Mobile game devs, is the animation deciding the results, or is the previously calculated result dictating the animation? (sh.itjust.works)

Dear mobile game devs. When I play games like that, I always wonder if it's the physics engine that's actually random and produces the result?

Or is the result calculated before the animation happens, and dictates the animation?

I've always wondered. I have some notion of programming, but from far back, and I've been scratching my head long enough about this.

Thanks in advance.

In theory, it could do either -- there's no way of knowing from just looking at a screenshot -- but I'd assume that normally, it's simulating the physics and looking at where the ball winds up to determine the score, and that if the physics engine is deterministic, that any variation from launch to launch in a pachinko simulator would come from slightly varying launch speed and angle.

If you can manage to get a ball stuck in a game, or if the game can fire multiple balls simultaneously, then I'd say that'd be consistent with it just simulating the physics and determining the outcome from where the ball winds up.

I don't really know what the benefit to computing a result in advance would be, unless one has a model that optimizes for player engagement or something.

One thing I'd watch out for as a developer is that players might find a setup to get max points every time, so I'd fuzz the plunger input to make it more random.
