FOSS gamedev and creative worlds

Hi there,

there are many bugs with the nether. Mining ores is almost impossible and the mobs are very buggy in the nether. Nothing is indicated in the debug.txt. I had the Stampy game (Morn76's subgame). I've spotted no bugs in the overworld but Minetest becomes very laggy after 90 minutes of gameplay.

It's necessary to report these bugs to improve Minetest.

Thanks in advance.

What do you mean? Does it take too long? You'll probably need to craft a more powerful pick axe.

What exactly do you mean by buggy? Do they crash Minetest, or do that act weird?

This is problem that occurs in most in development video games. The slow down is usually from "memory leaks", where the game takes up more and more memory because it forgets to free it.

The only thing I can suggest is to just restart Minetest :(

For other people viewing this topic, this is the nether mod in stampy game: viewtopic.php?id=5790

The mobs are supplied by a modified version of Simple Mobs: https://github.com/mdoege/stampy_game/t ... /mods/mobs

The problem with my fork of PilzAdam's Nether mod is that it takes some time to first generate the "Nether cave" around the portal. Probably at least 30-60 seconds, during which time you will teleport back and forth between the Nether and Overworld a few times (which looks buggy but is not easy to prevent).

When terrain generation is finished, there is still some lag while lava flow and lighting updates. So yeah, for the first 5 minutes or so the Nether is unusably laggy.

But once lava and lighting updates are complete, the Nether is fairly usable, i.e. you can mine ores and fight mobs normally. But this takes some time, it's not like in MC where you just go the Nether and *boom* you can use it after a few seconds.

Lua mapgens are slow, that's the problem…

Lua mapgens aren't slow, set_node is. LVM would make it almost as fast as C++.

It is using the Voxel Manipulator already. And the lava fluid updates are done by the C++ engine. There is simply a lot of flowing lava there.

I tried mining with a diamond pickaxe but nothing. It's hard to kill mobs in the nether because of these bugs but the game don't crash. The game needs a auto free memory. Can I play with DirectX 9 and 10.1 or only with OpenGL?

I believe you can play with DirectX, but I've never used it. To change it, I think you need to go to the settings tab, then open the dropdown menu under rendering, and select DirectX

It's without conflict with the mods?

Lizzy wrote:It's without conflict with the mods?

afaik, yes. You can always change it back if it's not.

So...the only bugs I have is with the nether. I will return to Minetest in near future.

Are you sure ? I see the ores replacements here. Look at this : nether voxelmanip branch.

True, it still does the ore replacement thing. But creating the Nether landscape and lava lakes is done in Voxel Manip and that is probably still where most of the lag comes from I think.
