Mecanim "Set Animator Look At" can't work in Unity5

(1/6) > >>

Hayato:
Hello I'm using  Mecanim Animator actions in unity 5 and find the "Set Animator Look At" Action can't work.
It got warning massage below:


--- Code: ---Setting and getting IK Goals should only be done in OnAnimatorIK or OnStateIK
UnityEngine.Animator:GetIKRotation(AvatarIKGoal)
HutongGames.PlayMaker.Actions.GetAnimatorIKGoal:DoGetIKGoal() (at Assets/PlayMaker Animator/Actions/GetAnimatorIKGoal.cs:109)
HutongGames.PlayMaker.Actions.GetAnimatorIKGoal:OnUpdate() (at Assets/PlayMaker Animator/Actions/GetAnimatorIKGoal.cs:95)
HutongGames.PlayMaker.FsmState:OnUpdate()
HutongGames.PlayMaker.Fsm:UpdateState(FsmState)
HutongGames.PlayMaker.Fsm:Update()
PlayMakerFSM:Update()

--- End code ---

The Animator IK Proxy has added and other IK actions like "SetAnimatorIKGoal" can work well.
How can I fix it ?

*Using playmaker 1.7.8.3  and Unity 5.0.0 Mecanim Actions in Unity 5.0.1f1 (https://hutonggames.fogbugz.com/default.asp?W1031)

Bump.

I've just updated Animator Actions to Unity 5 and I'm getting same problem.

jeanfabre:
Hi,

It's ok, this works anyway. You can ignore this warning.

 It's because you need to drop the IKAnimator proxy, the action detects it automatically. I'll update this so that it's more obvious. I'll push a sample on the ecosystem.

 Bye,

 Jean

Hayato:
Thank you for reply my question.
I have drop the PlayMakerAnimatorIKProxy component into the humanoid charactor.
And can see the "Set Animator IK Goal" work well.
But the "Set Animator Look At" seem didn't work at the same charactor.
Do I miss anything or just use the action in a wrong way ?

I take a screenshot for it.

Hayato:
[Solved!]

I compare the "SetAnimatorIKGoal.cs" and "SetAnimatorLookAt.cs" files.
And found that SetAnimatorIKGoal have change to use "PlayMakerAnimatorIKProxy" component ,but SetAnimatorLookAt Action still use a old "PlayMakerAnimatorMoveProxy" component .
So I try to exchange some words in SetAnimatorLookAt.cs base on the SetAnimatorIKGoal.cs , somthing like :

--- Code: ---PlayMakerAnimatorMoveProxy --> PlayMakerAnimatorIKProxy
--- End code ---
and

--- Code: ---public void OnAnimatorMoveEvent() --> public void OnAnimatorIKEvent(int layer)
--- End code ---

Finally it works well now :)

The modified "SetAnimatorLookAt.cs" as below :
