Hey, this is a topic that everyone seems to approach as a no-brainer, yet I've for some reason failed to understand. Keep in mind I've had this question for months and am only just now finding the urge to actually reach out for help.
Basically, I don't fully understand the RPG 3/4 perspective. In Cyangmou's DeviantArt tutorial on "cubes", as well as many other guides, I see a block drawn as follows:
Each face of the cube is 16 x 12. But what would the actual floor tile sizes be? In most guides, they seem to actually refer to the 16 x 24 block as a 16 x 16 one.
Here is a mock up of how the cube looks on top of 16 x 16 tiles:
But there are clear issues, for example, assuming both resolutions were snapping to the same grid, any two horizontal rows of the red blocks couldn't really touch each other due to the 4 pixel gap between 12 and 16.
So logically I thought, why wouldn't the floor tiles be 16 x 12 themselves? Seems reasonable, aside from the fact that I've literally never heard of any game using rectangle tiles.
Someone please explain why i'm so incompetent.
