I’m looking for a way to generate collectable items along a path in my levels. I want the items to be evenly spaced and go around in circles and around smooth curves (a la rings in Sonic the Hedgehog). I could place them all by hand but I wonder that there must be a better way. Can anyone suggest a method for setting a path that I could then generate the collectables along it?
Runtime or edit time? Spline code has been posted to this site a couple of times if you want a do-it-yourself solution. Or you can use iTween with its iTween.PutOnPath() function. iTween is free from the Asset store, and there is also a free path editor that would allow you to quickly lay out the path. And there are commercial spline packages for Unity. SuperSplines has been mentioned positively on this list, though I’ve never used it.
