I would like to have a game where you draw a curved trail and an object follows it. The drawn line should be visible. While drawing I would like to put down keypoints and then having the object move steadily towards them - much like you can see here when you are dragging the little workers here. I would like to make a similar controls for a different game but using Unreal engine and I just can’t figure out what to do. Can you point me out to some tutorial or topics I can check?
It does not matter wheter it would be a blueprint or code.
I think the easiest way for making drawing in 3D space is by using Spline Component
And looking on APIs you can create waypointing using it which let you make object follow the trail
