FOSS gamedev and creative worlds

I am making a mod which detects the node above it and if its air it replaces it with a node.

so lets say I have a node (default:dirt) at 0,0,0
when i hit this done (with on_punch) it checks the node at 0,1,0
After this it checks what the node at 0,1,0 and if its air it places a node there (default:dirt)

What i have tried'


The code above works but you cannot put two nodes together since since it looks for the dirt in X, Y and Z

So if i place a node at 0,0,0 then hit it it will place a node at 0,1,0
However if i place a node at 0,0,1 it will detect the node at 0,0,0 and 0,1,0 and not place a node.


I have also the code shown below but it just crashes the game



If anyone knows how to solve the problem feel free to reply.

many thanks

will get the node above pos. you can then do:

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 target_pos = { x = pos.x, y = pos.y, z = pos.z }
target_pos.y = target_pos.y + 1
local node = minetest.get_node(target_pos)

will get the node above pos. you can then do:

if node.name == "air" then

Thanks for the help
