Whats the opposite of "isNil" ?

[alexharvey52 11]

what is the oposite for isNil in an sqf arma file?

Lets say just for my explaining purpopes the oposite of 'isNil' is 'isTrue' this is what im trying to do:

	if (isNil "acre_sys_io_pipeHandle") then
{  
	if (!isDedicated) then {titleText [ACREWARNING_MESSAGE, "PLAIN", 3];};
};

if (isTrue "acre_sys_io_pipeHandle") then
{  
	[5663, acre] call acre_api_fnc_joinChannel;
};

Thanks is advance!

!(isnil "acre_sys_io_pipeHandle") [using your example above - not sure in what context]

try that

! means Not or you can just use not instead they both work

...or you could try:

if (isNil "acre_sys_io_pipeHandle") then
{  
	if (!isDedicated) then {titleText [ACREWARNING_MESSAGE, "PLAIN", 3];};
}
       else
{  
	[5663, acre] call acre_api_fnc_joinChannel;
};

};

I tried using the else statement before you posted it and I was getting an error on the "[5663, acre] call acre_api_fnc_joinChannel;" line but when its not in there it works fine.

Also I need to do this loop throughout the time the player is on the server. Where should I put it?

Generally in programming a ! symbol means the negation of the expression that is after it.

I thought it would be better to carry on this thread instead of making a new topic.

I have something else I need help with must alike my previous questions but more advance.

while {(isServer)} do
{

if (!isNil "acre_sys_io_pipeHandle") then
{  
	[5663, acre] call acre_api_fnc_joinChannel;
	sleep 5;
};

if (isNil "acre_sys_io_pipeHandle") then
{  
	titleText [ACREWARNING_MESSAGE, "PLAIN", 3];
	sleep 5;
};

};

I want the mission to constantly check the if statements. This works with the code above however it then carrys on looping the commands, this is ofcourse expected. What I need is for it to loop forever and if the text is already on the screen then it doesnt display it again.

Ive written an example in shudo code below:

while {(isServer)} do
{

if (!isNil "acre_sys_io_pipeHandle") then
{  
		[5663, acre] call acre_api_fnc_joinChannel;
	sleep 5;
};

if (isNil "acre_sys_io_pipeHandle") then
{  
	titleText [ACREWARNING_MESSAGE, "PLAIN", 3];
	sleep 5;
               if acre warning message is already on screen then skip step
};

};

Once I have got it working on the warning message I will try and apply it to the acre join channel command.

IF U WANT HELP YOU HAVE TO EXPLAIN WHAT RE U TRYING TO ACHIVE

while {(isServer)} do
{

if (!isNil "acre_sys_io_pipeHandle") then
{  
	[5663, acre] call acre_api_fnc_joinChannel;
	sleep 5;
};

if (isNil "acre_sys_io_pipeHandle") then
{  
	titleText [ACREWARNING_MESSAGE, "PLAIN", 3];
	sleep 5;
};

};

from my point of view the idea of this code is simply wrong...

I tried using the else statement before you posted it and I was getting an error on the "[5663, acre] call acre_api_fnc_joinChannel;" line but when its not in there it works fine.

this:

if isServer then
{
 while { true } do
 {
   if (!isNil "acre_sys_io_pipeHandle") then
   {  
     [5663, acre] call acre_api_fnc_joinChannel;
   }
   else
   {  
     titleText [ACREWARNING_MESSAGE, "PLAIN", 3];
   };

   sleep 5;
 };
};

dont have to be same as this:

if isServer then
{
 while { true } do
 {
   if (isNil "acre_sys_io_pipeHandle") then
   {  
     titleText [ACREWARNING_MESSAGE, "PLAIN", 3];
   }
   else
   {  
     [5663, acre] call acre_api_fnc_joinChannel;
   };

   sleep 5;
 };
};

since u didnt explain much... i can just guess that this can be the solution...

if isServer then
{
 _null = [] spawn
 {
   waitUntil { !isNil "acre_sys_io_pipeHandle" };
   [5663, acre] call acre_api_fnc_joinChannel;
 };
};

....and another question is... if its really good idea to call, not spawn, that function...

btw... if that should be work around public variables u should probably stop and look at https://community.bistudio.com/wiki/BIS_fnc_MP
