All right, I'm not quite sure this is the right subforum to post in, as it's more about how to design things from a technical standpoint, rather than how the game should be designed in the first place. So, I just got done making a game for work, and the next project is about to start. It will be a multiplayer space shooter where people fight aliens. So far, so good - now the thing I really don't know how to design is the battlefield itself. The fight takes place on a small planet. Now, if this planet somehow had its boundaries, like the Lunar Colony battle map from Mario Kart 8 for instance, it'd be quite easy to design - just design a regular map and use a shader to make everything look cool and bend on the horizon. But the thing is that the players can freely move and wrap around the planet. Thus, I don't think designing a flat world and making it bend with a shader is gonna work. My question is, what would be the best way to design worlds like this? I'd like it to be tile-based but I doubt squares map nicely to a sphere, so I guess pentagons and hexagons are the way to go? How would I go about placing large objects on the map that would neat to be deformed in order to adjust to the planet's terrain (like halls covering large chunks of the planet, etc.)? Without doing the bending via shaders, I guess it'd need to be modelled in the model itself, but that way I'm also limiting myself in case I ever change the planet's radius and the bending becomes more/less severe. It sounds like a tricky thing to design, so any suggestions and ideas are welcome.
