Controlling world generation with script

Bedrock currently supports custom worldgen via data-driven biomes, and it's the only way to modify worldgen. Scripting API should also be allowed to install custom hooks to world generation steps.

 

Example use case:

Let's say we are to add in a new ore block, Copper Ore. It doesn't spawn like iron or gold ore but has a special spawning rule.

• Similar to slime chunks, a chunk has a 20% chance of being copper chunk, regardless of biomes.
• Copper veins can only appear in copper chunks.
• For each copper chunk, a random Y coordinate and a random radius are chosen.
• Stone blocks in a spherical area determined by the chosen values will be replaced with copper ore blocks.

These kind of spawning rules can only be represented as code. Data-driven models only work well for simple cases.

  I was idly considering whether it would be possible and what it would take to port El_Minadero's OreVeins/GeoWorld realistic ore generation mod to Bedrock.  Unfortunately, it's not possible without the ability to alter block generation (or somehow alter blocks in a chunk after initial generation).
