minetest-mm/mods/moretrees/screenshot.lua

-- Usage:
-- - Create a new world
-- - Set world mapgen: v6
-- - Set world seed: 2625051331357512570
-- - Enable the moretrees mod
-- - Edit the moretrees source
--   - Disable all trees in default_settings.lua
--   - Recommended: make saplings grow fast in default_settings.lua:
--     sapling_interval = 5
--     sapling_chance = 1
--   - Apply the patch below to moretrees
--     (so that jungle trees are always large, and differently-colored):
--     use 'git apply --ignore-space-change'
--   - Make sure this file (you are reading) will be loaded when minetest starts !
--     (e.g. add 'dofile(modpath.."/screenshot.lua")' to init.lua)
-- - Start minetest
-- - Goto 700,y,-280 (approximately)
-- - Make sure the world is loaded between x = 650 .. 780 and z = -350 .. -180
-- - Give the chat command '/make-scene'
-- - Wait & walk/fly around until all trees have grown
-- - goto the platform at 780, 30, -277
-- - Set the viewing range to 300, with fog enabled
-- - Take a screenshot.

-- Patch to apply to moretrees

The following is a search/replace command suitable for vi (/vim) or sed, to convert minetest log
messages to equivalent lua commands:

s/.*\(\(moretrees\|default\)[^ ]*\) at
	(\([-0-9]\+\),\([-0-9]\+\),\([-0-9]\+\)).*/\t\tminetest.place_node({x=\3, y=\4, z=\5}, {name="\1"})/

E.g. a minetest log line of the following kind:
		2016-07-03 11:30:50: ACTION[Server]: singleplayer places node moretrees:rubber_tree_sapling at  (760,5,-223)
Becomes:
		minetest.place_node({x=760, y=5, z=-223}, {name="moretrees:rubber_tree_sapling"})
(Except that the example log line above has an extra space added, so it won't be converted)

vi/vim users: Add the minetest log lines to this file, then enter the following command, with
<expression> replaced with the search/replace expression above.
	:%<expression>

sed users: Add the minetest log lines to this file, then execute the following command at the shell
prompt with <expression> replaced by the search/replace expression above. Don't forget the
single-quotes.
	sed '<expression>' < screenshot.lua > screenshot-new.lua

Windows users: You're probably out of luck. And the effort of doing such a thing is probably
larger anyway than the effort of copying an existing line and typing things manually.
