I want to get the vm index from an absolute coordinate like

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

This doesn't work

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local vi = a:index(pos.x, pos.y, pos.z) data[vi] = c_air

Or how can I get this to work? I'm confused why it doesn't work

Nodes is a list of positions

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: minetest.register_on_generated(function(minp, maxp) local vm1 = VoxelManip() local a = VoxelArea:new({MinEdge = minp, MaxEdge = maxp}) local data = vm1:get_data() local c_air = minetest.get_content_id("air") local c_glass = minetest.get_content_id("default:glass") for _, pos in pairs(nodes) do local vi = a:indexp(pos) data[vi] = c_glass end vm1:set_data(data) vm1:write_to_map() end)

I got it. It only works with

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local vm, emin, emax = minetest.get_mapgen_object("voxelmanip")

Deleted post.

How can I calculate the VoxelManip index from absolute pos?
