Struct PointerMapping 

pub struct PointerMapping {
    pub origin: (f32, f32),
    pub scale: (f32, f32),
}

Maps window positions (physical pixels) to the space the game draws in, e.g. a virtual-resolution canvas scaled into the window: game = (window - origin) * scale. The toolkit sets it each frame from the renderer; see Input::set_pointer_mapping.

Fields

origin: (f32, f32)

Window position of the game space’s origin.

scale: (f32, f32)

Game pixels per window pixel.

Implementations

impl PointerMapping

pub fn apply(&self, pos: (f32, f32)) -> (f32, f32)

Map a window position to game space.

pub fn apply_delta(&self, delta: (f32, f32)) -> (f32, f32)

Map a movement in window pixels to game space.
