foreach

foreach standalone include (non y_iterate version). Y_Less dropped support for this version of foreach.

This version of foreach is 19 (0.4.2). This is the standalone version, so it does not require YSI. Use this version if you do not want to include YSI.

This fork based on that fork.

Features

• Actor and Vehicle iterators.
• Multiscripts supported by FOREACH_MULTISCRIPT.
• Optimized ALS hooking process (without CallLocalFunction).
• Changed iterator enable/disable defines.
• Removed npcmodes/ scripts support.
• New functions: Iter_Index

How to install

If you use foreach only in gamemode, just include foreach like this:

#include <a_samp>
#include <foreach>

If you use foreach in filterscript, just include foreach like this:

#define FILTERSCRIPT

#include <a_samp>
#include <foreach>

If you use foreach in each of your script, just include foreach like this:

#define FOREACH_MULTISCRIPT

#include <a_samp>
#include <foreach>

Settings

Directive	Iterator	Enabled by default
FOREACH_I_Player	Player	yes
FOREACH_I_Bot	Bot / NPC	yes
FOREACH_I_Character	Character	yes
FOREACH_I_Vehicle	Vehicle	yes
FOREACH_I_Actor	Actor	yes
FOREACH_I_PlayerPlayersStream	PlayerPlayersStream[playerid]	no
FOREACH_I_PlayerVehiclesStream	PlayerVehiclesStream[playerid]	no
FOREACH_I_VehiclePlayersStream	VehiclePlayersStream[vehicleid]	no
FOREACH_I_PlayerActorsStream	PlayerActorsStream[playerid]	no
FOREACH_I_ActorPlayersStream	ActorPlayersStream[actorid]	no
FOREACH_I_PlayerInVehicle	PlayerInVehicle[vehicleid]	no

How to disable any iterator:

#define FOREACH_I_Actor 0
#define FOREACH_I_Vehicle 0
#include <foreach>

How to use

Gives $100 to all connected players

foreach (new playerid : Player) {
	GivePlayerMoney(playerid, 100);
}

Sets 130 and 170 colors to all vehicles with model 400

foreach (new vehicleid : Vehicle) {
	if (GetVehicleModel(vehicleid) == 400) {
		ChangeVehicleColor(vehicleid, 130, 170);
	}
}

Remove all existed vehicles and actors

For removing vehicles or actors in foreach loop you should use Safe functions:

foreach (new vehicleid : Vehicle) {
	DestroyVehicleSafe(vehicleid);
}

foreach (new actorid : Actor) {
	DestroyActorSafe(actorid);
}

Custom iterators

Adds two iterators with players in team 1 and 2.

new
	Iterator:Team1<MAX_PLAYERS>,
	Iterator:Team2<MAX_PLAYERS>;

stock Team_SetPlayerTeam(playerid, teamid)
{
	switch (GetPlayerTeam(playerid)) {
		case 1: {
			Iter_Remove(Team1, playerid);
		}
		case 2: {
			Iter_Remove(Team2, playerid);
		}
	}

	switch (teamid) {
		case 1: {
			Iter_Add(Team1, playerid);
		}
		case 2: {
			Iter_Add(Team2, playerid);
		}
	}

	return SetPlayerTeam(playerid, teamid);
}
#if defined _ALS_SetPlayerTeam
	#undef SetPlayerTeam
#else
	#define _ALS_SetPlayerTeam
#endif

#define SetPlayerTeam Team_SetPlayerTeam

It can be used like this:

foreach (new i : Team1) {
	GivePlayerMoney(i, 1000);
}

foreach (new i : Team2) {
	SetPlayerHealth(i, 0.0);
}

This script gives $1000 to all players from team with id 1, and kills players from team with id 2.

Custom array of iterators

Adds array of iterators with players in teams:

#define MAX_TEAMS 255

new
	Iterator:Team[MAX_TEAMS]<MAX_PLAYERS>;

public OnGameModeInit()
{
	Iter_Init(Team);

	#if defined Team_OnGameModeInit
		return Team_OnGameModeInit();
	#else
		return 1;
	#endif
}
#if defined _ALS_OnGameModeInit
	#undef OnGameModeInit
#else
	#define _ALS_OnGameModeInit
#endif

#define OnGameModeInit Team_OnGameModeInit
#if defined Team_OnGameModeInit
	forward Team_OnGameModeInit();
#endif



stock Team_SetPlayerTeam(playerid, teamid)
{
	new current_team = GetPlayerTeam(playerid);
	if (current_team != NO_TEAM) {
		Iter_Remove(Team[current_team], playerid);
	}

	if (teamid != NO_TEAM) {
		Iter_Add(Team[teamid], playerid);
	}

	return SetPlayerTeam(playerid, teamid);
}
#if defined _ALS_SetPlayerTeam
	#undef SetPlayerTeam
#else
	#define _ALS_SetPlayerTeam
#endif

#define SetPlayerTeam Team_SetPlayerTeam

It can be used like this:

new scores[MAX_TEAMS];
for (new teamid; teamid < MAX_TEAMS; teamid++) {
	foreach (new playerid : Team[teamid]) {
		scores[teamid] += GetPlayerScore(playerid);
	}
}

for (new teamid; teamid < MAX_TEAMS; teamid++) {
	printf("Team %d: %d", teamid, scores[teamid]);
}

This script sums up score from each team and prints it.
