Syntax
minetest.get_content_id(name)
Description
Returns an integer: the internal content ID of name
Example
local c_air = minetest.get_content_id("air")
print("Air has the content id: " .. tostring(c_air))
local manip = minetest.get_voxel_manip()
local emin, emax = manip:read_from_map(minp, maxp)
local area = VoxelArea:new({MinEdge=emin, MaxEdge=emax})
local data = manip:get_data()
for z = minp.z, maxp.z do
for y = minp.y, maxp.y do
local vi = data:index(minp.x, y, z)
for x = minp.x, maxp.x do
--remove all nodes in the area - set to air
data[vi] = c_air
vi = vi + 1
end
end
end
