Code	/ ------------------ Random Dungeon Generator --------------------------------------- Change the room amount to generate more or less cells. Press and hold the mouse to scroll the world. *CREDIT*** * The Lord - For giving me the skill and knowledge to program this ***ADDITIONAL*** * You may be asking, 'What is this and why was it made?' Well, the answer is simple, I'm going to use this technique in a puzzle game I will be making in Unity 3D engine.
