# Rails with randomised planks

I'm trying to generate lots of rails using "animation nodes" and after "googling" I have something like this on the screen. But I have one problem, I don't know how to use more than one object for this crosswise planks.

Right now I have connected "Object Instancer" , how can I add multiple object instancer with random placing of this planks?

In other words I'm looking for a methods to duplicate randomly 3 elements along the curve.

Best!

• Please use the animation-nodes tag for questions related to Animation Nodes. Can you tell me exactly what you expect the output to be? Maybe place some of them by hand so that I can see the result you are after. – Omar Emara Mar 7 '18 at 19:48
• I can't use my computer right now but it's feiry simple to describe. I'm looking for method to duplicate or instance 3 objects along the curve in random order. Right now I have only one plank connected to rails but it's will be cool to use more different shapes of them for more variety look of train rails. Ps. Animation-node tag submitted ;) – Despoa Mar 8 '18 at 8:02
