so I found this ancient post and decided to see if it actually works still in 1.7.10, which is outdated anyway but less than this post, so as you may expect I got an absolute bucketload of errors. well I decided to update it to 1.7.10 anyway just because I wanted to have a staff that creates lightning on right click. Ladies and gentlemen, here it is! this bit of code updated to 1.7.10!

@Override
public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer){
float f = 1.0f;

float f1 = entityplayer.prevRotationPitch + (entityplayer.rotationPitch - entityplayer.prevRotationPitch) * f;

float f2 = entityplayer.prevRotationYaw + (entityplayer.rotationYaw - entityplayer.prevRotationYaw) * f;

double d = entityplayer.prevPosX + (entityplayer.posX - entityplayer.prevPosX) * (double)f;

double d1 = (entityplayer.prevPosY + (entityplayer.posY - entityplayer.prevPosY) * (double)f + 1.6200000000000001D) - (double)entityplayer.yOffset;

double d2 = entityplayer.prevPosZ + (entityplayer.posZ - entityplayer.prevPosZ) * (double)f;

Vec3 vec3d = Vec3.createVectorHelper(d, d1, d2);

float f3 = MathHelper.cos(-f2 * 0.01745329F - 3.141593F);

float f4 = MathHelper.sin(-f2 * 0.01745329F - 3.141593F);

float f5 = -MathHelper.cos(-f1 * 0.01745329F);

float f6 = MathHelper.sin(-f1 * 0.01745329F);

float f7 = f4 * f5;

float f8 = f6;

float f9 = f3 * f5;

double d3 = 5000D;

Vec3 vec3d1 = vec3d.addVector((double)f7 * d3, (double)f8 * d3, (double)f9 * d3);

MovingObjectPosition movingobjectposition = world.rayTraceBlocks(vec3d, vec3d1, false);

if(movingobjectposition == null){
return itemstack;
}

if(movingobjectposition.typeOfHit == MovingObjectType.BLOCK){
int i = movingobjectposition.blockX;


int j = movingobjectposition.blockY;


int k = movingobjectposition.blockZ;

world.spawnEntityInWorld(new EntityLightningBolt(world, i, j, k));
}
return itemstack;
}


So as you can see, the Vec3Ds have changed to simply Vec3s, and the method createVector into createVectorHelper. The method rayTraceBlocks_do_do has changed to rayTraceBlocks and the EnumMovingObjectType into MovingObjectType. I hope this was helpful, even though outdated.

I have made my own code similair to this but when i do it it puts fire beneath me, how do i remove it?

In 1.6.4 I found that you can do the same thing by using this code

public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
{
par1World.spawnEntityInWorld(new EntityLightningBolt(par1World, par2, par3, par4));
return true;
}

does this work for 1.7.10?

Dude, MrArcane, update this to 1.6.4, please! It kind of kills me, like World class doesn't have rayTraceBlock_do_do() method anymore. You can really save my head if you response in 2-4 days.

Getting errors at World world and Entityplayer entityPlayer. Help? BTW: I'm a total 100% noob at coding
