A performant way to render tilemap chunks has been added as the first building block to Bevy's tilemap support. You can render a chunk by supplying a tileset texture to the `TilemapChunk` component and tile data to `TilemapChunkTileData`. For each tile, `TileData` allows you to specify the index into the tileset, the visibility, and the color tint.

|
|
```rust
|
|
let chunk_size = UVec2::splat(64);
|
|
let tile_display_size = UVec2::splat(16);
|
|
let tile_data: Vec<Option<TileData>> = (0..chunk_size.element_product())
|
|
.map(|_| rng.gen_range(0..5))
|
|
.map(|i| {
|
|
if i == 0 {
|
|
None
|
|
} else {
|
|
Some(TileData::from_index(i - 1))
|
|
}
|
|
})
|
|
.collect();
|
|
|
|
commands.spawn((
|
|
TilemapChunk {
|
|
chunk_size,
|
|
tile_display_size,
|
|
tileset,
|
|
},
|
|
TilemapChunkTileData(tile_data),
|
|
));
|
|
```
