Struct DrawQueue

pub struct DrawQueue<'frm> {
    pub sprites: FixedVec<'frm, SpriteQuad>,
    pub scale_factor: f32,
}

Queue of draw commands to be sorted and shipped off to the platform for rendering and some related rendering state.

Intended to be recreated every frame, but can be reused between frames to avoid having to queue up the draws again.

Fields

sprites: FixedVec<'frm, SpriteQuad>

Sprites to draw.

scale_factor: f32

Platform::draw_scale_factor, stored here because all sprite rendering needs it, and also has access to the draw queue.

Implementations

impl<'frm> DrawQueue<'frm>

pub fn new( allocator: &'frm LinearAllocator<'_>, max_quads: usize, scale_factor: f32, ) -> Option<DrawQueue<'frm>>

Creates a new queue of draws.

pub fn dispatch_draw( &mut self, allocator: &LinearAllocator<'_>, platform: &dyn Platform, )

Calls the platform draw functions to draw everything queued up until this point.
