minetest.bulk set node

Description

 * Set node on all positions set in the first argument.
 * Faster than set_node due to single call, but still considerably slower than Lua Voxel Manipulators (LVM) for large numbers of nodes.
 * Unlike LVMs, this will call node callbacks. It also allows setting nodes in spread out positions which would cause LVMs to waste memory. For setting a cube, this is 1.3x faster than set_node whereas LVM is 20 times faster.

Parameters
For node specification or position syntax see minetest.set_node call. Note that  is a table, not a string (see node).
