Struct riddle_renderer_wgpu::SpriteRenderTarget

pub struct SpriteRenderTarget<Device: WGPUDevice> { /* fields omitted */ }

A target which can be both rendered to and referenced as a Sprite for rendering.

Example

let renderer = Renderer::new_from_window(&window)?;

let target = SpriteRenderTarget::new(&renderer, vec2(100, 100))?;

target.render(|target_ctx| {
    target_ctx.clear(Color::BLUE)
})?;

renderer.render(|render_ctx| {
    render_ctx.clear(Color::GREEN)?;
    target.sprite().render_at(render_ctx, vec2(0.0, 0.0))
})?;

Implementations

impl<Device> SpriteRenderTarget<Device> where
    Device: WGPUDevice, 

pub fn new(
    renderer: &Renderer<Device>,
    dimensions: Vector2<u32>
) -> Result<Self, WGPURendererError>

Create a new render target with the specified dimensions

pub fn render<R, F>(&self, f: F) -> Result<R, RendererError> where
    F: FnOnce(&mut BufferedRenderer<Device, &SpriteRenderTarget<Device>>) -> Result<R, RendererError>, 

Get a render context for the current swap chain frame.

Example

let target = SpriteRenderTarget::new(&renderer, vec2(100, 100))?;

target.render(|target_ctx| {
    target_ctx.clear(Color::RED)
})?;

pub fn sprite(&self) -> &Sprite<Device>

Get the sprite which can be used to render the contents of the render target.
