Struct Camera2D 

pub struct Camera2D {
    pub rotation: f32,
    pub zoom: Vec2,
    pub target: Vec2,
    pub offset: Vec2,
    pub render_target: Option<RenderTarget>,
    pub viewport: Option<(i32, i32, i32, i32)>,
}

Fields

rotation: f32

Rotation in degrees.

zoom: Vec2

Scaling, should be (1.0, 1.0) by default.

target: Vec2

Rotation and zoom origin.

offset: Vec2

Displacement from target.

render_target: Option<RenderTarget>

If “render_target” is set - camera will render to texture.

Otherwise to the screen.

viewport: Option<(i32, i32, i32, i32)>

Part of the screen to render to.

None means the whole screen.

Viewport do not affect camera space, just the render position on the screen.

Useful for things like splitscreen.

Implementations

impl Camera2D

pub fn from_display_rect(rect: Rect) -> Camera2D

Will make camera space equals given rect.

impl Camera2D

pub fn world_to_screen(&self, point: Vec2) -> Vec2

Returns the screen space position for a 2d camera world space position.

Screen position in window space - from (0, 0) to (screen_width, screen_height()). When a viewport is set, returns coordinates within that viewport’s screen region.

pub fn screen_to_world(&self, point: Vec2) -> Vec2

Returns the world space position for a 2d camera screen space position.

Point is a screen space position, often mouse x and y.
