Block data is already compressed when sent over the network. See MapBlock::serialize() in mapblock.cpp.

@Evrim Of course, the server could check if a player moves too fast (and actually the server could control all player movement, while currently it's all client-side), the server could check if a player placed or removes blocks too fast, and so on. It just isn't done currently.

@Staffs: It could be useful for survival maps. Let's say they start you out with an initial inventory and you have to complete the goal without picking anything up, this setting could be used to enforce that.

My guess is that making auth.txt read only will not prevent new players from logging in, because auth.txt isn't re-read as long as the server is running. Once (and if) my patch setpassword is included, you can set default_password in minetest.conf and new users will only be able to log in if they kn...

You place them somewhere (preferably on dirt but afaik any material works at the moment), then they instantly grow into a tree after some random time. You may have to stay near them to make sure the blocks stay loaded and active. The light level at the sapling doesn't matter.

FYI, if the problem primarily happens when you login to a server (or to a local game), it seems to be a bug with the way gravity and collision detection works. When the client environment doesn't update for about half a second (that's often the case when you login), depending on the floating point i...

Good idea! Another idea about the crafting description. The way you proposed ties the crafting recipes to the 3x3 crafting square. In case this would be extended or reduced (e.g. if a workbench is ever added) something more generic would be better. Maybe: in 1: apple in right of 1: steel_ingot in le...

What were the most important items that you lost from your inventory? If you post your (new) sam player file, I will add them back.

Try to delete the "map/players/sam" file and see if the problem goes away. That file seems to be damaged (and the inventory is already lost anyway). I have no idea know how such a thing could happen.

I tested, now converted map is correct. Thanks. About coordinates. I think that up and down in minetest world is Z axis. But, seems, I thought wrong? Minetest uses the same coordinate system as in Minecraft (except that elevation is not limited to 0 to 127). So Y is up/down. (It's true that many FP...

I just rebooted my computer twice to no avail. I have a decent graphics card and 2 GB of RAM. When I first start minetest, I'm at about 30 FPS, but in about 15 to 20 seconds, its down to 10 or less.I was just at 3. Then I disconnect and start again and the process repeats.

Black trees are already in the game ;)

But if they were to become an intended part of the game, they would form a black forest, so in the interest of realism you should be able to craft cuckoo clocks from their wood :D

I found a bug in sectors2sqlite that caused negative y values to be read as large positive numbers. Are you sure the problem was z<0 in your case, and not y<0? I created a patchset to fix the bug I found, would be glad if you could test: https://github.com/kahrl/minetest/commits/sectors2sqlite-fix .

If the build was compiled with RUN_IN_PLACE=0 (i guess that is the case for the Ubuntu packages), the path should be ~/.minetest/minetest.conf. Btw (regarding your other topic) you can set texture_path there too, so you don't have to overwrite files in /usr/share/minetest to change the texture pack.

Are you all saying that the map isn't getting saved when the X button of the console window is clicked? If so, that would be a data loss bug... which could probably be fixed using a few SetConsoleCtrlHandler(...) calls.

Minetest uses the graphics driver's Render to Texture feature to draw all those cubes in the inventory, but this somehow fails on your computer.
