I think the galaxy map - positions of planets should really be something in this mod. 1. A 3D galaxy map. This is required. For the ideas like eclipses, of course. 2. Eclipses. You can see the positions of planets in the sky, (using a telescope) and sometimes, the moon may cover up the sun. This causes one part of the planet to be cast into shadow. Staring straight at the sun like this gives you bad, bad blindness, if you don't look away quickly. 3. Needing to use things to see the galaxy map. This might be a tracking station or something. Possibly you use a telescope, or some kind of satellite... in creative mode, nothing! 4. Finite planets. (Large, of course) ESSENTIAL. Each planet/moon is of a different side size. The planets would (obviously) be cubes, with... possibly soft edges and corners, maybe diagonal wedges of blocks at each edge. Sharp edges would not be very nice when you walked over them, you would feel like you were falling over a cliff. Each corner and wedge... would be big-ish, enough for something like a house on the corner of the world. There would be poles, an equator etc. If you are wondering about this problem: some people may have their world further than the planet boundaries - no, they cannot, because there is a limit to minecraft worlds currently, its just not a super-cool cube. I think that the current way worlds are generated on the large scale is NOT good. It isn't the lovely, neat large islands surrounded by water that it should be. At least that's what I thought I saw! Of course, flying off a planet shows the cube below, as you come off that certain part on the map(s)! It would update periodically, e.g. if ever giant Inter Planetary Ballistic Missiles were added, you would fly off the planet, fleeing, while you see this huge missile come and blow the planet to bits. In the GUI it would say: 'Planet debris' or something. Of course, I am not suggesting these IPBMs, leave that to ICBM. Bedrock would be dig-able, (just about) and going below the (thicker) layer of bedrock would see you fall into the MANTLE! Loads of lava, but of course, having all that as blocks is a waste of coding and stuff, (unless you want to have a base in the mantle ) so going there, even in creative mode would be DEATH. 5. Flying duration It would have to take time, the further your destination was from you. And consume more fuel. 6. Longer orbit times. Firstly, as you may all agree, the time a celestial body takes to orbit would be correct, in the minecraft time scale. E.g. you have to wait 365.24 minecraft days to have a year. Same stuff for other planets. Obviously, you would not be able to sleep on another planet if not everyone is in bed on other planets. 7 - off topic Beds on other planets (and other dimensions, for that matter) MUST not explode! 8. Change the minecraft time scale in config I'd love to be able to make days 24hr, or some people may want to have 1 hr and all that. 9. Telescopes and astronomy Uses the entire point of this thread, the planet positions stuff. All that is done is to see the planet icons zoomed in, except obviously use the finite planets' terrain image instead of the icons. THIS is where you discuss telescopes and astronomy, not rudely resurrect a deleted thread.
