Entity Velocities, Somewhat Advanced

I am trying to make a plugin in which one entity's velocity is set so that it will be launched towards another entity, and while I have done some sort of complicated things with velocities, I don't have a great understanding of what exactly a vector is or how to calculate such a velocity. If you know how to do this, please comment.

The vector between Entity A and Entity B is A.getLocation().subtract(B.getLocation()).toVector(). Let's call the vector 'link'.
Now that we have the linking vector. A.setVelocity(link.add(new Vector(0, 3, 0)).normalize() will launch the entity with a bit of lift and normalize it.

Note that this might not work exactly how you want it and I haven't worked with this stuff in a little bit so tweak it to your will.

Explanation above in code:

Code:java

                // Don't keep it null ...
        Entity a = null;
        Entity b = null;
        Vector link = a.getLocation().subtract(b.getLocation()).toVector();
        a.setVelocity(link.add(new Vector(0, 3, 0)).normalize());

 

Okay, I'll play with that. Thanks!
