Help with leap (velocity)

Ok, I'm very bad with these vectors.
I'm trying to make leap function.

I want to push player highly (Y + 10) and then push him back to the ground with high speed.
Is this possible?

 

test this:

Code:

p.setVelocity(p.getLocation().getDirection().multiply(1.5).setY(10));

Why not just:

Code:

Player ply;
 
ply.setVelocity(ply.getVelocity().add(0,10,0);

Then schedule a task to launch them back down after the apex of their jump.

 

This push backward.

 

This is because of Java math, you if @mythbustermapushes them backwards, the set the .add(0, 10, 0) to .add(0, -10, o)

 

Make 2 schedulers. (You know , delay stuff)
Push him up with a 0, Y , 0 vector in the first timer, push him down with an 0 , -3Y , 0 vector.
