still learnin, over here

one quest i have is to create a game where you have a gun or a cannon, and some moving targets in the distance. simple enough. i've seen those tutorials, or ones like it.

but i've never seen a tutorial explain how to animate the actual "bullet" or "canon ball" (or, in my case, we're using chickens as the bullet )

something where you'd actually see the bullet (chicken) getting smaller and smaller and it shoots away from you.

the fun of my game would be in the bullet animation, as well as the target practice.

i was just wondering if there was a reason why that isn't explained much. is it significantly harder? not worth getting into?
