Does the gravity generated in the game by the game engine affect things like missiles and shots?

Not that I've noticed, but it's very easy to test. Make a spöb with a very strong gravity well, make a very slow weapon, and fire it near the spöb. If it's pulled toward the spöb, then gravity affects weapons.

I'm 99% sure they aren't; that would take a ton more physics calculations than are done already.

It would?

Going by some back-of-envelope calculations, it would be very simple to model the effect of gravity on projectiles - the inverse square distance from the projectiles to the spöb in question, multiplied by a constant for the strength of the spöb's gravity and with some direction injected. With a bit of SSE vectorisation squirted in there for good measure, I make that 20 instructions for the gravity calculations.

Hardly a huge investment.

Oh. Eheh...

...All right. That's cool.

Did we ever get an answer to this question? It'd be useful knowledge.

I believe Jacabyte said that it was 99% chance they weren't, but I'll eventually test this, since it would be interesting in Airborne, given wind currents and such.
