Set arrow velocity and damage.

Ok, so I'm using p.launchProjectile(Arrow.class); inside of a PlayerInteractEvent. When they right click an item, it launches an arrow, however, it is too slow and only does 0.5 hearts to a player.

How can I make the arrows shoot faster and do more damage to players it hits? Thanks!

 

launchProjectile will return the Arrow entity, which you can then modify.

 

but how :O

 

Hrm... ok, so that link wasn't helpful and it seems like I was wrong about Arrow having useful methods. It seems you have to use NMS to set arrow damage (power):

Here's what I do:

Code:java

Arrow arrow = null;
            Location location = player.getLocation();
            location.setX(location.getX() + direction.getX() * (1 + Math.random() * arrowCount));
            location.setY(location.getY() + 1.5f);
            location.setZ(location.getZ() + direction.getZ() * (1 + Math.random() * arrowCount));
 
            arrow = player.getWorld().spawnArrow(location, direction, speed, spread);
 
            if (arrow == null)
            {
                sendMessage("One of your arrows fizzled");
                return SpellResult.FAILURE;
            }
 
            arrow.setShooter(player);
 
            if (useFire) {
                arrow.setFireTicks(300);
            }
 
            // Hackily make this an infinite arrow and set damage
            try {
                Method getHandleMethod = arrow.getClass().getMethod("getHandle");
                Object handle = getHandleMethod.invoke(arrow);
                Field fromPlayerField = handle.getClass().getField("fromPlayer");
                fromPlayerField.setInt(handle, 2);
                Method setDamageMethod = handle.getClass().getMethod("b", Double.TYPE);
                setDamageMethod.invoke(handle, damage);
            } catch (Throwable ex) {
                ex.printStackTrace();
            }
            arrow.setTicksLived(300);
