Display potential path to the point

Hey guys!
I want to create an effect, like in any turn based RPG or Strategy, when you are making turn, and selecting the point where to go and see bended line, or points on the screen that visualize how the player would move to that point.
I already have a path to the point, it is an array of vectors from NavMesh. I can use smth like DrawDebugLine - but this is not customizable and visible in Game.

I guess I can use some particle effects, mb Beam, but not sure can the beam be rebuild in the runtime, to properly show the path.

Any ideas how I can do something like in UE4?

Thank you!

You could use the shortest path algorithms Pathfinding - Wikipedia
But I think UE 4 has something built in already, I recommend googling for some tutorials about UE 4 AI.

well, thanks a lot, but if you would read my post you would see that I know how to get path to the point, I even have an array of vectors. So, the only problem is how to visualize that path, with particles or what

I’m sorry, not sure what happened there ;D
You could try to use the emitter, maybe something like this: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

But I guess it depends on what kind of visualisation you want

Most likely yes. I mean, look at the teleporter in the VR template project, they’re using a parabola I believe. You could study that and do something similar I guess.

Thanks again:) Yea, I think some of particles might work fine, the question is - i s that possible to modify that in such way, to be bended according to vector array path to the point. Right now dont see how that is possible((

Hm, and this is the trail! thanks, will take a look now!
