Note: The amount of octaves is always fixed at 10. You can't configure less or more than 10. | |||
=== Y-Thresholds === | === Y-Thresholds === | ||
Imagine you had a side view of a mountain and you could make it wider and thinner at any given elevation. This is approximately how the y-threshold system works. terrainYKeyPositions are the relative (0=bottom, 1=top of the world) coordinates and terrainYKeyThresholds define how much Percent of terrain should be solid blocks (0 = always solid, 1 = always air), or in other words it's density. We could also make a graph of this: | |||

| Line 52: | Line 54: | ||
In this example at maximum world height the density is 0, so there will always be air blocks. In the middle we have a jump where the y-position changes, but not the density, so this will create cliffs in the mountain. On the lower end the opposite happens. The Y-Position changes very little but it's density increases a lot. If that position happens to be at the sealevel we would get flat beaches. The default sealevel y-position is 0.43 | In this example at maximum world height the density is 0, so there will always be air blocks.

And below a certain y-position the density is always 1. If we would set that to a lower value, we would get very deep lakes. | And below a certain y-position the density is always 1. If we would set that to a lower value, we would get very deep lakes. | ||
The amount of configurable Y-Thresholds is arbitrary you may use any quantity, just make sure both lists have the same amount of elements. However, it wouldn't make sense to configure more than 256 thresholds for a world height of 256 blocks. | |||
=== Testing Landforms === | |||
You can trial&error landforms very quickly without the need to restart the game every time you made changes to the landforms.json | |||
<ol> | |||
<li><code>/wgen autogen 0</code> - disables automatic generation of chunks</li> | |||
<li><code>/wgen del 10</code> - delete all chunks with a radius 10 chunks (Warning: Cannot be undone!)</li> | |||
<li><code>/wgen regen 5</code> - Reloads the landforms.json then deletes and regenerates all chunks with a radius of 5 chunks</li> | |||
