Return an array in stock

Hey. First of all, thank you for explaining in details why should I use cstrike/fun/engine modules instead of converting them. I really did get the point and appreceate that you dealt with my narrow-mindness till the end :D

I wanted to ask some help regarding stocks. I want to create a stock that would do the following:

Code:

stock get_team_colours( id, rgb[ 3 ] ) {
        if( cs_get_user_team( id ) == CS_TEAM_T ) {
             rgb[ 0 ] = 255;
             rgb[ 1 ] = 0;
             rgb[ 2 ] = 75;
        }
        else
//...

return rgb;
}

But this does not work. Could you please tell me how can I achieve the wanted result?

Re: Return an array in stock

The stock already does what you want it to do (trust me, try it). Remove the return rgb; line and you're good to go.

Re: Return an array in stock

The important thing to understand here is that arrays are passed by reference aka 'byref' in this language.

That means that when you manipulate an array variable inside your function, it actually changes the variable in the calling code which was provided as the argument.

Re: Return an array in stock

In amxx it is not possible to return an array or a string (basically in amxx string is an array of integers that actually can also be understood as chars).

So in this case you have just to use the function with an empty array as input. And then function will just save the rgb values directly in that array.

This will your stock look like:

PHP Code:


		
			
stock get_team_colours( id, rgb[ 3 ] ) {
        if( cs_get_user_team( id ) == CS_TEAM_T ) {
             rgb[ 0 ] = 255;
             rgb[ 1 ] = 0;
             rgb[ 2 ] = 75;
        }
}

And this way you call the function:

PHP Code:


		
			
new myRGB[3]

get_team_colours( id, myRGB )

After calling the function, myRGB array will have your desired values.

You can return a string.

Re: Return an array in stock

But returning a string is bad best is to copy it byref

That's true, it's more efficient and flexible (doesn't have to be constant size). However, it's good that OcixCrom posted because we shouldn't spread false information.

I'm pretty sure someone(Klippy? PRoSToTeM@?) posted a good explanations about that. You should try searching.
