This mod adds a 3D ladder to the game that will extend 5 nodes high each time it is punched.



It will not destroy blocks in its path, however it will still place the nodes if there is empty space beyond the obstacles.

So basically you need a ceiling of 5 nodes thickness to stop the ladder from expanding.


Players can rotate with screwdriver 2 clicks and punch should work to destroy it (most of the time)
Tnt works pretty good too...

I dont have a craft recipe yet so you will have to use the giveme command to aquire it in the game.

Nice idea.
I noticed that you can not destroy the ladder because it keeps placing more.
If you add get weilded item then the player has to hold the ladder when punching to make it grow.

Change line 48 to

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

      if node.name == "jacobs_ladder:ladder" and
    puncher:get_wielded_item():get_name() == "jacobs_ladder:ladder"then

Thanks Don, Its no longer a cursed item!

I hope you don't mind me helping. I am not good with lua but like to help when I can.

To get the ladders to face the right direction you can do this
Change line 86 from

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

function growblock(blockName, targetHeight, pos)

to this

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

function growblock(blockName, targetHeight, pos, puncher)

And then you change line 93 from

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.env:add_node(p, {name=blockName})

to this

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.env:set_node(p, {name = "jacobs_ladder:ladder", param2=minetest.dir_to_facedir(puncher:get_look_dir())})

I dont mind the help at all..I need all I can get !

But if you make those changes to the lua it crashes game;
you also have to change line 52
from: growblock(node.name, targetHeight, pos)
to: growblock(node.name, targetHeight, pos, puncher)

But I dont see any differance myself in how the node is placed;
so long as its an open area they go right where I want them with and without the changes.

But when in a single node open shaft where its cramped, placement is kinda messed up
with and without the changes.

I will keep testing these changes though.

Thanks for the help man!

I did it to my copy and it worked fine. The ladders are placed in the direction that you are facing.
I am using the latest minetest dev from 2 days ago. The version shouldn't matter.

Here is my copy.

Haha you forgot to mention you changed line 52 in your instructions :)

Anyways,it works the same for me with or without the additional code you provide.

[Don]

That's weird. They facedir properly for me. Maybe someone that knows more than me can make it work.

[Napiophelios]

Okay I think I see what you are talking about now.
I have updated with your code changes in revision 004.
Thanks Don.
