Thank you for all of the replies, I got it working. I derped out for a couple of days to suddenly realize that y is up and down and put in the wrong parameters for math.atan2. so instead of this Math.atan2( directionY , directionX) which is what I used before, I did this to fix it Math.atan2( directionX, directionZ )

Here's the rundown of my mod. This is a turret/sentry gun mod for minecraft, this is also my first mod. I can place down the turret and it is able to rotate 360 degrees on the y axis(I've tested this). The turret also has a single inventory slot for ammunition. Here's the problem, I can get the entities I want to target within a given radius but I can't make the turret face the target. I'm a bit of a math noob( taking algebra 2 ), I've tried using Math.atan2 and Math.toDegrees with no success. Is there anyway to have the turret face the target based on the x and y coordinates of the target(assuming the turret is the center).
