Grumpy Old Man 3546 Posted November 15, 2016 GOM - Ambient AA V1.2.1 Purpose of this script: Gives mission makers access to simple and versatile ambient AA fire. Features: Takes pre placed vehicles and uses their main guns to engage AA fire at simulated targets for the given duration. Works fine with static MG turrets (raised) and multiple third party vehicles. It's also possible to immediately stop the script and free up all units to fire on actual threats. For the duration of the ambient AA vehicles will check for a clean line of sight, so they don't mindlessly fire into terrain/objects. If more than half of the assigned vehicles have no line of sight to the simulated target they'll simply pick another one. You can also add and array of positions (ASL) to make the guns fire at them randomly. How to use this script: At first copy the spoiler contents into a file inside your mission folder and name it accordingly. scripts\GOM\ambient\GOM_fnc_ambientAA.sqf: //V1.2.1 GOM_fnc_ambientAA = { params [["_battery",""],["_duration",1],["_customRounds",[0,0,0]],["_positions",[]],["_spread",150]];

Demo Mission 1.2.1 Armaholic 1.2 Known Issues: None so far. Changelog: V1.2.1 Fixed: Vehicles that had missiles selected as default would not fire V1.2 fixed weird bug that stopped the guns from firing since tanks DLC (had to remove a sleep at the beginning(!) of a waituntil, go figure) added parameter to allow a custom amount of rounds to be fired each salvo fixed error when crew bails out (thanks @Zer0cool and @AZCoder) Previous changes: Spoiler V1.1.3 Picking random position to shoot at, if no position has been declared V1.1.2: Fixed positions params default value V1.1.1: Fixed wrong _debug value V1.1: Added parameters to make the guns fire at predefined positions Fixed some vectorAdd mishaps Enjoy! 13 Share this post Link to post Share on other sites
johnnyboy 3795 Posted November 15, 2016 Hey GOM, that is great. You've made it very simple for adding ambient combat to missions and went the extra mile so these units can engage actual threats they perceive. Well done. 1 Share this post Link to post Share on other sites

hunne 1 Posted November 16, 2016 wow, this looks awesome, thx GOM do they randomly aim or can I actually have them fire at a specific location or a series of locations? Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted November 16, 2016 They usually fire at simulated moving targets, another random fire mode is making them shoot at random static positions roughly above them. I'll add an option to make them fire at a reference point with definable random distance and add further customization. Cheers Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted November 22, 2016 have them fire at a specific location or a series of locations Updated to V1.1 and added this to the script. Cheers Share this post Link to post Share on other sites

Bamse 223 Posted November 22, 2016 Hey Grumpy! After testing this I only got "Aborting AA!" when executing the script. I switched true and false between lines 19 and 24 and then stuff works as it should. I really like the script tho, cool way to add some ambiance. Good job! 1 Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted November 22, 2016 Weird, for some reason I forgot to set those variables back to the intended values... Thanks for spotting that! Updated the script. Cheers 1 Share this post Link to post Share on other sites

kvntvan 13 Posted November 25, 2016 Hello, have you tested this script on a dedicated server? I'm making a mission where a signal intelligence team has to spoof a radar transmission to "bait" an AA gun into firing and revealing its position, clearing it for an arty strike. I have your script attached to one Tigris named "AA1" and a satellite phone named "hack" with an addaction code spoof = [[hack,["Spoof Radar Transmission","scripts\spoof.sqf"]],"addAction",true] call BIS_fnc_MP; that activates a script called "spoof.sqf" with your code in it and another line of code to show a hint _AA = [[aa1],1] execVM "GOM_fnc_ambientAA.sqf"; ["False Radar Transmission deployed","hint",true,true] call BIS_fnc_MP; it works fine in the editor and when I host my own MP server off my machine, but when I test it on our groups dedicated server the hint displays without the gun firing. would you happen to have any idea whats causing this?

Bamse 223 Posted November 25, 2016 I've tested and used it on dedicated several times by calling it exactly like the first post and it works well (with the modifications as of v1.1.1) 1 Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted November 25, 2016 I didn't test it on dedicated myself but should work just fine, as Bamse stated. Cheers Share this post Link to post Share on other sites
Mosshadow 5 Posted November 30, 2016 I was trying to test out the script but it seems that the vehicles and turrets are not firing. The debug mode shows that the script is working but nothing is happening. Is there a long delay before they fire? Share this post Link to post Share on other sites
Grumpy Old Man 3546 Posted November 30, 2016 How are you calling the script? If you specify custom positions (guessing from the screenshot) to fire at, make sure they're ASL, it looks like you used getposATL instead. Cheers Share this post Link to post Share on other sites
Mosshadow 5 Posted December 1, 2016 How are you calling the script? If you specify custom positions (guessing from the screenshot) to fire at, make sure they're ASL, it looks like you used getposATL instead. Cheers I do not believe I am specifying a target right now, I copied the code from the example given and just removed the extra items. EDIT: I tried again this time I did put in coordinates instead of leaving the item blank and it is firing. How do I get it to fire without having Positions?
