FOSS gamedev and creative worlds

There should be an enemy-free mode where the enemies are prevented from spawning and you don't have to get scared over enemies. My reasoning is that if you are trying to build into a wall (which I am) you shouldn't have to deal with enemies. I didn't enable damage, but it broke into my house. That made me mad. I would like to play without having to deal with enemies. Plus, the enemies creep me out.

Get version 0.4, there are no mobs and there's support for mods. people have made mods adding mobs, and you can choose to install those or not.

If you have mobs, I'm guessing you have 0.3. Just add "only_peaceful_mobs = true" to your minetest.conf, and oerkki and dungeon masters will be despawned.
