In all other topics i have seen that involve this type of mechanic it is disregarded as being too "hard to program" When it would actually be a simple exercise in programming Altering what they've already done. They already have a mechanic for looping worlds horizontally so in my surprisinglyinferior knowledge of programming it would be somewhat like this (LOOP 1 TO LOOP 2 VISE-VERSA) *Current build L1SURFACESURFACESURFACESURFACESURFL2 *Le alternate build L1SURFACESURFACESURFACESURFACESURL2 l1 l1 l1 l1 l1 l1 l1 l1 l1 l2 l2 l2 l2 l2 l2 l2 l2 l2 I may be completely mentally unstable, but the reasoning is sound. (Argument one) Your a stupid face because Gravity. (Rebuttal one) Any gravity problems could be solved with a bit of reasoning, I.E if you dig a hole all the way through the earth either you will have some kind of heat proof ship and considering that there would be very little gravity-based physics (Up, Down, ect) that far down, cameraplay could be oriented around the player (think spore cell stage) or if you stayed platformer style, staying down there without a ship would not last long enough (Ending in either death by pressure/heat, or hellevator style speedy falling [I.E. Speedy thing goes in, speedy thing comes out!]) Any other arguments? *Edit to make better people understand my words, for great justice!
It's true that it would be cool to dig from one place of a planet to the opposite side by passing through the center, but how will they do for the center? I think, there will be a problem because the circumference at the edge of a planet is larger then at the core. So will they shrink gradually the blocks to fit in the center or will they put lesser and lesser block nearer you get from the center? I think your idea is a good one and I wish they put it in the game.
My argument: Even if it was it wasn't that hard to program this mechanic your suggesting, it would still be time consuming to add it in. and if you consider that players would most likely only dig to the centre of a planet just the once (for curiosity reasons; i.e. to see what happens when you dig to the bottom), then it just wouldn't be worth it to waste time on a mechanic that wouldn't affect core gameplay. But if what you say is true about this topic being beat down in other suggestions, then you have my respect for posting your idea anyway. EDIT: This post now comes with 30% less spelling errors!
I wouldn't mind this being implemented just for the cool factor. But if there's no other reason game play wise TO do it, like having super dense metals/crystals or other rare/dangerous materials to mine, then i doubt it will be in. I suppose a way to implement it might be when you pass the halfway point of the core, the camera flips upside down along with gravity, but in a 2D environment, it might not look right. The core would end up stretched as far as the surface length wise. i suppose it could work though.
You'd either have to have some transition location for moving between layers or both layers would have to be actually one map with screen going upside-down (as I see now, was already mentioned by R_C_A^) at some point. But then, you also have the surfaces connected to each other so walking around is possible. At this point, if you really want to have digging-through system you'll have to ignore fluff, remnants of realism etc. Going through the molten outer core of the planet will require more than just heat-resistant hull. Also, making a hole thorough the whole planet is bound to mess things up. Lastly, you seem to underestimate gravity. At the very core of the Earth there probably would not be any gravity but before then you'd probably be crushed. Currently exploration of oceanic crust is hard as you need reinforced equipment to go so far down. And there's a far longer way down before the pull of gravitational field will start to feel weaker.
Planets must not have side or top boarders and at the bottom they should have something that stops you going any further but never, ever, an invisible wall
If we assume that the planet in question is like Earth. The outer core of the planet is molten, with the inner being still solid, at least according to the general info and presumptions about our planet.
for the flipping of the camera it wouldn't be an issue Because you would either be in a camera-amorphis ship, dead, or going through it so fast that it wouldn't be noticeable But for the warping i guess the core would have to be sized proportionately
