Increase maximum number of terrain types

[Chuck Wilder]

Current code supports a maximum of 16 terrain types per world. Refer to http://wl.widelands.org/forum/post/233/ and more recently http://wl.widelands.org/forum/post/5557/
A larger number is desirable to increase the graphic variety that could be achieved in the maps given the availability of more terrain types such as multiple water graphics to differentiate between inland lake, river and ocean water or other new and possibly animated terrain.

A question: Would increasing the number of terrain types have an impact on the use of S2 maps as long as the order of the first 16 types was maintained? And is even that necessary?

I am currently unable to answer the question :(. Need to look at the code.

Marking this confirmed, since multiple people would like to see this. (Lastly http://wl.widelands.org/forum/topic/1105/?page=1#post-8647)

Seems like a good idea to just merge the worlds into one big one and be a little more clever about what gets loaded and when.

See also wish / bug #951554 (Impassable water), which depends on having more terrain types.

I advise to take Attributes for "artifistic Impassable" (and any other Attributes) but I won't call it impassable Water but DeepWater resp unwadable as if you can swim I don't see a Reason to wall Swimmers (eg Ducks ;).
Attributes for Passing_Matters throw Logic on a Problem which is arithmetic (geometric). Both Ant and Ship can't pass if they can't deal with a Deep of WaterTerrain while a Horse can wade through. We can beat the Problem dead with Logic (Pass-Flags) but we deal here with an geometric Matter and should prefer Aritmethic. For GameMatters like Campaign ("you still can't walk this way..", blocking Fog, etc) we may prefer the Flags but for physical Matters (in particular Geometry - Metry of Geo) we may prefer Numbers. Bread or Butter, what we will take?

Got me all exited with that bit of news, SirVer :)
It will not be an "unlimited" number of different terrains, I suppose.
How many, if you really want to merge all "words"?

[SirVer (sirver)]

There is no arbitrarty limit on the number of terrains that can be defined in a world in the branch. Also, as long as you do not rename a terrains name, all old and new maps should stay compatible. Right now there are ~60 terrains defined (64 from all worlds, but there were some duplicates like lava and some water terrains), but nothing stops you from defining another 60. :)

Based on the previous comment, now that one_world has been merged, this has been fixed?

Fixed in build19-rc1.
