A [Camera3D] that includes collision. This node extends [Camera3D] to add collisions with [Area3D] and/or [PhysicsBody3D] nodes. The camera cannot move through colliding objects. Adds a collision exception so the camera does not collide with the specified node. Adds a collision exception so the camera does not collide with the specified [RID]. Removes all collision exceptions. Returns the distance the camera has been offset due to a collision. Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [code]layer_number[/code] between 1 and 32. Removes a collision exception with the specified node. Removes a collision exception with the specified [RID]. Based on [code]value[/code], enables or disables the specified layer in the [member collision_mask], given a [code]layer_number[/code] between 1 and 32. If [code]true[/code], the camera stops on contact with [Area3D]s. If [code]true[/code], the camera stops on contact with [PhysicsBody3D]s. The camera's collision mask. Only objects in at least one collision layer matching the mask will be detected. 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 camera's collision margin. The camera can't get closer than this distance to a colliding object. The camera's process callback. See [enum ClipProcessCallback]. The camera updates with the [code]_physics_process[/code] callback. The camera updates with the [code]_process[/code] callback.
