Problem with a .sqf script

[VonNexus 10]

Heya,

basically I've got a guy tied up in a depot wich I called hostage1. What I want to do is displaying a hint when a player is at least at 5 meters from him. I could do it via trigger, but I've got the editor full of them so I'm trying to execute this using a basic .sqf script (those things with if, while, do, else). I've read some guides but still didn't figure out how to accomplish a basic .sqf script. This is what I tried to use

_unit=_this select 0;
_hostage1=_this select 1;


if (_unit distance _hostage1 > 5) then {hint "You found the hostage!"}; 

It seems right to me, but doesn't work. I tried to exec it in a trigger and even in the init but it just won't work. So what is wrong?

I like to use scopeName and breakOut for stuff like this. I am sure there are other ways to do it, but here's how I would write it:

_unit = _this select 0;
_hostage1 = _this select 1;


scopeName "main";
while {true} do{
if (_unit distance _hostage1 < 5) then {
hint "You found the hostage!";
breakOut "main"
};
};

Also from what you've written you want to use

[b]_unit distance _hostage1 <= 5 [/b] 

instead of

_unit distance _hostage1 > 5

_unit=_this select 0;

_hostage1=_this select 1;

if (_unit distance _hostage1 > 5) then {hint "You found the hostage!"};

Your script does't work because it have not a check

in edit the trigger is check continuous so just insert:

_unit=_this select 0;

_hostage1=_this select 1;

while {true} do{

if (_unit distance _hostage1 < 5) then {

hint "You found the hostage!";

sleep 1;

};

however it's always better to insert a pause in a check with the comand: sleep x

blue = < (lower to)

green = check loop

red = variable (waiting in seconds)

_unit = _this select 0;
_hostage1 = _this select 1;

WaitUntil {sleep 1; _unit distance _hostage1 < 5};

hint "You found the hostage!";

Better i think :)

Where do I put the exec command for the script? And has it to be a nul=[] execVM "filename" or a simple this execVM "filename"?

Better i think

right friend!

that is another method!

@VonNexus can recall the script with a trigger with in its onact: nul=[] execVM "nameofscript.sqf"

or

waypoint (the same)

or

create game logic in its init:

nul=[] execVM "nameofscript.sqf"

[giallustio 770]

Yep! But this:

while {true} do{
if (_unit distance _hostage1 < 5) then {
hint "You found the hostage!";
sleep 1;
};

it's a loop with no end :)

I actually used Giallustio's code, called the file hostagearea.sqf. Then I created a game logic and put the maxjoiner's code in the init, but when I get close to the hostage no hint is displayed.What is the problem?

[giallustio 770]

How do you call it?

Put this as your script:

_unit = _this select 0;
_hostage1 = _this select 1;


scopeName "main";
while {true} do{
if (_unit distance _hostage1 < 5) then {
hint "You found the hostage!";
breakOut "main"
};
};

then in the Act of your trigger put this: null = [rescuingUnit,hostageUnit] execVM "hostageRescue.sqf"

Of course 'rescuingUnit' and 'hostageUnit' will be the names of those units in the editor.

What do you mean?

You have to define _unit and _hostage1.

So when you launch the script you have to do something like this:

_script = [player,hostage_name] execVM "file.sqf";

_script = [player,hostage_name] execVM "file.sqf";

I actually use this code with player and hostage name (ostaggio1) and I renamed the .sqf files. It's like null = [player,ostaggio1] execVM "h1.sqf". However it still won't work.

[giallustio 770]

Ok, where do you write:

null = [player,ostaggio1] execVM "h1.sqf"

Cosi ci capiamo meglio? :)

In a trigger activated by Civilian, its area covers the place where the hostage is (of course the hostage is a civilian)

Ok, where do you write:

null = [player,ostaggio1] execVM "h1.sqf"

Cosi ci capiamo meglio? :)

[giallustio 770]

Well...Put the code in your init.sqf, it's better :)

[VonNexus 10]

Now it works! Last question: after the script of the hostage , can I write something like "Ostaggisalvati=true" so I can use "Ostaggisalvati=true" as a trigger condition?

Well...Put the code in your init.sqf, it's better :)

[giallustio 770]

Yes you can :)

Add it after:

hint "You found the hostage!";
