20:35 dievri      hello
20:37 dievri      I trying to draw a filled circle. But if it's to big, just parts of them a drawn
20:37 MTDiscord   <12W​arr1024> you have to sharpen your pencil if it wears down
20:39 dievri      I mean, with blocks and math formula
20:40 sfan5       how exactly?
20:41 dievri      for zed = -radius, radius do
20:41 dievri      for eks = -radius, radius do
20:41 dievri      if (eks*eks) + (zed*zed) <= ((radius * radius) + (radius * 1.2)) then
20:41 dievri      minetest.set_node({x = x + eks, y = y, z = z + zed}, {name="default:dirt"})
20:41 dievri      end
20:41 dievri      end
20:41 dievri      end
20:41 MTDiscord   <12W​arr1024> what kinda radius are we talking here?
20:41 MTDiscord   <12W​arr1024> like, 10? 100? 1000?
20:42 MTDiscord   <12W​arr1024> if you try to set_node outside of the loaded areas then it won't work
20:42 dievri      up to 100, various
20:42 MTDiscord   <12W​arr1024> 100 radius is probably large enough to hit unloaded areas
20:43 dievri      than, what should I do?
20:43 MTDiscord   <12W​arr1024> you can detect unloaded areas because they have "ignore" nodes in them even though they're not past mapgen_limit
20:43 sfan5       althought more complicated, try using a vmanip
20:43 MTDiscord   <12W​arr1024> you basically have to wait and then fill those areas once loaded
20:43 MTDiscord   <12W​arr1024> you can try to force-emerge them but that doesn't stop you from having to wait, I'm pretty sure
20:43 MTDiscord   <12W​arr1024> AND it can probably bog things down a lot
20:44 MTDiscord   <12W​arr1024> is this going to be based on some kind of in-game event or do you want circles filled right at map generation time?
20:44 MTDiscord   <12W​arr1024> doing this as lua mapgen seems like a sane way to do it.
20:44 MTDiscord   <12W​arr1024> if not, like if you have a "circle drawer tool" that draws a huge circle when you use it, you'll have to find a way to store any cicles you couldn't complete, and check them when mapblocks are loaded
20:45 MTDiscord   <12W​arr1024> I don't know of a way to detect when a mapblock is loaded.  There are Loaded Block Modifiers, but unlike the name suggests, they work on NODES, not mapblocks
20:45 dievri      circles with be created by chat command
20:45 MTDiscord   <12W​arr1024> so you need to be certain that there's at least one of a certain node inside each mapblock to be affected, and then any duplication would be at least a little inefficient.
20:46 MTDiscord   <12W​arr1024> congrats, I feel like you've got yourself a Hard Problem :-)
20:46 MTDiscord   <12W​arr1024> you can detect mapblocks being loaded by polling, if you have a list of all mapblocks that you need to modify
20:50 specing     just draw the circle, then turn on fast, noclip and fly and run around it
20:50 specing     then draw again
20:50 specing     problem=solved
20:51 dievri      how can I get a list of all mapblocks that I need to modify?
20:53 MTDiscord   <12W​arr1024> you just need to know 1 node position for each mapblock to test for ignores.  mapblocks are 16x16x16, and it doesn't particularly matter which node you test, it'll be all or nothing
20:54 MTDiscord   <12W​arr1024> It is basically not possible to instantly fill in a space that's larger than the loaded area, so you'll have to do it piece at a time.  It should be possible to make it happen automatically once you've issued the command, though it might not be particularly fast.
20:55 MTDiscord   <12W​arr1024> The ony alternative that I know, that would make it happen "instantly" from an in-game perspective, would be to shut down the server and modify the database directly.
20:56 dievri      Right now things look complicated for me :0, so I need to brake them down bit by bit
21:09 MTDiscord   <12W​arr1024> easiest thing to do is before filling the circle, check and make sure there are no ignores in its area, and if you find any, reject the command and tell the player "radius too large, try something smaller"
21:10 MTDiscord   <12W​arr1024> then you just need to do the detection part, not the queueing part
21:10 MTDiscord   <12W​arr1024> see how ambitious you feel after having done that...
21:11 dievri      right now, the circle is not being fully drawn even If I fly around
21:24 MTDiscord   <12W​arr1024> That's right.  It's because at the time you try to draw it, some areas are not loaded and thus can't be modified, and you're only trying the one time, so if it partially fails, you aren't retrying it later when those parts could succeed.
23:44 Darkwar     hello i making a new server and once i upload i want advertises it but idk where and anwers?
