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

const createExplosion = require("../entities/explosion");

module.exports = function collision(state) {
  for (const b of state.bullets) {
    if (!b.alive) continue;

    for (const e of state.enemies) {
      if (!e.alive) continue;

      if (b.x === e.x && b.y === e.y) {
        e.alive = false;
        b.alive = false;

        state.score += 10;
        state.explosions.push(createExplosion(e.x, e.y));

        break; // 🛑 bullet stops after first hit
      }
    }
  }

  // 🧹 CLEAN UP DEAD ENEMIES
  state.enemies = state.enemies.filter((e) => e.alive);

  // 🧹 CLEAN UP DEAD BULLETS (🔥 IMPORTANT)
  state.bullets = state.bullets.filter((b) => b.alive);
};
