Struct egaku2d_core::SimpleCanvas

pub struct SimpleCanvas { /* fields omitted */ }

Allows the user to start drawing shapes. The top left corner is the origin. y grows as you go down. x grows as you go right.

Methods

impl SimpleCanvas

pub fn set_default_color(&mut self, color: [f32; 4])

pub fn set_viewport(&mut self, window_dim: FixedAspectVec2, game_width: f32)

pub unsafe fn new(window_dim: FixedAspectVec2) -> SimpleCanvas

pub fn sprites(&mut self) -> SpriteSession

pub fn circles(&mut self) -> CircleSession

pub fn squares(&mut self) -> SquareSession

pub fn rects(&mut self) -> RectSession

pub fn arrows(&mut self, radius: f32) -> ArrowSession

pub fn lines(&mut self, radius: f32) -> LineSession

pub fn clear_color(&mut self, back_color: [f32; 3])

pub unsafe fn batch_circles<T, F: Fn(&T) -> &[f32; 2]>(
    &mut self,
    bots: &[T],
    func: F
) -> BatchCircle<T, F>

The closure is a function to extract a reference to the vertex data for a given object T

This function is unsafe because the reference returned by the closure must be a reference into a member of T.
