| Summary | 0000142: Volcanoes' left sides can protrude buggily above slopes -- height check not symmetrical? |
| Description | Compared to 40d, volcanoes now retain the same shape every z-level, and the obsidian barrier that, in 40d, would extend a few tiles outward from the volcano is now only 1 tile thick. This may or may not be by design, so I'm not sure if it is a bug or not.
Volcanoes whose rightmost edge is at the TOP of the mountain extend above ground, whereas volcanoes whose rightmost edge is at the bottom of a slope (mostly) correctly create a "pit" on the rest of the upward slope |

Confirmed on two worldgens and two fortresses with a volcano. |

Confirmed. Also, the magma chamber stays vertical even when the mountain leans, making said chamber stick out of the ground like a giant obsidian tube filled with magma |
|
|
|
|
|
I would also like to add that in the few worlds I have generated (3 smaller, 1 medium), each world had only 1 single visible volcano in the entire world. |
|
|
|
|
|
Confirmed, from Z level 54 to z level 156 I have a nice tall lava pipe, which holds exactly the same shape at every single level. It may even extend further down but some sort of obstruction I can't actually see interrupts my view of the pipe at the bottom 20 levels or so. |
|
|
|
|
|
The obstruction is the magma sea. |
|
|
|
|
|
Confirmed. For some fun before it (likely) gets fixed: puncture the tube. Flood the world with magma. |
|
|
|
|
my first guess would be that it is the magma sea yes, but since I didn't go down there to look and reveal was crashing on me, I didn't say for sure.
What was funny to me was that after 30 or so level down, I stopped being able to see the walls of the pipe, only the magma. |
|

I think I have figured out the cause of the volcano tubes that extend out of the ground like a straw!
Volcanoes whose rightmost edge is at the TOP of the mountain extend above ground, whereas volcanoes whose rightmost edge is at the bottom of a slope (mostly) correctly create a "pit" on the rest of the upward slope.
My guess is that when the volcano gets placed, somewhere the algorithm mistakenly uses the x-coordinate rather than the z-coordinate to determine how deep the volcano tube should be.
I hope this gets fixed - it is a real deterrent from starting on volcanoes for reals (that is to say, I cannot resist puncturing the tube and watching the forest flood with red goo). |

|
|
|
|
On a related note, it seems the actual number of volcanoes never goes over the "minimum volcanoes" value when creating the world, so if you want more than 1 you have to turn that value up. |
|
|
|
|
|
The tube being the same shape all the way down makes tapping it to actually use for anything other than hot, hot death rather difficult. |
|
|
|
|
|
Sadly, this bug is still around. Makes life much harder if you want to work with magma. |

Is the issue you described at 0000142:0002579 still present? |
