Struct gdnative_bindings_lily::Polygon2D

pub struct Polygon2D { /* fields omitted */ }

core class Polygon2D inherits Node2D (unsafe).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

Polygon2D is a reference-only type. Persistent references can only exist in the unsafe Ref<Polygon2D> 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.

Class hierarchy

Polygon2D inherits methods from:

• Node2D
• CanvasItem
• Node
• Object

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 Polygon2D

pub fn new() -> Ref<Self, Unique>

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 add_bone(&self, path: impl Into<NodePath>, weights: Float32Array)

Adds a bone with the specified path and weights.

pub fn clear_bones(&self)

Removes all bones from this Polygon2D.

pub fn erase_bone(&self, index: i64)

Removes the specified bone from this Polygon2D.

pub fn antialiased(&self) -> bool

If true, polygon edges will be anti-aliased.

pub fn get_bone_count(&self) -> i64

Returns the number of bones in this Polygon2D.

pub fn get_bone_path(&self, index: i64) -> NodePath

Returns the path to the node associated with the specified bone.

pub fn get_bone_weights(&self, index: i64) -> Float32Array

Returns the height values of the specified bone.

pub fn color(&self) -> Color

The polygon’s fill color. If texture is defined, it will be multiplied by this color. It will also be the default color for vertices not set in vertex_colors.

pub fn internal_vertex_count(&self) -> i64

pub fn invert(&self) -> bool

If true, polygon will be inverted, containing the area outside the defined points and extending to the invert_border.

pub fn invert_border(&self) -> f64

Added padding applied to the bounding box when using invert. Setting this value too small may result in a “Bad Polygon” error.

pub fn offset(&self) -> Vector2

The offset applied to each vertex.

pub fn polygon(&self) -> Vector2Array

Transforms the provided local position into a position in global coordinate space. The input is expected to be local relative to the Node2D it is called on. e.g. Applying this method to the positions of child nodes will correctly transform their positions into the global coordinate space, but applying it to a node’s own position will give an incorrect result, as it will incorporate the node’s own transformation into its global position.

pub fn to_local(&self, global_point: Vector2) -> Vector2

Transforms the provided global position into a position in local coordinate space. The output will be local relative to the Node2D it is called on. e.g. It is appropriate for determining the positions of child nodes, but it is not appropriate for determining its own position relative to its parent.

pub fn translate(&self, offset: Vector2)

Translates the node by the given offset in local coordinates.
