Struct SpriteRenderSystem 

pub struct SpriteRenderSystem<B: RenderBackend> { /* private fields */ }

System for rendering 2D sprites using batched rendering.

This system:

• Queries all entities with Sprite + Transform2D components
• Batches sprites by texture to minimize draw calls
• Sorts by Z-layer for correct rendering order
• Submits draw calls to the GPU backend

Performance

Target: <100 draw calls for 10,000 sprites (100:1 batch ratio)

Implementations

impl<B: RenderBackend> SpriteRenderSystem<B>

pub fn new(backend: B) -> GoudResult<Self>

Creates a new sprite render system with the given backend.

pub fn with_config(backend: B, config: SpriteBatchConfig) -> GoudResult<Self>

Creates a new sprite render system with custom configuration.

pub fn run( &mut self, world: &World, asset_server: &AssetServer, ) -> GoudResult<()>

Runs the sprite rendering system.

This should be called once per frame, after all game logic has been updated.

Arguments

• world - The ECS world containing sprite entities
• asset_server - Asset server for loading textures

Errors

Returns an error if:

• Shader compilation fails
• Buffer allocation fails
• GPU operations fail

pub fn stats(&self) -> (usize, usize, f32)

Gets rendering statistics from the last frame.

Returns (sprite_count, batch_count, batch_ratio) tuple.

pub fn sprite_batch(&self) -> &SpriteBatch<B>

Gets a reference to the underlying sprite batch.

pub fn sprite_batch_mut(&mut self) -> &mut SpriteBatch<B>

Gets a mutable reference to the underlying sprite batch.

Trait Implementations

impl<B: RenderBackend> Debug for SpriteRenderSystem<B>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
