How to make wing tip mounted guns fire...

[rip31st 98]

I'm currently in work on a fixed wing fighter which has four wing mounted machine guns. Is it possible to get all four to work? I know I can get two working so far.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

_u = _this select 0

_ammo = _u ammo (_this select 1)

_b = nearestObject [_u, _this select 4]

? (((_ammo mod 2) == 0) and (_b isKindOf "MG17")) : _offset1 = [0.2 , 3.3 , 0.53];_wpos1 = _u modelToWorld _offset1;_b setpos _wpos1

exit

You need to mod by the number of MGs.  Eg:<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_u = _this select 0;

_ammo = _u ammo (_this select 1);

_b = nearestObject [_u, _this select 4];

?!(_b isKindOf "MG17") : exit

_n = (_ammo mod 4);

? (_n == 1) : _offset = [0.2 , 3.3 , 0.53];

? (_n == 2) : _offset = [offset2...];

? (_n == 3) : _offset = [offset3...];

_wpos = _u modelToWorld _offset;

_b setpos _wpos;

exit

That way, bullets 0, 4, 8, 12 all come from the model's muzzle, 1, 5, 9, 13 come from offset1, 2, 6, 10, etc from offset2, 3, 7, etc from offset3.  If you have trouble w/ that let me know

What fixed wing plane you making ??

In OFP I experimented with multiple firing spots and it wouldn't keep up with the speed of the plane.

ex: flying at 600kph the firing would be coming from behind the plane

Would it be possible to shoot your own plane in that case?

Thanks for the code. I will give it a shot later and report back on the results.

Only have bullets coming two machine guns - from the right wing offset and center:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

_u = _this select 0;

_ammo = _u ammo (_this select 1);

_b = nearestObject [_u, _this select 4];

?!(_b isKindOf "MG17") : exit

_n = (_ammo mod 4);

? (_n == 1) : _offset = [0.2 , 3.3 , 0.53];

? (_n == 2) : _offset = [2.493,3.24,-0.26];

? (_n == 3) : _offset = [-2.493,3.24,-0.26];

? (_n == 4) : _offset = [-2.493,3.24,-0.26];

_wpos = _u modelToWorld _offset;

_b setpos _wpos;

exit

Mod never returns the number.  4 mod 4 is 0, not 4.  So whatever you check w/ _n == 4 will not work.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

_u = _this select 0;

_ammo = _u ammo (_this select 1);

_b = nearestObject [_u, _this select 4];

?!(_b isKindOf "MG17") : exit

_n = (_ammo mod 4);

? (_n == 0) : exit;

? (_n == 1) : _offset = [0.2 , 3.3 , 0.53];

? (_n == 2) : _offset = [2.493,3.24,-0.26];

? (_n == 3) : _offset = [-2.493,3.24,-0.26];

_wpos = _u modelToWorld _offset;

_b setpos _wpos;

exit

When n is zero, the normal spot for rounds to fire from should work.  When n = 1, 2, or 3, it will go to the offset specified.  I've not tested this, but I'm fairly sure it will work.  If it is still giving your problems, but some debug lines in.  Eg: have it give you a hint format ["n: %1\n\noffset: %2", _n, _offset] right after the conditions.

BTW, you may want to consider, after you have it working, converting this to an SQF rather than an SQS script.  But to test it, using SQS is sometimes easier.  Also, if this script is packed into your pbo, that makes making changes difficult.  My advice would be to have your pbo reference a "test.sqs" or something like that.  Then put the "test.sqs" in a mission under the mission editor.  Then, if the script doesn't work well, you just alt-tab, edit the script, then try again.  It saves a ton of time versus rePBOing every time.

Good luck man!

PS: I assume you have the rounds w/ tracers so you can see them. Also, this will not create a muzzleFlash or smoke effect at the other firing points.

Okay the hint is telling me that only the main weapon and offset 2 are firing. Visually confirmed. I am pulling my hair out trying to figure out why # 1 and # 3 aren't firing!

here is the event handler code that activates it:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">fired = "_this exec ""\rip31st_bf109e1\fired.sqs"""

in your weapon config, do you have burst=x; or multiplier=x;? Its possible that if you have a multiplier of say, 2, then instead of having an ammo count of 1, 2, 3, 4, 5, 6... you are getting 2, 4, 6, 8, 10... which would not give the same results when you mod by 4.

[rip31st 98]

That did the trick. In the gun core I changed the multiplier to one, it was at two. Isn't amazing how small things can make a big difference. Thanks for your help! I had a suspicion the problem lied within the config.

Here's the change I made to make it work:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

ammo="MG17";

multiplier=1;

Glad it worked.
