Adds the PhysicsBody object with the given RID to the list of PhysicsBody objects excluded from the collision check.
Clears the list of PhysicsBody objects excluded from the collision check.
Returns the spring arm's current length.
Removes the given RID from the list of PhysicsBody objects excluded from the collision check.
The layers against which the collision check shall be done. See url=https://docs.godotengine.org/en/3.3/tutorials/physics/physics_introduction.html#collision-layers-and-masksCollision layers and masks/url in the documentation for more information.
When the collision check is made, a candidate length for the SpringArm is given. The margin is then subtracted to this length and the translation is applied to the child objects of the SpringArm. This margin is useful for when the SpringArm has a Camera as a child node: without the margin, the Camera would be placed on the exact point of collision, while with the margin the Camera would be placed close to the point of collision.
The maximum extent of the SpringArm. This is used as a length for both the ray and the shape cast used internally to calculate the desired position of the SpringArm's child nodes. To know more about how to perform a shape cast or a ray cast, please consult the PhysicsDirectSpaceState documentation.
Construct a new instance of SpringArm. Note: use memnew!SpringArm instead.
A helper node, mostly used in 3rd person cameras.
The SpringArm node is a node that casts a ray (or collision shape) along its z axis and moves all its direct children to the collision point, minus a margin. The most common use case for this is to make a 3rd person camera that reacts to collisions in the environment. The SpringArm will either cast a ray, or if a shape is given, it will cast the shape in the direction of its z axis. If you use the SpringArm as a camera controller for your player, you might need to exclude the player's collider from the SpringArm's collision check.
