@JonasByström -- then yes, indicators on the display. Though the indicators are far far larger than the actual ships, objects in the battle space are sparse enough that there is seldom any real overlap (and if there is, and it's meaningful to the player, it's almost certainly going to be happening nearby). Honestly, I'm still working it out, though.

@Constantius - downloading now. Looks awesome. :-)

@MSalters - right now, Newtonian. For the most part, objects don't get going relativistic speeds -- even two missiles burning right at each other at full speed from opposite sides of the battle space end up with closing speeds of about 20% the speed of light. Enough that one could model relativistic physics and get slightly different results, but it won't be that huge of a difference. I want to explore modeling relativistic physics, though -- I think it could make for some seriously interesting gameplay.

comment Modeling speed of light information propagation in space combat sim
@JonasByström - the long-distance view is pretty complex, and I'm trying to clean it up. Basically, I'm hoping it to be a probabilistic view of where the target will be in the future, based on light lag and your ship computer's estimates of the target's max delta-v. Right now it's rather less awesome than that, though :)

I already sort of model the changing position and speeds. Despite the scale, objects in the game don't generally get going an appreciable fraction of the speed of light, so events overtake them relatively easily, but there is a check at each tick if the receiver is in the the sphere that could have seen the event, so if you're moving toward or away at a good clip it can affect this by a few ticks. Doppler would be interesting indeed, though! Something to look into. :-)
