Get dropped items on step over (like minecraft)

[lkjoel]

New version! It fixes the block going high up into the sky

I promised I'd make this, and I finally did. When you walk over a dropped block (usually with the Q key, not to be confused with placing blocks) it adds it like as if you picked it up manually.
Make sure you have the latest GIT version of minetest, and patch builtin/item_entity.lua as so:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

And then patch item.lua like so:

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

200c200
<               v.y = v.y*2 + 1
---
>               v.y = v.y*2 + 2


This, of course, is based on Jeija's mesecon code.
Here is the full source code (if the patch doesn't work) of item_entity.lua:

[Death Dealer]

awesome new node drop with 3d rotating cube will work very nicely with the timber mod thanks ikjoel your the man:D

[lkjoel]

What does the timber mod do? I never really understood it

[Death Dealer]

drops the blocks from a tree if you cut it in the middle, much like in the real life. basically chopping trees down.

[bgsmithjr]

theres a function for this , the timber mod
default.register_falling_item("default:tree","default_tree.png")
Something like that.

[Death Dealer]

theres a function for this , the timber mod
default.register_falling_item("default:tree","default_tree.png")
Something like that.

and something like that would enable picking up item by walking over them?

No, I said for the timber mod.

i was describing the timber mod to ikjoel-_- im not sure where your going with this..

[bgsmithjr]

sorry, but it was just conversation, what the timbermod does can be obtained with a function in the default, so you don't need a mod or programming knowledge you just add one line, but if you would rather have it as a mod, I understand, sorry to spam the topic

no its ok, i didnt know it could be added so easyly.

oh, I get it

does my mod work?

So which lines do we put this over???

yep worked like a charm thanks ikjoel:D

[z10N30NC1UB10z]

Is there any possible way this mod can work with the 1/22 version?

[Jordach]

Nope, never. Sorry about that.

[z10N30NC1UB10z]

It's alright, thanks for the quick response Jordach.

[sfan5]

Nice!I'll use this

[jordan4ibanez]

https://github.com/jordan4ibanez/minetest
this code and the other one works great! i included it in my git!

[Death Dealer]

to get all blocks to drop nodes themselves would be pretty simple then?? its off topic i know but its relating.. would it be possible to addapt the timber mod to work with all nodes? maybe not in the same fashion just as far as the 3d cube node drop. ill see what i can figure out here: /

[lkjoel]

yeah, this is for all drops

[lkjoel]

NEW VERSION! It adds an "outer circle" that moves the block towards you (like in minecraft)

[Jordach]

@Lkjoel, the last Win build works with your full source code. 2012/04/08

[lkjoel]

New version! It fixes the block going high up into the sky

[Jordach]

Oh god, that bug........
