Can't move gameobject after timeline completes

I'm not sure if I'm missing something here, but it seems that if you have a custom animator controller on a gameobject, put that gameobject into a timeline and attempt to move its position using the timeline; the object will be unmovable once the timeline completes.

I've tested this with a brand new project, using a gameobject that only has a sprite renderer an animator and a custom anim controller that only consists of a single sprite. I test if the object can move by attempting to change its transform position in the scene after the timeline completes.

If I disable and re-enable the "Animator" component, the object will be movable again. Also if I clear the "Animator->Controller" field for "None (Runtime Animator Controller)" this issue does not occur

Does anyone know why this would be happening? It's a big issue for me since I want to move my playable characters position in a timeline, and continue controlling it after the cinematic.

This is in a 2d project

 

Hi,
When you say unmovable, you mean that it wont budge at all or that it is reset to it's position?
A small clip might help to understand the issue.

 

Sure, I'll post a clip when I'm back at my computer tonight.

For now when I say unmoveable, I mean it resets its position if you try to move it. For instance, if you click on the game object in the editor, type in a new X value to the transform.position and press enter; it will immediately reset the position to where it was.

If I enable / disable my animator at this point and try the same test, then the gameobject will properly move to my defined value

 

Here's a clip of what I'm seeing. The square is being moved from left to right using a timeline. Once the timeline has finished. I cannot change the squares position unless i disable and re-enable the animator

 

Interesting, I wasn't able to repro here unfortunately, if you can open a bug with the attached project and post the bugid here, I will be able to track it down

sorry about that

 

I created a bug report for this and uploaded the project twice today. Each time I got a notification saying that "It was successfully uploaded and should receive an email shortly". However after waiting all day, I haven't gotten an email from either attempt.

Maybe you can find it in the backend?

 

Hi, I'm also experiencing this bug but can't find it in the issue tracker. It's like the animation clip that I have on my timeline doesn't clear it's bindings properly and therefore is constantly setting the game objects position.

 

I tested in a similar scene to Greg and can recreate this. Not sure if this is the same as Greg's issue but if you:
-Add cube to scene,
-create playdirector and animator using the button in timeline,
-Add animation track, assign cube and add a couple of movement keyframes.
-Play anim, cube moves and when finished cube can be moved - this all works fine.

To break it:-
-Add a separate animator controller and assign it to the cube's controller
-Play anim and when finished cube cannot be moved

So I think it's to do with having 2 different animatorcontrollers. We ended up caching the runtimeanimatorcontroller and setting it to null. Then in the animator stopped callback we reassign it to the cached controller and all seems to be back to normal. Hope that helps.

 

Thanks for the reply dandawes, that's the exact issue i'm seeing. If the animator controller is empty, this issue does not occur. If I have an animator controller assigned, then the gameobject cannot be moved after the timeline sequence completes.

Caching and re-assigning the controller is what crossed my mind for fixing this too, but it sounds like a work around to a bug in the timeline feature.

I've been emailing back and forth with unity's bug team in attempt for them to see why this is bad... but so far no luck. The issue id I opened is 1118708, but apparently it can't go public until their QA team acknowledges it as an issue

Just to re-iterate what the issue is here:
A timeline that is no longer playing should not override the position of a gameobject that is using an animator controller.

 

That's great to hear, thanks everyone for the help!

 

Hi, I am still experiencing this issue in 2019.1f
Any updates on this?

Can confirm that by reactivating the animation on the object "releases" the object again.

 

So unless you we use root motion , timeline will keep affecting the position of the object? Is there anyway of fixing it for non root motion? my character dynamically switches from gameplay to cutscene and from cutscene to gameplay. but when ever i disable root motion for technical purposes(air brake) my character teleports to the cutscene's origin position. I tried disabling and enabling animator but that only works if i manually do it and not via script. What do you suggest i do?

 

The air brake isnt really a animation and i disable rootmotion even when falling. how do you suggest i bypass this then? Also note i get rid of the player's animator reference in timeline immediately after the cutscene stops

 

Forgot to notify , I fixed it by making runtime animator controller null and in the second line i assigned the animator controller again.
The airbrake was not part of the time line it was used for dev testing.

 

Thanks @Meheraj7 , I stumbled upon this bug as well and reassigning the runtime animator controller worked.

 

this BUG should be fixed

 

How did you reassign the runtime animator controller? Did you use a Signal in the timeline that calls a function like this?

Code (CSharp):

1.  
2. public RuntimeAnimatorController animController;
3.  
4. public void ResetAnimator()
5. {
6.         anim.runtimeAnimatorController = null;
7.         anim.runtimeAnimatorController = animController;
8. }
9.  

Genuinely curious, I'm having this exact problem but can't seem to be able to fix it.


EDIT: Found the solution. Apparently if we use a Signal to call a function that will reassign the runtime animator controller it won't work. Instead, I had to reset the animator after the Timeline animation ended, with an Invoke or a iEnumerator.

 

The way I do it is
When I play the cutscene I do a unscaled time invoke with the duration of the cutscene. when the invoke function plays I stop the cutscene and reassign the animator in the line after

 

Does anyone know how I can move the object without adding an ANimator to it?
In my case, I want to move the Player up some stairs as an "cutscene" - BUT - the animator controller on my Player is set as a Child. So if I add this animator to the Time line, the player won't actually move to the top of the stairs when the timeline is finished (since all his properties are inside the main object)
I can solve this by adding an Animator to the main-object, but that messes up the AnimatorController inside the child.
Difficult to explain but...
Basically I want to move the Main Player object inside the Timeline, but it seems like I have to have an Animator attached to it.,

 

Thanks for the advice but seem to be same problem. It adds an animator to the Player... and that Animator interferes with the animator inside the child :S

 

I have a problem similiar to this. I made a timeline and an animation but now can't move my character. Only way to make my Character move is by disabling the animator on the Character.

 

Was struggling with this, found a work around for my particular case, maybe this can help someone.

If you're using an Animator component and animation controller, any state in that controller which references an animation that key frames a change in a transforms position will override any future changes to it's position - even when the animator is not in that state (and thus one would expect to be able to move it freely). Not sure if this is a bug or intended, toggling "Write Defaults" in the state doesn't seem to help. Interestingly if the transform is key framed but doesn't actually change its position (example: uses 2 key frames of the exact same position) the position locking problem will not occur.

I have a transform that I want to move freely (using a rigidbody), but I also want it's position to be controlled during one of my animations. My workaround to achieve this was to remove it's state from the animation controller, switch inspector to debug to mark the animation as legacy, and play that particular animation from an Animation component instead of from the Animator. This solved my problem - the transform with rigidbody moves freely except for when the animation is playing in which case the position is overridden and controlled by the animation key frames.

 

I solved the problem by setting Animation Culling Mode to Update Transforms and unchecking the loop time from the animation window hope this helps

 

Can someone help me. I am on 2021.2.4f1 version and I suddenly got this issue. I was working on a cinematic like I have done before without a problem. After making the cinematic when the game should go back to gameplay my character stopped moving. The only different thing i did was I used override track this time. I have to fix it as soon as possible. I have tried reassigning RuntimeAnimatorController using the code above but it doesnt work.. When I enable root motion on my animator the character does move (even though my character doesnt move on root motion) but then other things break like physics collision test. Can someone please tell me a way to fix this without losing my project

 

I have a related and simple issue where I can't move a gameobject after a clip that was controlling it completes, but the timeline is still running.

I have a clip that moves the camera from A to B from 0seconds to 20seconds, after 20 seconds I activate a script on the camera that makes it follow the player. However I can't find a way to make the first clip stop controlling the camera, even though the play head is after the clip itself and the extrapolate is set to none. Blending is not an option either as the are two different things that just happen to control the camera.
