Details:
freim (Hogne) on IRC was asking why our tilesets have both "river-as-special"
and "river-as-terrain" definitions, and whether new tilesets need both.
For instance, Amplio2 has the following river-related stuff:
data/amplio2/terrain1.spec:
2, 0, "t.l0.grassland1"
2, 0, "t.l0.t_river1"
...
11, 4, "ts.grassland_resources", "ts.river_resources"
data/amplio2/water.spec:
; Rivers (as special type), and whether north, south, east, west
; also has river or is ocean:
2, 0, "tx.s_river_n0e0s0w0"
2, 1, "tx.s_river_n0e0s0w1"
2, 2, "tx.s_river_n0e0s1w0"
2, 3, "tx.s_river_n0e0s1w1"
2, 4, "tx.s_river_n0e1s0w0"
2, 5, "tx.s_river_n0e1s0w1"
2, 6, "tx.s_river_n0e1s1w0"
2, 7, "tx.s_river_n0e1s1w1"
3, 0, "tx.s_river_n1e0s0w0"
3, 1, "tx.s_river_n1e0s0w1"
3, 2, "tx.s_river_n1e0s1w0"
3, 3, "tx.s_river_n1e0s1w1"
3, 4, "tx.s_river_n1e1s0w0"
3, 5, "tx.s_river_n1e1s0w1"
3, 6, "tx.s_river_n1e1s1w0"
3, 7, "tx.s_river_n1e1s1w1"
; Rivers as overlay
2, 0, "t.t_river_n0e0s0w0"
2, 1, "t.t_river_n0e0s0w1"
2, 2, "t.t_river_n0e0s1w0"
2, 3, "t.t_river_n0e0s1w1"
2, 4, "t.t_river_n0e1s0w0"
2, 5, "t.t_river_n0e1s0w1"
2, 6, "t.t_river_n0e1s1w0"
2, 7, "t.t_river_n0e1s1w1"
3, 0, "t.t_river_n1e0s0w0"
3, 1, "t.t_river_n1e0s0w1"
3, 2, "t.t_river_n1e0s1w0"
3, 3, "t.t_river_n1e0s1w1"
3, 4, "t.t_river_n1e1s0w0"
3, 5, "t.t_river_n1e1s0w1"
3, 6, "t.t_river_n1e1s1w0"
3, 7, "t.t_river_n1e1s1w1"
;river outlets
4, 0, "tx.river_outlet_n"
4, 1, "tx.river_outlet_e"
4, 2, "tx.river_outlet_s"
4, 3, "tx.river_outlet_w"
I find the tileset code hard to follow, but with our default ruleset, as far
as I can tell, only s_river_* and tx_river_outlet_* are read (experimentally
this is the case). I can't see code that would read any of the rest, absent a
terrain type called "river".
Does anyone remember why the others are there? Are they some ancient backward
compatibility thing that can now go? Or is there some modpack out there that
treats river as a terrain type, or something? Can anyone remember the
history?
Given the lack of documentation, it would make tileset authors' life easier if
extraneous fluff could be omitted from the examples we provide.
