[Tutorial] Make bow shoot the opposite direction

Just playing around with things. Thought i would share this cool piece of reference code.

Code:java

    @EventHandler
    public void onEntityBow(EntityShootBowEvent e){
 
        if(e.getEntity() instanceof Player){
            Player p = (Player) e.getEntity();
            Float speed = e.getForce();
            Arrow arrow = (Arrow) e.getProjectile();
            Vector vec = p.getLocation().getDirection();
            arrow.setVelocity(new Vector
                    (vec.getX() * speed * -1,
                    vec.getY() * speed * -1,
                    vec.getZ() * speed * -1));
        }
    }

 

Developing Would this spawn an arrow directly infront of the player and then since it is going backwards, hit the player?

 

BungeeTheCookie Nope. The arrow basically goes the opposite direction you are facing after you release the bow. Wouldn't hit you at all in any case.

 

This is an awesome resource. I will use this sometime

 

BungeeTheCookie Welcome

 

Bump.

 

Why should you use this?

 

To fire backwards without looking behind?

You could use this to look forward, and if you know somethings behind you, shoot backwards.

 

wouterrr Other than those above mentioned , you can use this to prank someone.

 

Why are you bumping it? This is resources, there's no reason to bump it...

 

Code:java

@EventHandler
public void BowShoot(EntityShootBowEvent event){
if(event.getEntity() instanceof Player)
event.getProjectile().setVelocity(event.getProjectile().getVelocity().multiply(-1));
}

 

Making the y velocity a negative means if you fire with a slight upwards direction, it will fire downwards, so I would leave the y velocity how it is, and only reverse the x and z.

 

You guys do realize this just makes the arrow hit the shooter itself...? xD

 

Wow. Look at the first post.

 

Wow. Look at the date.

 

Oops, didn't see it.
