Hello guys,

I am coding a boomerang. Its class extends "EntityThrowable". But, like snowballs, when they hit blocks like grass (I mean not the grass_block, I mean grass) they just "die"/"disappear". Is there any method to get the block hit by the entity? Here is my code:

public class EntityGoldenBoomerang extends EntityThrowable
{
	
    public EntityGoldenBoomerang(World par1World)
    {
        super(par1World);
    }
    public EntityGoldenBoomerang(World par1World, EntityLivingBase par2EntityLivingBase)
    {
        super(par1World, par2EntityLivingBase);
    }
    public EntityGoldenBoomerang(World par1World, double par2, double par4, double par6)
    {
        super(par1World, par2, par4, par6);
        
    }
    
    @Override
    protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
    {
        if (par1MovingObjectPosition.entityHit != null)
        {
            byte damageBoomerang = 3;
            par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), damageBoomerang);
        }
        if (!this.worldObj.isRemote)
        {
        	Random r = new Random();
        	if(r.nextInt(1000) <= 250) {
                        //Yes, Blaze Hit is the right sound
        		this.playSound("mob.blaze.hit", 0.5F, 0.4F);
            	this.entityDropItem(new ItemStack(ReforgedItems.GOLDEN_BOOMERANG), 0.0F);        		
        	} else {
                //Yes, lavapop is the right sound
            	this.playSound("liquid.lavapop", 0.5F, 0.4F);
        	}
        	this.setDead();
        }
    }
    
    @Override
    protected float getGravityVelocity() 
    {
		return 0.01F;
    }
    
}

remove

this.setDead();

in the final part of code

EntityThrowable#onImpact is called when the entity hits a block or another entity. Your current code should drop the item regardless of what the boomerang hit.

If MovingObjectPosition#typeOfHit is BLOCK, MovingObjectPosition#blockPos contains the position of the block that was hit.

If MovingObjectPosition#typeOfHit is ENTITY, MovingObjectPosition#entityHit contains the entity that was hit.

Side note: Don't create a new Random each time you need a random number, create one and store it in a field. In this case, the protected field Entity#rand already contains a Random.

No, because then the entity would never disappear. I only want it not disappearing when it hits locks like grass and such things

No problem, got it working with Choonster's tips... Thank you both!
