I'm making a mod that adds a node that can be pushed around, moving one block whenever it's punched. It seems to work, but a lot of the time the node moves two blocks over rather than one. I can't figure out why, can someone more experienced look at it? The block only moves if hit from one angle, I haven't done the others yet.

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_node("pushblocks:pushstone", { description = "Test Pushstone", tiles = {"default_cobble.png"}, is_ground_content = true, groups = {cracky=3}, }) minetest.register_on_punchnode(function(pos, node, puncher) if node.name == "pushblocks:pushstone" then if minetest.dir_to_facedir(puncher:get_look_dir()) == 0 then pos.z = pos.z + 1 if minetest.env:get_node(pos).name == "air" then minetest.env:add_node(pos,{name = "pushblocks:pushstone"}) pos.z = pos.z - 1 minetest.env:remove_node(pos) end end end end)

The code is 100% working. The reason for that it moves 2 blocks sometimes is that you punch it twice (once before it moves, second time after it moved), although you don`t release the mouse button.
You could put some timer in or use on_dignode instead. Feel free to ask if you need help in coding that.

you have this bit in twice:

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: pos.z = pos.z - 1

right here:

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: -------------------> pos.z = pos.z + 1 if minetest.env:get_node(pos).name == "air" then minetest.env:add_node(pos,{name = "pushblocks:pushstone"}) -------------------> pos.z = pos.z - 1

which would result in a pos.z decreasing by two

No mauvebic, thats fine. One time it is +1, the other time -1.
I tried the mod and it was possible to push the moving thing just 1 block over.

I think this is due to that the game interpret click mouse button like hold mouse button, and "minetest.register_on_punchnode" counts twice or even triple, if you try click mouse button very shortly, node will move only one block length.

Try add some "wait" command, if is there any.

Edit: Jeija sorry I did not notice your post, which is about the same.
