Mini-tutorial about Do nothing

[SFilip]

I saw alot of people using this where they don't need to so i decided to make a mini-tutorial and explain its proper use.

What Do nothing does?
It simply calls a BJ function that...does nothing.
Take a look yourself:

function Donothing takes nothing returns nothing
endfunction

I think you can figure this out even without knowing JASS

If it does nothing, why the hell blizzard made it?
In ROC it was very usefull. In it you don't have, for example If / Then / Else, Multiple Functions. Lets say you are using ROC editor and you need to make one If / Then / Else without the Else part. Try it out and you'll see you can't click on OK until you fill the red Action field. So here you must put Do nothing.

What's the inproper use?
Since you have If / Then / Else, Multiple Functions in TFT, you dont need Do nothing anymore. Yet alot of people still do something like this:

If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        <some conditions>
    Then - Actions
        <some actions>
    Else - Actions
        Do nothing

This is a complete waste...you are making your map call a bj function just to do nothing. And it would've worked if you simply used

If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        <some conditions>
    Then - Actions
        <some actions>
    Else - Actions

In other words: if you have TFT you don't even need it!

I know most of you will probably say that this tutorial is a bit useless, but oh well...things like this should be explained somewhere

Your messed up. I never knew you could write so much about this!


Heres my tutorial:

It does nothing.

Except for If/Then/Else, if you don't need the Else.

Nothing at all.

I, Zero R., hereby nominate thee, SFilip, as the only person who hath created the mostest Long Winded Tutorial ever.

PS: Halo_King, you come in second. Here's my tutorial:

Do Nothing: Self-explainatory.

Nothing at all.

But still, we have repeated this for ages. But people still uses it...
Hopefully SFilips tutorial can change that ^^

GJ!

"Do nothing" can be used in single-line "if then else"s, since both the "then" and the "else" part must have something to do... even nothing, if needed.
Regardless of RoC or TFT...

In TFT's multi-line "if"s (if then else - Multiple actions),
both the "then" and the "else" may be empty.
Putting "Do nothing" there is basically just time lost for better things...

personally, even if it's not required, i put do nothing in all open spaces i'm not suing, becuase in my mind, it makes the trigger look more complete...unless this causes a conflict elsewhere, i will probably continue to do so

this is exactly the point of this topic lol
its like an empty line that slows down your map a bit (considering the fact its not a native function)...
