### count = worldedit.set(pos1, pos2, node_name)\r
\r
Sets a region defined by positions `pos1` and `pos2` to `node_name`. To clear a region, use "air" as the value of `node_name`.\r
+If `node_name` is a list of nodes, each set node is randomly picked from it.\r
\r
Returns the number of nodes set.\r
\r
### count = worldedit.copy2(pos1, pos2, off)\r
\r
Copies the region defined by positions `pos1` and `pos2` by the offset vector `off`.\r
+Note that the offset needs to be big enough that there is no overlap.\r
\r
Returns the number of nodes copied.\r
\r
### count = worldedit.stack2(pos1, pos2, direction, amount)\r
\r
Duplicates the region defined by positions `pos1` and `pos2` `amount` times with offset vector `direction`.\r
+Note that the offset vector needs to be big enough that there is no overlap.\r
\r
Returns the number of nodes stacked.\r
