[1.4] SSP os.sleep not working correctly.....

I cant get this simple program to work because os.sleep command does not respond correctly


function actvBB (x) –this is to activate BlockBreakers
for i= 0 , 50 do
rs.setBundledOutput("left" , 8)
os.sleep (0.4)
rs.setBundledOutput("left" , 0)
end
end

this 0.4 sec delay takes about 20 secs
it worked just fine earlier in other save of mine with same settings.
EDIT: I asked it loop only once
And there are no other computer connected.

Well, i dont know why os.sleep() doesnt work, try using sleep(n) instead. If none works, try updating your Forge. That might help. Or maybe, update your ComputerCraft.

The sleep delay depends on the tick duration and on the number of active computers. Maybe you're having a lot of working computers besides?

How do you know how much the delay takes? By looking at the cable?
You forgot to put a sleep after setting the output to 0 (off), so it will loop back instantly and turn it on, and it will look like it never turned off.
So…
0.4 seconds x 50 iterations = cable is on 20 seconds

LOL I feel so noobish reading this and not understanding…

Basicly, Instead of stopping a little bit to turn the cable off it instantly loops back to rs.setBundledOutput("left" , 8) because there is no sleep(n). Think of it like this, The cable turns on, waits 0.4 seconds then turns off and instantly back on because of the loop. Having a sleep(0.4) would fix this. :)/>/>
Oh and… That was quite a pointless post? No offence.

so I edited the info and I stand strongly with my point.

Add a print(i) inside the loop, and you'll see that it loops 50 times.
When you see that you're wrong, add the second sleep that we said and it will work.

Let's try to make a painting to explain this,

The lines made by the pencil are instant, they are there just to show how it moves thru the loop
