Hi, I am fairly new to AS. I have a game where you kick the football around and try to score but I am having trouble programming the AI.

What I want him to do is always go towards the ball. But when the angle of the ball to him is over 180 degrees or under -180 he has to turn round the other way. He does this because he is programmed to add 6 to his degrees the angl of him to the ball is bigger then his rotation and visa versa. But when the ball crosses fromm 180 degrees to -179 he has to rotate the other way.

Here is the code:

Actionscript:

//CPU Player
function checkKeys1() {
	//makes CPU go forward
	accel1 = 0.85;
	//turn1 is the CPU's rotation
	walk1._rotation = turn1;
	rad1 = walk1._rotation*Math.PI/180;
	velx1 += Math.cos(rad1)*accel1;
	vely1 += Math.sin(rad1)*accel1;
	walk1._x += velx1;
	walk1._y += vely1;
	velx1 *= 0.85;
	vely1 *= 0.85;
	//this works out the angle from the CPU to the ball
	radians = Math.atan2((_root.ball._y-_root.walk1._y), (_root.ball._x-_root.walk1._x));
	//this puts it into degrees
	ballDegrees = Math.round(radians*180/Math.PI);
	//when the angle of the CUP to the ball is bigger then it's rotation
	if (ballDegrees>turn1) {
		//it adds 6
		turn1 += 6;
	}
	//when the angle of the CUP to the ball is less then it's rotation
	if (ballDegrees) {
		//it subtracts 6
		turn1 -= 6;
	}
}
