[1.12.1] [Solved] Cannot interact with custom entity

[fcelon]

Hello,

I have created my own entity, but I can't interact with it. When I spawn it into the world, I can see it's hitbox, but clicking on it does nothing and I can even place blocks right into it. This is my entity code. What should I do to make the hitbox work?

import net.minecraft.entity.Entity;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.EnumHand;
import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.world.World;

public class EntityBallista extends Entity {
	
	public EntityBallista(World worldIn) {
		super(worldIn);
		this.setSize(3, 2);
		this.entityCollisionReduction = 1;
		System.out.println(this.getEntityBoundingBox());
		System.out.println(this.getCollisionBox(this));
	}
	
	@Override
	public AxisAlignedBB getCollisionBox(Entity entityIn) {
		return entityIn.getEntityBoundingBox();
	}
	
	public boolean processInitialInteract(EntityPlayer player, EnumHand hand)
    {
		System.out.println("Interacting");
        if (player.isSneaking())
        {
            return false;
        }
        else if (this.isBeingRidden())
        {
            return true;
        }
        else
        {
            if (!this.world.isRemote)
            {
                player.startRiding(this);
            }

            return true;
        }
    }

	@Override
	protected void entityInit() {
		
	}

	@Override
	protected void readEntityFromNBT(NBTTagCompound compound) {
		//super.readFromNBT(compound);
		
	}

	@Override
	protected void writeEntityToNBT(NBTTagCompound compound) {
		//super.writeToNBT(compound);
		
	}

}

Thanks for any help.

Without the readEntityFromNBT and writeEntityToNBT methods calling super, your entity on the client can't be synchronized with the copy on the server.

[fcelon]

With the readEntityFromNBT and writeEntityToNBT methods calling super, an infinite loop will be created (readFromNBT calls readEntityFromNBT). I have already tried this and the entity could not be summoned.

[Draco18s]

Then you need to not override the method. Overriding a method to do nothing is almost never the correct thing to do.

 

That or call the correct super method...super.readEntityFromNBT

Even without the @Override annotation calling the super.readFromNBT still causes the infinite loop.

@Override is just an IDE directive, it isn't actually compiled to bytecode

super.readEntityFromNBT doesn't work.

Cannot directly invoke the abstract method readEntityFromNBT(NBTTagCompound) for the type Entity

[Draco18s]

Oh, you're extending Entity directly. I missed that.

Not sure what's preventing you from interacting with it then.

[fcelon]

I just found it.

@Override
	public boolean canBeCollidedWith() {
		return true;
	}

After adding this to the code the entity works fine.
