questions about singlenode mapgen

[RHR]

1) How long are nodes like sand or dropped items falling in singlenode mapgen? Infinite or are they removed after a certain time?
2) How far does flowing water/lava fall? Infinite?
3) Is there a diffence between air nodes and other nodes if they get saved?

2) Until it reaches the ground; maximal 64k nodes
3) air is saved - ignore isn't

thx that was fast :D
@3) what is the difference of air and ignore?

@3) you can walk through air and replace it with another node. ignore is solid and used to stop you walking into not loaded areas

Ok! Thank you very much! :)

I have questions about singlenode myself.

Why do nyan cats spawn for? Isn't it supposed be nothing? and why some areas are darker then others?

That all I got really.

[Wuzzy]

Nyan Cats are spawned by the mod “default” of minetest_game, not by the map generator itself.

I cannot answer the other question. Maybe because of a bug? lol

[paramat]

Cats are spawned because they're cool, and transcend all dimensions.

And it's not possible to trace the meows of the mapgen by overriding default.make_nyancat. l tried it and still don't know the reason.

Another question:
Is is possible to force the mapgen/game not to replace ignore nodes with air? In other words: Is it possible to force a area to keep unloaded like the sky above the cloud layer?

[Krock]

Once an area is generated, it doesn't matter how it's filled.
The sky above cloud layer is loaded like any other block.
You can use a new function to delete a specific mapblock

Doesn't item_entity_ttl only limit the time for item entities only? So I guess this does not apply to falling nodes, because they are not item entities. Right?

I thought he meant dropped stacks which fall down.
It would require an addition of 4 - 8 lines of code to add a maximal age for falling nodes.
