11:05 rmilan        it is possible to delete map blocks with mods? to reduce map size [and regenerate]
11:05 PilzAdam      no
11:07 rmilan        then there should be commands like /build and /mining, to change player's mapfile to modify
11:07 rmilan        i mean, if i do a /build, its saved to map_build.sqlite, if mining, then map_mining.sqlite :D
11:07 rmilan        and can delete mining, when the map is big and bad, and keep the built things [and generate maybe new map with chaning seed]
11:08 rmilan        but it would be buggy without flatmap
11:08 PilzAdam      rmilan, its on the TODO list of the core devs to only save blocks if they are modified
11:09 rmilan        i know, but that would save mines also
11:09 rmilan        and i often want to delete mines because its make big holes if more player mining
11:09 rmilan        but its player specific :D
11:09 PilzAdam      you could use rollback for that, I guess
11:09 rmilan        so i could delete those nodes with script
11:10 rmilan        if that will be done
11:10 rmilan        anyway its hard to make save only diffs?
11:10 rmilan        i mean, its not only about save the modified nodes only, others will be generated all the time?
11:10 rmilan        and maybe keep in memory
11:10 rmilan        some change in code, or big?
11:11 rmilan        anyway sorry for asking here, but i wont bother dev channel :D
11:11 rmilan        i dont even know c++, just asking :D
15:50 ShadowNinja   rmilan: Saving only modified nodes would be difficult, and it might end up taking up more space as it is pretty much a rollback log in reverse and those are known to get bigger than the map. Saving only modified blocks(chunks) would be easier to implement and should reduce the map size quite a bit.
15:50 PilzAdam      ShadowNinja, not nodes, blocks
15:54 ShadowNinja   PilzAdam: Hmmm?
15:54 rmilan        a bit? i think still much diff would be, if someone walk around when bored, its not saved
15:54 ShadowNinja   The TODO mentions both saving only nodes and saving only modified blocks.
15:55 PilzAdam      ShadowNinja, http://dev.minetest.net/Terminology
15:55 ShadowNinja   rmilan: I meant a lot.
15:55 PilzAdam      there are no plans to save single nodes
15:55 * ShadowNinja knows the terminology.
15:55 rmilan        i saw somewhere nodes also :D
15:56 ShadowNinja   Instead of storing everything in the database, only store the changed mapblocks (or even only modified nodes?). This would save a lot of space. -- dev.minetest.net/TODO
15:56 rmilan        only store the changed mapblocks (or even only modified nodes?)
15:57 rmilan        from: http://dev.minetest.net/TODO#Store_block_differences_only
15:57 rmilan        hm, i was slow :DD
