Struct kiss3d::planar_camera::Sidescroll

pub struct Sidescroll { /* fields omitted */ }

A 2D camera that can be zoomed and panned.

Methods

impl Sidescroll

pub fn new() -> Sidescroll

Create a new arc-ball camera.

pub fn at(&self) -> Point2<f32>

The point the arc-ball is looking at.

pub fn set_at(&mut self, at: Point2<f32>)

Get a mutable reference to the point the camera is looking at.

pub fn zoom(&self) -> f32

Gets the zoom of the camera.

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

Sets the zoom of the camera.

pub fn look_at(&mut self, at: Point2<f32>, zoom: f32)

Move the camera such that it is centered on a specific point.

pub fn drag_button(&self) -> Option<MouseButton>

The button used to drag the Sidescroll camera.

pub fn rebind_drag_button(&mut self, new_button: Option<MouseButton>)

Set the button used to drag the Sidescroll camera. Use None to disable dragging.

Trait Implementations

impl PlanarCamera for Sidescroll

fn handle_event(&mut self, canvas: &Canvas, event: &WindowEvent)

Handle a mouse event.

fn upload(
    &self,
    proj: &mut ShaderUniform<Matrix3<f32>>,
    view: &mut ShaderUniform<Matrix3<f32>>
)

fn unproject(
    &self,
    window_coord: &Point2<f32>,
    size: &Vector2<f32>
) -> Point2<f32>

Computes the 2D world-space coordiates corresponding to the given screen-space coordiates.

impl Clone for Sidescroll

fn clone(&self) -> Sidescroll

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sidescroll

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
