I think it's good that there is the possibility to rotate buildings before you build them. But is there also the possibility to align them straight? An auto align function?
If a planet spins it will have a east (and thus the other directions). Or meaning having preferred direction in which it would be easier to place buildings?
East is the direction in which the planet spins. West is the opposite of that. North is in your left when you look east and south to your right. They are directions, not positions. That north and south pole and can be dually thought of as positions doesn't make thinking of east or west any more diffcult. In a similar way down poles but up doesn't and up is no less real a direction than down.
You are absolutely correct, but my post was in response to DeadStretch's post (despite me actually quoting your post).
Buildings could align to nearby buildings. This means that no direction is preferred for the first building you place but after that nearby structures could be squared up. Of course this only work locally, any alignment system only works locally.
at what distance do you define locally? when to seperate 'local' systems become close to each other, which is the one that is used? this is plausible but i think it would be far far easier to just partially build off the grids that are already being generated for pathfinding.
