2021-04-18: Keywords

Most people know that YSI adds foreach to the PAWN language, but here is a list of other keywords added by it:

• foreach - Efficiently looping over sparse arrays and iterators.
  

foreach (new i : Player) printf("Player %d", i);

• task - Timer function that is always running as long as the server is up.
  

task Ping[1000]()
{
____printf("Ping");
}

• ptask - Similar to ?task?, but has a ?playerid? parameter.
  

ptask PlayerPing[1000](playerid)
{
____printf("Ping %d", playerid);
}

• loadtext - Load localised string data for displaying text.
  

loadtext core[ysi_properties];

• remote - A public function that can be called from other scripts with compile-time parameter checking.
  

remote MyFunc(a, b[])
{
}

• broadcastfunc - Call a remote function in all other scripts.
  

broadcastfunc MyFunc(42, "Hello World.");

• inline - Declare a function inside another function, and get access to the enclosing function?s variables.
  

stock Outer(a)
{
____inline Inner(b)
____{
________printf("%d %d", a, b);
____}
}

• using - Pass an inline function to another function as a callback.
  

INI_Parse(file, using inline Local_Parse);

• hook - Use a callback multiple times in multiple files without conflict.
  

hook OnPlayerConnect(playerid)
{
}

• global - When running multiple scripts, only one should be in charge of, say, the anti-cheat. This declares a function as ?global?, such that all scripts can use it but only one script will be in charge.
  

global AC_GiveWeapon(playerid, weaponid, ammo)
{
}

remote functions are called in ALL other scripts, global functions are called in just one.

• foreign - Goes with global to inform a script that this function is in a different script.
  

foreign AC_GiveWeapon(playerid, weaponid, ammo);
