    There is no remove event function however it is possible to set/get the events with animationClip.events. So call the get, remove it from the array and then call the set.

    then i create animation, and set this in Update:
    Code (CSharp):
    1.         if (isMoving == false) {
    2.             GetComponent<Animator> ().speed = 0;
    3.            
    4.         } else {
    5.             GetComponent<Animator> ().speed = 1;
    6.         }

    @karl.jones I've been trying to put together a worked example of what you are suggesting but I've run into something of a roadblock with unity crashing intermittently and not being able to iterate over the events array returned from the get...

    <snip, whole bunch of not relevant stuff>


    also getting some very bizarre crashes but I think that's "me" rather than a problem with the script/setup... could someone else run the test and see if it works (in which case it's all "just me" lol o_O )

    Seems like the event array contains null objects.

    yeah, but there are definately 5 events doing something because the functions are being called and the debugs are coming out o_O

    edit: still get the null exception even if I take out the parameter bit, just looking for functionName,

    that should be able to output 4 "SendSomethingToLog" and 1 "RemoveEvents" :(

    Can you upload your project or a simplified version? I can check if its a bug or something with your project.

    Everything works for me.

    In fact I got events removing with this quick hack

    Code (csharp):
    1.  
    2. public void RemoveEvents()
    3. {
    4.     AnimatorClipInfo[] myClipInfos = anim.GetCurrentAnimatorClipInfo(0);
    5.     AnimationClip myCurrentClip = myClipInfos[0].clip;
    6.     AnimationEvent[] myEvents = myCurrentClip.events;
    7.     Debug.Log(myEvents.Length);
    8.  
    9.     if (myEvents.Length > 0)
    10.     {
    11.         var list = myEvents.ToList();
    12.         list.RemoveAt(0);
    13.         myCurrentClip.events = list.ToArray();
    14.     }
    15. }
    16.  
    What version of Unity are you using?

    Can you upgrade to 5.0.2f1, there is a fix you need.

    • Mecanim: Fixed crash when calling AnimationClip.events from script.

    Since there is still no removal method, setting the event array to zero works fine.

    Code (CSharp):
    1. animationClip.events = new AnimationEvent[0];
