How to set the speed and direction of a splash potion?

Is it possible to edit the splash potions speed and direction when they are thrown, eg. Like a snowball.

Some code I have pulled out of the arrow speed multiplier:

Code:

    @EventHandler
    public void playerThrowGrenade(ThrownPotion e) {
        Entity entity = e.getEntity();
        Vector speed = e.getVelocity()
        Entity projectile = e.getProjectile();
     
            Player p = (Player) entity;
            Vector vec = p.getLocation().getDirection();
 
                projectile.setVelocity(new Vector
                (vec.getX() * speed * 4.375,
                vec.getY() * speed * 5,
                  vec.getZ() * speed * 4.375));
 
    } 

Thanks.

Well more a less a bump, i think im getting closer to working it out.

PHP:

    @EventHandler
    public void playerThrowGrenade(ThrownExpBottle e) {
       
        String le1 = e.getShooter().toString();
        String le2 = le1.replace("CraftPlayer{name=", "");
        String player = le2.replace("}", "");
        Bukkit.broadcastMessage("GRENADE TEST");
        Bukkit.broadcastMessage(player);
       
            Player p = Bukkit.getPlayer(player);
            Vector vec = p.getLocation().getDirection();
 
 
                e.setVelocity(new Vector
                (vec.getX() + 4 * 4.375,
                vec.getY() + 4 * 5,
                  vec.getZ() + 4 * 4.375));
 
    } 

This code returns the error "Wrong method arguments used for event type registered", I'm assuming that its a simple fix

I think you want to use the ProjectileLaunchEvent, because a ThroenExpBottle event does not exist (every event ends with event in the name). Then check if the projectile is a exp bottle.

 

Cheers that worked perfectly
