A Rust framework for building browser games with WASM.
This framework was inspired by the Game of Life Rust + WASM Tutorial. You can dive right in and start writing a wasm-rgame application with the tutorial!
This framework abstracts away writing custom HTML/Javascript and provides Rust types that interface with the Javascript bundled in the wasm-rgame-js repository.
The Rust API provides types for: * Keyboard events * Mouse position and events * Rendering API to a 2D canvas * Spawning new objects in the Application
Also, a build tool (wasm-rgame-tools) is provided that builds the project (targeting wasm32-unknown-unknown), runs wasm-bindgen, and bundles together the generated WASM binaries and Javascript/HTML.
This project is mainly experimental, but has been used to make non-trivial applications (see wrg-snake).
These examples are taken from wrg-snake. Also note that these examples can't be run stand-alone as they require the Javascript/HTML framework.
Rendering a transparent overlay: ```rust use wasm_rgame::{Delegate, Graphics};
impl Delegate for MyObject { fn tick(..) {}
fn render(&self, graphics: &mut Graphics) {
// draw a transparent overlay over the game
graphics.draw_rect(
0.0,
0.0,
CANVAS.width() as f32,
CANVAS.height() as f32,
[255, 255, 255, 150]
);
}
} ```
Checking keyboard input: ```rust use wasmrgame::{KeyManager, keycodes};
pub fn storedirectionchange(&mut self, keymanager: &KeyManager) { // Don't let direction change if already going opposite direction let wanteddirection = if keymanager.keydown(keycodes::W) { Direction::Up } else if keymanager.keydown(keycodes::D) { Direction::Right } else if keymanager.keydown(keycodes::S) { Direction::Down } else if keymanager.keydown(keycodes::A) { Direction::Left } else { return; };
...
} ```
