Changing Speed, Animations (Mount)

Hello,

I am trying to add a Mount to my game. (A horse)

At the moment i use the third person script that came with Unity.

When the player presses F, it makes the character inivisible but the controller is still there.

Could anyone tell me how i could change the Speed and animations when you press F?
Change the animations from the man to the horses.

Thanks!

I think you need to give some more info or I am just not understanding fully but you should look into the mechanim tutorials on this site if you haven’t
