--- Sets the given parameter to the given value.

-- This function would pair well with worldeditadditions.nodeapply.

-- @param pos1 Vector3 Position 1 of the define region to operate on.
|
|
-- @param pos2 Vector3 Position 2 of the define region to operate on.
|
|
-- @param param string="param|param2" The name of the parameter to set. Currently possible values:
|
|
-- - **`param`:** Param1, aka the node id.
|
|
-- - **`param2`:** The supplementary parameter that each node has. See also <https://api.minetest.net/nodes/#node-paramtypes>. The node type is set by the mod or game that provides each node in question.
|
|
-- - **`light`:** Sets the light value of all nodes in the defined region.
|
|
-- @param value string|number The value to set the given parameter to. If `param` is set to "param" and `value` is a `string`, then `value` is converted into a number by calling `minetest.get_content_id()`.
|
|
-- @returns bool,table|string true,statistics_table OR false,error_message.
