Improved Bullet Cam Script v1.1

[Big Dawg KS 6]

Here is an update to this script due to a few requests.

Changes from previous version (1.0):

-Added following global variables (uses can be found in comments):

BDKS_BulletCamNoBlur, BDKS_BulletCamFOV, BDKS_BulletCamAccTime, BDKS_BulletCamNoParticleFX

-Added BDKS_ShowBulletCamToPlayer unit variable (see comments for use)

-Added particle effect (nothing too fancy, I like it but I'm open to suggestions)

-Added ability to terminate bullet cam in flight with key for ironsights/optics

-Added blackin/blackout effects for smoother transitions

-By default, player only sees bullet cam when he fires (see BDKS_ShowBulletCamToPlayer)

-Added check to abort cam script if projectile not found

Untested in Multiplayer. MP behaviour unknown.

See comments for more info.

Nice one Big Dawg!

[p75 10]

Dawg, you are the One ;-)

Great work, I'll test it today! Thanks, mate!

Will test it now, after a quick glance of the list of options (great work, am impressed) the only thing I'd like to see is camera position to the target as a variable. Get my drift? I'll update in a hour if all runs.

Grtz

Dawg, I think you have outdone yourself, some suggestions:

- Bullet is shown from behind/low point camera angle. I would like to see hanging over the bullet sort to speak, say at a 30-45% angle. Because now sometimes you don't see the upper body when the bullet impacts.

- The camera focus on the target. Could you make that into a variable which is adpatable? Because now the Target is really upclose.

Small bug:

- The cancel option did not work, which overhere is the right mouse button. I can't cancel the cam.

Besides these points, it is simply amazing, very well done, sir! Appreciating your effort to make Arma 2 a better experience, two thumbs up!!!

Highly recommended for all Snipers/Pilots!

PS: Dawg, if one wants to disamble the blur effect where do you add the line :set BDKS_BulletCamNoBlur = true

The camera focus on the target. Could you make that into a variable which is adpatable? Because now the Target is really upclose.

Use BDKS_BulletCamFOV. Increase it for less zoom, decrease it for more (default is 0.05).

The cancel option did not work, which overhere is the right mouse button. I can't cancel the cam.

Like I said it can only be cancelled while the projectile is in flight, after it hits something you can't skip the 1-2 second shot of the impact. If it still doesn't work, it may be related to using the mouse (I don't use default control mapping), try using Num 0 (which is also ironsights/optics key by default IIRC).

Bullet is shown from behind/low point camera angle. I would like to see hanging over the bullet sort to speak, say at a 30-45% angle. Because now sometimes you don't see the upper body when the bullet impacts.

The problem is that the bullet does not rotate at all while in flight (its orientation remains fixed regardless of trajectory), and camera is attached relative to the direction of the round, not it's trajectory. If I were to change this, math (specifically trig, which I'm a bit rusty with) would be involved. Of course I could still add a variable to change the angle of the camera relative to the round, though this problem will still exist.

PS: Dawg, if one wants to disamble the blur effect where do you add the line :set BDKS_BulletCamNoBlur = true

Init field will work:

BDKS_BulletCamNoBlur = true

Mucho Gracias, Dawg, thank you for the input, simply superb!

I highly recommend this addon!!!

Sounds promising.

Instead of using the orientation of the bullet, you can use it's velocity vector to determine the angle.

Like this: (velocityvector / bulletspeed * distance) <-- rotated around 120° and used as modelcoordinate for positioning the camera. AFAIK we have an BIS_function for rotating vectors.

Instead of using the orientation of the bullet, you can use it's velocity vector to determine the angle.

I know, but if you look at my code I'm using camSetRelPos to save me the trouble of doing any calculations. I know I could use the velocity, I implied that in my previous post, but like I said my math is a bit rusty and it's not a serious enough problem for me to go through the effort to change it (plus then the code would become a lot more complex, and I'm trying to keep it as simple as possible).

AFAIK we have an BIS_function for rotating vectors.

That's cool, I wrote a few functions for ArmA to rotate vectors since at the time the math was fresh in my head (linear algebra is actually quite simple), but have since forgotten it all. It's been so long since I'ved used my (at one point well developed) math skills, in addition to a recent lack of interest (I used to actually enjoy this stuff... sigh), that they've completely degraded.

Thanks guys, but changing the fov does the trick, I set it to 0.3 instead of 0.05.

Gotta say it is awesome, really impressed by the results!!! Although, the no blur is better in my opinion. But that is a matter of preferences.

All I gotta to say is that this comes highly recommended and I appreciate your hard work, it could not be more perfect:

THANKS

[Tajin 348]

in addition to a recent lack of interest (I used to actually enjoy this stuff... sigh), that they've completely degraded.

;) I know what you mean. Got exactly the same problem sometimes.

[Big Dawg KS 6]

I find the blur to be more immersive on aircraft ordinance (ex. bombs).

I highly recommend this addon!!!

I don't want to call this an addon, but a useful tool for editors. They can modify it or take pieces from it to use for their own purposes. Anyone is free to use my code as they see fit, I'd prefer you credit me but then again there are times where I myself don't credit other people's code so I have no right to demand it of you.

I know what you mean. Got exactly the same problem sometimes.

For once, I think video games are actually to blame here... how ironic. :o

It says in the comments:

Cool, got it to work! Thanks!

[p75 10]

Dawg,

Small bug:

There is an issue with the NVgoggles. When activated you don't get the bullet cam unless aimed high and then when you do get it while aiming high you get the bullet flight without NV filter. Could you please address it?

Thanks!

[MJK-Ranger 0]

Thanks:thumb::cheers:

[Redfield-77 10]

Great script. I used your last version and I liked the slow-mo. I see where I can adjust the speed but It will stay at that speed if I change it. How would I make time go back to normal after impact?

Update on testing:

Another bug:

When your soldier is higher than the target (say on a mountain ) and you are shooting in a downwards angle the script does not work. Could you please address it.

[p75 10]

Update - bug:

I don't have all the rocket classnames, but none of the airplanes/helis work with the script.

[Big Dawg KS 6]

Vehicles will only work if you add the eventhandler to the vehicle itself, not just the crew.

F35 weapons are in the script already, more can be added.

Dawg, I did both, hmm, maybe I misspelled some name? You have a list with all the rocket names?

You know what the issue is with aiming at something below?

[nuggetz 0]

Has the above issue been addressed?

[Big Dawg KS 6]

Here's a new (untested) version that will A. hopefully allow you to eliminate the problem where the script cannot acquire the projectile and B. allow you to define supported weapons without modifying the script (via a global variable).

Read the comments for details.

This is a beta (untested):

// Alternatively, for higher velocity projectiles (where the script has trouble acquiring the projectile),
// call with this syntax:
//   this addEventHandler ["fired",{_this+(nearestObject [_this select 0,_this select 4]) execVM "cam.sqf"}]
//
// To exit the camera ingame (while in flight), press the key for ironsights/optics
//
// To add supported weapons, add MUZZLE classnames to _list (note: classnames are CASE SENSITIVE).
// Alternatively, declare a global array called BDKS_BulletCamList with muzzle classnames. Ex:
//   BDKS_BulletCamList = ["huntingrifle","Javelin"]
//
// To disable bullet cam, set BDKS_DisableBulletCam = true
//
// To disable blur effects, set BDKS_BulletCamNoBlur = true
//

Need help, i want to use this script together with "targetrange" mod -->http://www.armaholic.com/page.php?id=6505

The "targetrange" mod is installed and working. How do I use your script together with the mod so I can see where my bullets are flying to.

I made a file "cam.sqf" where i pasted your script into and put it in the "targetrange mod" folder, what then???

P.S. "targetrange mod" is not put in missions dir like other missions, its to be used in editor; so you put it in ex. C:\Users\name\Documents\ArmA 2\missions

Thanks in advance

You can just paste this in the player's init:
