World Anchors and computer screens

[Deimos161]

Hey guys,

I have world anchors banned for non OPs but I have some placed under some computers in my spawn to keep them running at all times. But they don't` seem to be working. IE the computers are turning off.

Also I am having trouble with two of my monitor displays.(These displays, show my banned items on my server). Now the problem that I am having is that the text is disappearing of the screens until I break a monitor and replace it.

my monitor is 5wide by 6 high.

This is my code I am using

local w,h = term.getSize()



local function printCenter(line)

  local width = string.len(line)

    if width < w then

          local x,y = term.getCursorPos()

          term.setCursorPos(w/2 - width/2,y)

    end

  print(line)

end



printCenter 'Banned Items'

printCenter ''

I'd just name the program you want to run all the time as "start" on either the local computer or a disk. Then whenever the chunk is loaded, that program will run.

It's startup isn't it? Do both start and startup work now?

[Djinnii]

no, your probably right, it's probably "startup". Didn't sleep much last night :-)

[Deimos161]

it is startup which I have done. The startup program is shell.run("monitor","top","rules") but if a chunk gets unloaded the computer has to be turned back on.

The aim of these screens are to display my banned items and rules.

[Djinnii]

if the program is named startup it will load that program everytime the chunk is loaded. I had a similar setup with my own rules/banneditems not too long ago.

[Deimos161]

well thats what I have. But computers do not automatically turn on when a chunk is loaded. You have to click the computer before it will turn on, then when the computer starts it runs what every program is in startup.

My problem is chunk loaders are not working and my monitors seems to be all kinds of mucked up.

[Djinnii]

Your doing something wrong. Sorry. But you shouldn't need to use chunk loaders with computercraft.

[Deimos161]

tell me what you do?

The code I am using is above (this is saved on my server via FTP)

• I then click the computer
  
• type: edit startup
  
• type: shell.run("monitor","top","banned")
  
• control - save
  
• control - exit
  
• type: startup so it runs
  

If I leave the chunk unloaded for a bit then return the computer has turned off.

[Djinnii]

I see.... I just put the program in "startup" rather than try and run another program from it.

I'd also tend to test it using "reboot" to save having to unload the chunk etc...

p.s. in your post I do believe your missing a );

It seems like it's something like your computer is turning on but it's being loaded before the monitor is and so when it tries to connect to the monitor it can't because it doesn't see it as being there, possibly try adding a delay at the top of the script to give the monitors chance to load before attempting to write to them..

[Deimos161]

Hmm that is a good idea, thanks.

Oh I dont know who to add a delay to it. is it just

 sleep(1) ? 

[theprolo]

Yeah, that should work. Chances are there's not anything more than a second gap between the computer and monitor being loaded.

It's because your monitor and cpu are not in the same chunk. The entire thing must be in one chunk or you will have this problem. Turn on chunks with REI (or WorldEdit CUI with //chunk) and you can check to see if indeed that is your problem.

[Deimos161]

If I am using shell.run("monitor","top","rule") that would mean my screen is on top of my computer, meaning that it is in the same chunk so that is not my problem.

No, that would just mean that your cpu is on top of your monitor. That doesn't necessarily mean it is the same chunk (Minecraft's 16x16x256 chunk).

I promise you that's your problem.

Edit: the WHOLE structure needs to be in one chunk. All the monitors and CPU.

[Deimos161]

but a chunk is 256 blocks deep, meaning if my computer is the middle of a chunk (which it is) and then my display set up is on top of that. That would mean my display and computer are in the same chunk....

[pherce]

What are you viewing chunks with?

We had the exact same problem in our spawn (which is permanently loaded with MultiVerse). Always had to open the cpu for 'startup' to work. Turns out the monitor was not completely in the chunk.

[Deimos161]

I am looking on the REI map

I have also used //chunk on the top left and the top right corners of the monitor and they are both in the same chunk.

[theprolo]

If the monitor is above the computer, then it is definitely in the same chunk(unless it extends over the chunk borders). Chunk loaders load the whole chunk, not just a portion of it.

[Deimos161]

So I fixed it by deleting the top level of monitors >.< dunno why that fixed it but they are now staying on
