Crashes with animation overrides in 5.2?

In 5.2 samples from Platformer PRO (an asset of mine) are crashing the editor when they set the animation override. To make it even more confusing its intermittent (sometimes it occurs instantly on setting the animation override, other times after a second or two).

In the times where the bug isn't thrown restoring the original animator has no effect (the overriden animations continue to play).

I'm working on extracting a simple repeatable test case but am wondering if anyone had seen this and had any ideas for resolution (or a repeatable test case and bug number I can reference when I contact Unity support).

Code causing the issue:

Code (csharp):

1.  
2.             if (args.OverrideState != null && animationStateOverrideLookup.ContainsKey(args.OverrideState))
3.             {
4.                 AnimatorStateInfo info = myAnimator.GetCurrentAnimatorStateInfo(0);
5.                 myAnimator.runtimeAnimatorController = animationStateOverrideLookup[args.OverrideState];
6.                 if (state != AnimationState.NONE)
7.                 {
8.                     myAnimator.Play(state.AsString(), 0, info.normalizedTime);
9.                 }
10.             }
11.             else if (args.OverrideState == null)
12.             {
13.                 AnimatorStateInfo info = myAnimator.GetCurrentAnimatorStateInfo(0);
14.                 myAnimator.runtimeAnimatorController = defaultController;
15.                 if (state != AnimationState.NONE)
16.                 {
17.                     myAnimator.Play(state.AsString(), 0, info.normalizedTime);
18.                 }
19.             }
20.  

If I remove the myAnimator.runtimeAnimatorController = lines then everything works fine (minus no animation override).

 

Have the exact same problem.

 

I was running into the same issue and just found a workaround.

Before changing the runtimeAnimatorController just disable the animator, then re-enable it after it is updated.

I.E.

animator.enabled = false;
animator.runtimeAnimatorController = rac;
animator.enabled = true;

Hope this helps

 

Same issue here, unfortunately that solution didn't work for me though.

 

Man, I just spent the last couple of hours trying to find out why the editor was crashing, only to find out that I'm also having this exact same problem. The following line for me crashes the editor:

animator.runtimeAnimatorController = animOverrideController;

Disabling and then enabling doesn't work for me either. @JohnnyA have you filed a bug report yet?

 

Hi all, sorry wasn't watching this thread.

I have not raised a bug as yet, rather busy at the moment. But if no one else has raised one, I'll do so on the weekend when I have some time to create the test case.

Bug was already filed and a fix is already available in the next patch release which should be released this week.

Thanks guys.

 

Thanks @Mecanim.Dev !

 

5.2.1 not fixed.Will fixed in 5.2.1p1 ?

 

I've submitted 2 crashes in one report: Case 726627(nice number ),with reproes for both. One of the crashes is related to assigning an override controller, which doesn't have a controller to override.
Both in 5.2.0p1 and 5.2.1 there is this fix:

• (722058) - Mecanim: Fixed a crash when setting an Override Controller with no controller to override.

However it doesn't fix my crash. Is this the fix @Mecanim.Dev mentioned or is there a 5.2.1p1 coming this week with another fix?

 

@Mecanim.Dev Still happens with the latest patch released today: 5.2.1p1

 

Still Happens in 5.2.1p1.

 

If you can repro the bug in 5.2.1p1, please log another bug with your project, you may have something different in your setup.

 

I just submitted a bug report which includes a simple project which shows the crash when trying to swap animations at runtime using an override controller in 5.2.1p1:

731237

Thanks.

 

Is 5.2.1p2 fixed?

 

Bug is fixed for me in 5.2.1p2

 

We have found two incarnation of the same crash. the first one was fixed in 5.2.1p2 and the second one found by @Korindian was fixed this week so it should be available in the next patch release

 

Thank you.

 

@Mecanim.Dev
5.2.1p3 is not fixed?Please confirm.

 

In 5.2.1p3 aways crash on set runtimeAnimatorController:

This look like another crash, please report a bug

 

@Mecanim.Dev It looks like my bug is still present in 5.2.1p3. I'm guessing it will be in the next patch release this week? Thanks.

 

@Mecanim.Dev Crash still present in 5.2.2 released today. Case 731237

 

Hi Korindian,
the bug is not yet fixed

 

5.2.2p1 still not fiexd.

 

5.2.2p2 still have this problem.

 

Same problem here, related with this : https://issuetracker.unity3d.com/is...which-was-disabled-in-animation-crashes-unity

 

@Mecanim.Dev
Is this bug fixed in 5.2.2p3 ?
https://issuetracker.unity3d.com/is...atorcontroller-while-running-crashes-editor-1
I don't saw any notes about this bug in 5.2.2p3 release notes.And this bug is still exist in unity 5.2.2p2.

 

the bug is not yet fixed in 5.2.x but should be fixed in next 5.3 Beta, so as soon as we get QA approval for this bug it will be backported to 5.2

 

Ok,thanks.

 

@Mecanim.Dev
Why have not been fixed in Unity 5.3 released version?

 

if you still have the same crash in 5.3 then it probably another bug.
please log a bug with your project and we will fix it

 

Just if a GameObject or it's parent is activeSelf=false ,editor will crash when change the runtimeAnimatorController.

 

Reproduced this crash in unity 5.3.0f4, submited a bug with name:
"752642 Unity crashed during creating animator override controller in runtime"

 

Even Unity 5.3.1 and 5.3.1p1,I should to check gameObject is active before change animator override controller.

 

I have to set the current controller to null before applying the override controller:

public Animator animator;

animator.runtimeAnimatorController = null;
animator.runtimeAnimatorController = overrideController;

 

@Mecanim.Dev The issue number 731237 is still present in the latest version 5.3.1p3. It is marked as closed but I test it in every new release and Unity always crashes.

I can confirm the workaround posted by @ephemeral life , that when setting it to null first and then assigning the overrideController, there is no crash.

Other than using the override controller, is there any other way of replacing animation clips at runtime?

 

Found this in patch 5.3.2p2:

• (731237) - Mecanim: Fixed changing Animator.runtimeAnimatorController while running crashes editor.

Just tested it and can confirm that it is indeed fixed. No need for the workaround by assigning to null first. Thank you!

 

Cool. Thanks for sharing.

 

Can confirm another instance - also can confirm the workaround by @ephemeral life works for us too. (Case#768657)

 

Fine.I can change runtimeAnimatorController with gameObject not active without crash.
