Normally it is stationary, but I want to create a GameObject called fire that moves when the start button is pressed.

I struck the code while checking various things on the net, but it is exactly the same behavior as before adding the code.
The error is
MissingComponentException: There is no'Animation 'attached to the "fire" game object, but a script is trying to access it.
You probably need to add a Animation to the game object "fire". Or your script needs to check if the component is attached before using it.
Is coming out.

Applicable source code

public void StartButton ()
flag = 1;
timer = 0.0f;
GameObject obj = GameObject.Find ("fire");
Animation anim = obj.GetComponent ();
anim.Play ();
I wrote, but it does not move at all.
