[Mod] Tunnel Boring Machine [0.4 beta] [tbm]

[Bas080]

aldobr, you can use the on_construct function for getting the position. Something like

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


on_construct = function(pos,node)
      --regenerate plant only if exact location is not compromized
      minetest.after(1, function()
        local p = {x=pos.x,y-1=pos.y,z=pos.z}
        local b = minetest.env:get_node(p).name
        if (b ~= "air") then
          minetest.env:add_node(p, node)
        end
       
      end)
    end,

Bas80 i know that i can get the position information from the on_construct.

But i cant pass that information to a timer...

Do a simple test, try implementing this with a timer and figure the complexity by yourself.

Nice work with the textures and nodebox...

It needs the facedir parameter to decide in wich direction to dig...

I can fake the facedir parameter with a metastring... pls upload your work somewhere so i can see it

[Bas080]

aldobr, i have a working example of the tbm using minetest.after()

That means that you are not required to stand near the tbm in order for it to keep on digging. Big win for large mining operations! With some changes to the formspec and placing items not on ground but in a chest this should improve performance and functionality. I will work on this today.

EDIT:
init.lua using the minetest.after



What is the essence of this mod? Should it place rails, torches and cobble floor or should this be configurable? What if i want to make a wood floor and no rail. I think this needs a formspec where one can determine the nodes that should be used and in how many cycles it should spawn.

[Bas080]

Hybrid Dog, Ignore my offtopic pm. It's part of my plants mod that supports PilzAdam's farming mod.

I am changing the formspec to support an inventory where the digged nodes will be placed. Also working on supporting nodes that do not have a drop defined.

Anyways, I like the nodebox. however would be nice to have one that span almost all three blocks that the tbm digs.

edit:typo

[aldobr]

Bas080 what happens when the TBM is outside player radius ?

It goes on indefinitely ?

What happens if it touches a unloaded map chunk ?

Player position information is lost, thats why i used an ABM.

aldobr, the distance to which it digs is limited by the resources that are required to dig. Rails. cobble, torches and coal. I have edited the formspec to allow only one slot per resource and the rest an inventory to which the digged nodes are moved. THey are no longer dropped on the ground

I haven't got a download because it'sso simple but if you have pushable_blocks installed then you can get it to place monorails instead of normal rails. pushable_blocks adds 2 carts, 4 tracks and a couple of other things.Try it!

Does anyone have the code for the latest version of this mod? I tried the original link but it appears the site is down. Thanks.

[Topywo]

Afaik there was only 1 version:

[aldobr]

Something wrong with the version you posted..

[Topywo]

Something wrong with the version you posted..

The link or running the mod?

I downloaded it when you posted it but did not change it.

[aldobr]

the lua script is incomplete

[basilgohar]

Does anyone have a copy of Bas80's init.lua file? The link to the Ubuntu pastebin has apparently expired. I can craft the tbm block, but attempting to click on it to load it with it's starting materials causes a lua error and Minetest crashes to the startup screen. I am using Minetest from git as of today.

Thanks, I'll try it out.

[basilgohar]

It's working great, Bas80. Thanks!

[basilgohar]

Okay, in the version I got from Bas80, I've observed two bugs, at least one of which I saw elsewhere in this thread.

The first bug is the one where sometimes the machine only bores a single node, instead of nine, when going forward. Someone else commented that that seemed to be the case when the player was not near the machine while it was working. My observation somewhat confirms this, though I haven't sat there watching it long enough to rule out the possibility of it happening even when close-by and watching.

The second bug I've observed is that periodically, the machine will just change direction, for a reason I cannot yet determine. This can be either a 90 degree or a 180 degree turn (though I cannot rule-out 270, there's not really a way to tell that apart from a 90 degree turn). When the machines are placed next to each other, such that they clear our a contiguous area, then the "turn" happens the same time for both, and it's always 90 degrees. If they are spaced out such that they is a 1-node gap between the cleared areas, then the turn is always 180 degrees.

I haven't delved deeply into the code yet, as I've very little experience with lua, but I plan to take a closer look as I get more time. I just thought I'd bring up these issues first in case anyone knows of them and/or has a version that has them fixed.

Moving forward, is anyone interested in hosting this on Github? If no one else, then I will consider doing it, but I might just make a new version in that case, since I don't know who owns which parts of the code at this point.

[Bas080]

basilgohar, i don't mind if you host. Don't forget to say who made what. The nodebox/textures and those who contributed to the code.

Yeah, I guess the "who made what" part is what may be confusing. I might get a chance to look at it this weekend, since it's longer than usual. Alternatively, if I'm feeling ambitious, I might just write-up my own version, as I have a different idea that I might like to pursue. Assuming I don't have too much difficulty figuring-out lua. :)

Greetings. I am using the version of this mod re-linked by Topywo above. Nice mod, BTW.

I am posting this message because I also use several other mods, including the GloopTest modpack which includes Kalite as a coal substitute and Kalite Torches. For my personal singleplayer use, I cloned the init file for the tbm and modified it to use kalite lumps and kalite torches instead of coal. This does not replace your work.. instread it adds a second tbm machine (tbm:kbm instead of tbm:tbm) to the crafting menu.

If you are interested, I can post the modified file.

I also have plans on making other configurations with different behaviors... which I will be more than willing to post as well when they are done.

Thank you for your work on this mod.

Peace
UOAbigail

Hello,

I tested Bas080's version but I have this error. (Minetest 0.4.10)

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

22:35:31: ACTION[ServerThread]:  tried to dig default:stone at protected position (-56,4,-238)

And Minetest crashes.

protected position. Arent you using an area protection mod ?

[balthazariv]

Hello,

protected position. Arent you using an area protection mod ?

In testing I found that it was with the mod simple_protection.

Too bad only cobblestones are used in your mod but i like it because you have a small machine compared at [Mod] TBM Reloaded! [0.5][tbm]

Maybe you can join and make one mod with your 2 machine.

Thanks

PS : Can you refresh your post header with a valid link and screenshot

[aldobr]

The basic logic in both mods is the same. Don added a way better visual model to the machine. Honestly my skills are lacking in that area.

[balthazariv]

You already know more than me. I'm just a tester.
