    Hey guys, I'm a bit rusty with my vector math and genuinely lost on something I assumed would be very simple. I have a dot A and a dot B. I want A to point to B and so I thought the math for that was position of B - position of A. But I dunno what that's pointing at...

    I also tried to get B to point to A and that points elsewhere.

    I am working on a Unity 2D project, if that makes any difference. Those dots are sprite renderers, but they're working on object positions so that shouldn't matter imo




    What am I doing wrong here? Or am I just remembering everything wrong?

    The math is sound: (B-A) = direction from A to B
    As Melv said, drawing a Ray is what you want here.

    I know that feeling. On average twice a day. :D
