Some people, I tells ya...
This one has been suggested to death, but it\'s still a really good idea. From a practical perspective, it would work far better as a simple teleportation from point A to point B, rather than having the ships actually accelerate to the kind of speeds we\'re talking about (as the game would have to go into overdrive loading everything you pass). And since there\'s already code for fixing block collisions, it shouldn\'t be too hard to do something about the issue of winding up inside of something.
The question that really needs to be asked of these topics is, how would we like fast travel implemented? We could have:
Naturally occuring wormholes:
Essentially these spit you out at another wormhole somewhere. These would make exploration worthwhile, and would be a good point for factions to defend.
Wormhole Gates:
Essentially an artificial structure that sends you to another wormhole opening. This is not mutually exclusive with naturally occuring wormholes. Upon firing it up, a menu could come up showing wormholes within range, and the user could pick one. The range could be determined by the available power; the farther the destination is, the more power is consumed. Note that this could either be a physical gate or some sort of cannon that creates a wormhole in space.
Hyperspace/Slipstream Jumps:
An actual warp drive that just makes you go really fast is a bit out of the question (as stated earier), but something close can be accomplished. Essentially the ship jumps to another dimension (somewhat like the Nether in MC) where the coordinates are scaled, so traveling 1 km in hyperspace nets you, say, 8 or 16 in normal space. This dimension would contain nothing but ships that went to hyperspace, and building would be disabled. Staying in hyperspace should probably consume power. Bonus points for cool effects in the background.
Tesseracts:
Probably the route that requires the least work on Schema\'s part. Essentially the ship moves by folding space around it; this would act like just a straight up teleport. Again, range would be based on available power, and perhaps a menu could be opened to \"tune\" the amount of power put into it when activated. A cool little particle effect would be nice.
