Struct ChunkData 

pub struct ChunkData {
    pub grid_position: Vector2<i32>,
    pub size: Vector2<u32>,
    pub content: Box<[u8]>,
}

A copy of a layer of data from a chunk. It can be height data or mask data, since the type is erased. The layer that this data represents must be remembered externally.

Fields

grid_position: Vector2<i32>

The grid position of the original chunk.

size: Vector2<u32>

The size of the original chunk, to confirm that the chunk’s size has not changed since the data was copied.

content: Box<[u8]>

The type-erased data from either the height or one of the layers of the chunk.

Implementations

impl ChunkData

pub fn from_texture( grid_position: Vector2<i32>, texture: &TextureResource, ) -> Self

Create a ChunkData for the given texture at the given position.

pub fn swap_height(&mut self, chunk: &mut Chunk)

Swap the content of this data with the content of the given chunk’s height map.

pub fn swap_holes(&mut self, chunk: &mut Chunk)

Swap the content of this data with the content of the given chunk’s hole mask.

pub fn swap_layer_mask(&mut self, chunk: &mut Chunk, layer: usize)

Swap the content of this data with the content of the given chunk’s mask layer.

pub fn swap_height_from_list(&mut self, chunks: &mut [Chunk])

Swap the height data of the a chunk from the list with the height data in this object. The given list of chunks will be searched to find the chunk that matches grid_position.

pub fn swap_holes_from_list(&mut self, chunks: &mut [Chunk])

Swap the hole data of the a chunk from the list with the hole data in this object. The given list of chunks will be searched to find the chunk that matches grid_position.

pub fn swap_layer_mask_from_list(&mut self, chunks: &mut [Chunk], layer: usize)

Swap the layer mask data of a particular layer of a chunk from the list with the data in this object. The given list of chunks will be searched to find the chunk that matches grid_position.

Trait Implementations

impl Debug for ChunkData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
