Spawn slow fireballs random above player

Hi,

I am trying to spawn random fireballs above the player and have them fly down like small metors. But I have some problems with the vector calculation and the meteors are too fast.

Here is the code I have so far. The method param Location is where the player is aiming and the metors should land.

Code:

    public void dropMeteor(Location location) throws CombatException {
 
        // lets get a position above the location with a random offset
        Location origin = location.clone();
 
        for (int i = 0; i < getAmount(); i++) {
            origin = origin.add(MathUtil.RANDOM.nextInt(3), MathUtil.RANDOM.nextInt(5) + 3, MathUtil.RANDOM.nextInt(3));
            RangedAttack<ProjectileCallback> attack = new RangedAttack<>(getHolder(), ProjectileType.LARGE_FIREBALL, getTotalDamage());
            org.bukkit.entity.Fireball projectile = location.getWorld().spawn(origin, org.bukkit.entity.Fireball.class);
            projectile.setShooter(getHolder().getPlayer());
            projectile.setIsIncendiary(true);
            projectile.setFireTicks(100);
            attack.setProjectile(projectile);
 
            Vector direction = new Vector(location.getX() - origin.getX(), location.getY() - origin.getY(), location.getZ() - origin.getZ());
            direction = direction.normalize().multiply(MathUtil.RANDOM.nextInt(i));
            attack.setVelocity(direction);
            attack.run();
        }
    }

 

To slow the meteor down i would use: 'projectile.setVelocity(projectile.getVelocity().multiply(0.5));'
Also the fireballs fired later are faster. The speed can be 5 times faster when the 5th fireball is fired, because you used'direction = direction.normalize().multiply(MathUtil.RANDOM.nextInt(i));'

Like CoderCloud said, you'll have to adjust some values. You will want to make the random number like this:

Code:

MathUtil.RANDOM.nextDouble()

That creates a number from 0 to 1, so it can have no movement or go at full speed. You can make it a value between a range like this:

Code:

double min; //Minimum speed multiplier
double max; //Maximum speed multiplier
double speedmult = MathUtil.RANDOM.nextDouble()*(max - minx) + min;

 

Technius, CoderCloud, mmh this only works partially. It slows the meteor down now, but it still very fast and when I multiply the direction it does not hit the player anymore.

Isnt there a way to spawn a simple fireball like when a entity is shooting it, without the entity?
