How to find right angle direction from 2 vectors

[AyushRaikar]

how do I find this direction?

[VisAgilis]

Subtract the actor’s location from the target’s. Get the actor’s right vector and compare that with the vector we’ve just created using the delta rotator blueprint node.

[AyushRaikar]

It always points in kind of the same direction

I also tried vector projection but it does the same thing as you said

[ClockworkOcean]

It’s Pythagoras, no?

Or do you just want the normal from the hit face?

[AyushRaikar]

Yes Pythagoras but I want the vector that forms the 90° angle from 2 other vectors

need it to solve a bug in my path-finding system (one actor location and the other is 2nd last path point)

[ClockworkOcean]

But here, it’s just the face normal

[AyushRaikar]

The system finds the obstacles between the path points using a line trace

But it has a bug that the line traces sometimes hit the other actor which is useless as an obstacle

so I hope to find a location a little bit away from the target so the path won’t hit other walls.

I Solved it!
bit anticlimactic for me but it works

It simply rotates the vector by the look at rotation between them.

2mins after finding that I realized I could just not do the final line trace and it worked too (8hs wasted)
