terraria cheat to stop monsters spawning in house?

Answer 1

mobs will spawn in your "house" if it is not considered a actual house by terraria standards, it must  be at least 5 blocks high, 7 blocks wide, have a door, a table, a chair a light source and there must be a complete wall behind it no gaps. be warned that ir it is a bloodmoon zombies can open your doors on there own so be sure to stay away from your settlement as mobs only spawn around you.
