script to check multiple if-then conditions

[zilfondel 11]

Hi, I've spent the past few days researching and trying to build some code to check whether a unit has fired its weapon near certain marker locations (AO1, AO2, AO3). My goal is to create a script that sets the units setcaptive to true/false depending on whether it has blown its cover at that location or not by firing its weapon. In order to achieve my goal, I need to check several conditions on my unit.

Is it not possible to use this type of statement?

if ((a = 1) && (b = 1)) then {
} else {
};

This is the entire script that is blowing up on me:

if (!isServer) exitwith {};
_unit = this select 0;

_AO1 = markerpos "AO1";
_AO2 = markerpos "AO2";
_AO3 = markerpos "AO3";

while {true} do {

if ((_unit distance _AO1 < 10) && (badger1firedAO1 == true)) then {
hint "You have been a bad boy in AO1";
_unit setcaptive false;

} else {

if ((_unit distance _AO2 < 10) && (badger1firedAO2 == true)) then {
hint "You have been a bad boy in AO2";
_unit setcaptive false;

} else {

if ((_unit distance _AO3 < 10) && (badger1firedAO3 == true)) then {
hint "You have been a bad boy in AO3";
_unit setcaptive false;

} else {

hint "You are safe";
_unit setcaptive true;

};};};
sleep 1;
};

Unfortunately, this throws an error when I start the mission - Error ==: Type Bool, expected Number, String, Object, Side, Group, Text, Config entry, Displaly (dialog), Control, Team member, Task, Location

blah blah blah

line 10

This is line 10:

if ((_unit distance _AO1 < 10) && (badger1firedAO1 == true)) then {

The script worked fine until I added the second condition: && (badger1firedAO1 == true).

Any ideas how to fix this so that it works correctly?

if ((_unit distance _AO1 < 10) && badger1firedAO1) then {
};

an if statement automatically checks for boolean, so comparing it to a boolean isn't possible.

Also in your first line you forgot ==, so a == 1, not a = 1.

Thanks for the help, but now I'm getting a different error:

...e] do {

Error &&: Type number, expected Bool,code

File C....

Profiles\...

line 10

if ((_unit distance _AO1 < 10) |#|&& badger1firedAO1) then {

...which doesn't make any sense to me, as according to the Biki, my original syntax was correct:

Looks like a typo.

Check if you don't have while {true] do {

laying around.

How is badger1firedAO1 defined?

make sure it is defined as false

badger1firedAO1 = false;

A problem could be this:

if (!isServer) exitwith {};

You kick local clients out of the script, but you try to show "hint"-messages on the local clients within the same script... it couldn`t work i guess... or am i wrong?

:confused:

Well outgoing from his error (&& number expected bool) I'd think he initialized the variable with var = 0; and not var = false;

But as you mentioned this script can't be executed server-side only and the line should be removed.

Thanks for the help guys, it works perfectly.

I am now working on another script runs for a unit and checks to see if he has fired his weapon when he is near a marker.

Very simple script, but I can't get it to work.

Here it is:

_unit = badger1;

_AO1 = markerpos "AO1";
_AO2 = markerpos "AO2";
_AO3 = markerpos "AO3";

while {true} do {

if (badger1 distance _AO1 < 10) then {
_unit addeventhandler [“firedâ€, "badger1firedAO1 = true;"];
} else {

};
sleep 1;
};

Error message:

error invalid number in expression

---------------------

The previous script I tested successfully was this by itself:

badger1 addeventHandler ["fired", "badger1firedAO1 = true;"];

These scripts are basically identical except for the if-then. How do I get this to work properly? Do I need to add the eventhandler and THEN check to see if he is near the marker's location?

[cuel 25]

You don't need to loop that. That's the whole point of eventHandlers :)

eventHandler code should be wrapped in braces {}, not quotation marks.

You're also using the wrong type of quotation marks. Notice the difference between “fired†and "fired". The first ones don't work.

Else in an if-statement is also not required.

badger1 addeventhandler ["fired", 
{
if (badger1 distance (markerpos "AO1") <= 10) then 
{
	badger1firedAO1 = true;
};
}];

[zilfondel 11]

That worked, thanks - now I understand how eventhandlers work!

I'm trying to execute a script on a headless client if one is present. If not, the script should run on the server. What i tried to do is:

 

_hc = false; 
if (count entities "HeadlessClient_F" > 0) then { _hc = true} else {_hc = false}; 

if (_hc == true AND !(hasInterface OR isServer)) exitWith {hint "You're not an HC"}; 
if (!isServer) exitWith {hint "You are no HC and no Server"}; 

hint "You are an HC or the Server, script will be executed";

 

What am I doing wrong?

//run from init.sqf:

if ( (_hc && !(hasInterface || isServer)) || (!_hc && isServer) ) then {
	//this code will be executed on HC if present or on server if not.
};

Thank you very much, that was what I was looking for
