Struct rusty_gfx::Window

pub struct Window { /* private fields */ }

An OpenGL window for displaying graphics. Also the object through which you’ll receive input events (mouse, keyboard, etc.)

Implementations

impl Window

pub fn new(override_dimension: Option<u32>, window_title: &str) -> Self

By default, this will be a square window with a dimension of 1024 logical pixels. You can override the dimension by providing a value for override_dimension, for example: Some(1200).

window_title is for the OS to use on the bar above your window.

pub fn drawstart(&mut self)

Call drawstart() when you are ready to draw a new frame. It will initialize the next off-screen framebuffer and clear it to black.

pub fn drawfinish(&mut self)

Call drawfinish() when you are ready to finalize the frame and show it. You will need to call drawstart() again before you can draw() any shapes in a new frame. I think this method blocks until the hardware is ready for a frame (vsync), so an unconstrained loop (that runs fast enough) should run at 60fps on most displays.

pub fn poll_game_events(&mut self) -> Vec<GameEvent>

For convenience this method abstracts all the possible mouse and keyboard events to GameEvents, which are the events we care about for the game. The WASD and arrow keys map to directions, mouse clicks and space bar map to attacks, and the Escape key maps to quitting. Any number of events could have occurred since we last looked, so a Vec<GameEvent> is returned.
