Care

Care is a very simple game framework focused solely on ease of use. The api is heavilty inspired by Löve 2D.

Hello World

Here’s the source code for hello world with care, making a window appear that displays “hello world” (using the love2d-inspired interface).

#[care::draw]
fn draw() {
    care::graphics::text("Hello, World!", (20, 20));
}

care::main!();

You can also use the async interface (inspired by macroquad) if you want:

#[care::async_main]
async fn main() {
    loop {
        care::graphics::text("Hello, World!", (20, 20));

        care::event::next_frame().await;
    }
}

care::main!();

See examples in the examples directory or the rust doc for more information.

Modules

compute

Contains functions for using GPU Compute (GPGPU)

config

Global care configuration parameters

event

Low-level event handling

math

Contains functions for doing various math tasks, including working with vectors

mouse

Stuff for working with a mouse

prelude

Useful structs to have imported

window

Contains functions for working with window(s)

Macros

main

Inserts a default main function that automatically initializes the framework, opens a window, and calls the functions marked by init, update and draw at appropriate times

Attribute Macros

async_main

Mark a function as the care draw function.

draw

Mark a function as the care draw function.

init

Mark a function as the care initialization function.

state

Make some state for the game

update

Mark a function as the care update function.
