Struct gemini_engine::elements::Polygon

pub struct Polygon {
    pub points: Vec<Vec2D>,
    pub fill_char: ColChar,
    /* private fields */
}

The Polygon takes a vec of Vec2Ds and returns a polygon with those vertices when blit to a View

Fields

points: Vec<Vec2D>

fill_char: ColChar

Implementations

impl Polygon

pub fn new(points: Vec<Vec2D>, fill_char: ColChar) -> Self

pub fn generate_cache(&mut self)

Generate a BlitCache if you intend for the polygin to not move across multiple frames. If you use this, you MUST call generate_cache if the polygon does move in the future. This function will not generate a new cache if the previously generated cache is still valid

pub fn draw(vertices: Vec<Vec2D>) -> Vec<Vec2D>

Draw a polygon from points. Only supports convex polygons as of now

Trait Implementations

impl ViewElement for Polygon

fn active_pixels(&self) -> Vec<Point>

Return a vector of every coordinate where a pixel should be placed and its respective ColChar. If your whole object is a solid colour, consider using utils::points_to_pixels() which will add the same ColChar to every point and can then be used as this function’s output
