How to create a tinsel? - niuage - 06-04-2022
Hi,
I'm probably missing something obvious, but just reading the doc, I can't figure out how to make something similar to a tinsel.
Right now I have a rope attached to 2 points, so far so good, but how can I attach objects to the rope such as they follow it without influencing it, or very little?
Thanks for any pointers.

Hi,
Just use the GetSectionAt(float normalizedCoord) function of ObiPathSmoother. This will give you a full orthonormal frame at any point along the rope, that you can use to place an arbitrary object at.
The normalizedCoord you pass to GetSectionAt() is 0 at the start of the rope and 1 at its end (0.5 would be the middle, etc).
See for the utility script ObiRopeAttach ( found at Obi/Scripts/RopeAndRod/Utils/ObiRopeAttach.cs) for a simple example. This is a script you can place at any object and it will locate it at the given position/orientation along the rope.
Note that using GameObjects for each individual "flag" won't scale past a few dozens of them, so if you plan on having many of these I'd recommend using other (possibly shader-based) approaches.

Well, that's an impressive response speed to say the least
I'll get on that, thanks.
