Pre-generating part of a map

by nif » Post

hi
how can i pre-generate part of a map (say rect 4096x4096 with zero in the center or some radius over the center)
without boring flying over the whole part manually?
especially if has used heavy mods for biomes, this ability is very needed.

create a mod with this line:

Code: Select all

minetest.emerge_area ({x=2048,y=0,z=2048},{x=-2048,y=128,z=-2048})
adjust the y values to suit your purpose

Or use the chat command " /emergeblocks (-2048, 0, -2048) (2048, 128, 2048) ". Beware, this might take a while, so I recommend generating smaller map parts first to check whether it works as desired.
Look, I programmed a bug for you. >> Mod Search Engine << - Mods by Krock - DuckDuckGo mod search bang: !mtmod <keyword here>

not sure if they still work but there are mods that let a bot fly around in a defined pattern such as:

explore_map by echo and
os_explore by oleastre

also you might get hold of the code that powered the luigi-bots and derivats somewhere but beware that might be dangerous terrain out there and you might get banned on sight - so please don't use such devices on other people servers.

Those mods probably shouldn't be used - they're inefficient. They were written before emergearea was added

its awesome!
both solutions is what i need

Code: Select all

/emergeblocks (-512,0,-512) (512,64,512)
its a great command, even with realtime statistics of generating process

and

Code: Select all

minetest.register_chatcommand("gen1", {
	params = "",
	description = "",
	func = function()
		minetest.emerge_area ({x=512,y=0,z=512},{x=-512,y=64,z=-512})
	end,
})
is nice for automatisation, but what happens may be seen only over cpu loading and change size of map.sqlite file

this issue was a big pain in the ass :)
thanks a lot guys!

hmmm, in a fresh v7 map I could emergeblocks for 5km in each direction at floatlands altitude, then create a Carpathian game and replace its sqlite map file with the one containing floatlands -> a Carpathian land with floatlands!

When I use this command and specify a non-trivial area I get assertion failures and crashes. For instance, when I ran this:

Code: Select all

/emergeblocks (-2048, 0, -1500) (2048, 128, -1000)
minetest quit shortly after with this message:

Code: Select all

minetest: /build/minetest-oSA5qg/minetest-0.4.17.1/src/emerge.cpp:391: bool EmergeManager::popBlockEmergeData(v3s16, BlockEmergeData*): Assertion `count_peer != 0' failed.
If I shrink the z difference down to 300 it works.

Have you reported it in https://github.com/minetest/minetest ?
