如何在iOS场景工具箱中添加自定义动画

Question

I am making a game with scene kit and part of it rolls some dice to generate a number, i have made the dice in 3DS max 2016. I can make the animations easily on 3DS max, but how would i load it into my scene? I have loaded in a dice with no animations, but I am not sure how I can load the dice animations so that it rolls.

What I intend to do is make xcode generate a number, and with that number is chooses a file out of different files, eg animation1, animation2. Say the number generated was 2 it would run animation2.

Thanks

You can export animations from 3DS Max with OpenCOLLADA plugin . Then you can get animations with SCNSceneSource , like:

let src = SCNSceneSource(URL: yourSceneURL, options: nil)
let node = src.entryWithIdentifier("yourNodeID", withClass: SCNNode.self) as SCNNode
let animation = node.entryWithIdentifier("yourAnimationID", withClass: CAAnimation.self) as CAAnimation

Extract animations to array, and attach random one to your node with SCNNode's addAnimation(forKey:)
