[QUESTION] Turtle glitching mid-program.

Title: [QUESTION] Turtle glitching mid-program.

I wrote my first bit of LUA for CC, I have some experience with C++ so it wasn't too rough but I seem to be having a weird run-time error that I can't seem to nail down, so hopefully someone here can help me. So the program digs what I believe is an efficient mining tunnel. It digs a main hallway of 3 high by 2 wide, with branches going out every 3rd row. Now it digs the first bit of hallway and first 2 branches fine but when it starts the 3rd branch it freaks. It spins around then digs up for some reason, I'm not sure why because its basically just looping what it's already done. it looks like it digs up once, then instead of digging down, it turns around twice, thinking its dug both branches, then starts the next hall.

Below is my code, thanks for the help in advance guys.

Hi Lightor,

At the moment im at work so i can not test the Code. And for me its a little bit to confusing to read your Code while Work.
I will check it when im home and see if i can help you with this.

If i understand you right than you want to start the program like this "branchmining 30 10" and then it starts digging out a tunnel 30 Long 2 wide 3 high and every 3rd row dig a branch same size is this correct?

if this is what you want to do i would try sth like this (not tested and written at work but i think you will get the point)

sorry code tags did not work ;)/>

Hey Lordlkool,

The program would indeed start like branchmind 10 5.

This would cause it to mine a tunnel that is 2 wide, and 3 tall, going 10 blocks deep into the mountainside. Then using the 5, it would make a branch every 3 blocks that is 5 deep, 3 high and 1 wide.
I feel like a picture might better help, so here is a small section of what I'm going for.












P.S. - Great point you made about the gravel and sand falling, I'll work that check in.

Hi Lightor,

nearly forgot you :D/>/>
i tested my code and fixed some errors and put in your need for the lenght of the branches.
then i added a 3rd argument for looping. means when you type like branch 8 3 2 (stardart setup when you not put in arguments)
he will dig down 5 then a tunnel 8 long and after every 4th step he will dig a branch that is 3 long 2 wide 3 high.
the reason why use 2 wide branch is that you have to move back the way so or so why not use the way to show one more row. pattern keeps the same 2 walls between each branch.
and he will do this 2 times so 10 deep.

When he is finished he will go back up 1 above the starting point.

Im not a pro but i hope it does what you need :)/>/>

EDIT: added option to place ladders so you can get down to the branches more easy and fixed the fuelcheck script put 1 in as 4th argument to use ladder else leave blank for no ladders.

Thanks for all the work you put into this! I see you put a few extra things in there, I'll have to test it and see how it goes.

Any idea what caused my original code not to work? I'm assuming you ran it and saw the issue it was having.

No Problem i like to code and a branch mining script is always good to have :)/>
Im sorry but i did not test your Code yesterday started with the Code snipped i posted when i was at work.

But when im back home today i will check up your Code and see if i can find the error :)/> (i hate it too when i dont know why stuff is not working :D/>)
for now i can not see why its glitching looks correct to me

Ok thanks, yah I just want to understand the runtime error I'm getting to better avoid it in the future.
