Question

Basically I have two 2D points and there is a line between them. A cube is placed on the midpoint of this line. I want the cube to rotate so it is facing upwards from the line as the diagram below indicates.

I’ve been thinking through how I can do this using trig and I still haven’t come up with anything. Any ideas would be much appreciated 🙂

Answer 1

In pseudo-code:

angle = atan2(p2.y - p1.y, p2.x - p1.x)

cube.rotation = angle + PI/2
