Detecting player behind player

I was recently going through deleting some of my old plugin creations, when i came across one unsolved plugin I made. Basically it was meant to detect if one player hit another player in the back, and if this happened an effect would occur. After analysing the code, I have now realised that I set the directions to 180 degrees. This meant if a player attacked another player, they would need to be exactly 180 degrees behind them, which is near impossible. So obviously, I need to change the code to accept a wider angle variant (say between 160 and -160). However I am not sure how to approach this. Does anyone have any suggestions? Code is appreciated

Use less than and greater than comparators. This basically tests for a half circle behind the player.

Code:java

if(degrees >= 90 && degrees <= 270) {
    //do code here
}

Ok, and also, i am right in saying that 0 degrees is where the player is looking?
Thanks
