From: paramat Date: Wed, 21 Jun 2017 03:20:18 +0000 (+0100) Subject: CavesRandomWalk: Make 'lava_depth' a mapgen parameter X-Git-Tag: 5.0.0~1071 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=2652d8db19fb2758de1da4c04ce169f80c87e5c7;p=oweals%2Fminetest.git CavesRandomWalk: Make 'lava_depth' a mapgen parameter As with 'large_cave_depth', lava depth was previously a fixed y value and therefore incompatible with the ability to shift terrain vertically. Add 'lava_depth' mapgen parameter to mgflat, mgfractal, mgv5, mgv7. --- diff --git a/builtin/settingtypes.txt b/builtin/settingtypes.txt index ebdc9f752..f15fc679b 100644 --- a/builtin/settingtypes.txt +++ b/builtin/settingtypes.txt @@ -1028,9 +1028,12 @@ mgv5_spflags (Mapgen v5 specific flags) flags caverns caverns,nocaverns # Controls width of tunnels, a smaller value creates wider tunnels. mgv5_cave_width (Cave width) float 0.125 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. mgv5_large_cave_depth (Large cave depth) int -256 +# Y of upper limit of lava in large caves. +mgv5_lava_depth (Lava depth) int -256 + # Y-level of cavern upper limit. mgv5_cavern_limit (Cavern limit) int -256 @@ -1137,9 +1140,12 @@ mgv7_spflags (Mapgen v7 specific flags) flags mountains,ridges,nofloatlands,cave # Controls width of tunnels, a smaller value creates wider tunnels. mgv7_cave_width (Cave width) float 0.09 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. mgv7_large_cave_depth (Large cave depth) int -33 +# Y of upper limit of lava in large caves. +mgv7_lava_depth (Lava depth) int -256 + # Controls the density of floatland mountain terrain. # Is an offset added to the 'np_mountain' noise value. mgv7_float_mount_density (Floatland mountain density) float 0.6 @@ -1218,9 +1224,12 @@ mgflat_spflags (Mapgen flat specific flags) flags nolakes,nohills lakes,hills,no # Y of flat ground. mgflat_ground_level (Ground level) int 8 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. mgflat_large_cave_depth (Large cave depth) int -33 +# Y of upper limit of lava in large caves. +mgflat_lava_depth (Lava depth) int -256 + # Controls width of tunnels, a smaller value creates wider tunnels. mgflat_cave_width (Cave width) float 0.09 @@ -1257,9 +1266,12 @@ mgflat_np_cave2 (Cave2 noise) noise_params 0, 12, (67, 67, 67), 10325, 3, 0.5, 2 # Controls width of tunnels, a smaller value creates wider tunnels. mgfractal_cave_width (Cave width) float 0.09 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. mgfractal_large_cave_depth (Large cave depth) int -33 +# Y of upper limit of lava in large caves. +mgfractal_lava_depth (Lava depth) int -256 + # Choice of 18 fractals from 9 formulas. # 1 = 4D "Roundy" mandelbrot set. # 2 = 4D "Roundy" julia set. diff --git a/minetest.conf.example b/minetest.conf.example index 9a71ec562..d0ed146e0 100644 --- a/minetest.conf.example +++ b/minetest.conf.example @@ -1256,10 +1256,14 @@ # type: float # mgv5_cave_width = 0.125 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. # type: int # mgv5_large_cave_depth = -256 +# Y of upper limit of lava in large caves. +# type: int +# mgv5_lava_depth = -256 + # Y-level of cavern upper limit. # type: int # mgv5_cavern_limit = -256 @@ -1375,10 +1379,14 @@ # type: float # mgv7_cave_width = 0.09 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. # type: int # mgv7_large_cave_depth = -33 +# Y of upper limit of lava in large caves. +# type: int +# mgv7_lava_depth = -256 + # Controls the density of floatland mountain terrain. # Is an offset added to the 'np_mountain' noise value. # type: float @@ -1480,10 +1488,14 @@ # type: int # mgflat_ground_level = 8 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. # type: int # mgflat_large_cave_depth = -33 +# Y of upper limit of lava in large caves. +# type: int +# mgflat_lava_depth = -256 + # Controls width of tunnels, a smaller value creates wider tunnels. # type: float # mgflat_cave_width = 0.09 @@ -1530,10 +1542,14 @@ # type: float # mgfractal_cave_width = 0.09 -# Y of upper limit of large pseudorandom caves. +# Y of upper limit of large caves. # type: int # mgfractal_large_cave_depth = -33 +# Y of upper limit of lava in large caves. +# type: int +# mgfractal_lava_depth = -256 + # Choice of 18 fractals from 9 formulas. # 1 = 4D "Roundy" mandelbrot set. # 2 = 4D "Roundy" julia set. diff --git a/src/cavegen.cpp b/src/cavegen.cpp index dbed79951..a2ecca483 100644 --- a/src/cavegen.cpp +++ b/src/cavegen.cpp @@ -258,7 +258,8 @@ CavesRandomWalk::CavesRandomWalk( s32 seed, int water_level, content_t water_source, - content_t lava_source) + content_t lava_source, + int lava_depth) { assert(ndef);
