How do I make an animation play?

Questions & Answers

I have been using a non-animated model in my game but my animator sent me a version of my character with a running animation. After importing this and running the game, I can see the run animation play on model (nested inside a ‘Player’ GameObject) but when I remove that animation and insert the animation onto the top-level ‘Player’ object (in order for it to be controlled by Player Animation script) it no longer seems to play. Why is this?

Here is the code :

 void Start()
 {
     animation["AnimationName"].speed = 1;
     animation.CrossFade("AnimationName");
     animation["AnimationName"].wrapMode = WrapMode.Once;
 }

in further you want to use it means use boolean variable, whenever it’ll true play the animation.
otherwise you can use

animation.Play("AnimationName");
