Velocity and Yaw

Hello, Im trying to make it so you can ride a bat.
I got X and Z velocity working, but i cant get Y to work.
Any of you good with math and can show me what to put to get Y-asis working?

PHP:

                    Vector v = new Vector();
                   
                    Float dirX = (float) (0 - (Math.sin((p.getLocation().getYaw() / 180) * Math.PI) * 1));
                    Float dirZ = (float) (Math.cos((p.getLocation().getYaw() / 180) * Math.PI) * 1);
                   
                    bat.setVelocity(v.setX(dirX));
                    bat.setVelocity(v.setZ(dirZ));

 

I don't know what you want it to look like, but can't you just use bat.setPassenger(player)?

 

chasechocolate No, im looking for someone who can figure out:
Float dirY = (float) (??????); the dirY

TheTinySpider , maybe you could get the Location of the entity that you get the yaw, and use getDirection()
Or toVector()

I think that includes the Y.

Example: player.getLocation().getDirection() (this is a vector) or player.getLocation().toVector()
