Fill clocks were introduced in the 1.8 snapshots, and were used a lot since then.
But their full potential has yet not be used, which is, why I made this blog.



WHAT IS A "FILL CLOCK"?

undefined
A fill clock is a revolutionary redstone device.
It is a clock (circuit that activates itself again and again) with the maximum speed of 20 ticks/second, which makes it the fastest clock ever.
It isn't even really resource intensive at all, even though it runs extremely fast.
It gives you many possibilities, cause of its incredible speed aswell, which you'll see in this blog.
The clock is named after the command, it is using.
It places redstone blocks and replaces them in the same tick, which activates the clock again in the next tick.

Commands:
Lower command block: /fill ~0 ~+1 ~0 ~+10 ~+1 ~0 stone
Upper command block: /fill ~0 ~-1 ~0 ~+10 ~-1 ~0 redstone_block



TIMING PROCESSES WITH "FILL CLOCKS"
undefined
Even though a clock runs at the maximum possible speed, it still triggers some command blocks earlier.
A fill command always generates the blocks with the most "negative position" first.
That means, that the block at 0 0 0 will get triggered earlier than the block at 10 0 0 
You can use this to send people messages in just one tick, but still with a custom order.
In the following example I created 10 command blocks, that are constantly running the command "/say 1", "/say 2", "/say 3", etc.
As you can see, the command blocks tell you the right commands in the correct order.

Commands:
/say 1
/say 2
/say 3
...



CHANGING THE DESIGN OF YOUR "FILL CLOCK"
undefined
Are you bored of having a "normal" fill clock?
Do you want to have a cool fill clock, which has pink wool instead of redstone blocks?
Or do you want to let the redstone blocks disappear?
That's possible with just one command block!
All you have to do is adding one command block at the "most positive" position of the clock.
Don't worry, the clock won't stop working, even if you tell the command block to replace the redstone with air.
That would only make the redstone blocks invisible, which creates a nice effect aswell.

Commands:
/fill ~0 ~+1 ~0 ~-10 ~+1 ~0 wool 2



THE "REPLACE CLOCK"
undefined
The "replace clock" allows you to turn particular blocks into clock parts in a certain area, without affecting any other blocks, that aren't supposed to be a part of the clock.
That's possible, because the fill clock now replaces certain blocks with redstone blocks.
You can use that for complicated redstone devices, in which you can't just have a stick-"fill clock".

When combining this system with the second trick, you could make a clock that turns pink wool in the area into parts of the redstone clock, so you have the possibility of making remote redstone with this tool aswell.

Commands:
Lower command block: /fill ~0 ~+1 ~0 ~+15 ~+16 ~+15 stone 0 replace redstone_block 0
Upper command blocK: /fill ~0 ~-1 ~0 ~+15 ~+14 ~+15 redstone_block 0 replace stone 0

Fixed the problem i was haviing so i have edited the comment.


EDIT: i found that unless you do this below you will find that the clock doesnt work and results in a stone column rather than a redstone repeating column.


So that you get a "fill clock" effect you need to make sure that you place the redstone command block (that is the one filling with redstone_block)


- East most.. (if you want the redstone to extend North or south)

or

- South most (if you want the redstone to extend either East or West)

or as seen above

- On top (and i am unsure wether or not this matters per direction, i can confirm it works for East and West)
if it doesnt work for North or South than switch it around (that is, redstone fill command on bottom etc..)

the opposites do not work as of 1.8.8(that is, not following these rules will result in the clock failing..

Is there an easy way change the block type if the replace clock? If there is an easy way you should add it to the tutorial :-)

Just add another command to the fill clock with the replace commands that replaces the blocks in the area with some other material.
Make sure that this command block is being triggered last.
Then make the command that replaces the redstone blocks with stone replace your new material.

Thankyou for the idea of using the replace, I will be using it to do large numbers of command blocks :)
