I need help using mecanim...

Hi, I'm new to unity, and now I'm trying to make a turret with animation. I just want to play animation whenever user presses SPACE to shoot a bullet. I also want my turret to rotate as I give input through "Horizontal" variable. (Input.GetAxis("Horizontal");)

I already have an animation that I've made with blender.

The thing is that, I can't control rotation of turret while it is playing animation of Idle...

Here, I'm providing my example project here. Could anyone help me out? link text
