Struct riddle_renderer_wgpu::wgpu_ext::WGPUSpriteRenderTarget

pub struct WGPUSpriteRenderTarget<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))?;

let mut target_ctx = target.begin_render()?;
target_ctx.clear(Color::BLUE)?;
target_ctx.present()?;

let mut render_ctx = renderer.begin_render()?;
render_ctx.clear(Color::GREEN)?;
target.sprite().render_at(&mut render_ctx, vec2(0.0, 0.0))?;
render_ctx.present()?;

Implementations

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

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

Create a new render target with the specified dimensions

pub fn begin_render(&self) -> Result<impl RenderContext + '_, RendererError>

Get a render context for the current swap chain frame.

Example

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

let mut target_ctx = target.begin_render()?;
target_ctx.clear(Color::RED);
target_ctx.present();

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

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