The first input for the dot product is the direction that the guard is facing, the second input is the vector from the guard's position to the ninja's position. Then we compare the cosine of the angle formed by those two vector with the cosine of half the FOV: | The first input for the dot product is the direction that the guard is facing, the second input is the vector from the guard's position to the ninja's position.
