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

const createEnemy = require("../entities/enemy");
const { ENEMY_ROWS, ENEMY_COLS } = require("../config");

module.exports = function spawnEnemies(state) {
  state.enemies = [];

  const startX = 5;
  const startY = 2;
  const gapX = 4;
  const gapY = 2;

  for (let row = 0; row < ENEMY_ROWS; row++) {
    for (let col = 0; col < ENEMY_COLS; col++) {
      state.enemies.push(createEnemy(startX + col * gapX, startY + row * gapY));
    }
  }
};
