Get angle offset from forward vector (Need Help)

[AltairGamesLLC]

I tried to use the last chart. But it didn't work for me. I have a player and a horse. I create a sphere trace to detect the horse. I'm trying to find out if the player is standing on front/left/right/rear of the horse so that I can play certain mounting animation.

Well ... For me the Z value of vector is always 0 (the one before Sign) but when I do not split structure and display it -> It has -0.000 or 0.000 ... what the heck is going on?

Old post but seen a couple of people afterwards having trouble...

For anyone else getting this issue, you might be confusing "Cross Product" with "Vector * Vector", make sure you search for "Cross Product" just before the "Sign (float)"and it should work for you.
