-[Mod] nether-pack [nether-pack]
-
-This is a modified version of lkjoel's nether mod.  
-Look here if you want to see the differences:  
-https://github.com/HybridDog/minetest-nether/compare/lkjoel:master...master  
-Sadly lkjoel's one disappeared…
-
-Thanks a lot to LeMagnesium, crabman77, Ombridride, Gael-de-Sailly, ObaniGemini and other people from server-minetestforfun for working on this mod.

-TODO:  
-— find a way to get the perlin noise inside [-1; 1] or use another noise  
-— add something containing items to that buildings  
-— update leaves visual_scale
+TODO:
+* Mapgen: Find a way to get the perlin noise values inside [-1; 1] or use
+  another noise.
+  The problem is visible in the nether forest, where the mapgen code flattens
+  the ceiling if it is very high.
+* Mapgen: Generate more detail inside the simple pyramid-like "buildings",
+  e.g. add a small treasure chest node which contains items

HybridDog	01cd7c8e5b	New nether guide * Remove code which uses the font size setting to position text and images. Instead use Minetest's hypertext formspec element * Rewrite many parts of the guide contents, e.g. "you" -> "we", more detailed portal description * Add a setting to permit viewing it in the overworld (enabled by default) * Update the Readme I have set the font size to 24, which works well for me on a 1920x1080 screen with somewhat high DPI. The text written in hypertext apparently ignores the Minetest font size setting, so it may look bad on different screens.	2022-08-19 18:14:44 +02:00
HybridDog	817efcdd29	Add settingtypes.txt to configure player trapping and message logging There are also some changes to fix problems when trapping is enabled while damage is disabled or the other way round.	2022-08-16 17:25:41 +02:00
