[STK] CvarToColor
 

.: Description :.

I saw many plugins where coders getting colors from cvar, but some coders dont know how to do that, so i dedicated to make this simple stock :)

.: Usage :.

PHP Code:

---

    new szColorCvar[ 10 ], iColor[ 3 ];
    get_pcvar_string( g_Cvar_mycolors, szColorCvar, charsmax( szColorCvar ) );
    
    CvarToColor( szColorCvar, iColor );

    /*******
     *  Output:
     *     
     *     iColor[ 0 ] - RED
     *     iColor[ 1 ] - GREEN
     *     iColor[ 2 ] - BLUE
     *******/ 


---

.: Example :.

PHP Code:

---

Cvar        | Stock
255103204   | 255, 103, 204
255 0 100   | 255, 0, 100
000 020 255 | 0, 20, 255 


---

.: Stock :.

PHP Code:

Nice xpaw. +karma

Re: CvarToColor( )
 

Awesome Work xPaw
I need this so much!
+karma :D

Re: CvarToColor( )
 

I would stick with jim_yang method as it calls less natives than the spaced one.
Also, you could save clamp native call.

Here a way using 1 native instead of 4 in your example (haven't cound get_pcvar since your code doesn't integrate it.
Then you use it easily :

Re: CvarToColor( )
 

Connor is right what jim's way is calls less natives, but with spaces its more friendly for server owners ;)

Re: CvarToColor( )
 

Credit is for jim_yang not Connor. Also what is the advantage to use 0xFF instead of 255 ? 255 is more readable and 'understable'.

Re: CvarToColor( )
 

I have never taken any credit for this, copied it from grenade trail plugin.


Your point.

Re: CvarToColor( )
 

I was not talking to you but xPawn so to correct it in its code above.

It doesn't anwser to the question to know the advantage of the hex notation instead of classic but well known integer. ( more friendly for a tuto )

Re: CvarToColor( )
 

clamp byte was from me, but everyone could have made it :P

Re: CvarToColor( )
 

I think that I would make it more like the get_(p)cvar_* commands (for continuity :)).
