Fast Tilemap for Bevy

GPU-accelerated tilemap functionality for bevy. Aims at rendering tilemaps with lightning speed by using just a single quad per map (layer) and offloading the actual rendering to GPU. This should be faster than most other bevy tilemap implementations as of this writing.

Features

• Very high rendering performance.
• Tilemaps can be very large or have many "layers"
• Rectangular and isometric tile maps.

How it works

The whole tilemap (-layer) is rendered as a single quad and a shader cares for rendering the correct tiles at the correct position.

Thus each map layer works with two textures: One with integer data type, constructed and maintained internally for storing for each tile position which tile index should be displayed there. And a tile atlas that contains all the tiles which should be provided by you (see assets/).

Limitations

• Only tested on Windows, no WASM support
• Overlapping "tiles" can not be rendered due to how the shader is designed, this may be changed in the future.
• No direct animation support
