Velocities/Vectors

I'm making a kit plugin and am using a jump feature in one of them. I need to make the player jump upwards (Y) and go outwards the way they are looking, (F1, F2, F3, F4)
So far this is my code:

Code:java

  @EventHandler
  public void onInteract(PlayerInteractEvent e){
      Player player = e.getPlayer();
      if(plugin.kit.containsKey(player.getName())){
          if(plugin.kit.containsValue(5)){
              if(e.getAction() == Action.RIGHT_CLICK_AIR|| e.getAction() == Action.RIGHT_CLICK_BLOCK){
                  if(player.getItemInHand().getType() == Material.GHAST_TEAR){
                  player.setVelocity(player.getLocation().getDirection().multiply(3).setY(player.getVelocity().getY() + 2));
                  }
              }
          }
      }
  }

The problem with that code is that if the direction is up it gets messed up

anything?

Maybe because its angle is 360 and you can't have angle above 360.

maybe what?

 

Try

Code:java

Location loc = player.getTargetBlock(null, 2).getLocation();
Location loc2 = player.getEyeLocation();
Vector vec = new Vector((loc.getX() - loc2.getX()), loc.getY() - loc2.getY(), (loc.getZ() - loc2.getZ()));
player.setVelocity(vec);

doesnt work any better ): You can just look at the air and spam it to fly

I need this A.S.A.P any possible solutions, The problem is when you look up at the error it just make you fly.

Only allow them to jump if they are on the ground.

 

I would have thought this is pretty obvious. Or only allow them to use it once every 5 seconds or something

 

k thanks , what about a double jump ?

 

let them do it once, make them wait a short time(like 0.5 of a second) then let them do it again once more but not again for 5 seconds.
