A spiritual greeting from your JavaScript code. Because every function deserves a 'Namaste 🙏'

const { BULLET_COOLDOWN, SCREEN_HEIGHT } = require("./config");
const createBullet = require("./entities/bullet");

module.exports = function initInput(state) {
  process.stdin.on("data", (key) => {
    const k = key.toString();

    if (k === "\u0003") {
      state.running = false;
      process.exit();
    }

    if (k === "a" || k === "\u001b[D") {
      state.player.x = Math.max(0, state.player.x - 1);
    }

    if (k === "d" || k === "\u001b[C") {
      state.player.x = Math.min(
        require("./config").SCREEN_WIDTH - 1,
        state.player.x + 1
      );
    }

    // 🔥 SPACE TO SHOOT
    if (k === " ") {
      if (state.bulletCooldown === 0) {
        state.bullets.push(createBullet(state.player.x, SCREEN_HEIGHT - 2));
        state.bulletCooldown = BULLET_COOLDOWN;
      }
    }
  });
};
