This is a short video showcasing the first build of cmdfx, a game engine for your terminal. This is the first build of the engine, and it’s still in development. The engine is written in C and C++, and it’s designed to be easy to use and flexible. It’s still a work in progress, but I’m excited to see where it goes.
The source code for this demonstration is available here.
The entirety of main.c is also available below:
#include <cmdfx.h>
#include <stdio.h>
CmdFX_Sprite* square = 0;
int width = -1;
int height = -1;
int running = 1;
int onKeyPress(CmdFX_Event* event) {
CmdFX_KeyEvent* payload = (CmdFX_KeyEvent*) event->data;
if (square == 0) return 0;
if (square->x < 0) return 0;
if (square->x + square->width >= width) return 0;
if (square->y < 0) return 0;
if (square->y + square->height >= height) return 0;
char c = payload->keyChar;
if (c == 'w') {
Sprite_moveBy(square, 0, -1);
} else if (c == 'a') {
Sprite_moveBy(square, -1, 0);
} else if (c == 's') {
Sprite_moveBy(square, 0, 1);
} else if (c == 'd') {
Sprite_moveBy(square, 1, 0);
}
if (c == 'q') {
Canvas_showCursor();
Screen_setEchoEnabled(1);
Screen_setLineBuffered(1);
running = 0;
}

Sprite_setForegroundAll(square, 0xFFFFFF);
