#attackEntityWithRangedAttack -- my EntityBlasterBolt seems to be returning null cannot figure out why it works fine except in this method

    public void attackEntityWithRangedAttack(EntityLivingBase target, float distance)
    {

        int i = EnchantmentHelper.getEnchantmentLevel(Enchantment.power.effectId, this.getHeldItem());
        int j = EnchantmentHelper.getEnchantmentLevel(Enchantment.punch.effectId, this.getHeldItem());
        entityblasterbolt.setDamage((double)(distance * 2.0F) + this.rand.nextGaussian() * 0.25D + (double)((float)this.worldObj.getDifficulty().getDifficultyId() * 0.11F));

Man, if only I knew where it was crashing...might possibly be EntityBlasterBolt.java line 94?

No, that couldn't possibly be it.

Read your god damn crash reports. If you still can't figure it out, post your damn code.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Considering that you haven't posted your damn code, how the fuck should I know?

Ohhh man, I am so dumb I was looking at the wrong line 94. Thanks (no need to curse though)!
