[1.16.5] overwriting the maximum build height

[Nyko]

I'm currently writing a mod in which I change vanilla features and add a few new features (from version 1.17).

now I want or try to enlarge the world size (height).

since i have no idea if this is possible and if so.

which I would then have to overwrite. my goal would be to expand the world by 128 down (to -128) and 64 up (to 320).

I assume that the whole thing will not be easy because I have to overwrite the whole world generation (ores, caves, decoration, etc).

World generation is your smallest problem. The save format doesn't support this in 1.16, so you basically can't.

it is possible to create a custom save format

Edit: or copy one from a old version like 1.15

Not easily.

And older save formats don't support an increased world height either.

(In fact, I'm pretty sure the current save format goes back to like 1.7. Edit: just checked, Anvil has been in use since 1.2.1)

thanks for the info, since the whole thing sounds pretty complicated, I will probably not change it

Minecraft 1.17 update is out and the Forge version is finally out too,
vanilla's datapack makes it possible to change the height of the world, is this also possible for a mod?

if it is possible how do i change the height?

yes it is possible you have to overwrite the dimension-type file of the dimension in which you want to change the height (the values min_y and height)

can I only use the vanilla values, so like y_min=-64 and height=384 or its possible to create a larger world?
so like y_min=-256 and height= 512?

yes you can create a world with max size 4112 (i think), so y_min=-2056 and height=2056
but the values you set in y_min or height should be:

value % 16 == 0

if this is not the case minecraft will use the default values so like y_min=0 and height=256

where do I have to put the file (overworld.json)

thanks work perfect

[Nyko]

sorry, for asking but is it possible that the VerticalAnchor only work in the positive direction,
because i move currently my features into the new world height (-1024<->1024)
and if the VerticalAnchor is negativ they will not generate

very simple, move the world into positive direction so form -1024<->1024 to 0<->2048

omg i stupid
Another question what is the difference between Decoratable#rangeUniform and Decoratable#rangeTriangle

[Luis_ST]

Just now, Nyko said:

Decoratable#rangeUniform

generates the feature between the first and second value

Decoratable#rangeTriangle

generate the feature in a triangle like the new ores
like that:

so that would generate the feature like the coal ore in the picture:

.range(new RangeDecoratorConfiguration(TrapezoidHeight.of(VerticalAnchor.absolute(0), VerticalAnchor.absolute(192), 96)))
