Unable to play animation from another layer

[jfrierso]

I’m attempting to play an animation from different layers but having some difficulty. I’m trying to play animation transitions in one layer and then go back to the base layer to play an animation after the transition is completed. However, the animation in the base layer isn’t playing. Here’s a sample of the code:

 private IEnumerator MyFunc1(Animator animator)
{
  animator.enabled = true;
  animator.SetLayerWeight(7, 1f);
  animator.SetBool("isJumpingFromSitting", true);

}


StartCoroutine(MyFunc1(Player_animator);


m_Player1.GetComponent<Animator>().enabled = true;
m_Player1.GetComponent<Animator>().SetLayerWeight(0, 1f);
m_Player1.GetComponent<Animator>().Play("Clapping");

Help is appreciated.

Here’s a sample of the code:

Anything with Animations / Animators / Mechanim:

Only consider the code AFTER you have done this critical step:

Always start with the Animator state machine and prove it works in isolation, no code at all.

Here’s more reading:

Press keyboard key to play animation using different animations per assigned key

With animation always start with the animator / animation setup itself. You can clear the scene, pull in the animated object, then while the game is running, use the Animator window to wiggle all the properties to make sure it does what you want when you set it. If you can’t get it to work by hand-setting the properties, nothing you do in code will matter, obviously. Usually for one-shot things like a dance you use .SetTrigger, not .SetBool… then mark the dance animation to cleanly exit on it…

Hi Kurt,

Thanks for the reply. It’s appreciated. The animations work without code as viewed in the Inspector’s Preview of the transition. I’ve attached a screenshot of the Animation previous in the Inspection view as well as the triggers in the Animator Controller.

After switching from Boolean parameters to Trigger, the result was the same. The subsequent animation that is to play, does not. However, when stepping through code, when the triggers are called, execution is immediately returned back to the place that called the function (MyFunc1 in the sample code) rather than completing operation in the coroutine before returning the code that initially invoked the function.

[Kurt-Dekker]

The coroutine in the snippet above does not have a yield. I understand perhaps you shortened it for posting? Without a yield the code would not even compile.

Otherwise there’s an animator obtained from m_Player1.GetComponent<T>() and one passed in.

Generally you want to avoid using GetComponent() except where there is no other choice.

Are those the same animator? Are you sure m_Player1 is actually the player IN your scene and not a reference to the prefab? If it’s the prefab, all bets are off as that’s just the file on disk.

Simply Instantiate-ing a Prefab does nothing to the prefab. It’s still a file on disk, unchanged. See below.

Here’s some more about names like m_Player1 and the problems the might cause:

Instancing and prefabs in Unity and naming your variables:

If you name your public / serialized fields (variables) as simply “thing” then you set yourself up for confusion.

If something is a prefab, name it that, such as public GameObject ThingPrefab; and only drag prefabs into it. Prefabs are “dead things (assets on disk) waiting to be Instantiated.”

If something is already in the scene or you Instantiate<T>(); it in code, then store the result in a properly-named variable such as private GameObject ThingInstance;

Naming is hard… name things WELL to reduce your own confusion and wasted time.

The code wouldn’t compile if the yield wasn’t included. So, yes, it was left out for brevity. As mentioned in the initial post, the transitions work fine, so the prefabs that are instantiated for the GameObjects, m_Player1 and m_Player2 are fine, as well. All operations for these objects work except for the animation that is called after the coroutine. That is, if the coroutine is skipped or not called, the animations that follows the coroutine runs fine in the code.

Also, we’re unable to play the same transitions, consecutively. That is, after the 1st call to animation transition in another layer, all subsequent calls will not play. It appears that the maybe the parameters are resetting or there maybe some interference with the layer? Could this be related to initial issue or question in this post?

Help is appreciated.

Could this be related t

Great question! Find out by debugging.

By debugging you can find out exactly what your program is doing so you can fix it.

Unity - Manual: Debug C# code in Unity

Use the above techniques to get the information you need in order to reason about what the problem is.

You can also use Debug.Log(...); statements to find out if any of your code is even running. Don’t assume it is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.

It appears that you really have nothing to add, so gonna have to ignore your responses, henceforth. There’s nothing edifying in them, so it makes them insipid and not worth reading.

We’re able to play animations in the Base Layer after playing animation transitions in other layers by syncing the animation transition or layers w/ the Base Layer (see attached screenshot). However, the animation transitions now play too fast. We’ve tried slowing down the speed of the animation clips in each transition but no avail. Also, tried Addictive Blending, so that the speed settings would not be overridden and that didn’t work, either.

Help is appreciated.
