Correct Animation Plays Only On First Instance

Guys, I'm working on a VR game, and I am having issues with animations. I have some enemies that are activated once my player gets within a certain range of them. For some reason, the correct animation only plays on the first one that is activated. The idle animation plays on the others. I have a bool set up in the animator to set to true if the object is moving. I used Behaviour Designer to do the movement stuff, but I don't "think" it has anything to do with this issue. For some reason, the animator is only "initialized" on the first enemy activated.

The Enemies are instantiated when the scene loads, and I have the character in an empty game object, and also have moved the animator to the empty game object too, so that it already exists before the character is enabled, but still get the same behavior.

Any ideas?

 

I have the exact same problem.

I made a prefab for a npc that uses script for AI and setting animation boolean variables, and a Animator Controller for running animations based on the bools inside. It's working like a charm for the first instance.
But every other instance of the npc is stuck on a permanent idle loop (the entry animation).

On further tests, it seems that if I set the animator booleans to other values from the editor, animations will trigger correctly. This means that the booleans are actually not getting changed within the script.

Immediately I thought it's a issue with the way I retrieve the animator instance in the script, but testing showed that is working well. Each NPC's animator returns a different instanceID.

More tests, and it looks like the booleans are set corectly at runtime, but the animator does not react to them.

To summarize, setting the bool variables in editor before starting game, makes the animator switch animations correctly. But setting the bool variables at runtime works only for the first instance of the prefab, and for the rest the animator ignores them and acts as if they are still at default values.

It looks to me like a unity engine bug. Anyone have further insight into this ? It's a pretty big issue front and center which should affect just about everyone, so I can't shake the feeling I must be missing something.

To get the animator instance I tried these 2 ways, both work.

Code (csharp):

1. anim = GetComponent<Animator>();
2. anim = this.GetComponent(typeof(Animator)) as Animator;

To change the active animation I use:

Code (csharp):

1. void SetRunning()
2.     {
3.         anim.SetBool("isRunning", true);
4.         anim.SetBool("isIdle", false);
5.         anim.SetBool("isAttacking", false);
6.     }
7.  
8. void SetIdle()
9.     {
10.         anim.SetBool("isRunning", false);
11.         anim.SetBool("isIdle", true);
12.         anim.SetBool("isAttacking", false);
13.     }

 

Hey siskyn,
I never figured it out. There were a few fixes here on the forums, but none of them worked for me. Really frustrating! Was really excited about my game, but killing a month of my spare time jacking with stuff like this sure takes the excitement out of it. LOL. Haven't got back to it for a while now. Good luck to you, and if you get it, please let me know!

 

I found not so much a fix, as a work-around.

Turns out, that the NPCs get bugged if they are instantiated from the editor.
However, if they are instantiated at runtime, they work correctly.

So, if you need a fixed number of NPCs at certain locations to spawn, simply place empty game objects at that location, and use them as spawn points in a spawn manager script. Similar to how you would create infinite NPCs from fixed spawn points as done in the Survival Shooter Tutorial - 9 of 10 : Spawning Enemies - Unity Official Tutorial.

Edit: Gah. It turns out that animations break when having more than 3-4 instances. I wonder if this is a intentional limitation of free unity.

 

No sir, never filed a bug. There are several post with people having the same issue, and several solutions. Just never got any of them working for me. Figured it is just something I'm doing wrong since I'm a newbie.

 

Hello guys,

Any answers for this subject yet? I`m having the same problem
