Question about making Animation

How would i get my animation to be a file that i can use and watch?

Once you have got it to do everything that you want of it and you can see it all thru your camera (Numpad-Zero) when you hit Alt-A then goto F10 in the Buttons window. In the Output tab set a folder to render to. In the Format tab set a Format (and codec if you decide to use a video format). Then hit the ANIM button in the Anim tab. When it’s finished rendering you can hit Play to play the rendered animation back.
