open-oak
open-oak
is a 2D game engine based on OpenGL written in Rust. It uses
glium for openGL bindings.
This project is in very early stages.
Features
- Rendering textured objects on the screen
- Handling window, mouse, and keyboard events
- Collission detection
Example
Below is a simple example that renders a textured block to the screen.
use glium::Surface;
use open_oak::events::handle_events;
use open_oak::init::{init, Game};
use open_oak::rectangle::Rectangle;
use open_oak::resource_manager::ResourceManager;
use open_oak::traits::{Renderable, Shaders, Texture};
use cgmath::Vector2;
struct Block {
rect: Rectangle,
}
impl Block {
fn new(position: Vector2<f32>, size: Vector2<f32>, color: imaopen_oak::Rgba<f32>) -> Block {
let rect = Rectangle::new(position, size, color);
Block { rect }
}
}
fn main() {
// init game and destructure
let game = init();
// destructure fields off Game
let Game {
display,
event_loop,
mut resource_manager,
..
} = game;
// define block
let mut block = Block::new(
Vector2::new(0.5, 0.5),
Vector2::new(0.3, 0.3),
imaopen_oak::Rgba::from([1.0, 0.0, 0.0, 1.0]),
);
// init rectangle
Rectangle::init(&mut resource_manager, &display);
// load block texture
let texture_name = String::from("block");
let texture = ResourceManager::load_texture(&display, "textures/block.png");
resource_manager.add_texture(&texture_name, texture);
// set block texture
block.rect.set_texture(texture_name.clone());
// game loop
event_loop.run(move |ev, _, control_flow| {
// handle events, keyboard input, etc.
handle_events(ev, control_flow);
let mut frame = display.draw();
frame.clear_color(0.2, 0.3, 0.3, 1.0);
// DRAW START
block.rect.draw(&mut frame, &resource_manager).unwrap();
frame.finish().unwrap();
// DRAW END
});
}
Development
I am very happy for any contributions!
To contribute, fork the repository, then edit the source code.
You can create a binary crate and put some example code in
there, so you can verify that the game engine is still working, and that your new
feature/bug fix/whatever is working as intended.
In the Cargo.toml
of your binary crate, you can link to your local version of ge
:
# --snip --
[dependencies]
`ge = { path = "/path/to/ge" }`
# --snip --
When you are done making changes, submit a pull request!
TODOs
- Implement collission detecting for circle and rotated rectangle
- Clean up the trait code, probably get rid of the macros in
macros.rs
as it's a code smell and replace it with less OOP-like code
