What it does
Swap one block type for another inside a box, leaving the rest. At most 4096 blocks a run. It's a step: it runs when the white wire reaches it, then the flow carries on from its Then pin. It gives 1 value later steps can use. Find it under World & blocks in the palette.
When to use it
Use it when the flow needs to: swap one block type for another inside a box, leaving the rest. At most 4096 blocks a run.
When not to
If nothing should change in Discord, a value node or a check is lighter.
Typical wiring
Sockets: settings you can wire
- From Location
-
One corner: wire a location in, or type world x y z.
What goes there: Type it in the side panel, or wire in a location. e.g. world 10.5 64 -3.2
If it's empty: Optional. Left empty and unwired, the step runs without it.
- To Location
-
The opposite corner, in the same world.
What goes there: Type it in the side panel, or wire in a location. e.g. world 10.5 64 -3.2
If it's empty: Optional. Left empty and unwired, the step runs without it.
Values it gives
- Changed Number
-
How many blocks it swapped. e.g. 12
If it's empty: Empty when the step didn't make one (it stopped early or was skipped); steps reading it get nothing.
