Terraria – How to keep Terraria NPCS from letting monsters in

terraria

I attached my NPC's house to mine so that they had access to both homes but they keep letting monsters in ): Is there a way to fix this?

This has also always bugged me in my first days of Terraria. NPC's are programmed to walk to the left and right, even if there are doors in the way.

What I always do is that I build the NPC building on top of my house, or floating 8 blocks above the ground, so that the mobs can't reach them. From there I connect my base to the NPC building using platforms. Or whatever kind of block you prefer.

Either way, you can't just tell the NPC's not to use doors, the only time that they don't use them is during the night.
