Struct mold2d::viewport::Viewport

pub struct Viewport {
    pub x: i32,
    pub y: i32,
    pub window_dimensions: (i32, i32),
    pub map_dimensions: (i32, i32),
}

Constrains coordinates from an open world into the current window view This allows for scrolling for levels larger than the current screen

Fields

x: i32

The x value of the center coordinate of the viewport

y: i32

The y value of the center coordinate of the viewport

window_dimensions: (i32, i32)

Width and height of the window

map_dimensions: (i32, i32)

Width and height of the map

Methods

impl Viewport

fn new(window: &Window, map_dimensions: (i32, i32)) -> Viewport

fn in_viewport(&self, point: (i32, i32)) -> bool

Returns true if the point is inside the viewport, false otherwise

fn relative_point(&self, map_point: (i32, i32)) -> (i32, i32)

Returns the point in the game relative to the viewpoint

fn constrain_to_viewport(&self, rect: &Rect) -> Option<Rect>
