Command block does not work

[SysoevDV 0]

Hi.
Please tell me why when I use the command block (via the adapter) for some reason it is not allowed to set its value.
Example (from Wiki):

local component = require("component") 
local cb = component.command_block 
local ticks = math.floor(1000/60/60 * os.time() - 6000) 
print(os.date()) 
cb.setValue("time set " .. (ticks + 24000)) 
cb.run() 
print(os.date())

And I get an error:

/command:8: attempt to call field 'setValue' (a nil value)
stack traceback:
/command:8: in main chunk
(..tail calls..)

So how do I get a command block to execute commands through OC?
Thank you in advance for your answers!

It's possible that this functionality was removed, since you're looking at the old wiki and I can't find anything about it on the new one, which is at:

 

http://ocdoc.cil.li

 

If you need to execute commands via computers, you could take a look at (and likely use) the debug card's component:

The command block component interaction is disabled by default in the config, you need to enable it manually. Though as far as I know it does nothing that the debug card can't do, so you could just use that instead.

Command blocks has three methods:

cb.setCommand(command)
cb.getCommand()
cb.executeCommand()

So your code must look like this:

local component = require("component") 
local cb = component.command_block 
local ticks = math.floor(1000/60/60 * os.time() - 6000) 
print(os.date()) 
cb.setCommand("time set " .. (ticks + 24000)) 
cb.executeCommand() 
print(os.date())

If command block driver was disabled in the config, this program would crash with error "no such component".

 

P. S. This wiki is outdated, use ocdoc.cil.li.
