Has anyone ever attempted a soccer penalty, shoot out style compatible with Android / IOS? I've seen examples of how to make artillery curve such as in a game like angry birds, which goes across the screen. Yet how could you get a similar effect going up the screen? Any examples or ideas?
Would the game be top-down, or first-person view?
I was hoping first person, yet I would happy with any help as I might be able to adapt it. I was thinking if I can get the ball from a to b with a nice curve I could change the zoom of the ball to simulate distance.
It would definitely be possible. It might need custom movements though, in which case you'd probably want to use some sin() or cos(equations) to take care of the curvature.
But whatever you saw in that artillery example would probably be very relevant. I imagine the movement would still be very much the same, just with different X values.
for a shot that dipped slightly under the middle of the bar, you could probably use the same movement as in the artillery example, but with an X value that never changes. For a shot in the right corner, you might end up using a very similar movement to the artillery movement, where it goes from down to up to down again, and from left to right. For a shot that goes to the right corner, you'd just need to use the same sort of movement, but multiply the X value by -1. And like you say, you'd need to shrink the ball as time went on too.
Also, if the ball moves 1m left at the start of the kick, it will need to move more pixels than if it moves 1m towards the end of the kick (because the camera is closer to the ball at the start of the kick). Getting this right might be tricky, but I'm sure there'd be some tweak that would simulate it nicely. Basically, you'd probably want to reduce the amount of pixel movement, as the animation went on. You'd probably tie this into the same equation you use to shrink the ball, since both would be concerned with the same thing: simulating Z depth.
Though you'd also need to account for the speed of the kick, because a slow shot would still be close to the camera after a few frames, whereas a fast shot might already be at the goals after the same number of frames.
And then you could get all fancy and let a two-finger twist motion add curve to the shot, which would require another set of tweaks to the equation.
It all sounds doable, but there'd definitely be a few factors you'd need to tweak with trial and error.
Thanks for the advice
