I was wondering if it is possible to enable gizmos for a debug type mode in a built version of my game.
Gizmos are Editor features only. If you want handles and axes in your game you’ll need to code them.
If you use google (like i did) you should immediately find this post (which is actually a year older than this question):
You also should find this one in the wiki (which seems to be a newer version of the above)
