Struct zaplib::QuadIns

#[repr(C)]
pub struct QuadIns {
    pub rect_pos: Vec2,
    pub rect_size: Vec2,
    pub draw_depth: f32,
}

QuadIns is the basis for most draw structs.This renders a rectangle. There are some default shaders available at QuadIns::SHADER.

Example usage with your own struct:

struct MyStruct {
  pub base: QuadIns,
  pub field1: f32,
  pub field2: f32,
}

And render using:

let s = MyStruct {
  base: QuadIns::from_rect(rect),
  field1: 0.0,
  field2: 0.0,
};
cx.add_instances(&SHADER, &[s]);

Fields

rect_pos: Vec2

The top-left corner position of the quad, in absolute coordinates.

rect_size: Vec2

The size of the quad.

draw_depth: f32

Z-index.
