Struct crystal_engine::ModelHandle

pub struct ModelHandle { /* fields omitted */ }

A handle to the model that was loaded. This can be used to move the model around in the world.

When this handle is dropped, the model will disappear from the world on the next tick.

When this handle is cloned, a second model will appear in the world. Both models can be controlled independently.

Implementations

impl ModelHandle

pub fn position(&self) -> Vector3<f32>

Get the current position of the handle. This is short for self.read(|d| d.position)

pub fn rotation(&self) -> Euler<Rad<f32>>

Get the current rotation of the handle. This is short for self.read(|d| d.rotation)

pub fn scale(&self) -> f32

Get the current scale of the handle. This is short for self.read(|d| d.scale)

pub fn read<T>(&self, cb: impl FnOnce(&ModelData) -> T) -> T

Read the data of the model. Optionally returning a value.

let handle: ModelHandle = game_state.new_triangle_model().build();
let scale = handle.read(|d| d.scale);

pub fn modify<T>(&self, cb: impl FnOnce(&mut ModelData) -> T) -> T

Update the model model. Optionally returning a value.

let handle: ModelHandle = game_state.new_triangle_model().build();
handle.modify(|d| d.scale = 0.0 );
