Continue in a loop/ or goto in sqf

[inofix 10]

Hello,

i'm currently struggling with the following:

I have a while loop running and i need to continue/start from beginning at some point.

Sadly i can't find any "continue" command in sqf, neither does Goto work and scopeName + breakOut/To.

Is there any way i can continue my loop (like in C/C++) or start the loop again from the beginning without reloading the script?

Could you provide a bit more on what exactly your trying to accomplish, and maybe provide the code you have currently.

Example:

while{true} do {

_result = [] call fnc_IsAtBase;
if(!_result) exitWith { };	

if(_damage > 0) then {
	vehicle player setDamage (_damage - 0.1);
	_damage = damage vehicle player;
	Continue; // Continue loop from beginning again
};

if(_fuel < 1) then {
	vehicle player setFuel (_fuel + 0.1);
	__fuel = fuel vehicle player;
	Continue; // Continue loop from beginning again
};

// And more threads for ammo, color, and custom scripts
};

As soon as an if statement's code scope is completed it continues, you don't have to do anything. But you will need to put some sort of suspension to slow the loop down or it will freeze the game (has the possibility at least).

That's not what i need.

I want after the completed if statement continues to start the loop again from the beginning, simlar to the this here: http://www.tutorialspoint.com/cplusplus/cpp_continue_statement.htm

Ok, get you now, just do this for each of your conditions:

if([] call fnc_IsAtBase && {_damage > 0}) then {...};

EDIT: Or,

while {true} do
{
if ([] call fnc_IsAtBase) then
{
	_fixStuff = [_unit] spawn
	{
		_unit = (_this select 0);

		if(_damage > 0) then 
		{
			vehicle player setDamage (_damage - 0.1);
			_damage = damage vehicle player;
		};

		if(_fuel < 1) then
		{
			vehicle player setFuel (_fuel + 0.1);
			_fuel = fuel vehicle player;
		};
	};
	waitUntil {scriptDone _fixStuff};
};
sleep 10;
};

I may be confused about what you want... but this may be it.

EDIT: _damage & _fuel need to be defined before their if statements.

EDIT: _damage & _fuel need to be defined before their if statements.

Yea I think he gave us semi-pseudo code, just to get a concept of what needs to happen with it.

[killzone_kid 1332]

To use goto you need to write your script in .sqs and execute it with "exec" command. There are plenty of alternatives of course:

num = 0;
scopeName "main";
while {true} do
{
scopeName "outerLoop";

while {true} do
{
	num = num + 1;
	hintSilent str num;

	if (num == 2) then
	{
		systemChat "WTF";
		breakTo "outerLoop";
	};
	if (num == 4) then
	{
		breakTo "main";
	};
	sleep 1;
};
sleep 1;
};
hint "Done";

scopeName, breakTo

But this is a terrible idea. There's a reason structured programming is specifically called "goto-less programming"

[Ed! 13]

what if you avoid a loop and do something like this.

[u]functionName[/u] = {
_result = [] call fnc_IsAtBase;
if(!_result) exitWith { };	

if(_damage > 0) exitWith{
	vehicle player setDamage (_damage - 0.1);
	_damage = damage vehicle player;
	[] spawn [u]functionName[/u]; //or call if you like
};

if(_fuel < 1) exitWith{
	vehicle player setFuel (_fuel + 0.1);
	__fuel = fuel vehicle player;
	[] spawn [u]functionName[/u]; //or call if you like
};

// And more threads for ammo, color, and custom scripts

};
[] spawn [u]functionName[/u];
