hello guys it's again me with my entity now what i want to ask is if there is a specific code for if an entity projectile hits a block i wanna have that my entity projectile only explodes on block but now it's also exploding on entitys, so yeah... corect my code please

 

package invizzble.mods.nc.entities.projectiles;

import net.minecraft.block.Block;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.effect.EntityLightningBolt;
import net.minecraft.entity.effect.EntityWeatherEffect;
import net.minecraft.entity.monster.EntityBlaze;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

public class EntityStaffODarknessAmmo extends EntityThrowable{

    public EntityStaffODarknessAmmo(World par1World)
    {
        super(par1World);
    }
    
    public EntityStaffODarknessAmmo(World par1World,EntityLivingBase par2EntityLivingBase) {
        super(par1World, par2EntityLivingBase);

    }
    
    private int explosionRadius= 3;
    
    @Override
    protected void onImpact(MovingObjectPosition par1Movingobjectposition) {
        
        if (par1Movingobjectposition.entityHit != null)
        {
            byte b0 = 30;
            par1Movingobjectposition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)b0);
            this.setDead();
        }
        if(!this.worldObj.isRemote){
            this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, explosionRadius, true);
            this.setDead();
        }
        
        
    }
    
    @Override
    protected float getGravityVelocity()
    {
        return 0F;
    }

}

Look at MovingObjectPosition.typeOfHit. Also, I don't believe you should be calling setDead on the client for an entity which exists on both the client and the server.
