[SOLVED]Making armor undamageable/making lightning spawn on right click

[starwarsmace]

Hello guys. So I have two questions.

 

1.How do I make my armor undamageable(is this a word  )?

2.How would I make lightning spawn on right click. I already know how to make lightning spawn. But I don't get how you know where a player right clicks even if its 5 blocks away.

1) I am not certain, but setting the maxdamage to negative value Should work, because the game checks if the current damage value is 0.

2) With a simple raytrace, you can find an example in Minecraft class using the player's arm length as max raytrace length.

I will try putting the maxdamage to a negative value but can you please explain the raytrace?

 

Edit: I put the maxdamage to a negative value and it worked. Thanks.

I went and looked up raytrace and found out all about vectors and such. And after a lot of tinkering around I came up with this.

public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player) {

         MovingObjectPosition objectMouseOver;
         Minecraft mc = Minecraft.getMinecraft();

         objectMouseOver = mc.thePlayer.rayTrace(300, 1);

         if (objectMouseOver != null && objectMouseOver.typeOfHit == MovingObjectType.BLOCK) {

            int i = objectMouseOver.blockX;
            int j = objectMouseOver.blockY;
            int k = objectMouseOver.blockZ;
            world.spawnEntityInWorld(new EntityLightningBolt(world, i, j, k));
            if (!world.isRemote) {
            	Random rand=new Random();
            	int num=rand.nextInt(6);
            	if(num == 1){
            		if(world.getBlock(i+1, j+1, k)==Blocks.air){
            			world.setBlock(i+1, j+1, k, Blocks.fire);
	            	}
            		
            	}
            	if(num == 2){
            		if(world.getBlock(i, j+1, k+1)==Blocks.air){
            			world.setBlock(i, j+1, k+1, Blocks.fire);
	            	}
            		
            	}
            	if(world.getBlock(i, j+1, k)==Blocks.air){
            		world.setBlock(i, j+1, k, Blocks.fire);
            	}
               
               
            }
         }

    

      

      return itemStack;
   }

It worked pretty well. Thanks for pointing me in the right direction.

Why are you using the client instance of type EntityPlayer while there is an EntityPlayer object in the parameter?
