GameObject won't move when I attach an Animation Controller

When I attach an Animator component to my GameObject in order to animate it, it still moves. However, when I fill in the Controller with my Controller, my object will no longer move. I check, and my rigidbody2D definitely has Velocity, but it isn't moving.

Any ideas as to why this might happen? I'm really at a loss, here.

 

I'm getting a similar issue. The Animator component is causing the Rigidbody2D to not be able to move. Disabling the Animator component shows that the RigidBody2D component should be working otherwise. Collision handled by a Circle Collider 2D component. Willing to share project with Unity devs if requested.

Note: Checking/Unchecking Animator parameters in the inspector while game is running causes physics to work as desired. Won't work as desired on startup however.

 

Zerotri3, that sounds exactly like the issue I'm having. The weird thing is that I don't get this issue on my other objects, which seem to be set up in the exact same way, just this particular one.

I've also disabled my CircleCollider2D, which does not seem to make a difference.

Also of note that if I have an Animator component but do not apply an AnimationController to that Animator, it will still be able to move.

 

I still haven't got a clue what the issue here is. Anyone?

 

Sorry to keep bumping this, but I need to get this figured out. I started a blank unity project and made an animation. When I try to animate, I cannot alter the velocity of the rigidbody2D directly. This is a major problem. I need to be able to do this.

 

Hey DanPHernbrott,

After getting myself a little more acquainted with Unity I came back to try and determine the problem and it was rather embarrassing.
It turns out that the animation I was applying to the object was actually modifying the transform of itself (though constantly back to the same value), rather than its child objects. This was causing any sort of forces applied to be ignored.

Hope this helps,

Ok I Figured out what is happening here. and how to Fix It! The problem is, when you are making an animation, if you move the root game object, rather than the actual sprite body parts inside the root object, then what ever parameter you changed gets locked.

I did it for a Death Animation, where i grabbed the whole object hierarchy and moved it, and rotated it. So then the character couldn't move. I removed the position change on the root object in the Animation tab, then my character could move again. Yay! But they where walking backwards, only facing one way.

this was because i had used the rotate in the animation, and was using transform.eulersAngles.y = 180; to flip the character back and forth. This is essentially the same as rotation, so it was locked as well.

I removed all the animation keys that were changing the root object, and redid them on the body parts instead, and everything started working fine again. Thanks for the tip Wynter Woods, it was invaluable.
hopefully, my reply can help someone as well

 

This really sucks for people who build their entire animations with the unity animation engine itself. like for UI elements for example which pretty much NEED to be animated in unity if you are using Ugui. What you are saying is that these people have to redo their entire animations to fix this problem simply because their animator was automatically created on the wrong gameobject!?

 

If you want to be able to change the that stuff, you'll have to create state machine behaviors, and script changes to velocity, angular rotation velocity, or cancel it whatever. Sometimes you have to turn apply root transform off in the script when you enter the state as it will completely nullify the animation or cause adverse effects.

This is related to what kuom said as well.

 

ohhh.... this is some old thread, probably no one will ever read this:
,But I fixed it, the point is that even if you have 100 animations, even if one of them is changing the position, you cant change it during gameplay, I have a death animation to raise the body, but it made all of the other animations not work, so removing it made everything better again.

What you can do, is put your player in an empty game object, and change the position of the player with animation, but you will change the empty game object via code. this solved the issue

 

You need to Bake Into Pose the animations Root Transform Position. You can do this from the animation properties in the Inspector !!

 

Try to check "Apply Root Motion" in Animator properties

 

I experienced an issue like this when I tried to bring a prefab into a new scene. The player could move around in the original scene, but not when I tried to instantiate it in a new one.

Following what was said above, I found an unwanted position keyframe in the Animation tab, which conflicted with the movement. I deleted it, and it worked as expected. I wouldn't have expected this because nothing was recording.

 

STILL IM FINDING THIS ISSUE

 

DID YOU FIND ANY ANSWER FOR THIS?

 

Apply Root Motion worked for us.

 

here i am giving you the solution , First make an empty game object , then add the player sprite as a child .
Add all the rigidbodies and the Box colliders to the empty game object .Also add the player control script to the empty game object
now run the animation , will solve your problem

 

SOLVED:
I found that an animator component was attached to a child. I removed it because root already has the component. And it fixed the issue where when you change the child, the position of the root also changes, resulting in rigidbody not working (or technically fixed rigidbody position).

 

Hi all. This was plauging me for months but I found the solution at least for me. I needed to add an additional layer / gameobject inbetween my root object and the root of the rig . Note* I'm not using Apply Root Motion on either

so before I had:

Player (root gameObject with most of the scripts)
Armature (just an empty gameObject)
{ Pelvis
Skinned Mesh as sibling of the Pelvis }


After adding the extra layer and it all working:

Player (root gameObject with most of the scripts)
Dummy Root Object (another empty gameObject)
Armature (just an empty gameObject)
{ Pelvis
Skinned Mesh as sibling of the Pelvis }

Hope this helps.. Such an easy fix but caused me months of frustration.

 

I fix this problem by checking the box "Apply Root Motion " on the Animator component.

 

Did you check "apply root motion"?

 

I had this same issue along with everyone else. I tried multiple solutions, ranging from placing the animator on a child gameobject, placing the sprite renderer on a child gameobject, selecting apply root motion, deselecting apply root motion. Fiddling with animations, ensuring they aren't altering the primary gameobject position, but the bone's position. All kinds of stuff.

What I believe worked for me, because I finally got it to work. I changed the component order of my primary player gameobject. And I deselected apply root motion, and Ensured I only had 1 animator on the primary gameobj, not 2 (one on primary and child gameobj).

Component Order

Gizmo (Primary Player GameObj)
- Sprite Renderer
- Rigidbody 2D
- Capsule Collider
- Player Movement Script
- Animator
- Sprite Skin

GameObject Hierarchy, including child gameobjects

Gizmo (Primary Player GameObj)
- Body (Skeletal System)
- GroundTransform (checks for ground)
- WallTransform (checks for wall)

 

i am happy this thread exists tho. how is one supposed to know that an animation can keep your gameObject from moving?! so thanks for sharing this, even though you thought know on is going to read this

 

Thanks Man

 

THIS WORK ON ME

 

For me when i attach the animator controller into the player that was moving right it stop moving reading some comments made me realize i may changed the transform of the player in some animations i deleted the ones that i though they were suspicious and it worked.

 

I am not sure I am facing the same issue. I have a parent object and two children. The parent has an Animator that moves the 2 children based on triggers (2D). I works fine. Now I need to move the same objects without animation in some cases. If I simply do it on script, nothing happens. If I disable the animator, the script can move them. Apply root motion does not change this behavior.
Someone mentioned in this thread that it is not possible to do it and I am inclined to believe it.

 

I just found the answer for my issue: https://stackoverflow.com/questions...bject-setactive-if-there-is-an-animation-that

 

Still havent found a working answer

 

This Actually Fix It!!! The easiest way, Thank you!
