Calculate the shortest way to rotate, right or left?

Question

Im making a simple computerplayer to my simple 2d action game. it suppose to turn towards me and shoot, but i cant figure out how to calc the shortest path... should it turn left of right if it want to shoot and kill me :P ?

Ive got two angles: cpu_facing (direction the cpu is facing) and player_degree (the angle calculated when cpu is in the center).

(im working with degrees, dont like radian :P)

Anyone done this in javascript?

Answer 1

(cpu_facing-player_degree+360)%360>180

• false: turn in the negative direction
• true: turn in the positive direction
