How to set-up SetVelocity to send a player 3 blocks

So hello there! I am trying to get a player to be sent 3 blocks and I have no idea to do this. From what I've seen around this area, Vectors is the way to go. So do you have a solution, a link to another thread(I searched but couldn't find anything), or maybe a link to somewhere else thats had this done before.

Thanks,

3 blocks... Up? That would be on the Y axis, so player.setVelocity(new Vector(0, 0.30, 0)). You're gonna have to play around with those numbers (note that altering the center number will change how high the player is launched) until you get what you want.

 

chasechocolate Oops forgot to mention to where the player is looking on the x or z axis. So how would you do that?

 

electrobricks try playing around with it:

Code:java

Location loc = player.getLocation();
Vector direction = loc.getDirection();
 
direction.multiply(1.5); //To make them get launched farther (or not as far)
direction.setY(0.5); //So they won't get shot into the ground
player.setVelocity(direction);

 

Code:java

// This will get the direction vector on the X & Z axis
// that the player is looking at.
Vector direction = player.getLocation().getDirection();
direction.setY(0);
direction.normalize();
 
// Now, here's where it gets tricky.
// If you want to teleport them, do this
//-----------------------
// Extend the direction vector by the number of blocks you want
// to travel the player.
direction.multiply(3);
 
player.teleport(player.getLocation().add(direction));
 
//---------------------------
// However, if you want to set their velocity so that it will
// throw them 3 blocks, you'll have to do more complex checks
// to see the kind of block they are standing on, then look at NMS
// to see the values of friction and then create a formula that will
// set the correct velocity...I'm not gonna do that though.
