Caveins

[rye130]

Has anyone done any extensive testing with the cave in system? I have been doing a little, and have made some assumptions on how to avoid them but then I get caveins when I assume I shouldn't

My general knowledge is it is safe to mine 3 tiles deep (meaning 2 mined tiles behind you) hence why the zig-zag pattern works. Now I'm starting to believe that it is more about how many tiles around the tile you are mining have been mined or how many tiles around you are mined.

Anyone find any more information and care to compare notes?

I tried that zig-zag method and had several cave-ins... I don't know if I did something wrong or if it doesn't work.

It works.

This may sound ridicously stupid, specially with that thing on top.
| = Wall
xxx = The wall where I started to mine
ooo = The single tile that appeared after mining the wall
Y = Places where I got a cave-in.

Basically I did 1 tile, then jumped in and mined the one on my right, BLAM cave-in.

I thought that shouldnt be normal (at least, it wasnt 2 straight tiles or something like that, it was just a diagonal one from the wall).

Maybe I'm just throwing noob data, but that was my last "research" lol.

Mining a tile is safe if the total count of mined tiles in any direction around that tile in question is below 4.

Code: Select all

 [#] = already mined tile, [X] = wall, [_] = wall in question to be mined

So mining in a straight line will be safe till the 3rd tile.

Code: Select all

                [X]
Safe : [1][2][3][_][X]
                [X] 

                     [X]
UnSafe : [1][2][3][4][_][X]
                     [X] 

If on the other hand there are mined tiles in any other direction you have to keep the total count below 4 aswell.

Code: Select all

          [2]
Safe : [1][_][X]
          [3] 
                  
            [2]
UnSafe : [1][_][X]
            [4]
            [3] 

Only an assumption, but pretty sure with that one.

Most likely it is also dependant on whether you're already standing on a mined tile or still on cave ground, since it's always safe to mine the first row of rock while standing on cave ground, whereas mining the same tile standing on a mined tile results in a cave in sometimes.

EDIT: Considering my last sentence it is highly likely that it indeed matters how many tiles around the PLAYER are mined, not around the wall.
So take yourself as center of the evaluation, if the accumulated count of all tiles in every direction is below 4, including the one you're standing on, you'll be safe.

EDIT II: Might wanna check if the zig-zag works with any more tiles mined in one direction than one, if it doesn't work it means that not only the tiles in a straight line around the player matter, but the tiles diagonally aswell.

Lol, me, too. Luckily I didn't get smashed.
