[dots] Adding Rootmotion to MyFirstClipExample

I'm trying to get root motion to work with the MyFirstAnimationClip example from the HDRP animation samples repo. Going by how the AnimationControllerGraph & ConfigurableClipGraph demos set up their graphs, I'm making the assumption that all of this is contained to the graph setup(but I'd obviously like to know if this is wrong).

Graph steps:
Add a rootmotion node to graph.
Connect "ClipPlayerNode" to the "RootMotionNode"
Connect "RootMotionNode" to the "EntityNode"
Then copying the same setup as the AnimationControllerGraph, ConvertLTWto4x4Node, ConvertLTWto4x4Node into RootMotionNode etc

With this, the entity moves, but it just goes in a diagonal, and doesn't really appear to be related to root motion of the animation at all.

Here's what the converted entity looks like with the animation looking correct(though no rootmotion) https://i.imgur.com/FprYoZr.gifv

Graph setup code:
(full code, code below starts at ln 147 - https://gist.github.com/thelebaron/7f3a61814fa30dad049d2e7bd969f202 )

Code (CSharp):

1.      
2.  
3. static PlayClipStateComponent CreateGraph(Entity entity, NodeSet set, ref Rig rig, ref PlayClipComponent playClip) {
4. var data = new PlayClipStateComponent
5. {
6.     EntityNode     = set.CreateComponentNode(entity),
7.     DeltaTimeNode  = set.Create<DeltaTimeNode>(),
8.     ClipPlayerNode = set.Create<ClipPlayerNode>(),
9.  
10.     RootMotionNode             = set.Create<RootMotionNode>(),
11.     LocalToWorldToFloat4x4Node = set.Create<ConvertLocalToWorldComponentToFloat4x4Node>(),
12.     Float4x4ToLocalToWorldNode = set.Create<ConvertFloat4x4ToLocalToWorldComponentNode>()
13. };
14.  
15. // Connect kernel ports - TYPE, SOURCE, DESTINATION
16. set.Connect(data.DeltaTimeNode, DeltaTimeNode.KernelPorts.DeltaTime, data.ClipPlayerNode, ClipPlayerNode.KernelPorts.DeltaTime);
17. //set.Connect(data.ClipPlayerNode, ClipPlayerNode.KernelPorts.Output, data.EntityNode); //old
18.  
19. set.Connect(data.ClipPlayerNode, ClipPlayerNode.KernelPorts.Output, data.RootMotionNode, RootMotionNode.KernelPorts.Input);
20. set.Connect(data.RootMotionNode, RootMotionNode.KernelPorts.Output, data.EntityNode);
21.  
22. // Root motion nodes
23. {
24.  
25.     set.Connect(data.EntityNode, data.LocalToWorldToFloat4x4Node,ConvertLocalToWorldComponentToFloat4x4Node.KernelPorts.Input, NodeSet.ConnectionType.Feedback);
26.     set.Connect(data.LocalToWorldToFloat4x4Node, ConvertLocalToWorldComponentToFloat4x4Node.KernelPorts.Output, data.RootMotionNode, RootMotionNode.KernelPorts.PrevRootX);
27.   set.Connect(data.RootMotionNode, RootMotionNode.KernelPorts.RootX, data.Float4x4ToLocalToWorldNode, ConvertFloat4x4ToLocalToWorldComponentNode.KernelPorts.Input);
28.    set.Connect(data.Float4x4ToLocalToWorldNode, ConvertFloat4x4ToLocalToWorldComponentNode.KernelPorts.Output, data.EntityNode);
29. }
30.  
31. // Send messages to set parameters on the ClipPlayerNode
32. set.SetData(data.ClipPlayerNode, ClipPlayerNode.KernelPorts.Speed, 1.0f);
33. set.SendMessage(data.ClipPlayerNode, ClipPlayerNode.SimulationPorts.Configuration, new ClipConfiguration { Mask = ClipConfigurationMask.LoopTime });
34. set.SendMessage(data.ClipPlayerNode, ClipPlayerNode.SimulationPorts.Rig, rig);
35. set.SendMessage(data.ClipPlayerNode, ClipPlayerNode.SimulationPorts.Clip, playClip.IdleClip);
36.  
37. set.SendMessage(data.RootMotionNode, RootMotionNode.SimulationPorts.Rig, rig);
38. set.SendMessage(data.ClipPlayerNode, ClipPlayerNode.SimulationPorts.Rig, rig); // ? do i need this?
39.  
40. return data;
41. }
42.  

 

Am I asking in the wrong forum? Or is the api going to change soon for this particular question?

 

Thanks, I don't suppose there is an eta? I've been using dots since inject so I am comfortable with flux, I just hope that given some of the backlash to packages that rate of public updates hasnt been reduced. Also is this the preferred subforum to talk about dots animation over the dots forum?
