Struct Camera2d 

pub struct Camera2d {
    pub center: Vec2,
    pub units_per_pixel: f32,
    pub zoom: f32,
}

2D orthographic camera. Owned by the UI (Repose signal), copied into the snapshot per frame.

Fields

center: Vec2

World-space center the camera looks at.

units_per_pixel: f32

World units per screen pixel at zoom 1. Combined with viewport size to build the ortho projection.

zoom: f32
