[1.7.10]Spawning Lightning Bolts

[Jetfan16ladd]

I am attempting to make a item that when right clicked will shoot lightning bolts. However I have tried everything and cannot get lightning bolts to spawn. Does anyone have any idea of how I could do this?

Here is the items class:

package com.mineturnedmod.mineturned.items;

import com.mineturnedmod.mineturned.EntityBolt;
import com.mineturnedmod.mineturned.EntityRpg;
import com.mineturnedmod.mineturned.Mineturnedmain;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.entity.effect.EntityLightningBolt;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntitySnowball;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class MjolnirClass extends Item
{
   public MjolnirClass()
   {
     super();
   setMaxStackSize(1).setFull3D();
   }
   @Override
   public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World,EntityPlayer par3EntityPlayer) {
       if(par3EntityPlayer.capabilities.isCreativeMode||par3EntityPlayer.inventory.consumeInventoryItem(Mineturnedmain.RpgAmmo))
       {
           par2World.playSoundAtEntity(par3EntityPlayer, "random.bow", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));
           if (!par2World.isRemote)
           {
               par2World.spawnEntityInWorld(new EntityLightningBolt(par2World, maxDamage, maxDamage, maxDamage));
           }
       }
           return par1ItemStack;
       }
@SideOnly(Side.CLIENT)
public void registerIcons(IIconRegister reg){
	this.itemIcon = reg.registerIcon("morecraftingmod:iron_sword_");
   } }

 

The problem is on the line spawn in world. The maxDamage is the default constructor that it tells me to put there but it doesn't spawn the lightning bolt.

Uhm, im pretty damn sure the maxDamage parameters are the x, y, z coords

How else would minecraft know where to spawn it?

[shadowfacts]

Why are you trying to spawn the entity at (maxDamage, maxDamage, maxDamage)? All three instance of "maxDamage" should be replaced with the x, y, and z coordinates respectively.

[Anon10W1z]

Just like you put maxDamage, maxDamage, maxDamage, I suggest you learn Java, learn Java, learn Java.

[Jetfan16ladd]

How do I put the x y z coordinates?

[Jetfan16ladd]

I want it to go horizontally to the block the player is facing.

[Jetfan16ladd]

Okay then How can I make it hit the block the player is facing vertically.

[BuddingDev]

You mean where the player is looking at / the cross-hair is pointed to?

Players may not always face vertically.

You can try using

MovingObjectPosition mop = Minecraft.getMinecraft().renderViewEntity.rayTrace(200, 1.0F);

It may help, considering you know how to extract data from the variable 'mop'.

[Jacky2611]

What, we can get the block the player is looking at at the server without packages?

I am pretty sure that i used some really complicated algorithm to archive this using the players head rotation. DAMN! (Cause I didn't want to add packages just for this one function.)

 

You put the x y z values by using EntityLightningBolt(par2World, z, y, x).  (yeah, its definitely zyx, not xyz )

[Jacky2611]

Can't believe i really wrote packages...

[Jetfan16ladd]

it says z, y, x cannot be resolved as variables. and btw where do I put MovingObjectPosition mop = Minecraft.getMinecraft().renderViewEntity.rayTrace(200, 1.0F);?

[Anon10W1z]

Learn Java. DO IT NOW.

[Jetfan16ladd]

Just out of curiosity how long would it take to learn the basic java stuff?

[Anon10W1z]

It doesn't matter, and it depends on willingness to learn and effort.

[Jetfan16ladd]

I don't want to spend a lot of time learning java as I only would be using it for this and maybe moding other games.

[Anon10W1z]

Learn it. It will come handy.

[shadowfacts]

Too bad, if you want to make a mod for Minecraft you will have to learn Java, because MINECRAFT IS BUILT IN JAVA.

[Jetfan16ladd]

Any one have a link to a video tutorial for the basic Java stuff?

[ImaFool]

I suggest you just use

onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10)
    

wich gives u the x,y,z coords off the block clicked.

note this will not work for clicking on air water and lava

[scoob27]

I wanted to do the same as you. Diesieben07 helped me and i figured out how to make them spawn.

 

Basically i used getMovingObjectPositionFromPlayer(...) that i copied in the class of my item, rename into getDistanceFromPlayer(...) and modified a bit in order to be able to adjust the distance the player can right-click (as diesieben07 suggested) and not the rayTrace(...) which is only client side. Then i test if the world is remote and if not i spawn the lightning.

 

You can have a look at the solution i used at the end of this topic :  http://www.minecraftforge.net/forum/index.php/topic,27030.0.html

 

Hope it helps

 

PS : i also think that you should learn Java before trying to create your mod. It will be easier to understand how everything work
