Struct fastanvil::BlockData

pub struct BlockData<T: Debug> { /* fields omitted */ }

Implementations

impl<T: Debug> BlockData<T>

pub fn at(&self, x: usize, sec_y: usize, z: usize) -> Option<&T>

Get the block data for the block at x,y,z, where x,y,z are relative to the section ie 0..16.

pub fn try_iter_indices(&self) -> Option<StatesIter<'_>>

Get iterator for the state indicies. This will increase in x, then z, then y. These indicies are used with the relevant palette to get the data for that block.

This returns None if no block states were present. This typically means the section was empty (ie filled with air).

You can recover the coordinate be enumerating the iterator:

for (i, block_index) in states.try_iter_indices().unwrap().enumerate() {
    let x = i & 0x000F;
    let y = (i & 0x0F00) >> 8;
    let z = (i & 0x00F0) >> 4;
}

pub fn palette(&self) -> &[T]

Get the palette for this block data. Indicies into this palette can be obtained via try_iter_indices.
