Apologizes for self-bumping this thread, but I'd like to post an update. Worked on stone tiles a bit, which is also the reason for this comment. I'll update the initial post also to include some details.
Rock, stone and mineral patternsThe stone and rock tiles are moving away from abstract idiographic symbols and towards representative tiles in comparison to some of the other tiles in the set. So I tried to setup a system of classifying stones for stonetiles, and looked up some images from google to try and decide which category each stone type should go into. The actual categorization (which isn't implemented in this version properly), is something along these lines:
SMOOTH ------- COARSE
How grainy is the texture?
PLAIN ------- MOTTLED
If there are spots in the texture?
PLAIN ------- STRIPED
If the rock appears to be composed of strata or layers?
AMORPHOUS ----- CRYSTALLINE
If the rock has crystalline or rounded structure?
These would then allow the creation of multiple rock wall tiles, depending on which features are present.
STRIPED and MOTTLED can be treated as mutually exclusive, kind of like a triangle instead of an axis, to reduce the number of required tiles.
Plants and vegetationSome classification of similarity regarding plant tiles. Such as if the grass appears long, or short, if it's flowery or not. Somewhat simpler classification in comparison, could be developed further?
Continued working on the 18x18 format and haven't worked on the 20x24 format any further recently. The larger size kind of makes the environment very much zoomed in, so I've started to prefer the 18x18 version.
The rock update requires yet another version of raws, which I've not provided yet. There's also some additional changes, such as bunnies having their own tile ('v'). Here's an image of the current version:
Here's also a reference image for how some of the rocks look like. The tile with the symbol is for minerals such as native silver, platinum etc.
Unfortunately this reference image doesn't show many types of tiles.
What do you think? Does the stone classification make sense? Perhaps (you) could try doing something similar with (your) tileset?
PS. If anyone wants to use any tile of this tileset, or a derived tile based on some of these tiles, in their own graphics or tileset, feel free to do so. It would be flattering if that happened.
