a2x Build Status

a2x is a C framework I wrote for my video games. It runs natively on Linux and FreeBSD, and can be cross-compiled for Windows, GP2X, Wiz, Caanoo, Open Pandora, and HTML5.

Build

sudo apt install git build-essential python3
sudo apt install libpng-dev libsdl2-dev libsdl2-mixer-dev

cd ~
git clone git://github.com/alxm/a2x.git

export A2X_PATH="$HOME/a2x"
export PATH="$PATH:$A2X_PATH/bin"

cd a2x/make/a2x
make -j

Hello, World! Project

a2x_new generates a small one-file project that draws a square which you can move with the arrow keys or a gamepad.

a2x_new hello
cd hello/make/
make run

Starter Project Screenshot

All the code is in hello/src/main.c:

#include <a2x.h>

A_SETUP
{
    a_settings_stringSet(A_SETTING_APP_TITLE, "hello");
    a_settings_stringSet(A_SETTING_APP_VERSION, "1.0");
}

A_STATE(drawBox)
{
    static struct {
        int x, y;
        AButton *up, *down, *left, *right;
    } context;

    A_STATE_INIT
    {
        context.x = a_screen_widthGet() / 2;
        context.y = a_screen_heightGet() / 2;

        context.up = a_button_new();
        a_button_bind(context.up, A_KEY_UP);
        a_button_bind(context.up, A_BUTTON_UP);

        context.down = a_button_new();
        a_button_bind(context.down, A_KEY_DOWN);
        a_button_bind(context.down, A_BUTTON_DOWN);

        context.left = a_button_new();
        a_button_bind(context.left, A_KEY_LEFT);
        a_button_bind(context.left, A_BUTTON_LEFT);

        context.right = a_button_new();
        a_button_bind(context.right, A_KEY_RIGHT);
        a_button_bind(context.right, A_BUTTON_RIGHT);
    }

    A_STATE_TICK
    {
        if(a_button_pressGet(context.up)) {
            context.y--;
        } else if(a_button_pressGet(context.down)) {
            context.y++;
        }

        if(a_button_pressGet(context.left)) {
            context.x--;
        } else if(a_button_pressGet(context.right)) {
            context.x++;
        }
    }

    A_STATE_DRAW
    {
        a_pixel_colorSetHex(0xaaff88);
        a_draw_fill();

        a_pixel_colorSetHex(0xffaa44);
        a_draw_rectangle(context.x - 40, context.y - 40, 80, 80);
    }
}

A_MAIN
{
    a_state_push(drawBox, "Draw Box");
}

Cross-Compile for Other Platforms

I originally wrote a2x to make games for the Linux-based GP2X handheld. The following targets are also supported:

  • Emscripten (HTML5)
  • GPH SDK (Caanoo)
  • MinGW (Windows)
  • Open2x SDK (GP2X, Wiz)
  • Pandora SDK (Open Pandora)

Edit ~/.config/a2x/sdk.config with your SDK paths:

cd a2x/make/a2x
make config                    # Create default sdk.config file
nano ~/.config/a2x/sdk.config  # Edit with your own SDK paths
make config                    # Process changes
make -j -f Makefile.gp2x       # Cross-compile for GP2X or other
