Make your stone generator produce multiple block types

Understand the weight system

CobbleGen uses a weighted random selection. Each block type you add gets a weight value—blocks with higher weights are selected more often. The actual probability is calculated as each block's weight divided by the total of all weights.

Configure multiple outputs

Add multiple [[cobblegen]] entries to your cobblegen.toml file, each with a different id and weight:

`

[[cobblegen]]

id = "minecraft:stone"

weight = 70.0

[[cobblegen]]

id = "minecraft:deepslate"

weight = 20.0

[[cobblegen]]

id = "minecraft:granite"

weight = 10.0

`

Test and adjust

Run /reload to apply changes. Let your generator run for a while and observe the output ratio. If you want more variety, lower the dominant block's weight or increase others. If one block should be rare, give it a much lower weight value.
