Why do monsters spawn in my house

Since the light emitted forms a circle, If you put a torch on each corner of a 12x12, the center would have the lowest light level because of how the light radiates. I have no clue what the exact light level is, it doesn't appear "dark", but perhaps it is just dark enough.

I think it may just be a bug. I have had mob spawn in my houses too when there should be no way for them to get in or spawn. But zombies can open wood doors if you didn't know that. They will bang on them a few times then they will open. Was this reply helpful? How satisfied are you with this reply?. Pretty sure they can't break down doors yet. It's a bit later when they start dropping rotten flesh and ingots. If it's possible, use half slabs for the floor. They can't spawn on any half slab.

Player placed walls should prevent monster spawning, but since they don't, I guess I'll just have to make every room NPC suitible Though I think that with the new blue dungeon slab wall and some other new walls , the player-placed thing doesn't prevent monsters from spawning anymore since monsters could spawn in my Truffle-house as well completly made out of mushroom walls etc and was NPC suitable, I even placed blocks on each side of the door so he couldn't let monsters in but the monsters still got in because they just spawned inside.

Clowns no longer destroy blocks, if I remember correctly. I think it might be that you used too much dungeon bricks which can make a mini-dungeon.. If its not that I wouldn't know whats causing it and can only say maybe build your house elsewhere or make another world..

Yeah I know Clowns don't destroy blocks anymore, but if one of those bombs blow up near furniture then you can go replace your furniture. And too much dungeon brick doesn't create a mini dungeon, since I don't see any dungeon enemies, don't hear dungeon music etc.

Building my house elswhere isn't going to work and making a new world won't work too, because I think the monsters will still spawn I had it in my other world too, had a smaller house but they still spawned inside of it while they didn't had that before 1. I still think the player-placed walls don't prevent monster spawning anymore since one of the updates after 1. Then I really think its bugged, I started Terraria just after to check and none of my worlds seem to have monsters spawning inside my bases..

My base is pretty big, I can never see the left and right at the same time or the up and down at the same time and I spend a lot of time inside my house decorating so monsters have enough time to spawn.

But yeah, it might be bugged so I'll just hope for a fix. Mayate View Profile View Posts. Originally posted by LittleRedQuinn :. Per page: 15 30 Date Posted: 15 Mar, pm.

Be wary of placing torches on sand columns which may fall. If such a torch is destroyed, you may find a creeper or other mob which spawned in the darkness.

If you discover a natural cave with a roof of sand or gravel, be extra careful. In the same manner that sand or gravel makes a poor choice for flooring or a foundation, obsidian is particularly good, due to its high explosion resistance. While it is unlikely that you will be able to produce enough obsidian to build entire walls or floors out of it, it can still be used for foundations, wall trim, and entrance frames.

Note: The cactus has to be on sand. Under the sand, place a blast resistant block like obsidian. If you mine below it, the obsidian warns you not to dig up or an alternating row of cacti and flames from netherrack to keep mobs from passing through it. Widely considered to be the most dangerous mob except the bosses in Minecraft is the creeper, because of the damage it causes to buildings they can effectively blow large holes in your structures.

However, you are safe within your base if there are creepers outside, as they can't get close enough to you to explode. You might even be able to open your door and kill the creeper with a bow and arrows, as long as you keep your distance! Also, be aware that creepers can detect you and start their fuse from one block away, even if there is a low wall or fence keeping them away. Ways to avoid this are: build a wall at least two full blocks tall even if it is made of certain translucent blocks such as slabs , fence or glass ; or build your home with all spawning surfaces on all traversable paths sufficiently lit.

Different blocks have different resistances to explosions. Dirt walls will be easily destroyed by creepers, while two block thick cobblestone will resist most creeper explosions. Obsidian is explosion-proof with the exception of blue wither skulls, so you can laugh in the face of creepers trying to destroy walls built of this block. Cats are also a good defense, as creepers will run away if they are in a short distance of one. Even if you've attacked the creeper, it will run away as long as there is a cat nearby, so it is a good idea to put cats around your base.

Spiders are two blocks wide, which means they cannot move through 1-block wide spaces. Skeletons are dangerous because they can fire arrows through gaps in your defenses. Wherever possible, fill open gaps with any of certain translucent blocks such as slabs, fence, or glass to make windows.

Additionally, build low walls or fences in places where you may be in the range of a skeleton since they will only fire arrows at you if they can see you. Spider jockeys are dangerous because of combining the climbing and tracking abilities of Spiders with the ranged attacks of Skeletons. You must combine your defensive strategies for both skeletons and spiders.

They're relatively rare, so it is unlikely, but not impossible, to encounter more than one Spider Jockey on the same night. Zombies are the simplest mob to defend against. With limited mobility and no ranged attacks, walls or pits will be enough to keep them at bay. However, zombies can break down wooden doors to reach you if you're in Hard difficulty. If you're in Hard, you can make a piston door so that zombies cannot get through, or you may make an iron door.

Zombies very strongly prefer to smash the top half of a door, but can't jump and smash a door at the same time jumping resets their progress smashing the door , so putting a 1-deep hole in front of your door should prevent zombies from breaking down the door while still allowing mobs such as yourself to enter when the door is open. To prevent other mobs from using the entrance put a two high pillar of sand above the door, though this won't stop or even hurt the offending zombie.

A way to prevent zombies from breaking your doors is to put the doors in sideways, rendering them "open" when you close them.
