==INSTRUCTIONS==
|
|
1) Make sure avgcolors.py outputs the usage instructions
|
|
2) Add the dumpnodes mod to Minetest
|
|
3) Create a world and load dumpnodes & all mods you want to have a color entry for
|
|
4) Execute /dumpnodes ingame
|
|
5) Use the command to generate colors.txt (obviously don't forget to replace /path/to/... with the actual path)
