...thread. The discussion, while it may have occurred before, is now seen for the first time by me.
It appears that the issue here is:
Creating a planet that looks like a sphere from space or high enough off the ground, looks flat from ground level, has equal gravity over the entire surface (that supports the illusion of flat ground, like a real planet), projects a spherical gravity well into space, and is made of cube-shaped blocks which can be removed down to and including the planet\'s core..
This is impossible.
Everything is possible in that sentence, until you hit the \"made of cube-shaped blocks\" part.
Once you add that, the whole thing falls apart.
Cube shaped blocks require that either the planet does NOT appear flat in some areas (where it requires you walk over the corners of cubes)...
OR it requires that you not be able to drill to the planet core - because at some point you WILL run into the issue of a sphere requiring block shapes that are NOT cubes.
--------------------------------
THEREFOR
I suggest that planets be made so that you CANNOT drill down beyond a certain point (a point at which drilling further would force encounters with non cube-shaped blocks) - at that point, you must use weapons to destroy the planet core, which will explode and create a shockwave that will damage any insufficiently-shielded ship - but afterwards you can collect whatever remains (and if you do not, possibly it will turn into asteroids).
The problems I foresee:
This will take alot of coding, and thus, time.
This will require that planets become MUCH larger (I\'m talking they take up a goodly portion of a sector or something), in order to allow for a large enough surface that it will seem flat (and allow for bending the flat surface around the sphere). More coding. IF it is even possible without demanding instanced planets, due to potential server issues caused by such technique (I think someone mentioned before)...more coding.
This will in turn require a rework of the sector system, I think. MORE coding
You see the trend here.
More.
Coding.
Which, if you are not aware, equals time. Time spent on building a specific and non-space system (planets) in a game which is FOCUSED on space, and spaceships.
Planets large enough to allow for flat-seeming ground while actually on a spherical surface would change a vast number of things about the game - players could in theory spend vast amounts of time on a planet, creating mining vehicles or something, and selling the ores to space-born-players.
Or something...
So basically, I don\'t think creation of spherical planets should be a serious focus of the design team at the present time.
IMO.
