Problem with object reference in animation events

Hi Peter, 

Thank you for your quick response. I'm really glad that you have this in your plans, cause Umotion is a hell of a tool, and I love it! 

As for the workaround, our programmers could think something out, and fix it if you would show them the class where to do it;)

Best regards,

Kacper

Hi Kacper,

thanks for the kind words. I'm glad to hear that you enjoy working with UMotion.

As for the workaround, our programmers could think something out, and fix it if you would show them the class where to do it;)

There are several things you could do as a workaround:

1. Avoid using object references by replacing them with strings/names or by having the references stored in a MonoBehaviour (Inspector fields) and referencing them via indices in your events.
2. Write a custom UMotion export script that preserves the object references already stored in the animation events:

using UnityEngine;
using UnityEditor;
using UMotionEditor.API;

[InitializeOnLoad]
public class UMotionExtensions
{
   static UMotionExtensions()
   {
      ClipEditor.AddMenuItem(ClipEditor.MenuCategory.File, "Custom Export", MyMenuItemPressed);
   }
   
   private static void MyMenuItemPressed()
   {
      // Reference the *.anim file your export is going to overwrite e.g. by searching for a file with the same name as the current UMotion clip (use ClipEditor.GetSelectedClipName();)
      // Use AnimationUtility.GetAnimationEvents() to get current anim event data of *.anim file
      ClipEditor.ExportCurrentClip(); // Now UMotion exports the clip and overrides the *.anim file
      // Use AnimationUtility.SetAnimationEvents() to replace the anim event data with the original anim event data
   }
}

Please let me know in case you have any follow-up questions.
