If true type {}

[Gnurf]

I just spent a couple of hours rewriting a fully functioning script that i´ve been developing for the past few weeks. The reason i rewrote it was becouse alot of times there would be two if operators testing the same value and setting a variabel each
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">
? _metrue : _variabel1 = 1
? _metrue : _variabel2 = 2
[/QUOTE]<span id='postcolor'>
So I figured i that i could simplifie this by having only one if operator and using then {} to execute the setting of the two variabels
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">
? _metrue then
{
_variabel1 = 1
_variabel2 = 2
}
[/QUOTE]<span id='postcolor'>
Imagine the joy I felt when I discoverd that I apparently aint allowed to do that

if operator (and all other logical operators, i assume) must have their function body on the same row as the operator it self
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">
? _metrue then {_variabel1 = 1}
[/QUOTE]<span id='postcolor'>

Ok I can live with that and have the whole body of the operator on one row (they will be long and hard to debug but what you gonna do ). BUT PLEASE&#33;&#33;&#33;&#33; let there be away to add more then one event to the operators body
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Quote </td></tr><tr><td id="QUOTE">
? _metrue then {_variabel1 = 1 _variabel2 = 2}
[/QUOTE]<span id='postcolor'>

I could still use the old version of the script...but i dont want to.

You are mixing scripting commands with function call commands. In OFP functions (called with the call command) are basically strings.

So, if you want to mix &#39;em you have to be sure to do it correctly

Something like this:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
?_a&#62;_b&#58; call &#34;C=0;D=1&#34; or ?_a&#62;_b&#58; call {C=0;D=1}
[/QUOTE]<span id='postcolor'>

Note that by using that you can only write to global variables since local variables defined within the scope of "" or {} won&#39;t exist after the call command is completed&#33;

Now if you keep to only function syntax then you write it liike this:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
if&#40;_a&#62;_b&#41; then
{
_C = 0;
_D = 1;
};
[/QUOTE]<span id='postcolor'>

or shorter
if(_a>_b) then "_C = 0;_D = 1";

If you want to use script syntax only, do as bigboppa wrote

Thanks both of you

bigpoppa´s tip works excellent (just tested it on a small test script)

denoir, im sure all you wrote is true but, i cant say i understood half of it. (probably becouse im an idiot )


I anticipated that the varaibels in {} would be locals so thats no problem. But whats the diffrence between scripting commands and function call commands? Can both types be used in a script *.sqs? Im asking becouse when i run this code
i get an "invalid number in expression" error.
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
if&#40;_a&#62;_b&#41; then
{
_C = 0;
_D = 1;
};
[/QUOTE]<span id='postcolor'>

Maybe its a bit to much to ask for an explenation to all this, so if anyone could help point me in the right direction to some information it would be really apreciated.

Thanks again&#33;

Nope they can&#39;t. Functions are defined in sqf fíles. A function is actually treated as a single expressions so there a number of limitations. Script constructs @,~, ? or goto are not allowed. Semicolons are strictly required, as end of line has no special meaning and is considered as normal space character.

Example: If a < b then loop 10 times writing "Hello" to screen. a,b are input parameters.

Script: loop.sqs
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
_a = _this select 0
_b = _this select 1

_i = 0

?_a&#62;b&#58;goto &#34;end&#34;

#loop
hint &#34;Hello&#34;
_i = _i + 1
?_i&#60;11&#58; goto &#34;loop&#34;

#end

Function:
loop.sqf
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
private &#91;&#34;_a&#34;, &#34;_b&#34;, &#34;_i&#34;&#93;;

_a = _this select 0;
_b = _this select 1;

_i = 0;

if&#40;_a&#60;_b&#41; then
{
*** while &#34;_i &#60; 10&#34; do
*** {

*** *** hint &#34;hello&#34;;
*** *** _i = _i+1;
*** };
};

They are also called differently:
Script:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
&#91;a,b&#93; exec &#34;loop.sqs&#34;
[/QUOTE]<span id='postcolor'>
Function:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
&#91;a,b&#93; call loadFile &#34;loop.sqf&#34;
[/QUOTE]<span id='postcolor'>

The big advantage of functions is that they can return values:
sum.sqf:
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
private &#91;&#34;_a&#34;, &#34;_b&#34;, &#34;_c&#34;&#93;;
_a = _this select 0;
_b = _this select 1;
_c = _a + _b;
_c
[/QUOTE]<span id='postcolor'>

Gives the possibility of
</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">
_c = &#91;_a,_b&#93; call loadFile &#34;sum.sqf&#34;
[/QUOTE]<span id='postcolor'>

Which is impossible with scripts.

[Gnurf]

They can return values&#33;?&#33;
the possibilites&#33;

Thanks for all the help and information

Cant thank you enough

[FFAK]

Is this code working?

</span><table border="0" align="center" width="95%" cellpadding="3" cellspacing="1"><tr><td>Code Sample </td></tr><tr><td id="CODE">if {player1 hasweapon Binocular} then {player1 showmap true}[/QUOTE]<span id='postcolor'>

and I want to force all other players showmap false...

how does it working?
thanks
