Struct MapRenderState 

pub struct MapRenderState {
    pub layers: Vec<MapLayer>,
    pub background_color: (u8, u8, u8, u8),
}

The complete rendering state for a map (all layers).

Fields

layers: Vec<MapLayer>

Ordered stack of map layers. The compositor sorts them by MapLayer::z_index before drawing.

background_color: (u8, u8, u8, u8)

RGBA background colour used to fill the framebuffer before any layer is drawn.

Implementations

impl MapRenderState

pub fn new() -> Self

Create an empty render state with a transparent black background.

pub fn add_layer(&mut self, layer: MapLayer)

Add a layer to the stack.

pub fn visible_layer_count(&self) -> usize

Count how many layers are currently visible.
