on_construct is not called when using VoxelManip

[ArguablySane]

I'm trying to set metadata for some nodes when they are generated. The dev wiki suggests using the on_construct callback, but unfortunately that doesn't seem to work if I generate them using a VoxelManip during mapgen. For now I'm having to set the metadata manually in the mapgen code.

Is this by design, and is there a nicer way to solve the problem?

This is by design as the VoxelManipulator needs to be fast, and so doesn't call callbacks. In order to solve this, you could manually call the on_construct from the manip loop. minetest.registered_items["name"].on_construct(pos, minetest.get_node()), but you should try to minimise this. Running the code in the loop rather than calling on_construct would be better, or running it at a later date.

Yeah, I suspected that might be the case. Thanks for letting me know anyway.
