[−][src]Struct gdnative::api::GrooveJoint2D
core class GrooveJoint2D
inherits Joint2D
(unsafe).
Official documentation
See the documentation of this class in the Godot engine's official documentation.
Memory management
Non reference counted objects such as the ones of this type are usually owned by the engine.
GrooveJoint2D
is a reference-only type. Persistent references can
only exist in the unsafe Ref<GrooveJoint2D>
form.
In the cases where Rust code owns an object of this type, for example if the object was just
created on the Rust side and not passed to the engine yet, ownership should be either given
to the engine or the object must be manually destroyed using Ref::free
, or Ref::queue_free
if it is a Node
.

Safety
All types in the Godot API have "interior mutability" in Rust parlance.
To enforce that the official thread-safety guidelines are
followed, the typestate pattern is used in the Ref
and TRef
smart pointers,
and the Instance
API. The typestate Access
in these types tracks whether the
access is unique, shared, or exclusive to the current thread. For more information,
see the type-level documentation on Ref
.
Implementations
impl GrooveJoint2D
[src]
pub fn new() -> Ref<GrooveJoint2D, Unique>
[src]
Creates a new instance of this object.
Because this type is not reference counted, the lifetime of the returned object is not automatically managed.
Immediately after creation, the object is owned by the caller, and can be
passed to the engine (in which case the engine will be responsible for
destroying the object) or destroyed manually using Ref::free
, or preferably
Ref::queue_free
if it is a Node
.
pub fn initial_offset(&self) -> f64
[src]
The body B's initial anchor position defined by the joint's origin and a local offset [member initial_offset] along the joint's Y axis (along the groove).
pub fn length(&self) -> f64
[src]
The groove's length. The groove is from the joint's origin towards [member length] along the joint's local Y axis.
pub fn set_initial_offset(&self, offset: f64)
[src]
The body B's initial anchor position defined by the joint's origin and a local offset [member initial_offset] along the joint's Y axis (along the groove).
pub fn set_length(&self, length: f64)
[src]
The groove's length. The groove is from the joint's origin towards [member length] along the joint's local Y axis.
Methods from Deref<Target = Joint2D>
pub fn bias(&self) -> f64
[src]
When [member node_a] and [member node_b] move in different directions the [code]bias[/code] controls how fast the joint pulls them back to their original position. The lower the [code]bias[/code] the more the two bodies can pull on the joint.
pub fn exclude_nodes_from_collision(&self) -> bool
[src]
If [code]true[/code], [member node_a] and [member node_b] can not collide.
pub fn node_a(&self) -> NodePath
[src]
The first body attached to the joint. Must derive from [PhysicsBody2D].
pub fn node_b(&self) -> NodePath
[src]
The second body attached to the joint. Must derive from [PhysicsBody2D].
pub fn set_bias(&self, bias: f64)
[src]
When [member node_a] and [member node_b] move in different directions the [code]bias[/code] controls how fast the joint pulls them back to their original position. The lower the [code]bias[/code] the more the two bodies can pull on the joint.
pub fn set_exclude_nodes_from_collision(&self, enable: bool)
[src]
If [code]true[/code], [member node_a] and [member node_b] can not collide.
pub fn set_node_a(&self, node: impl Into<NodePath>)
[src]
The first body attached to the joint. Must derive from [PhysicsBody2D].
pub fn set_node_b(&self, node: impl Into<NodePath>)
[src]
The second body attached to the joint. Must derive from [PhysicsBody2D].
