[1.8.9] Lighting Sword

TheTroop · March 5, 2016

i am making sword which spawns lighting when attacks mob i know how to do this with older versions of minecraft but no ide how can i do this with 1.8.9

if someone can update this code

public boolean hitEntity(ItemStack par1ItemStack, EntityLiving par2EntityLiving, EntityLiving par3EntityLiving)
{
 fireEffect(3, par2EntityLiving);
 lightningEffect(par2EntityLiving);
 par1ItemStack.damageItem(1, par3EntityLiving);
 return true;
}
  
public void lightningEffect(EntityLiving par1EntityLiving)
{
 double x = par1EntityLiving.posX;
 double y = par1EntityLiving.posY;
 double z = par1EntityLiving.posZ;
 World world = par1EntityLiving.worldObj;
 EntityLightningBolt lightning = new EntityLightningBolt(world, x, y, z);
 lightning.setPosition(x, y + 1, z);
 world.spawnEntityInWorld(lightning);
}

That code will not work correctly even in older versions of Minecraft, so, don't lie.

You need to use addWeatherEffect to spawn lightning entities.

Woops. Looks like I'm doing this wrong, too, though it works just fine when I use it. I'll change it to use addWeatherEffect.

i updated my code i don't get any error but it don't seem to work either

	public ItemStack onItemRightClick(ItemStack par1ItemStack, World par1World, EntityPlayer par3EntityPlayer, double p_i1703_2_, double p_i1703_4_, double p_i1703_6_, EntityLivingBase par3EntityLivingBase)
	{

	par1World.addWeatherEffect(new EntityLightningBolt(par1World, p_i1703_2_, p_i1703_4_, p_i1703_6_));

	return par1ItemStack;
}

Item#onItemRightClick

doesn't have that signature, so you've created a new method that's never called instead of overriding the method that Minecraft calls.

Always add the

@Override

annotation to override methods so you get a compilation error if it doesn't actually override a super method. I suggest using your IDE to auto-generate override methods, this way the override method will always have the correct signature and the

@Override

annotation.

Be more specific. What doesn't like what? What's the error message and what part of the code is it for?

If

@Override

gives you a compilation error, the method doesn't override a super method.

But it doesn't seem to like it

The signature you're looking for is:

public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)

The signature you're looking for is:
public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)

java.lang.NullPointerException: Unexpected error
at net.minecraft.item.Item.getDamage(Item.java:939)

at com.Legendary.mod.items.tools.LMLimoniteSword.onItemRightClick(LMLimoniteSword.java:26)

A

NullPointerException

means that you tried to call a method or access a field of a null value.

If you look at

Item#getDamage

(line 939), the only value that's having a method called or a field accessed is the

stack

argument.

Item#getDamage

is being called with

null

as its argument from

LMLimoniteSword#onItemRightClick

(line 26).

i fixed it lighting bolt is spawning i can here sound but i can't see it i didn't know where it is spawning. i want it to spawn where i am looking at

TheTroop · March 5, 2016

I tried this but it dosn't like blockx , blockY, blockZ i have no ide to do this other way

	@Override
public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) {
      
          {
        	   MovingObjectPosition objectMouseOver = playerIn.rayTrace(200, 1.0F);

   			if (objectMouseOver != null && objectMouseOver.typeOfHit == MovingObjectType.BLOCK) 
   			{
   				int x = objectMouseOver.blockX;
   				int y = objectMouseOver.blockY;
   				int z = objectMouseOver.blockZ;
   				
   				worldIn.addWeatherEffect(new EntityLightningBolt(worldIn, x, y, z));
        	   
           }
           return itemStackIn;

TheTroop · March 5, 2016

Can anyone help ? :-[

Choonster · March 5, 2016

If you look at the

MovingObjectPosition

class in your IDE, you'll see that it doesn't have

blockX

/

fields. The position of the block that was hit is stored in the

blockPos

field as a

BlockPos

object which contains the individual coordinates.

Entity#rayTrace

is a client-only method, using it in common code like

Item#onItemRightClick

will crash the dedicated server. Use

ForgeHooks.rayTraceEyes

to ray-trace a custom distance, always ignoring liquids or use

Item#getMovingObjectPositionFromPlayer

to ray-trace the block reach distance (default is 5.0), optionally ignoring liquids.

Like regular entities, weather effects should only be spawned on the server (when

World#isRemote

is

false

).

Don't bump your thread, especially if it's still on the first page. People will respond when they have something to say, bumping will only annoy them.

TheTroop · March 5, 2016

I have no ide how to use ForgeHooks.rayTraceEyes are there any other way?

TheTroop · March 5, 2016

I have no ide how to use ForgeHooks.rayTraceEyes

What do you not understand about it?
Please try to at least have an attitude of "I want to learn", not just "feed me my code", "no this doesn't work, give other".

i don't understend how to use ForgeHooks i tryed. if you have any tutorials about how to use it pls give it me. i am searching for tutorials to learn how to mod. but there are a few ones on 1.8.9. i didn't say this doesn't work give me other no i sayd i dont understend how to use it and i am searching for ways that i can use. i am traing to make sword that spawn lighting where ar you looking at when righ click i read tutorial about raytrac outdated one and tryd to update it.

TheTroop · March 5, 2016

it is same as raytrace ?

if so how to do that this code give

EntityLightningBolt lightning = new EntityLightningBolt(world, x, y, z);

x, and z cordinants if theare ar no blockX, blockY, blockZ

TheTroop · March 5, 2016

it is my problem i dont know java and eithrt don't know enough english to learn java so best way of coding for my is tutorials with codes or video tutorials :-[

jeffryfisher · March 5, 2016

it is my problem i dont know java

This forum says that we don't teach Java here. Modders must find other Java help. I too started Forge modding without any Java experience. Nor had I ever used "reflection" in any language before. I invested two whole weeks immersed in the Minecraft source code before asking help here.

There are resources on the net for learning Java. Some Java tutorials might be in your language (search). Eclipse helps with Java too.

Eclipse also helps to trace code -- Learn to use Eclipse to find things like ForgeHooks.rayTraceEyes, and its parameters, and what it does.

i set up forgehooks.raytraceeyes look for vanila odes but can't figure out how i can get x y and z coords for spawning lightingbolt :C

i set up forgehooks.raytraceeyes look for vanila odes but can't figure out how i can get x y and z coords for spawning lightingbolt :C

ForgeHooks.rayTraceEyes

returns a

MovingObjectPosition

in the same post I told you to use

But addWeatherEffect dosn't like BlockPos

Choonster · March 6, 2016

But addWeatherEffect dosn't like BlockPos

You need to extract the individual x/y/z coordinates from the

BlockPos

. How about you look at

BlockPos

and its parent class to see how that can be done?

i looked for it in BlockPos.class and in Vec3i.class but non of the codes are familiar

I can't spoon feed you every piece of information. At some point, you're going to have to learn Java properly if you want to make a mod.

most of information you give me i don't understend becouse my knowledge of english so can you just tell me what port of this code i need to use for my sword? best way for me to teach something is read proper code
