Prevent damage?

[Omegaa]

Hello, I've been making a new mod and I added this code:

@Override
 public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer Entityplayer) {

Vec3 look = Entityplayer.getLookVec();
 MovingObjectPosition Coord = Entityplayer.rayTrace(300, 1);
 EntityLightningBolt Lightning = new EntityLightningBolt(world, 1, 1, 1);
 Lightning.setPosition(Coord.blockX,Coord.blockY,Coord.blockZ);
 world.spawnEntityInWorld(Lightning);
 return itemStack;

 

to make lightning on right click, however in creative it works but in survival it damages the player, how can I prevent it from hurting the player but still hurt mobs and other players.

Thanks

You have to store the player's UUID in the lightning entity (getEntityData() gives you an NBTTagCompound to store your stuff in).

Then in EntityStruckByLighningEvent you then check if the player is the one that issued the lighting, by checking the UUID again. If they are, cancel the event.

 

I have tried a few times but couldn't seem to get the right code...

Could you give a example please?

	 EntityLightningBolt Lightning = new EntityLightningBolt(world, 1, 1, 1);
 Lightning.setPosition(Coord.blockX,Coord.blockY,Coord.blockZ);
 world.spawnEntityInWorld(Lightning);

 

Sigh.

 

Do you know what those 1s being passed to the constructor mean?

 

No, clearly you don't.

 

They're the entity's starting position.

 

EntityLightningBolt Lightning = new EntityLightningBolt(world, Coord.blockX,Coord.blockY,Coord.blockZ);

 

Amzanig!

Ok I fixed it slightly since Draco helped..

Thanks Draco!

Here is my current code:

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


	Vec3 look = Entityplayer.getLookVec();
	MovingObjectPosition Coord = Entityplayer.rayTrace(300, 1);
	         EntityLightningBolt Lightning = new EntityLightningBolt(world, 1, 1, 1);
	         Lightning.setPosition(Coord.blockX,Coord.blockY+1,Coord.blockZ);
	         world.spawnEntityInWorld(Lightning);
	  
	return itemStack;

but now I'm getting fire underneath me, I have tried to remove it but couldn't, any ideas?

Current code posted is identical to old code.

 

Anyway, your inability to kill the fire probably has to do with the fact that onItemRightClick is client-side-only.  When I was doing this kind of stuff, I had to use packets to properly make right-click functionality work correctly.

Lightning.setPosition(Coord.blockX,Coord.blockY+1,Coord.blockZ);

Coord.blockY+1

+1

But you didn't even change the thing I pointed out.
