If by flat you mean non-curved, then no. I plan to add a very slight tilt to terrain based on distance to camera, to create a horizon. This means my sky box won't need "artificial mountains in the distance", you'll be able to see a mountain/tower/stuff rise over the horizon. The circumference won't be as large as that of the real earth, but large enough to give you the idea of a huge world instead of walking over a really small asteroid. I don't intend for the terrain to wrap around, it's just a trick to make stuff look better.

If two players start a fight in the middle of a town square, and everyone around them is forced to slow-motion, that's griefing waiting to happen.

I didn't read your whole post, but to solve this issue,
 just put a limit on the number of people to be allowed into a simultaneous bullet time.
That way, if you are in a crowd of six or more people,
 bullet time is not allowed.
Maybe in addition you can add an option to start a "group bullet time" where if enough of the surrounding people opt in, (at least 2/5's of them) you can do bullet time LOS again.

Screw the terrain being realistic for now.

Too hard to do right now, and thinking = no progress. Implement basic non-interesting terrain, and on to other stuff.


Been looking at http://www.infinity-universe.com/Infinity/index.php. Sounds promising as well.

Or optionally have the time rate vary with the distance to the nearest actual fighter?
Taking out a weapon would count you as a fighter, but it would be impossible to walk up at normal speed, take out a knife, only then slowing down, and backstab them without much time to react.

I like that idea.
You would slow as you approached, until you matched their speed.
Bullets shot into their area would slow too.

Boring Coding is Boring. Loading textures, storing values, checking pointers, administrating, debugging blahblahblah.

Really, with a job and a kid and a gf and a gaming addiction, if this thing is done by 2030 it'd be FAST.

I intend for my game to never be finished.

The only thing close to finished would be if I started a similar concept from scratch,
 in order to rectify flaws of the underlying structure,
 leaving an incomplete "game" behind.

I like my little universe, and programming the hell out of it on occasion is fun.

But what happens when you inevitably add something incompatible about 4 years back...

Which your engine depends on fundamentally?

From experience: Then you start redesigning your engine, give up halfway through, and put it in the folder with "Unfinished Projects".  ;D

Currently rewriting the whole static terrain-grid-structure. The World is just a small container, containing an x number of currently-visible top-level terrain, loaded from the database. When the player moves, new terrain is added, and either loaded from the database or newly created and added to the database for future reference. The database API is written such that it does not matter whether it's from a database or coming from a server.

The terrain is all linked together through vectors of "neighbour" pointers, so the terrain ID needs to be deductible from its relative position in the world. It's possible to determine it like (1000 * y) + x, but that implies a maximum nr of x of 1000, which is not infinite, by far. So x and y relative to terrain 0 needs to be stored, giving a max x of int64 and a max y of int64. As each of those top-terrains contains a fairly large piece of land, that should be enough.

.. or is it?

Calculation:
int64 has a range of -9,223,372,036,854,775,808 through positive 9223372036854775807. One piece of terrain is 343 x 343 X 343 m, although I intend to make them larger to allow for mountains higher than 343 m (2401 m should be high enough), or allow vertical stacking of terrain where necessary.

This means the world can be 3163616608641188101 km wide, 3163616608641188101801 km long, and 3163616608641188101801 km high, or 21147452563 AU. This is enough to cover the entire GALAXY in terrain. Really. It might (MIGHT?) be overkill, but when I say infinite, I want to be ready. ;)

Right, that's done. Now to render it. Which is lists of vertices within lists ordered by type and per object for removal and and I need some thinking.
