Additional Script Command for Math Function: abs(x);

[JayPee]

This is just a additional script command for Math Function. Since I dont know yet on how to make a .diff file we will just do it manually.

Function: abs(<numbe);

1.) Edit src/map/script.c

2.) Find BUILDIN_FUNC(distance) then add this below

//JayPee Additional Math Function: absolute

BUILDIN_FUNC(abs)
{
int a;
int x;
x = script_getnum(st,2);
a = abs(x);
script_pushint(st,a);
return 0;
}

3.) Now find BUILDIN_DEF(set,"rv"), then add this below.

BUILDIN_DEF(abs,"i"), //JayPee

4.) Recompile your server.

And in case anyone needs it NOW before recompiling and restarting, you could use a script function:

function	script	abs	{
.@i = atoi(getarg(0));
return ( (.@i < 0) ? -.@i : .@i );
}

thanks to the r15982: Script Engine Update !
