My entity doesn't explode if it hits a block while a say it has to ,, am i using the wrong if statement?

 

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){ // i found the !this.worldObj.isRemote int the entityEgg and the EntitySnowball, why doesn't it explode?
            this.worldObj.createExplosion(this, this.chunkCoordX, this.chunkCoordY, this.chunkCoordZ, explosionRadius, true);
        }
        
        
    }
    
    @Override
    protected float getGravityVelocity()
    {
        return 0F;
    }

}

this.worldObj.createExplosion(this, this.chunkCoordX, this.chunkCoordY, this.chunkCoordZ, explosionRadius, true);

Surely you want .posX, .posY, and .posZ?

oh god --' that was a stupid one --' thanks

You were also telling the entity to die before it even checked that wether it was client or server... You are supposed to this.setDead(); in the if(!this.worldObj.isRemote) statement

yes that one was already fixed you know, it's like 2am here
