Struct gust_render::view::View

source ·

pub struct View { /* private fields */ }

Expand description

A View is a 2D camera. It’s the screen viewport. You can make multiple views and use them as Minimap, 2nd player screen etc… The view is attached to a gust::Window.

Implementations

source

impl View

source

pub fn new(pos: Point<f32>, rect: Rect<f32>) -> View

Create a new View from a pos point and a Rect

source

pub fn reset(&mut self, rect: Rect<f32>)

Reset the rect if you don’t want to you can use (set_sizes)[]

source

pub fn set_center(&mut self, pos: Point<f32>)

Set pos of the view (usefull for game like 2D Zelda-Like)

source

pub fn set_viewport(&mut self, viewport: Rect<f32>)

Set the viewport of the view (the viewport is given as a float factor 0.5 / 1.0 / 0.2 etc) That way people can simply handle screen part.

source

pub fn set_sizes(&mut self, sizes: Vector<f32>)

Set the size of the rect

source

pub fn translate<T: Scalar + Into<f32>>(&mut self, offset: Vector<T>)

Move the view from actual position with the offset offset.

source

pub fn update(&mut self)

Update the view: Apply all transformations.

source

pub fn set_zoom(&mut self, zoom: f32)

Set the view zoom.

source

pub fn zoom(&mut self, zoom: f32)

Multiply the current zoom by this one.

source

pub fn get_zoom(&self) -> f32

Return zoom.

source

pub fn projection(&self) -> &Matrix4<f32>

Return projection Matrix4.

source

pub fn sizes(&self) -> Vector<f32>

Return sizes in a Vector.

source

pub fn postition(&self) -> Vector<f32>

Return position of the view in a Vector.
