Summoning lightning bolt entity

[kenny2810]

I basically have an item, that when right clicked summonses a lightning bolt entity. I have been trying a variety of methods but none seem to work. The latest method I used was this:

What am I doing wrong? Is it the method, a parameter, or am I just messing up?

Lighting bolts are handled differently from normal entities. Use addWeatherEffect instead of spawnEntity.

 

Ah thanks for your help!

Sorry to be a bother, but I am still having issues. The problem is, I cannot summon lightning unless it is raining (I checked the code). Is there a way to override this?

float f = 1.0f;

        float f1 = player.prevRotationPitch + (player.rotationPitch - player.prevRotationPitch) * f;
        float f2 = player.prevRotationYaw + (player.rotationYaw - player.prevRotationYaw) * f;

        double d = (double)f;

        double d1 = player.prevPosX + (player.posX - player.prevPosX) * d;
        double d2 = (player.prevPosY + (player.posY - player.prevPosY) * d + 1.6200000000000001d) - (double)player.yOffset;
        double d3 = player.prevPosZ + (player.posZ - player.prevPosZ) * d;

        Vec3 vec1 = Vec3.createVectorHelper(d1, d2, d3);

        float f11 = MathHelper.cos(-f2 * 0.01745329f - 3.141593f);
        float f12 = MathHelper.sin(-f2 * 0.01745329f - 3.141593f);
        float f13 = -MathHelper.cos(-f1 * 0.01745329f);
        float f14 = MathHelper.sin(-f1 * 0.01745329f);

        float f15 = f12 * f13;
        float f16 = f14;
        float f17 = f11 * f13;

        double d11 = 5000d;

        Vec3 vec2 = vec1.addVector((double)f15 * d11, (double)f16 * d11, (double)f17 * d11);

        MovingObjectPosition position = world.func_147447_a(vec1, vec2, false, true, true);

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

            int x = position.blockX;
            int y = position.blockY;
            int z = position.blockZ;

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

            world.spawnEntityInWorld(lightning);

        }

 

This is the code I use in my mod and it works just fine

 

world is a World and player is an EntityPlayer

I know this is old but I couldn't find any new threads but I was wondering if anyone knows why mine crashes my game it is a java.lang.ExceptionInInitializerError
