WebJan 31, 2014 · atan2(vector1.y - vector2.y, vector1.x - vector2.x) is the angle between the difference vector (connecting vector2 and vector1) and the x-axis, which is problably not what you meant. The (directed) angle from vector1 to vector2 can be computed as. angle = atan2(vector2.y, vector2.x) - atan2(vector1.y, vector1.x); WebAug 21, 2009 · Add 360° if the answer from atan2 is less than 0°. Which is the same as "just add 2 * PI" if you're having one of those days. Or if you don't like branching, negate the two parameters and add 180° to the answer. (Adding 180° to the return value puts it nicely in the 0-360 range, but flips the angle.
