[SOLVED] Line Trace points somewhere else

Development Programming & Scripting
1

Hi!

I am using LineTrace for the first time. My goal is to use it in a VR gaze-based teleport system. I followed some tutorial I found online and after some issues with the results decided to go to the basics by applying it to the FP-Character of the FPTemplate. I did what the turorial said as you can see in the picture here:

But when I hit on play and click the fire button the trace line is drawn pointing to the sky and backwards when I am aiming at at box. I think it has to do with the Get World Position node but I cant figure out how to solve it.
I know this is pretty basic stuff but I cant find the solution online.

Thanks!

Hi

I think you have to use multiply on the forward vector instead of your add 1000. And also change the vector multiply vector to vector add vector.

You have trace done not correct. Here how to (you need to change Event Tick with Fire if you need):

you have + and multiply in wrong places - change it. fps camera/GetWorldLocation must be vector + vector, GetForwardVector must be vector * float (or integer).

Amazing! That was it! Thanks! So silly not to see that.

This can be confusing, good it works. Select answer to close thread - title not closing it.
