns the [Shape3D] with the given id from the given shape owner. Returns the number of shapes the given shape owner contains. Returns the child index of the [Shape3D] with the given id from the given shape owner. Returns the shape owner's [Transform3D]. Removes a shape from the given shape owner. If [code]true[/code], disables the given shape owner. Sets the [Transform3D] of the given shape owner. The physics layers this CollisionObject3D [b]is in[/b]. Collision objects can exist in one or more of 32 different layers. See also [member collision_mask]. [b]Note:[/b] Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See [url=$DOCS_URL/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information. The physics layers this CollisionObject3D [b]scans[/b]. Collision objects can scan one or more of 32 different layers. See also [member collision_layer]. [b]Note:[/b] Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See [url=$DOCS_URL/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information. Defines the behavior in physics when [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED]. See [enum DisableMode] for more details about the different modes. If [code]true[/code], the [CollisionObject3D] will continue to receive input events as the mouse is dragged across its shapes. If [code]true[/code], this object is pickable. A pickable object can detect the mouse pointer entering/leaving, and if the mouse is inside it, report input events. Requires at least one [member collision_layer] bit to be set. Emitted when the object receives an unhandled [InputEvent]. [param position] is the location in world space of the mouse pointer on the surface of the shape with index [param shape_idx] and [param normal] is the normal vector of the surface at that point. Emitted when the mouse pointer enters any of this object's shapes. Requires [member input_ray_pickable] to be [code]true[/code] and at least one [member collision_layer] bit to be set. [b]Note:[/b] Due to the lack of continuous collision detection, this signal may not be emitted in the expected order if the mouse moves fast enough and the [CollisionObject2D]'s area is small. This signal may also not be emitted if another [CollisionObject2D] is overlapping the [CollisionObject2D] in question. Emitted when the mouse pointer exits all this object's shapes. Requires [member input_ray_pickable] to be [code]true[/code] and at least one [member collision_layer] bit to be set. [b]Note:[/b] Due to the lack of continuous collision detection, this signal may not be emitted in the expected order if the mouse moves fast enough and the [CollisionObject2D]'s area is small. This signal may also not be emitted if another [CollisionObject2D] is overlapping the [CollisionObject2D] in question. When [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED], remove from the physics simulation to stop all physics interactions with this [CollisionObject3D]. Automatically re-added to the physics simulation when the [Node] is processed again. When [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED], make the body static. Doesn't affect [Area2D]. [PhysicsBody3D] can't be affected by forces or other bodies while static. Automatically set [PhysicsBody3D] back to its original mode when the [Node] is processed again. When [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED], do not affect the physics simulation.
