Trait CameraDrawContext 

pub trait CameraDrawContext {
    // Provided methods
    fn quad(&mut self, corners: [[f32; 3]; 4], argb: u32) -> bool { ... }
    fn sprite(
        &mut self,
        name: &str,
        corners: [[f32; 3]; 4],
        uv: [[f32; 2]; 4],
        argb: u32,
    ) -> bool { ... }
}

What block_screen_effect_draw draws with, one per hook call: quads in camera space, in blocks, with +x right, +y up and the camera at the origin looking down -z. It is the space of ScreenEffectRenderer’s own quads, whose whole-view quad has corners at (±1, ±1, -0.5), under the first-person hand’s projection. Quads draw in the order given, after the level and the hand and before the GUI, alpha-blended with no depth test; give corners in order round the quad.

Provided Methods

fn quad(&mut self, corners: [[f32; 3]; 4], argb: u32) -> bool

A quad of corners corners in solid argb. False, with nothing drawn, for a coordinate that is not finite.

fn sprite( &mut self, name: &str, corners: [[f32; 3]; 4], uv: [[f32; 2]; 4], argb: u32, ) -> bool

A quad of corners corners showing sprite name of the game’s 2D atlas (block/fire_1, misc/underwater), with uv the texture coordinates of each corner in sprite units (0 to 1 is the sprite once; beyond that it repeats), every texel multiplied by argb. False, with nothing drawn, when there is no such sprite or a coordinate is not finite.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
