Disable movement of mobs?

Is there a way to stop movement of all mobs in all worlds? I want to place mobs so they don't move from the block they're standing on but they can still attack players.

I don't want to go to the complexity of "if a mob stands off the block then teleport them back to the one they were on". Is there any way to do this?

Thanks!

 

This would involve using craftbukkit. I don't think this is possible with bukkit API yet.

 

Try repeatedly setting their velocity to 0, 0, 0

Be warned that this might be heavy on processor if the mob count is high

 

Or you create a custom mob without certain GoalFinders

 

Rocoty Sgt_Tailor I think I will try both of them. The thing I want to do is when you type "/buy building archer" it places a skeleton with fences around it (can't move anyway). But I want to make another one so there's a wither skeleton (boss) on top of a small mountain. The mob will just fly away wont it?

 

This isn't a *good* way of doing this, but you could just apply the SLOWNESS effect to a mob once they reach a certain block.

 

foodyling This want stop the movement though and that's really what I want (unless the slowness means it takes them a very long time to get off the block they're standing on.

 

Just apply level 30 Slowness for Integer.MAX_VALUE
target.addPotionEffect(new PotionEffect(PotionEffectType.SLOWNESS, Integer.MAX_VALUE, 30)); Technically, they might slowly move off, but it'd take a REALLY long time

 

foodyling Thanks. How long do you think they'll take to move from 1 block to another? And is it just the walking speed so they can still move quickly?

foodyling What does "target" represent as in "target.addPotionEffect"?

ThunderWaffeMC the player or LivingEntity who you want to add the PotionEffect to.

 

The entity you want to add it too, also, I'm pretty sure you're not going to have a zombie standing there for hours.

 

Correct me if I'm wrong but I think BKCommonLib has an EntityMoveEvent that is cancellable and it's not heavy on the processor. (http://dev.bukkit.org/bukkit-plugins/bkcommonlib/)

 

This can help you. It will also work with mobs I think. http://forums.bukkit.org/threads/how-to-freeze-players-without-having-it-look-glitchy.148549/

 

Thanks everyone.

Slowness LVL 6 is enough in 1.5.2 to completly stop an entity from moving, apply that with the Integer.MAX_VALUE and you get yourself an frozen mob

EDIT:
Entitys could potentialy move when jumping, apply Jump Boost -6 to also stop them from junping
