Blockscript is an open standard file format for storing a region of a Minecraft world for the purpose of serialization and storage of the region in plain-text.
Blockscript is a list of different instructions seperated by a comma (Example: step-1,step-2).
x:y:z=namespaced_id
This instruction represents a single block in the Minecraft world.
The x, y, and z values represent the coordinates of the block, and the namespaced_id represents the type of block (Example: minecraft:dirt). To specify multiple blocks, separate each block with a comma.
To save resources, the fill syntax can be used to fill multiple blocks with the same type of block. The schema for the fill syntax is as follows:
x1:y1:z1>x2:y2:z2=namespaced_id
This instruction represents a rectangular area of blocks with the same type.
The x1, y1, and z1 values represent the coordinates of one corner of the rectangle, and the x2, y2, and z2 values represent the coordinates of the opposite corner of the rectangle.
