Solved Is there anyway to disable baby mobs?

Easiest thing Might be to just not let them spawn and just sell like slime balls and what not in a store.
EDIT:
Not sure if you code or not but a simple line like below could fix that.

Code (Text):

    @EventHandler
    public void entitySpawn(EntitySpawnEvent event) {
        Entity entity = event.getEntity();
        if (entity instanceof Slime) {
            event.setCancelled(true);
        }

    }

 

If you want i can create the plugin, contact me in private

 

You dont need a specific fix for this, just limit the number of mobs per chunk (in config file) and get Mobstacker. Fix the real issue.

 

It denies all Slimes, but @FlyingLlama is right, there's a simpler answer to your problem

 

There is Slime#getSize()

Code (Java):

    @EventHandler
    public void entitySpawn(EntitySpawnEvent event) {
        Entity entity = event.getEntity();
        // Where X is the size and under you don't want spawning
        if (entity instanceof Slime && ((Slime)entity).getSize() <= X ) {
            event.setCancelled(true);
        }

    }

 

Welp, that's how you do that... There is no such thing as a baby magmacube/slimecube. They are sizes.

 

I believe there could be a worldguard flag for mobs that arent adult

Again, there is no such thing as baby Slime or Magma Cube.

 

Slime dont have the status Baby or Adult. It's indicated by the Entity Size. For the baby the Size is 1 (the default others: 2 and 4)
