Chunk Generator Block Pop Section

In this section, we can decorate our chunk.
This section is called once per chunk.
This step is the last step in chunk generation. When this is called, blocks/biomes have been determined.

AVAILABLE SYNTAXES:

Let's talk about some of the available expressions/effects we have that work in this section.

Highest Block Y Expression:

chunk[ ]data highest [block] y at %vector%

This expression allows us to grab the highest block Y at a specific coords.
We can use this to determine where to place a structure or grow a tree.
NOTE: The vector represents a chunk position (0 to 15), not a world position.

ChunkData Biome Expression:

chunk[ ]data biome at %vector%

This expression is used to determine which biome is located at a specific position.
You can use this to determine which blocks/structures to place based on biomes.
NOTE: The vector represents a chunk position (0 to 15), not a world position.

ChunkData BlockData Expression:

chunk[ ]data block[data] at %vector% 

Represents BlockData of blocks in a ChunkData.
This can be used to get/set BlockData when decorating your chunk (ex: trees, bushes).
NOTE: The vector represents a chunk position (0 to 15), not a world position.
You CAN reach into neighbouring chunks by going below 0/above 15 in the vector.
I'm unsure how far you can reach, so use this liberally.

ChunkData Structure Place Effect:

place chunk[ ]data structure %structure% at %vector%

This effect allows us to place structures in our chunk.
This differs from the standard effect for placing structures as it doesn't take in a location.
NOTE: The vector represents a chunk position (0 to 15), not a world position.

Populate Tree Effect:

populate %bukkittreetype% at %vectors%

This effect allows us to populate trees in our chunk.
NOTE: The vector represents a chunk position (0 to 15), not a world position.

Caution

Do NOT use Skript's grow tree effect in this section. It will crash your server.

EXAMPLE:

In this simple example, we're randomly placing a structure in the chunk.
(The structure is loaded earlier in an on load event)

block pop:
	chance of 25%:
		# We start off by getting the x/z of a random block in the chunk
		set {_x} to (random integer between 0 and 15)
		set {_z} to (random integer between 0 and 15)

		# We will grab the highest Y so we can determine where to place our structure
		set {_y} to chunkdata highest y at vector({_x}, 0, {_z}) + 1

		# We can now use this data to get the biome of the block where we want to place a structure
		set {_biome} to chunk data biome at vector({_x}, {_y}, {_z})
		
		# We can now place a structure at this location
		# We can change the structure based on which biome we have here
		if {_biome} != desert:
			# Example of populating in all biomes that are not desert
			populate cherry tree at vector({_x}, {_y}, {_z})
		else:
			# Example of populating a structure in a desert biome
			place chunkdata structure {-structure::stone_blob} at vector({_x}, {_y}, {_z})
