Three.js / Rotate object around its' Y-axis to look in particular direction

[marffinn]

I tried to wrap my head around it for at least a week, but it's too heavy for me.
The problem is that when I click on particular coordinates on the PLANE, i want my 3d model to rotate to face the new coordinates, and then change it's position to match the new coordinates ( it would be nice if you also explain to me how to declare objects' speed and move it with that speed ).

I know it has to do something with THREE.Matrix4() function.

(If You ever played starcraft or similar game, you'll know what I'm up to ;> )

Here is the so far THREE.JS code:
