Finally making some progress. I’m still stressed out and making dumb mistakes like trying to set a variable to a value using == and setting an array to equal another instead of the values contained in the array. Despite that I nearly finished the map system. The player can now travel to different rooms once all mobs are destroyed. Any weapons or power-ups persist in rooms, so going back to explored rooms is useful if the player needs some health they left behind. Speaking of health, mobs now drop health, and rooms are randomly populated with the the available mobs. I am experimenting with room sizes, player speed, and weapon heat buildup rates.
