Metroidvania-Style Example

A compact platformer sample with 4bpp tilemap layers (background, platforms, decorative tiles), StaticTilemapLayerCache for the ESP32 fast path when available, and a KinematicActor-based player with climbing and jump rules tailored to the sample map.

Requires PIXELROOT32_ENABLE_4BPP_SPRITES — the scene is guarded in src/MetroidvaniaScene.h.

Requirements (build flags)

• PIXELROOT32_ENABLE_4BPP_SPRITES
• PIXELROOT32_ENABLE_2BPP_SPRITES (enabled alongside 4bpp in this example’s platformio.ini)
• PIXELROOT32_ENABLE_SCENE_ARENA

See platformio.ini for native and esp32dev presets (no esp32cyd environment in this project).

extern pixelroot32::core::Engine engine is wired in the platform headers under src/platforms/.

Platforms

Environment	Display
native	SDL2, 240×240
esp32dev	ST7789 240×240

Controls

Uses GameConstants.h button IDs: Up / Down / Left / Right and Jump (BTN_UP … BTN_JUMP). Map these to your InputManager / GPIO / keyboard mapping for the platform file you use.

How this scene uses the tilemap cache

Like the animated tilemap sample, drawing goes through StaticTilemapLayerCache: allocate for the renderer when layers are ready, draw static groups with camera offsets, and invalidate() when static tile data or relevant animators change. See Animated Tilemap README for the detailed invalidation table and Architecture — static tilemap cache.

Features

• 4bpp tilemaps and layered level data
• StaticTilemapLayerCache snapshot path when the driver exposes a logical framebuffer
• Player actor with gravity, stairs/climb behavior, and map collision
• Scene arena + owned layer entities
