Some questions about the Arma 2 scripting engine.

[NeoArmageddon]

I would use .sqf with

for [{_i=0},{_i<=9},{_i=_i+1}] do {

player globalChat format["%1",_i];

};

With this method _i mussnt be initialized with private.

[DiRaven]

u mean I should write something like

private "_i";
for "_i" from 0 to 9 do
{
    player globalChat format["%1",_i];
};

?
That does not work aswell.

With the following:

for [{_i=0},{_i<=9},{_i=_i+1}] do {

player globalChat format["%1",_i];

};

Getting the same:

BLUFOR Player: "ANY"

Looks like foreach loop can have multiline code block only in "spawn"ed functions.

For example:

{player globalChat format["%1", _x];player globalChat format["%1", _x];} forEach _arr;

Works perfectily in init.sqf and gives perfect result.

And

{
player globalChat format["%1", _x];
player globalChat format["%1", _x];
} forEach _arr;

Does not, causing player to say just "ANY", but still works OK in the spawned function.

Is it bug or feature?

Could it be that you're no longer supposed to do loops like this from within a timing 'critical' script like init.sqf? I don't know really, it just sounds like some new limitation. Did you try starting such as script from a trigger or something?

Will try, but later. Now want to give people to test my pra-alpha version. =)

In the meantime I have another question:
How to set unit desctiption (see Editor, unit mode, unit creating/editing dialog) via script?

[CarlGustaffa]

I have no idea. In Arma1 there was no point in doing it, as you couldn't script new or changed slots (afaik). All slots had to be preplaced in the editor, where you also set your descriptions.

Can you now make dynamic slots?

You could try the 3D Editor approach, as it generates a mission.sqf. Check what commands it uses to create playable characters, and if description can be set.

[DiRaven]

As I have tried - absolutely clearly it is possible to _remove_ playable slots without players. Later will try to add some.
Still think it is now possible to add new game slots while game is already running.

Nice tip about the editor. It's still buggy and useless but there is a chance to get an answer to my question.

One more thing... I have noticed that many loop-like commands (if, forEach and so on) works only in one-row-variant in the init.sqf script.

Like:
WRONG

{
  player globalChat format["%1", _x];
  hint format["%1", _x];
} forEach _markers;

RIGHT

{player globalChat format["%1", _x]; hint format["%1", _x];} forEach _markers;

May be this will help me when I will get back to thet piece of code... Still not sure if it is bug or feature?

And once more - quick tip. How to execute script on every machine during the MP play? Not at the start via the init.sqf but in progress.

Should it be 0:0 trigger, working for everyone? Or there is another way to do it?

This is definately not a feature and I doubt it's broken, because that would mean pretty much none of the scripts in the game would work. The old SQS was line-based, but SQF is not. If you have a case where this is not true, please present it to us

[DiRaven]

I'm using SQF ewerywhere now.

Right now have checked next code:

Works fine:

for [{_x=0},{_x<=49},{_x=_x+1}] do {arr_mkr_OPFOR_possibleDeploymentLocations = arr_mkr_OPFOR_possibleDeploymentLocations + ['mkr_OPFOR_possibledeployment_' + format ["%1", _x]];}

Gives "any" value instead of _x:

for [{_x=0},{_x<=49},{_x=_x+1}] do {
  arr_mkr_OPFOR_possibleDeploymentLocations = arr_mkr_OPFOR_possibleDeploymentLocations + ['mkr_OPFOR_possibledeployment_' + format ["%1", _x]];
}

File format - UTF8
Editor - NotePad++ with the ArmaEdit addon

BTW multiline (/* comment */) comments do not work aswell.

[DiRaven]

Due to locality I've got another question:
1. How to execute script on the server. So I must be sure that:
- It is executed.
- It is executed by server.
2. How to do the same for the certain group of players. For example for one side, for one group, for all players. And again I must be sure that:
- Script is executed.
- Script is executed by the certain group of players.

The second to my mind can be done using repeating triggers with 0:0 area. But I have no idea how to do first one.

[Worldeater]

Your examples won't work since both are missing a semicolon after the code block.

You might want to take a look at your RPT file. I guess you'll find a lot of answers in there...

Edit: Are you sure you use execVM and not exec to run your scripts?
