World Origin Rebasing (multiplayer)

The worst case without rebasing would be a map, so big, that there are nore more digits available after the comma. That would be like replicating an integer for the position. You couldn’t move between two integers, very rough movement. So yes, rebasing allows you create bigger areas, because you snapping the origin to another grid cell after X units.

I’m not sure, but theoretically, nothing limits the mapsize, if you rebase in combination with level streaming properly. I don’t know how well the normal character component replication would handle such speeds, but if you plan to make a custom actor for the fighter, at this high speeds, you need proper extrapolation if you want responsive controls.

If I understand the issue correctly then running out of decimals is precisely what sets the 20km or (+/- 10km from origin) limit. With 32bits, you’re limited to 7 digits and the standard unit is 1cm, which gets you to 1,000,000cm or 10km if you are allowed 7 digits (is it actually 999,999.9cm, because you have to have one decimal?).

The game is already working pretty well (from a very rudimentary point of view) with the higher than normal speeds. Granted we have yet to make a dedicated server build and deploy it on a proper server with a fiber connection, so we are hoping that some of the “less than good” stuff we’re experiencing is due to running on listen server desktops with normal home connections.
