I used execVM in the init to call this script, it's used to indetify the players and execute different scripts for each player.

_playerArray = ["p1", "p2", "p3", "p4", "dummy1"];
_playerCounter = 0;
while {(_playerCounter  +1) < (count _playerArray)} do {
if ((_playerArray select _playerCounter) == player) then {
//		if(_playerCounter == 0) then {
//			execVM "Scripts\Player\p1 start.sqf";
//		};
	if(_playerCounter == 1) then {
		execVM "Scripts\Player\p2 start.sqf";
	};
	if(_playerCounter == 2) then {
		execVM "Scripts\Player\p3 start.sqf";
	};
	if(_playerCounter == 3) then {
		execVM "Scripts\Player\p4 start.sqf";
	};
	if(_playerCounter == 4) then {
		execVM "Scripts\Player\p1 start.sqf";
	};
};
_playerCounter = _playerCounter +1;
};

The problem I get this errror...

Error in expression <f ((_playerArray select _playerCounter) == player) then {
hint "Is Player";
i>
 Error position: <== player) then {
hint "Is Player";
i>
 Error Generic error in expression

Absolutly now clue whats wrong... sorry if it's just a dump careless mistake.

Thank you for the help :)

Try

_playerArray = [p1, p2, p3, p4, dummy1];

They can't be strings.

I figured the problem out, yes you were right, and it needed to be if ( vehicle .... == player).

But now I got a new problem I want to use this script to check if a player joined or if an script is needed to handle this unit.

I use it in the init.sqf with the statement if(!isServer) exeitWith{}; but it don't works my debug just tells me "reached main" but it doesn't seems to reach the while loop.

May you have an idea what's going wrong?

_playerArray = [dummy1, p2, p3, p4];
_playerCounter = 0;
//Variables to check if this unit is a player or not and which player
_sec_player = 0;
_third_player = 0;
_fourth_player = 0;
_p1isP = 0;
_p2isP = 0;
_p3isP = 0;
_p4isP = 0;
//stands for newcomer this counter counts until 300 after that 2 units will die
_nc = 0;
hint "reached main";
scopeName "main";
while {(_playerCounter  +1) < (count _playerArray)} do {
hint "reached while";
//checks if the unit is a player
if(vehicle (_playerArray select _playerCounter) == player) then {
	//checks which unit is detected and starts his script
	if(_playerCounter == 0 && _p1isP == 0) then {
		hint "Player 1 found";
		execVM "Scripts\Player\p1 start.sqf";
		_p1isP = 1;
		//jumps to the end
		breakTo "end";
	};

	if(_playerCounter == 1 && _p1isP == 0) then {
		execVM "Scripts\Player\p2 start.sqf";
		_p2isP = 1;

		if (_p2isP == 0) then {
			if(_sec_player < 1) then {_sec_player = 1; _p2isP = 1; breakTo "end";};
			if(_third_player < 1) then {_third_player = 1; _p2isP = 1; breakTo "end";};
			if(_fourth_player < 1) then {_fourth_player = 1; _p2isP = 1; breakTo "end";};
		};
	};

	if(_playerCounter == 2 && _p1isP == 0) then {
		execVM "Scripts\Player\p3 start.sqf";
		_p3isP = 1;

		if (_p3isP == 0) then {

			if(_fourth_player < 1) then {_fourth_player = 2; _p3isP = 1; breakTo "end";};
		};
	};

	if(_playerCounter == 3 && _p1isP == 0) then {

			if(_fourth_player < 1) then {_fourth_player = 3; _p4isP = 1; breakTo "end";};
	};
};
else {
	//if the unit isn't a player an AI script will be started
	if(_playerCounter == 1 && _sec_player != 1 && _third_player != 1 && _fourth_player != 1) then {
		execVM "Scripts\Player\AI2 init.sqf";
		_p2isP = 0;
		breakTo "end";
	};
	if(_playerCounter == 2 && _sec_player != 2 && _third_player != 2 && _fourth_player != 2) then {
		execVM "Scripts\Player\AI3 init.sqf";
		_p3isP = 0;
		if(_nc > 300) {};//KILL AI SCRIPT

		breakTo "end";
	};
};
//if anything had been detected the script will jump to this point and repeat to check the next unit
scopeName "end";
_playerCounter = _playerCounter +1;

};
//5 min after the game started unit 3 & 4 will be available to be played by an player after that they get killed
while{_nc <= 300} do {
_nc = _nc +1;
sleep 1;
_playerCounter = 0;
breakTo "main";
};
//simply restarts the script and checks all units again
while {true} do {

_playerCounter = 0;
breakTo "main";
};

I found that too, but there is a problem with the "if(_nc > 300) {};//KILL AI SCRIPT" it says ; is missing.

There is still another problem too, if the players 2,3,4 arent used (I tried this out in sp (preview)) the script will never go into the "else"-part of the statement in line 16.

I set these units as playable but it doesnt seems to matter if theyre playable or not...

_playerArray = [dummy1, p2, p3, p4];
_playerCounter = 0;
//Variables to check if this unit is a player or not and which player
_sec_player = 0;
_third_player = 0;
_fourth_player = 0;
_p1isP = 0;
_p2isP = 0;
_p3isP = 0;
_p4isP = 0;
//stands for newcomer this counter counts until 300 after that 2 units will die
_nc = 0;
scopeName "main";
while {(_playerCounter  +1) < (count _playerArray)} do {
//checks if the unit is a player
if(vehicle (_playerArray select _playerCounter) == player) then {    //<---- LINE 16
	//checks which unit is detected and starts his script
	if(_playerCounter == 0 && _p1isP == 0) then {
		execVM "Scripts\Player\p1 start.sqf";
		_p1isP = 1;
		//jumps to the end
		breakTo "end";
	};

	if(_playerCounter == 1 && _p2isP == 0) then {
		execVM "Scripts\Player\p2 start.sqf";
		hint "Player 2 found";

		if (_p2isP == 0) then {
			if(_sec_player < 1) then {_sec_player = 1; _p2isP = 1; breakTo "end";};
			if(_third_player < 1) then {_third_player = 1; _p2isP = 1; breakTo "end";};
			if(_fourth_player < 1) then {_fourth_player = 1; _p2isP = 1; breakTo "end";};
			_p2isP = 1;
		};
	};

	if(_playerCounter == 2 && _p3isP == 0) then {

Sry I'm not so familiar with that linguistic scripting languages, sorry for that but I just posted the real problem...

Can't say I understand the script but if the player is anyone of dummy1, p2, p3, p4 the else can't fire.

That's how it read to me.

Why? I ask if the one who is getting checked is == player if not shouldn't it jump over to else?

I think the problem is your using breakto as a goto and I don't think it works that way.

scopeName "end";

_playerCounter = _playerCounter +1;

Hint "this isn't working";

If you add the hint after the scope it never fires, basically the code just seems to freeze.

Maybe switch/case may be better.

Yes switch/case would be better, but it wouldn't fit the scope problem, would it?

I tried this, but it don't works:

scopeName "main";
while {(_playerCounter  +1) < (count _playerArray)} do {
//checks if the unit is a player
if(vehicle (_playerArray select _playerCounter) == player) then {
	//checks which unit is detected and starts his script
	while{_playerCounter == 0 && _p1isP == 0} do {
		execVM "Scripts\Player\p1 start.sqf";
		_p1isP = 1;
		//jumps to the end
		_playerCounter = _playerCounter +1;
		breakTo "main";
	};

	...
}
else {
	hint "else";
	//if the unit isn't a player an AI script will be started
	while{_playerCounter == 1 && _sec_player != 1 && _third_player != 1 && _fourth_player != 1} do {
		execVM "Scripts\Player\AI2 init.sqf";
		_p2isP = 0;
		_playerCounter = _playerCounter +1;
		breakTo "main";
	};
	while{_playerCounter == 2 && _sec_player != 2 && _third_player != 2 && _fourth_player != 2} do {
		execVM "Scripts\Player\AI3 init.sqf";
		_p3isP = 0;
//			if(_nc > 300) then {hint "Killed 3"};//KILL AI SCRIPT

		hint "AI 3 found";

		_playerCounter = _playerCounter +1;
		breakTo "main";
	};
	while{_playerCounter == 3 && _sec_player != 3 && _third_player != 3 && _fourth_player != 3} do {
		execVM "Scripts\Player\AI4 init.sqf";
		_p4isP = 0;
//			if(_nc > 300) then {hint "Killed 4"};//KILL AI SCRIPT

		hint "AI 4 found";

		_playerCounter = _playerCounter +1;
		breakTo "main";
	};
};
};
