On native/PC you can safely use a higher value; on ESP32, increasing it may affect performance or memory. - -### Option A: Compiler flags (recommended) - -In your project (e.g. in `platformio.ini`), add the defines to `build_flags` for the environment you use: - -```ini -build_flags = - -DMAX_LAYERS=5 - -DMAX_ENTITIES=64 -``` - -The compiler defines `MAX_LAYERS` and `MAX_ENTITIES` before processing any `.cpp` file. Because `Scene.h` uses `#ifndef MAX_LAYERS` / `#ifndef MAX_ENTITIES`, it will not redefine them and your values will be used. - -**Effect:** -- **MAX_LAYERS**: Number of render layers drawn in `Scene::draw()` (layer 0 = background, 1+ = sprite context). Increasing this allows more distinct draw layers (e.g. background, platforms, gameplay, foreground, UI). -- **MAX_ENTITIES**: On Arduino, the capacity of the scene entity queue when constructed with this value. On native (mock queue), the value is ignored (unbounded). - -See also: [Platforms and Drivers](../manual/optimization/platforms_and_drivers.md). - -## Usage Example - -```cpp -#include "core/Scene.h"

Useful for camera/parallax effects. - -**Parameters:** - -- `x` (int): X offset in pixels -- `y` (int): Y offset in pixels - -**Notes:** - -- All subsequent drawing operations are offset by this amount -- Useful for camera scrolling and parallax effects -- Reset to (0, 0) to disable offset - -**Example:** - -```cpp -// Camera scrolling -camera.setPosition(playerX - 64, playerY - 64); -renderer.setDisplayOffset(-camera.getX(), -camera.getY()); -renderer.drawTileMap(background, 0, 0, Color::White); -``` - -### void setDisplaySize(int w, int h) - -Sets the logical display size. - -**Parameters:** - -- `w` (int): Width in pixels -- `h` (int): Height in pixels - -**Notes:** - -- Typically set via `DisplayConfig` during construction -- Use this to change display size at runtime if needed - -### int getXOffset() const - -Gets the current X display offset. - -**Returns:** - -- `int`: X offset in pixels - -### int getYOffset() const - -Gets the current Y display offset. - -**Returns:** - -- `int`: Y offset in pixels - -### void setContrast(uint8_t level) - -Sets the display contrast (brightness). - -**Parameters:** - -- `level` (uint8_t): Contrast level (0-255) - -**Notes:** - -- Platform-specific: may not be supported on all displays -- Higher values = brighter display - -### void setFont(const uint8_t* font) - -Sets the font for text rendering. - -**Parameters:** - -- `font` (const uint8_t*): Pointer to the font data - -**Notes:** - -- Sets the default font for `drawText()` calls without font parameter -- Use font constants like `FONT_5X7` from `Font.h` - -## Usage Example - -```cpp -#include "graphics/Renderer.h" -#include "graphics/DisplayConfig.h" - -void draw(Renderer& renderer) override { - renderer.beginFrame(); - - // Draw background - renderer.drawFilledRectangle(0, 0, 128, 128, Color::Black); - - // Draw sprites - renderer.drawSprite(playerSprite, playerX, playerY, Color::White); - renderer.drawSprite(enemySprite, enemyX, enemyY, Color::Red); - - // Draw UI - renderer.drawText("Score: 100", 10, 10, Color::White, 1); - renderer.drawTextCentered("Game Over", 64, Color::Yellow, 2); - - renderer.endFrame(); -} -``` - -## Performance Considerations - -- **Integer-only math**: All operations use integer arithmetic for ESP32 efficiency -- **Sprite storage**: Store sprite data in flash (const/constexpr) for best performance -- **Batch operations**: Group similar draw calls together -- **Tilemaps**: Draws a full tilemap with automatic viewport culling. For 2bpp/4bpp, supports optional per-cell palette slots via `paletteIndices` (see [Color Palettes](../../manual/advanced_graphics/color_palettes.md) — Background palette slot bank). -- **Sprites 2bpp/4bpp**: Optimised for ESP32 (IRAM + 16-bit access). - -## ESP32 Considerations - -- **Memory**: Sprite data should be in flash, not RAM -- **Frame rate**: Limit draw calls per frame for

These are guarded with `#ifndef`, so you can override them from your project without modifying the engine. + +> **Note:** The default of 3 for `MAX_LAYERS` is due to ESP32 platform constraints (memory and draw-loop cost). On native/PC you can safely use a higher value; on ESP32, increasing it may affect performance or memory. + +**Compiler flags (recommended)** + +In your project (e.g. in `platformio.ini`), add the defines to `build_flags` for the environment you use: + +```ini +build_flags = + -DMAX_LAYERS=5 + -DMAX_ENTITIES=64 +``` + +The compiler defines `MAX_LAYERS` and `MAX_ENTITIES` before processing any `.cpp` file. Because `Scene.h` uses `#ifndef MAX_LAYERS` / `#ifndef MAX_ENTITIES`, it will not redefine them and your values will be used. This affects how many render layers are drawn (see `Scene::draw`) and, on Arduino, the capacity of the scene entity queue when constructed with `MAX_ENTITIES`. + +--- + +### SceneManager + +**Inherits:** None + +Manages the stack of active scenes.

The cache key is the pair (tile palette pointer, background palette pointer). When `paletteIndices` is used, the LUT is rebuilt only when either the tile’s palette or the cell’s background palette slot changes (`lastTilePalettePtr` / `lastBackgroundPalettePtr`), minimizing redundant work. +- **Viewport Culling**: All tilemap rendering functions automatically skip tiles that are outside the current screen boundaries. + +- **`void setDisplaySize(int w, int h)`** + Sets the logical display size. + +- **`void setDisplayOffset(int x, int y)`** + Sets a global offset for all drawing operations. + +- **`void setContrast(uint8_t level)`** + Sets the display contrast/brightness (0-255). + +--- + +### Font System + +The engine includes a native bitmap font system that uses 1bpp sprites to render text, ensuring pixel-perfect consistency between PC (SDL2) and ESP32 platforms. + +#### Font Structure + +**Type:** `struct Font` + +Represents a bitmap font containing glyph sprites for ASCII characters. + +**Members:** + +- **`const Sprite* glyphs`**: Array of sprite structures, one per character. +- **`uint8_t firstChar`**: First character code in the font (e.g., 32 for space). +- **`uint8_t lastChar`**: Last character code in the font (e.g., 126 for tilde). +- **`uint8_t glyphWidth`**: Fixed width of each glyph in pixels. +- **`uint8_t glyphHeight`**: Fixed height of each glyph in pixels. +- **`uint8_t spacing`**: Horizontal spacing between characters in pixels. +- **`uint8_t lineHeight`**: Vertical line height (includes spacing between lines). + +**Example:** + +```cpp +#include +#include + +// The built-in 5x7 font is available as FONT_5X7 +const Font* myFont = &pixelroot32::graphics::FONT_5X7; +``` + +#### FontManager + +**Type:** `class FontManager` + +Static utility class for managing fonts and calculating text dimensions. + +**Static Methods:** + +- **`static void setDefaultFont(const Font* font)`** + Sets the default font used by `Renderer::drawText()` when no font is explicitly provided.

Use `initRuntimeMask()`, `isTileActive()`, `setTileActive()`; size is `(width * height + 7) / 8` bytes. + +- **`const uint8_t* paletteIndices`** + Optional per-cell background palette index (for 2bpp/4bpp multi-palette tilemaps only). If `nullptr`, all cells use the default background palette (slot 0). If non-null, array size must be `width * height`; each byte uses bits 0–2 for the palette slot (0–7), bits 3–7 reserved for future use. Use with `setBackgroundPaletteSlot` / `setBackgroundCustomPaletteSlot` to assign palettes to slots. Typically filled by the editor or export tools; can be stored in PROGMEM. + +- **`TileAnimationManager* animManager`** + Optional pointer to a `TileAnimationManager` for tile animations. If non-null, the renderer will resolve animated tile frames automatically. Set to `nullptr` (default) to disable animations with zero overhead.

For independent animations, use different tile indices. + +2. **Sequential Frames**: Frames must be sequential in the tileset (e.g., tiles 42, 43, 44, 45). Non-sequential frame sequences are not supported in v1.0. + +3. **Global Timing**: All animations advance together by default. Per-animation timing requires multiple managers or conditional `step()` calls. + +4. **Static Tilemap Data**: Tilemap indices never change. Animation is purely a rendering transformation. + +5. **Maximum Animations**: Limited by `uint8_t` (255), but practical limit is ~16-32 for memory reasons. + +--- + +### Compatibility + +| Feature | 1bpp Tilemap | 2bpp Tilemap | 4bpp Tilemap | +|---------|--------------|--------------|--------------| +| Basic Animation | ✅ | ✅ | ✅ | +| Per-Cell Palette | ❌ | ✅ | ✅ | +| Runtime Mask | ✅ | ✅ | ✅ | +| Viewport Culling | ✅ | ✅ | ✅ | + +**Note:** Tile animations work with all tilemap types and are compatible with existing features (runtime mask, per-cell palettes, viewport culling). + +--- + +### Tile Attribute System + +The tile attribute system provides runtime access to custom metadata attached to tiles in tilemaps.
