Struct MapLayer 

pub struct MapLayer {
    pub tilemap: Tilemap,
    pub visible: bool,
    pub opacity: f32,
    pub scroll_factor: (f32, f32),
    pub blend_mode: BlendMode,
    pub z_index: i32,
    pub no_animation: bool,
    pub level: i32,
}

A single layer in the map rendering stack.

Each layer owns a Tilemap and carries display properties that control how it is positioned and blended relative to other layers.

Fields

tilemap: Tilemap

The tilemap data for this layer.

visible: bool

Whether this layer should be drawn. Invisible layers are skipped entirely during compositing.

opacity: f32

Global opacity: 0.0 = fully transparent, 1.0 = fully opaque.

scroll_factor: (f32, f32)

Parallax scroll factor.

(1.0, 1.0) means the layer scrolls at the same rate as the camera. (0.5, 0.5) means the layer scrolls at half the camera speed (distant background), and (2.0, 2.0) means it scrolls faster (foreground).

blend_mode: BlendMode

How this layer blends with layers rendered below it.

z_index: i32

Sort order. Lower values are rendered first (behind).

no_animation: bool

When true, the layer’s content does not animate frame-to-frame. Renderers may cache pre-rendered tiles for performance.

level: i32

Elevation level this layer belongs to (0 = ground, the default). Multi-level maps split rendering at the player’s elevation: layers with level <= player_elevation render below sprites, layers above render over them.

Implementations

impl MapLayer

pub fn new(tilemap: Tilemap, z_index: i32) -> Self

Create a new layer with sensible defaults.

• tilemap – the tile data for this layer.
• z_index – render order (lower = behind).

Trait Implementations

impl Clone for MapLayer

fn clone(&self) -> MapLayer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MapLayer

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

Formats the value using the given formatter.
