[Mod] The Origin [1.3.1] [origin]

[Wuzzy]

This is a very simple map generating mod for the map generator “singlenode”. It places a single indestructible block, called “The Origin” directly below the spawn position. It also forces the map generator to be “singlenode” unless disabled via settings.
This prevents the player to fall immediately down on spawning.

Screenshot:


By default, the block will spawn at (0,-1,0), but if the setting “static_spawnpoint” is present, it will spawn the block one node length below that position.

I am unsure if this mod is capable of handling a static_spawnpoint which is changed often. The intention is that the block only spawns once for the entire lifetime of the world and that's it. If you somehow noticed that a second origin block spawned, please report it here as bug.

I consider this mod to be finished.

Well, it's possible to create multiple origin nodes if static_spawn is changed to a not generated coordinate.
This mod can be helpful for people who want to create their own world.
Could you add some nodes around the origin, so it's not possible to fall off by a mistake?

[Wuzzy]

Thanks for the feedback. I made a small update to version 1.1.0.

This mod now writes a file “origin.mt” into the world folder when the Origin is first placed. If the file is present when the world is loaded later, the mod will not place the Origin again.
I hope this ensures the Origin will only be placed once in the world.

I also added a short readme file.

Hmm, I am not sure if I change the stuff that spawns around the spawn position. I don't want this initial block to get in the way too much. For now, if you fall down, you could teleport back with /teleport. Not the best solution …

Maybe I will extend this mod later to spawn more fancy structures at the spawnpoint, and make this mod more configurable. But for now I keep things just simple and stupid. :D

Quick bugfix release 1.1.1!

The origin node could theoretically be removed by the cave generation of the map generator. Now this should not be possible anymore.

[Sokomine]

Good idea. Falling through the map when mapgen is singlenode is always a bit annoying. It takes some time to type the /grant singleplayer all command. There are also some skyblock games which are pretty nice.

I just released version 1.2.0. This is a minor update which adds mod.conf and tweaks the readme file a bit.
I also added a Git repository (see first post).

I'm sure you can add this easily yourself but I'd be more than happy to add the simple code but I made a modified version of your Mod that defaults to the singlenode mapgen. Just kinda makes sense :) Thanks for this mod!

[Wuzzy]

Since the singlenode mapgen is now deeply hidden in Minetest and hard to select, should I change this mod that it automatically forces the singlenode mapgen on loading?
Or is there maybe an usecase for an origin block in any of the other mapgens?

[TheReaperKing]

Maybe if you are worried about people wanting a choice you could make it called "The Origin + Singlenode Mod" Here is what I have. I did make the block destructible because in case I need to destroy it when building.

Edit - In case you were wondering why I changed your license to DWYWPL I work at a school :) Same license but actually offers you some protection from getting sued too.
