I have a grenade in my mod which is thrown and on contact with an object or entity explodes. the explosion does not hurt entities and appears to break blocks but the blocks are only invisible. When you leave the world and get back on it the blocks revert to being visible again. If anyone could tell me how to fix this that would be great! Code for the grenade entity below.

 

 

package com.krazykid1117.entity;

 

import net.minecraft.entity.Entity;

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.util.MovingObjectPosition;

import net.minecraft.world.World;

 

public class EntityGrenade extends EntityThrowable{

 

public EntityGrenade(World p_i1776_1_) {

super(p_i1776_1_);

}

public EntityGrenade(World world, EntityLivingBase entity){

super(world, entity);

}

@Override

protected void onImpact(MovingObjectPosition p_70184_1_) {

for(int i = 0; i < 10; i ++){

this.worldObj.spawnParticle("largesmoke", this.posX, this.posY, this.posZ, 0f, 0f, 0f);

}

 

if(!this.worldObj.isRemote);

this.setDead();

if(this.worldObj.isRemote){

this.worldObj.createExplosion((Entity) null, this.posX, this.posY, this.posZ, 5.0f, true);

}

 

}

 

}

 

 

Try this:

 

protected void onImpact(MovingObjectPosition p_70184_1_) {
  if(!this.worldObj.isRemote) {
    this.worldObj.createExplosion((Entity) null, this.posX, this.posY, this.posZ, 5.0f, true);
    this.setDead();
  }
}

 

You only need to create explosion in server side. The explosion data would be transported to client side via network.

The last parameter of createExplosion decides whether to destroy blocks. Set it false if you don't want blocks destroyed.

First of all, this line:

 

if(!this.worldObj.isRemote);

does nothing but waste CPU cycles.

 

And then you explicitly create the explosion only on the client. That's not gonna work.

Try this:

 

protected void onImpact(MovingObjectPosition p_70184_1_) {
  if(!this.worldObj.isRemote) {
    this.worldObj.createExplosion((Entity) null, this.posX, this.posY, this.posZ, 5.0f, true);
    this.setDead();
  }
}

 

You only need to create explosion in server side. The explosion data would be transported to client side via network.

How do I get this to happen on the server's side?

(If this is something very simple that I am missing I am sorry I am new to coding.)
