Programmatically get my posn

[basil60]

Hi
can I programmatically get the position of the block I'm standing on in Minetest?
I'd like to work on my first mod to change the block beneath me to another type. Gotta start somewhere!

You can get the position of the a player and then calculate the position of the node below them based on that.

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_joinplayer(function(player)
   local pos = player:getpos()
   pos.y = pos.y-1
   minetest.set_node(pos, {name="default:cloud"})
end)

Thanks Red-001
So if I drop this into a mod, will blocks beneath my "feet" become clouds as I walk?

This will only work when the player joins the game, not when you are walking.

If you want to make it work while you are walking, have a look how it's done for the wielded torch light in the torches mod: viewtopic.php?f=11&t=14359

The basic of getting the player position is to get a reference to the player object. And there are many ways in minetest to get a player reference:
- when it connects/disconnects
- when it interact with a node
- when it uses some tools

All infos are in the api documentation https://github.com/minetest/minetest/bl ... ua_api.txt or in rubenwardy's modding book http://rubenwardy.com/minetest_modding_ ... a_api.html
