My progress so far
After sitting in front of the computer for hours today, I finally managed to make some progress.
Now it really behaves like a civilization: it consumes resources, has its stability (which decreases if developing too fast), and can only see the objects inside the light cone (the big dark blue circle on the scene).
A big change is that now the development pace of the civilization can be set (while shown by the circles at the bottom) and the development points & levels are counted. What’s more the Energy Dev. Point now has effect – less resources are used by civilizations with a high Energy Dev. Point. Plan to add another feature: more resources are got when the Energy Dev. Level goes up.
Hope I can successfully launch spacecrafts and meet aliens soon
Good luck to everyone, especially those in the IRC room who still have problems
