For the time being we don't support writing a description for those, preferring having all details in the method's description. Using self-closing tags saves half the lines, and prevents contributors from thinking that they should write the argument or return documentation there.

A helper node, mostly used in 3rd person cameras.

|
The SpringArm3D 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 SpringArm3D 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 SpringArm3D as a camera controller for your player, you might need to exclude the player's collider from the SpringArm3D's collision check.

The layers against which the collision check shall be done. 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.

<member name="margin" type="float" setter="set_margin" getter="get_margin" default="0.01">
|
|
When the collision check is made, a candidate length for the SpringArm3D is given.
|
|
The margin is then subtracted to this length and the translation is applied to the child objects of the SpringArm3D.
|
|
This margin is useful for when the SpringArm3D has a [Camera3D] as a child node: without the margin, the [Camera3D] would be placed on the exact point of collision, while with the margin the [Camera3D] would be placed close to the point of collision.

|
|
<member name="shape" type="Shape3D" setter="set_shape" getter="get_shape">
|
|
The [Shape3D] to use for the SpringArm3D.
|
|
When the shape is set, the SpringArm3D will cast the [Shape3D] on its z axis instead of performing a ray cast.
|
|
</member>
|
|
<member name="spring_length" type="float" setter="set_length" getter="get_length" default="1.0">
|
|
The maximum extent of the SpringArm3D. This is used as a length for both the ray and the shape cast used internally to calculate the desired position of the SpringArm3D's child nodes.
|
|
To know more about how to perform a shape cast or a ray cast, please consult the [PhysicsDirectSpaceState3D] documentation.
