Struct Vision 

pub struct Vision { /* private fields */ }

An area of the vision grid: a set of cells (column, row from the bottom).

Implementations

impl Vision

pub fn is_empty(&self) -> bool

Returns if the area has no cells.

pub fn contains(&self, cell: (u32, u32)) -> bool

Returns if the area has a cell.

pub fn extend(&mut self, other: &Vision)

Adds the cells of another area to this one.

pub fn bounds(&self, grid: &VisionGrid) -> Option<WorldBounds>

Returns the world bounds of the area: the corner of its first cell and the far corner of its last one.

pub fn encode(&self, grid: &VisionGrid) -> Vec<u8>

Encodes the area as the quad tree of a QUAD_TREE_BIT_ARRAY record (see the module docs).
