I’m messing with procedural mesh generation (see the wiki page I wrote: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums). In my example, I’m using a lathe algorithm to spin a polyline. I’d like the user to be able to modify that polyline and see the result directly. I was wondering if there were some useful bits in your code that I could reuse to draw handles and such in-game, or is it too tied to the Editor itself?

The way I’m drawing handles is with my USTRUCT

if you look in the source code I define a simple button USTRUCT (VictoryEdEngine.h)

and I create an array of these for all the key points I want the user to interact with.

Then I run a function to check if the cursor is in one of these buttons (2D canvas space).

The Button itself stores a variable for its 3D Vector counterpart.

If you can figure out where the points are in 3D space then you can use, my user interfacecode to create points the user can click and drag around is quite simple to re-implement anywhere you want.

To put it in perspective, I originally implemented this system in the HUD class for an in-game case

Hee hee!
