Well then mine would be just:

pawn Code:

Distance = floatsqroot(floatpower(floatabs(X1 - X2), 2) + floatpower(floatabs(Y1 - Y2), 2) + floatpower(floatabs(Z1 - Z2), 2));

And YIJET's would not return the correct value if X1 was a positive and X2 was a negative... It needs the absolute value.

Eh' I've been up all night, guess I over thought it. Thanks mate.

I know, but I don't know why the function is slow, calculating the square root of something is just simple division. But isn't there an alternative of floatsqroot for more speed?

Like on this page for example:

Re: Useful Functions - RyDeR` - 28.10.2012

You're releasing functions that have been posted since ages. Something new would be more useful.

Re: Useful Functions - Emmet_ - 28.10.2012

But they're more efficient!!11

BeepComputer, beeps whatever computer the server is hosted on!

pawn Код:

stock BeepComputer()
{
    print("•");
}

LOL, I never thought that could be possibile. Printing a point means beeping the machine, tested and working

nice one, (Bad because beeping is leaving one space just like \n).

Re: Useful Functions - RyDeR` - 28.10.2012

Still can't see anything more efficient than before. Anyway you can also use '\a' to beep, just some random information.

Edit: ups, ****** was faster by 4 minutes, damn you
delete this post if its concider'd spam

Re: Useful Functions - Emmet_ - 28.10.2012

I didn't know those functions exist. I'm not going to browse through 300 pages to find out.

My vending machine function doesn't exist though. I can prove it just by one ****** search.

Ever heard of the search button?

More functions that will get me yelled at:

pawn Код:

new bool:FALSE = false;

#define INI: File:
#define INI_Open(%0)              fopen(%0, io_readwrite)
#define INI_WriteInt(%0,%1,%2)    INI_WriteString(%0, %1, #%2)
#define INI_WriteFloat(%0,%1,%2)  INI_WriteString(%0, %1, #%2)
#define INI_WriteString(%0,%1,%2) fwrite(%0, %1), fputchar(%0, '='), fwrite(%0, %2), fwrite(%0, "\r\n")
#define INI_Int(%0,%1,%2)         do{new _string[128];while(fread(%0,_string)){if(strcmp(_string,%1,false,strlen(%1))==0&&_string[strlen(%1)]=='='){strmid(_string,_string,strlen(%1)+1,strlen(_string)-2,128);%2=strval(_string);fseek(%0,0,seek_start);break;}}}while(FALSE)
#define INI_Float(%0,%1,%2)       do{new _string[128];while(fread(%0,_string)){if(strcmp(_string,%1,false,strlen(%1))==0&&_string[strlen(%1)]=='='){strmid(_string,_string,strlen(%1)+1,strlen(_string)-2,128);%2=floatstr(_string);fseek(%0,0,seek_start);break;}}}while(FALSE)
#define INI_String(%0,%1,%2,%3)   do{new _string[128];while(fread(%0,_string)){if(strcmp(_string,%1,false,strlen(%1))==0&&_string[strlen(%1)]=='='){strmid(%2,_string,strlen(%1)+1,strlen(_string)-2,%3);fseek(%0,0,seek_start);break;}}}while(FALSE)
#define INI_Close(%0)             fclose(%0)

pawn Код:

public OnFilterScriptInit()
{
    new
        INI:test,
        money,
        Float:health,
        string[24];
        
    test = INI_Open("file.txt");
    INI_WriteInt(test, "Money", 100);
    INI_WriteFloat(test, "Health", 75.0);
    INI_WriteString(test, "String", "Sup.");
    INI_Close(test);
    
    test = INI_Open("file.txt");
    INI_Int(test, "Money", money);
    INI_String(test, "String", string, 24);
    INI_Float(test, "Health", health);

    print(string);
    printf("You have $%d.", money);
    printf("%f", health);
    
    INI_Close(test);
    return 1;
}

Poor emmet.

OT: Those are some interesting macros, lol. I actually wasn't aware you could make them so long. Cool!

Wikipedia has a nice pseudo-code on the Quadtree page, it's quite well explained if you ask me.
