Layers

CHIPcade features 8 graphical layers, managed by the Graphics Co-Processor. These are perfect for backgrounds, UI, parallax scrolling, and more.

You can access layers using:

    layer[2].width =  800
    layer[R2].height = 600
    layer[2].mode = "centered"
    l[R2].visible = true

Just like registers, you can reference them by index or indirectly through a register.

Default Behavior

All layers default to the screen resolution
Layers are not visible by default — set visible = true to show them
Layers are automatically blended from bottom to top, with layer[0] at the back and layer[7] on top

Each layer supports the following properties:

mode Controls how the layer is positioned on screen.
- "manual" — You control the position using x and y (this is the default).
- "centered" — Automatically centers the layer on the screen (if it has a custom size).
x Horizontal offset of the layer on screen. Only used when mode is set to "manual". Default: 0
y Vertical offset of the layer on screen. Only used when mode is set to "manual". Default: 0
width Sets the width of the layer in pixels. This can be different from the screen size.
height Sets the height of the layer in pixels. Useful for scrolling layers or offscreen buffers.
visible A boolean flag (true or false). Layers are invisible by default — set this to true to render them.

    layer[0].width = 320
    layer[0].height = 256
    layer[0].visible = true

Layers are blended automatically from layer 0 (back) to layer 7 (front).
