mecanim SendMessage bug

public void onWalk(AnimationEvent animationEvent)
{
float param = animationEvent.floatParameter;
}

float param working only.
int and string not working.

That's because it is a stupid unity even, in which it can store one piece of data. You have to handle the events your self.

can't send one string data.
can't send one int data.
can send one float data only.

yes. Don't use mechanim for events. You need to detect events yourself

I think this belongs in the Unity forums? http://forum.unity3d.com/
