I suggest : How to comment the code .

both way also can prevent the code from running..

This 1 we usually use when come to "Disable" multiple line

/* Part that Doesnt Run */

Just for 1 or several line usually.......

// Line that Doesnt Run

LOL i messed up with C Programming =='' ~

O.o, since when did they allow block commenting?

[iBallBar]

To be sure . I'm looking to find the way to comment in 'src/map/script.c' . I think we can use block comment.

const char* skip_space(const char* p)
{
if( p == NULL )
 return NULL;
for(;
{
 while( ISSPACE(*p) )
  ++p;
 if( *p == '/' && p[1] == '/' )
 {// line comment
  while(*p && *p!='n')
   ++p;
 }
 else if( *p == '/' && p[1] == '*' )
 {// block comment
  p += 2;
  for(;
  {
   if( *p == '0' )
 return p;//disp_error_message("script:skip_space: end of file while parsing block comment. expected "CL_BOLD"*/"CL_NORM, p);
   if( *p == '*' && p[1] == '/' )
   {// end of block comment
 p += 2;
 break;
   }
   ++p;
  }
 }
 else
  break;
}
return p;
}

[Z3R0]

Good to know actually... I did not know that was implemented...

[Judas]

block comment like this:

/*

*/

I think you could always do that with the code. And yeah I already used it many times. It's very helpful.

[Z3R0]

Guess I will create a video on commenting considering I was not aware you could block...

[Z3R0]

ya, ok I thought it was a recent addition... lol, been doing this for a while now, never knew about block commenting and no script I've ever seen used it

[goddameit]

really useful

[Mirage]

I was a generic simple scripter. This is SO helpful!!

*looks around* I control FIRE!!! o.o :3

[Z3R0]

I will do a few more tutorials tonight...

[Z3R0]

iFoxKun something wrong with your upload?

[Elven]

Cool !! With this more members will be able to learn scripting them self.

[Z3R0]

[iFoxkun]

Sorry there hasn't been much dev on this lately guys... my laptops been in shambles...I should be able to do more this weekend

[Arcenciel]

I've been out of the RO scene/Scripting scene for a very long time and these videos are really helpful as a refresher. They're really easy to understand.

I'm hoping to see this whole thing through. Keep up the good work!

Couple of suggestions:

- mes command has been updated.

To display multiple lines of message while only using a single mes; command,
use the script command in the following format:

mes "Line 1", "Line 2", "Line 3";

This will display 3 different lines while only consuming a single line in
the relevant script file.

http://sourceforge.net/apps/trac/rathena/changeset/15072/

- I feel that changing the color of the text in game inside an NPC window should be covered as an extension of some sort to Chapter 1. It's something basic.

- Terms that could be defined as I'm assuming not everyone knows it

-- String

-- Integer

- I think you should speak up more if not just increase the gain on your microphone settings. I have to set the volume of my computer to the max in order to hear you clearly. =/

I'm considering replacing the basic scripting guide in the wiki with a transcripted version of this series.

[Z3R0]

Ok, will definitely work on that, unfortunately, speaking louder is not an option, due to my 2 year old sleeping, however I will look into the increase of gain...

[Ghost]

Good work!

[Z3R0]

Sorry guys, wasn't able to get any laptop time in this weekend... I apologize... I swear I'll have some more by the end of the week though

[Emistry]

LOL...Dont mind it...take your time...^^ All we have here....is TIME !! haha ~

still a long way to go...no need to push yourself so hardly...

[Judas]

yep take your time!

[Crescendo]

Wow thank you for posting this. I have been wanting to learn more about scripting so I can be more useful Quite the comprehensive guide! ... and videos! You're awesome, Z3R0!

[Yuki]

It's great in the first place that you are dedicating some time to make and post these videos. You've been a great support for several of the members here =D!

You don't have to rush such projects. In fact, for these kinds of videos, you have to take time ;D and explain clearly to avoid any confusion.

You are doing great <3!

[gustav]

the first variable tutorial doesn't work for me. when follow the tutorial only the temporary variables settings work

[Arcenciel]

How are you doing it? I've gone through what's available so far and didn't find any problems on the way Z3R0 explained things.
