jigsaw-facing
warning by default
A jigsaw block that can never join its target: every jigsaw block with its target name in its pool faces a way it cannot meet. The game turns pieces only about the y axis, so a block facing up joins only one facing down, and a sideways block only a sideways one.
Changing it
Set the rule's severity in mms.json, to error, warning, info, hint or off:
{
"lint": { "jigsaw-facing": "off" }
} To silence it on one line, write // mms-ignore jigsaw-facing on the line or the line above. See Lint rules in the guides for more.
