Struct Camera2D 

Source 
pub struct Camera2D {
    pub x: f32,

Expand description

2D camera with position, zoom, and viewport.

Fields§

§x: f32§y: f32§zoom: f32§viewport_size: [f32; 2]§bounds: Option<CameraBounds>

Implementations§

Source§

impl Camera2D

Source

pub fn clamp_to_bounds(&mut self)

Clamp camera position so the visible area stays within bounds. If the visible area is larger than the bounds, the camera centers on the bounds.

Source

pub fn view_proj(&self) -> [f32; 16]

Compute the view-projection matrix as a column-major 4x4 array.

Maps world coordinates to clip space:

  • Camera position is centered on screen
  • Zoom scales the view (larger zoom = more zoomed in)
  • Y-axis points down (screen coordinates)
