Offset (Meta Condition Type)

Tests a block condition at a position offset from the one being checked. It is a block condition only, with no entity or item equivalent, because only block conditions have a position to offset from.

Type ID: apoli:offset

Fields

Field	Type	Default	Description
`condition`	Block Condition Type	required	The condition to test at the offset position.
`x`	Integer	`0`	Blocks east.
`y`	Integer	`0`	Blocks up.
`z`	Integer	`0`	Blocks south.

Examples

Is the block above this one air? That is the usual check for room to grow (the minecraft:air block tag covers cave air and void air too):

{
  "type": "apoli:offset",
  "y": 1,
  "condition": { "type": "apoli:in_tag", "tag": "minecraft:air" }
}

Grass with air above it, combined:

{
  "type": "apoli:all_of",
  "conditions": [
    { "type": "apoli:block", "block": "minecraft:grass_block" },
    {
      "type": "apoli:offset",
      "y": 1,
      "condition": { "type": "apoli:in_tag", "tag": "minecraft:air" }
    }
  ]
}

Offsets nest, so you can reach diagonally or several blocks out:

{
  "type": "apoli:offset",
  "x": 1,
  "condition": {
    "type": "apoli:offset",
    "y": -1,
    "condition": { "type": "apoli:block", "block": "minecraft:water" }
  }
}
