.sqf scripting problem!

[Nemesis6]

Here's the script, or whatever you call it -

private
[
   "_soldier",
   "_ammo",
   "_shot",
   "_pos"
];
_soldier = _this select 0;
_ammo = "bullet7_6";
_shot = nearestObject [_soldier,_ammo];
_pos = getPos _shot;
_x = _pos select 0;
_y = _pos select 1;
_z = _pos select 2;
_maxPuffs = 2;
_i = 0;

if (_ammo != "bullet7_6") then {((_this select 0)) exec ""shockdust.sqs""; exit};

while {_i < _maxPuffs} do



{
drop ["cl_basic","","Billboard",1,8,[0,0,0],[(velocity _soldier select 0) / 2 + random 0.7 - random 0.7,(velocity _soldier select 1) / 2 + random 0.7 - random 0.7,0 + random 0.5],0,1,0.8,random 0.1,[0,3,4,5],[[0.85,0.85,0.85,0.05 + random 0.05],[0.85,0.85,0.85,0]],[0,1,0,1],0,0,"","",_shot];
_i = _i + 1
}

Now, I think it's pretty obvious what I'm trying to do, but in case it's not, it's a script/function for tank MGs. So, if the thing fired isn't an MG bullet, it needs to execute shockdust.sqs and quit.

Any help appriciated. Note that this is the latest attempt, so I may have overdone the shockdust thing.

Not that I'll be able to help .... but what's going wrong?   Any error messages?   Or is there just nothing happening at all?      

[Nemesis6]

Well, here's the thing - I can't get it to do what I want if the Ammo isn't equal to "bullet12_7", however, if it is equal to that, I can make it do whatever I want... it's like, if == is replaced by != , the line is simply bypassed.

[macguba]

12_7 or 7_6?    You have one inthe function and one in the post.

[h-]

Code: [Select]

{((_this select 0)) exec ""shockdust.sqs"";exit}This is what troubles me...
Should be

Code: [Select]

{(_this select 0) exec "shockdust.sqs";exit}But, doing this part right does not work either as exit does not work in .sqf...
So, what ever you do the function always runs through from top to bottom...

And this is probably why you have troubles....

Try something like

Code: [Select]

if (_ammo != "bullet7_6")
 then
    {
     _soldier exec "shockdust.sqs";
    }
   else
      {
   while {_i < _maxPuffs}
     do
      {
       drop ["cl_basic","","Billboard",1,8,[0,0,0],[(velocity _soldier select 0) / 2 + random 0.7 - random 0.7,(velocity _soldier select 1) / 2 + random 0.7 - random 0.7,0 + random 0.5],0,1,0.8,random 0.1,[0,3,4,5],[0.85,0.85,0.85,0.05 + random 0.05],[0.85,0.85,0.85,0],[0,1,0,1],0,0,"","",_shot];
       _i = _i + 1;
      };
   };Remember that the forums software here automatically 'lines' up the code so the drop stuff is a bit screwed...

Syntax has no guarantees...

Oh, and when doing .sqf ALWAYS penta-check that the end-of-line ( which is the ; ) is after each separate sentence...
And closing brackets must always also have ; ...

[Nemesis6]

Well, it did sound more reasonable... but it didn't work.

[h-]

How?
Describe what happens/does not/should happen... To the t...

EDIT: Here's a picture of the error, copy and paste the link into your browser.

PS. It should look like this -

private
[
   "_soldier",
   "_ammo",
   "_shot",
   "_pos"
];
_soldier = _this select 0;
_ammo = "bullet7_6";
_shot = nearestObject [_soldier,_ammo];
_pos = getPos _shot;
_x = _pos select 0;
_y = _pos select 1;
_z = _pos select 2;
_maxPuffs = 2;
_i = 0;

if (_ammo != "bullet7_6")
then
    {
    _soldier exec "shockdust.sqs";
    }
  else
      {
   while {_i < _maxPuffs}
     do
     {
       drop ["cl_basic","","Billboard",1,8,[0,0,0],[(velocity _soldier select 0) / 2 + random 0.7 - random 0.7,(velocity _soldier select 1) / 2 + random 0.7 - random 0.7,0 + random 0.5],0,1,0.8,random 0.1,[0,3,4,5],[0.85,0.85,0.85,0.05 + random 0.05],[0.85,0.85,0.85,0],[0,1,0,1],0,0,"","",_shot];
       _i = _i + 1;
     };

[h-]

Here's a picture of the error

Typical...
That's most likely the 'Generic error in expression'....

I always have these same problems when using if/then/else...

It seems that the else part does not like if there's too much stuff in there, so try turning the whole thing around:

Code: [Select]

if (_ammo == "bullet7_6")
then
    {
  while {_i < _maxPuffs}
    do
    {
      drop ["cl_basic","","Billboard",1,8,[0,0,0],[(velocity _soldier select 0) / 2 + random 0.7 - random 0.7,(velocity _soldier select 1) / 2 + random 0.7 - random 0.7,0 + random 0.5],0,1,0.8,random 0.1,[0,3,4,5],[0.85,0.85,0.85,0.05 + random 0.05],[0.85,0.85,0.85,0],[0,1,0,1],0,0,"","",_shot];
      _i = _i + 1;
    }
  else
      {
    _soldier exec "shockdust.sqs";
    };

[Nemesis6]

Still doesn't work... :-/


I suddenly feel an inexplicable urge to say "Engine limitations!"...

EDIT... D'OH! I made an error in the drop array - I forgot to encapsulate the color array.

[h-]

It's giving the same error??
Where/how do you execute this script??

This hardly is an engine limitation, I've used/seen used much much more complicated stuff with no probs...

Hey there !


Considering that in .sqf files "there's no such thing as time" (quote from snYpir's Tut', I suspect that the drop command, which defines many time parameters, is structurally incompatible with the format of functions.

Of course, I might be, and hope I am, wrong.

Good luck,

Igor

This was partly my fault, I made a bug in the drop-section. Here's the correct version -

private
[
   "_soldier",
   "_ammo",
   "_shot",
   "_pos"
];
_soldier = _this select 0;
_ammo = "Bullet7_6";
_shot = nearestObject [_soldier,_ammo];
_pos = getPos _shot;
_x = _pos select 0;
_y = _pos select 1;
_z = _pos select 2;
_maxPuffs = 1;
_i = 0;

while {_i < _maxPuffs} do

{
drop ["cl_basic","","Billboard",1,8,[0,0,0],[(velocity _soldier select 0) / 2 + random 0.7 - random 0.7,(velocity _soldier select 1) / 2 + random 0.7 - random 0.7,0 + random 0.5],0,1,0.8,random 0.1,[0,3,4,5],[[[0.85,0.85,0.85,0.05 + random 0.05],[0.85,0.85,0.85,0]]],[0,1,0,1],0,0,"","",_shot];
_i = _i + 1
}

However, I did mess around with a working version which I couldn't get to work, either.

EDIT again... it seems that it was actually the forums that f'd up the array...?!

[Igor Drukov]

So drop works in functions ? Awesome !   ;D

[Nemesis6]

The drop-array does indeed work in functions. If it didn't, gun-barrel smoke would not be possible.
