Fast Tilemap for Bevy

Lightning fast tilemaps for bevy.

Features

• Very high rendering performance (hundreds of fps, largely independent of map size)
• Tilemaps can be very large or have many "layers"
• Rectangular and isometric (axonometric) tile maps.
• Tiles can overlap either by "dominance" rule or by perspective
• Optional custom mesh for which the map serves as a texture

How it works

The whole map is rendered as a single quad and a custom shader cares for rendering the correct tiles at the correct position.

Thus each map 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 the other being a tile atlas that contains all the tiles. This one should be provided by you (see assets/ for atlas examples).

As of this writing, this should be (much) faster than most other bevy tilemap implementations out there.

Limitations

• Only tested on Windows, no WASM support
• No direct animation support, but you can easily update the tilemap in regular intervals to achieve the same (see Animation Example)

Related work

If you dont require all of bevy_fast_tilemaps performance and are looking for an approach that supports some more tile shapes and allows to treat each tile as a separate entity, take a look at bevy_ecs_tilemap which (among others) inspired this work.
