[1.18.1] Item to shoot fireball where player is looking on use

[jaxbymc42]

Hello!  I am trying to create an item that shoots a fireball in the direction of the player's view.  Currently, it does shoot the fireball but the fireball is curving a bit depending on where the player is looking (also, when looking down, even slightly, it shoots the fireball directly below the player).  I am struggling to figure out the problem.  I have already looked at other Minecraft classes, such as the Ghast and Bow classes.  Any help would be appreciated, thanks!

        ItemStack itemStack = player.getItemInHand(usedHand);
        Vec3 vec3 = player.getViewVector(1.0f);
        Random random = new Random();
        if (!level.isClientSide) {
            LargeFireball largeFireball = new LargeFireball(level, player, player.getX(), player.getEyeY(), player.getZ(), 1);
            largeFireball.shootFromRotation(player, player.getXRot(), player.getYRot(), 0.0F, 3.0F, 0.0F);
            level.addFreshEntity(largeFireball);
            level.playSound((Player)null, player.getX(), player.getY(), player.getZ(), SoundEvents.GHAST_SHOOT, SoundSource.NEUTRAL, 0.5F, 0.4F / (random.nextFloat() * 0.4F + 0.8F));
            if (!player.isCreative()) {
                itemStack.setDamageValue(itemStack.getDamageValue() + 1);
            }

try to use 1.0F as last parameter in shootFromRotation

The last parameter in the shootFromRotation method is for the inaccuracy.  In my case, it has nothing to do with the issue of the fireballs practically looping in circles whenever I use the wand item.

then you can test a bit with the speed
