TileAnimation
StructSource: TileAnimation.h
Description
Single tile animation definition (compile-time constant).
Defines a sequence of tile indices that form an animation loop. All data stored in PROGMEM/flash to minimize RAM usage.
Memory Layout: 4 bytes total (POD structure)
- baseTileIndex: First tile in animation sequence (0-255)
- frameCount: Number of frames in animation (1-255)
- frameDuration: Hold each animation cell for this many 60 Hz ticks (1-255). Logical tick rate is capped at 60/s (wall clock), independent of Engine loop speed.
- reserved: Padding for alignment (future use)
Example: Water animation with 4 frames, 8 ticks per frame (~133 ms per cell at 60 Hz)
This structure is stored in PROGMEM (flash memory) sizeof(TileAnimation) == 4 bytes
