You REALLY should add in the description that this mod adds a new ore that needs to be mined in order to use ANY of what is in this mod.

Because I don't want this mod if it adds another ore, especially when my game is already running. So now I have to remove it again just shortly after adding it -.-

I found out by accident that another mod called "Deep Mining" will help generate this new ore "Tenemut" that is needed by the Dark Matter mod, if you have started a game already. Once you get some tenemut in this way on an existing map, you can start the entire research and production chain related to Dark Matter.

However, as you said, by itself, the tenemut deposits might only appear on new, unexplored chunks (however, I am not sure of this. It works this way for some ores that are added in the middle of a game.

you can spawn in the ore with:
/c local surface = game.player.surface; local ore = nil local size = 5 local density = 10 for y=-size,size do for x=-size,size do a = (((size+1) - math.abs(x))10) b = (((size+1) - math.abs(y))10) if a < b then ore = math.random(((adensity)-(a(density-8))),((adensity)+(a(density-8)))) end if b < a then ore = math.random(((bdensity)-(b(density-8))),((bdensity)+(b(density-8)))) end surface.create_entity({name="tenemut", amount=ore, position={game.player.position.x+x, game.player.position.y+y}}) end end
