Struct SpriteSheet 

pub struct SpriteSheet {
    pub pixels: Vec<u8>,
    pub flags: Vec<u8>,
}

128x128 indexed-color sprite sheet plus one flag byte per sprite.

Fields

pixels: Vec<u8>

One palette index per pixel, row-major, SHEET_W * SHEET_H long.

flags: Vec<u8>

Eight user flags per sprite, used for map layers and game logic.

Implementations

impl SpriteSheet

pub fn get(&self, x: i32, y: i32) -> u8

Read a pixel from sheet coordinates. Out of bounds returns 0.

pub fn set(&mut self, x: i32, y: i32, color: u8)

Write a pixel at sheet coordinates. Out of bounds is ignored.

pub fn sprite_pixel(&self, n: u32, px: i32, py: i32) -> u8

Read pixel (px, py) of sprite n, where px/py may run past 8 to read neighboring sprites (used by multi-sprite spr calls).

pub fn flags(&self, n: u32) -> u8

All eight flags of sprite n as a bitmask.

pub fn set_flag(&mut self, n: u32, flag: u8, value: bool)

Set or clear one flag (0..8) of sprite n.
