I'm trying to make Mob Spawners with WorldEdit. According to their wiki:

Mob spawner mob type
The mob spawner mob type can be specified after a pipe symbol (|).

Example: Setting mob type
//set mobspawner|Squid

I've tried this, and it doesn't seem to work, I still get a mob spawner with a pig inside. The pipe symbol (which I can type here fine as |) comes up as ¦ in the Minecraft console, is this a problem?

  • Are you in multiplayer. There's a glitch in which all spawners look like they have pigs inside.

  • No, single player.

  • Did you actually wait for something to spawn? At least in multiplayer it is a well-known bug that WorldEdit's mob-spawners show up as pig-spawners that spawn your desired mob but also client-only pigs

  • Yup. Set difficulty to hard and removed all torches - nothing spawns at all (no grass).

  • The pipe isn't the problem: pipe and "broken pipe" is just a font difference when it's the same input key. Jun 2, 2013 at 6:22

If you are using WorldEdit you must have Bukkit installed. If so install this plugin

With this, you'll be able to change the spawn to whatever you like.


I've found exactly what you're looking for here

You can craft mob spawners with ingredient, you just have to download Mod Loader and put some class in the .minecraft/mods folder. You should find instructions on his page. And yes it's for single player

    For single player?

The first of the other answer given is strange, so I have a solution for Single-player. For Single-player, there is no direct WorldEdit mod, it comes with the Single-Player Commands(or SPC) mod, as well as the Single-Player Console if you want to install it for Single-player. For more information on this, as well as installing the mods, visit SK's wiki.
