Ok, I have looked EVERYWHERE and am trying here to simply extract an animation from a .dae imported into Xcode (or a .scn, whatever) so that I can run it on the model throughout my scene kit game. the problem is every way to do this that is referenced (including here Scenekit: Add animation to SCNNode from external Collada)
seems to be deprecated in iOS 11. So I have no way to animate any 3D model I put in my scene.
Right now I am able to display the model just still with this - I get the model from my dae and put it into my blank scn :
if let d = modelScene.rootNode.childNodes.first
{
theDude.node = d
theDude.setupNode() //this scales it down
}
func setupNode()
{
node.scale = SCNVector3(x: modifier, y: modifier, z: modifier)
}
//Then add to scene on tap
let clone = theDude.node.clone()
theDude.node = clone
self.sceneView.scene.rootNode.addChildNode(theDude.node)
theDude.node.position = hitPosition
This works. Trying to get it to run the animation that I added to it in Maya, however, does not. I added these extensions per Apple's example to my project: https://developer.apple.com/library/content/samplecode/Fox/Listings/Swift_Common_SceneKitExtensions_swift.html
And was trying to do this as it says to, just with a cube as a basic test (from the above question):
func addAnim()
{
let characterScene = SCNScene(named: "art.scnassets/cubeAnimatedSkeleton.dae")!
let characterTopLevelNode = characterScene.rootNode.childNodes[0]
sceneView.scene.rootNode.addChildNode(characterTopLevelNode)
let idleAnimation = CAAnimation.animationWithSceneNamed("art.scnassets/cubeAnimatedSkeleton.dae")!
idleAnimation.usesSceneTimeBase = false
idleAnimation.repeatCount = Float.infinity
characterTopLevelNode.addAnimation(idleAnimation, forKey: "idle")
}
But with this CAAnimation.animationWithSceneNamed("art.scnassets/cubeAnimatedSkeleton.dae")! the whole thing does not work because this extension from APPLE:
extension CAAnimation {
class func animationWithSceneNamed(_ name: String) -> CAAnimation? {
var animation: CAAnimation?
if let scene = SCNScene(named: name) {
scene.rootNode.enumerateChildNodes({ (child, stop) in
if child.animationKeys.count > 0 {
animation = child.animation(forKey: child.animationKeys.first!) //ERROR
stop.initialize(to: true)
}
})
}
return animation
}
}
says that addAnimation for key was deprecated in iOS 11. Replacing that with animation = child.animationPlayer(forKey: child.animationKeys.first!) doesn't work, and I don't know what else to do.
What is wrong here?
