Hi!  
I don’t understand what the problem could be. Because of different software versions?

fmod version 2.02.20  
Visial studio 1.85.2  
unity 2021.3.9

I can’t connect steps because of Eventref

Hi,

`[FMODUnity.EventRef]` is obsolete, please use `public FMODUnity.EventReference` or run our [Event Reference Updater](https://fmod.com/docs/2.02/unity/tools.html#event-reference-updater) tool which will change these for you.

Hope this helps

Hello!  
I updated fmod and it found the error, but when I deleted {footstepevent} in code nothing happened. I dont understand what the problem…

Hi,

Could you try adding a variable name on line `7`? e.g.

```auto
public FMODUnity.EventReference variableName

```

I have not seen this error before:

Is this a result of running the event reference updater?

I updated FMOD and now he writes me this : ‘Player’ AnimationEvent ‘footstepsevent’ on animation ‘Run’ has no receiver! Are you missing a component?
