Module overlay_maps 

The side tables the overlay builders take alongside the components they draw.

A text label and a sprite are both authored as a component plus per-asset state the component does not carry: the scissor rectangle a screen imposes on it, the layer it draws in, the atlas slot its texture streamed into. The engine assembles these once per frame and hands the same tables to every builder, so they are named once here.

Type Aliases

ClipRects

Scissor rectangle per overlay asset, [x, y, width, height] in the reference canvas the sprite was authored in. An asset absent from the table is unclipped.

OverlayLayers

Draw layer per overlay asset. An asset absent from the table is layer 0.

TextureSlots

Slot in the backend’s atlas pool per streamed texture. A textured sprite whose texture is absent falls back to a solid fill.
