Hello all!

 

I have recently created a custom mob that is only around 3 pixel blocks high. When spawning the custom rendered mob, it appears for a brief second, turns black, and disappears. After searching for a while, if I dug up the block, it would fall out, and then fall into the block under it.

 

Testing with a pillar, I was able to get this image after spamming F2 to capture it: https://i.imgur.com/FcESXoK.png

 

To create this scenario, I placed the Spawn Egg on the Dirt Block off screen at the top. The mob falls like this until you break it, and then rinse and repeat until you get to bed rock where it then falls though the world.

 

Any help would be appreciated! Thanks!

 

have you tried expanding its bounding box?

i suggest you post your code for the mob so we can see what you are missing or whats messing it up

Here's the Entity File (Pretty Bare Bones):

	
public EntityCustomMob(World world) {
super(world);
}

protected void applyEntityAttributes() {
        super.applyEntityAttributes();
        this.getEntityAttribute(SharedMonsterAttributes.maxHealth).setBaseValue(10.0D);
        //this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.25D);
}

@Override
public EntityAgeable createChild(EntityAgeable p_90011_1_) {
return null;
}

 

I disabled the movement speed because I thought that might have been causing it, but it appeared not to.

try copy and pasting the cow entity into your class and merging the code

So I skimmed through and changed my Entity file to look like this *I only took what I needed*:

 

public EntityCustomMob(World world) {
super(world);
}

protected void applyEntityAttributes(){
        super.applyEntityAttributes();
        this.setSize(0.9F, 1.3F);
        this.getNavigator().setAvoidsWater(true);
        this.tasks.addTask(5, new EntityAIWander(this, 1.0D));
        this.getEntityAttribute(SharedMonsterAttributes.maxHealth).setBaseValue(10.0D);
        this.getEntityAttribute(SharedMonsterAttributes.movementSpeed).setBaseValue(0.25D);
}

public boolean isAIEnabled() {
    return true;
}

@Override
public EntityAgeable createChild(EntityAgeable p_90011_1_) {
return null;
}

 

However, adding these lines of Code to my Entity Class now generates errors when I attempt to spawn it.

you may need to use setSize. I had the same problem once.

Adjusting the above code to use setSize doesn't seem to alleviate the problem.
