If I launch, in different times

[Nicolas Eymerich 0]

What does happen to local variables?

This is the problem:

I've a script which allow user to choose what type of units will be created.

;---part of the script---

_Type = _this select 3 (<- arguments passed by another script)

? (_type == "Tank") : goto "Tank"

? (_type == "AA") : goto "AA"

Now:the part of the script related to Tank is equal to the part of the script related to AA.

However, there're two lines I'd like you to bring your attention:

#Tank

_object = "Type of tank" createvehicle ...

"Type of soldier" createvehicle [Position, group P_red] (<- P_red is

the name of a dead man in the editor)

"Type of soldier" createvehicle [Position, group P_red]

"Type of soldier" createvehicle [Position, group P_red]

_Commander = units (group P_red) select 1

_driver = units (group P_red) select 2

_Gunner = units (group P_red) select 3

[_commander] join GrpNull; [_driver, _gunner] join group _commander

;put in the vehicle the created units

_commander moveincommander _object

_driver moveindriver _object

_gunner moveindriver _object.

The part above of the script is equal to "AA"

Okay, now the fun () thing.

I launch twice times the script (distance ~2 second one form each other). In the first time, the script creates the AA and it is all right. The second time, the script should create the Tank.

And it does that but... the crew is not inside the tank...

Yesterday evening, pretty tired, I've tried to change those lines (only in the tank part)

_Commander = units (group P_red) select 4

_driver = units (group P_red) select 5

_Gunner = units (group P_red) select 6

insted than

_Commander = units (group P_red) select 1

_driver = units (group P_red) select 2

_Gunner = units (group P_red) select 3

And it worked....

Why???

and, of course, how Can I solve this problem and where do am I mistaken?

_Commander = units (group P_red) select 1

Any group is always global.

Group P_red unit array on first execution: [commander, driver, gunner]

On second execution: [commander, driver, gunner, 2commander, 2driver, 2gunner]

Your first try moved the first crew into the second AA tank.

This select 3 / 4 / 5 will only help once because of the right but still static selection.

Thanks for your reply Trapper

But I didn't get it.... Sorry, Could you explain in a different way, please?

Let's see...

A group is always global.

units (group P_red) returns an array of all units in group.

So P_red acts like a global array variable.

Group count P_red at first is 1, after a few seconds it's 0 because the death of the only member is recognized.

At first script execution group count becomes three. At the 2nd six, at the 3rd nine and at the 4th twelve. A group can't be bigger than twelve.

The remaining local parts of every script execution always select the first three units in the group array (global). So always the first spawnend soldiers are moved between vehicles and the later ones are ignored.

Thank you very much (again) for your interesting consideration...

However there's something I don't understand (please have patience)...

I mean: if "units group P_red" act as a(global) array and if I use the fllowing statement:

[_commander] join grpnull; [_driver, _gunner] join group _commander

The array "units group P_red" should return 0 (the original dead man because the squad is now composed by a single dead man) the first time I launch the script. And so should happen even he second time and the third time and so on...

However, your considerations explain very well the reasons the script does'nt work... So what is the mistaken I'm still doing? And How can I bypass it?

Hm, that's my fault. You're right grpNull should do it. I've overlooked the grpNull line. - Hopefully my false theory still helps to find a solution. It looks like the group changes are faulty.

I don't know if this is exactly your script as I notice some possible syntax errors:

"Type of soldier" <s>createvehicle</s> createunit [Position, group P_red]

_Commander = <s>units (group P_red) select 1</s> units P_red select 1

[_commander] join GrpNull; [_driver, _gunner] join <s>group</s> _commander

(comref is self-contradictory about that)

Try to check script lines in question with hints like this:

hint format ["Group is %1",p_red]

It's all right Don't worry...

I've compiled a new script and I've understand that the real problem wasn't in the script I've posted but in another one...

Thanks however for your help

By the way: I'm searching a 3d dialog tutorial (I've already the utility writtwen by VektorBoson). Do you know if is there anyone on the web or do you know someone who can help me?
