GW, AI threw a PLANET!?!? at me?

It instantly changes the orbit, which would be why destroying a halley doesn't affect the orbit.

I don't believe the engine is capable of rendering objects and projectiles on top of another projectile without causing massive lag from physical calculations, but it could be in reach. Perhaps if a planet's orbit was changed to a fraction of what it'll eventually be, allowing a smoother transition.

Does it actually do that? I tried awhile ago and it kept going.

Hmm... what you say is interesting. Do you think this means that the engine already does planetary orbits based upon a physics based system with energy equilibriums and all that?

I'm kinda looking forward to the future to see where these cool derp mechanics might be taken to add more to the coolness factor of PA. Sorry if I misunderstood you at all :/
