LtShadow 41 Posted August 6, 2013 Moderators, this is not a double post, nor cross post. I am simply moving this topic to this area due to another member advising me asking for help here! Hello! I am trying to get a 'Sonic Boom' to play when a plane I am working on hits a certain (called for) speed. I have already tried lots of methods that have gotten me somewhere, but not to the working point. Please have a look at these codes; Common_Init Code: _plane = _this select 0 #Skip [_plane] execVM "\mig29\scr\AircraftEffects.sqf" [_plane] execVM "\mig29\scr\AircraftBoom.sqf" exit AircraftBoom.sqf Code: //SonicBoom script by LtShadow //Do not re-distribute unless you ask permission! // _veh = _this select 0; //the vehicle _spd = 500 select 0; //the speed at which the sonic boom occurs _boomed = false; class CfgSounds { sounds[]= {sonicboom}; class sonicboom { name = "sonicboom"; sound[] = {\mig29\tornado_gr4boom.wss, 200, 1.1,}; titles[] = {}; }; }; while {alive _veh} do { _vel = velocity _veh; _speed = 3.6*sqrt((_vel select 0)^2 + (_vel select 1)^2 + (_vel select 2)^2); hint format ["Speed: %1",_speed]; if (_speed > _spd and not _boomed) then { _veh say3D "sonicboom"; _boomed = true; }; sleep 0.5; }; ArmA 2 script I am trying to base this off of; Code: /* */ _veh = _this select 0; //the vehicle _spd = _this select 1; //the speed at which the sonic boom occurs _boomed = false; while {alive _veh} do { _vel = velocity _veh; _speed = 3.6*sqrt((_vel select 0)^2 + (_vel select 1)^2 + (_vel select 2)^2); hint format ["Speed: %1",_speed]; if (_speed > _spd and not _boomed) then { _veh say3D "sonicboom"; _boomed = true; }; sleep 1; }; Init line of unit in mission (arma 2) nul = [this,70] execVM "monitor.sqf"; Monitor.sqf is the 'SonicBoom' script I had put above this.

Not sure how exactly to do that though, the guys over on Configs and Black Magic would know more. :) Then however you're running into a situation where you, the server and everyone playing needs to have the proper version of that addOn for it to work. Is this for your F-14 port? You'd wanna add the sound to the addOn and the config to the cfgSounds in your config for the plane. I'm not sure how to get the monitor script to work with an addOn though. Yes, I am trying to make this work ALL IN ONE, so that I do not have to call any scripts with a mission/trigger in the editor (all pre-set variables in the config). Thank You!

LtShadow 41 Posted August 7, 2013 Okay, I tried to implement the say3D command, again, with no joy. Anyone out there know how to activate a sound (In the pbo) at a certain speed without having to make a separate mission file? Share this post Link to post Share on other sites
LtShadow 41 Posted August 8, 2013 Actually, I am nearly completed with this, but am getting a Error - Generic Error in Expression ; Sleep 1 in this code - //SonicBoom script by LtShadow //Do not re-distribute unless you ask permission! // _veh = _this; //the vehicle _spd = 500; //the speed at which the sonic boom occurs _boomed = false; while {alive _veh} do { _vel = velocity _veh; _speed = 3.6*sqrt((_vel select 0)^2 + (_vel select 1)^2 + (_vel select 2)^2); if (_speed > _spd and not _boomed) then { _veh say3D "mig29\snd\tornado_gr4boom.wss"; _boomed = true; Sleep 1; }; }; Then, when I just set a init in a vehicles code 'this exec "AircraftBoom.sqf";' it gives me an error saying Error - }; must have { Weird.

John Kozak 14 Posted August 9, 2013 (edited) Hey there, LtShadow. Unfortunately, you fell victim to common misconception :) There's no sonic boom when an aircraft "passes" certain velocity. Rather, there's a cone of high pressure (shock wave) which is moved with the plane itself. The "boom" itself happens when this cone is dragged over the observer - i.e. effectively the observer is hit by the shockwave. See: http://en.wikipedia.org/wiki/Sonic_boom#Perception_and_noise However, as those who have witnessed landings of space shuttles have heard, when the aircraft is nearby the sonic boom is a sharper "bang" or "crack". The sound is much like the "aerial bombs" used at firework displays. It is a common misconception that only "one" boom is generated during the subsonic to supersonic transition, rather, the boom is continuous along the boom carpet for the entire supersonic flight. As a former Concorde pilot puts it, "You don't actually hear anything on board. All we see is the pressure wave moving down the aeroplane - it gives an indication on the instruments. And that's what we see around Mach 1. But we don't hear the sonic boom or anything like that. That's rather like the wake of a ship - it's behind us.". That's not an attack on the work itself, I'm just pointing out that it may be worth changing the direction a little. As for your script, you should write while {!alive _this} do { instead of while {!alive _this} then { Edited August 9, 2013 by DarkWanderer Share this post Link to post Share on other sites

See: http://en.wikipedia.org/wiki/Sonic_boom#Perception_and_noise Actually, yes there is! :) When the plane reaches the point of sound, a very high pressure shock wave starts to cone around the aircraft, once the aircraft passes this point is when the 'Boom' occurs. haha, even though it may not be realistic, I just want to figure this darn thing out! Tired of nonsense answers. The only useful one here is Gnat (and Foxhound because he is le* Moderatorr). Thank You.

John Kozak 14 Posted August 9, 2013 When the plane reaches the point of sound, a very high pressure shock wave starts to cone around the aircraft, once the aircraft passes this point is when the 'Boom' occurs. Nope, still wrong ;) But it would be a nice start, nevertheless.

LtShadow 41 Posted August 9, 2013 Nope, still wrong ;)But it would be a nice start, nevertheless. How are you calling your script? Something like this? I am not calling the script. Period. Actually, I am using this .sqs file in the planes script folder: _plane = _this select 0 #Skip [_plane] execVM "\mig29\scr\AircraftEffects.sqf" [_plane] execVM "\mig29\scr\AircraftBoom.sqf" exit This is where it inits all the scripts. :) Share this post Link to post Share on other sites

LtShadow 41 Posted August 11, 2013 Okay guys, have collaborated with another scripter and he can't figure it out (No, it wasn't ZooLoo because he is busy with other stuff). I am so close, I can taste it! This has to do with the if !alive _This statement; please read! (As you can tell, me and my buddy totally re-vamped this code , I did most of the work anyways) _boomed = false; _veh = _this; if (!alive _this) then { if (speed _this >= 760 and not _boomed) then { _veh say3D "bBoom"; _boomed = true; }; sleep 1; }; The Say3D is already set up, as well as the speed _this function (as it is a standard .sqf function and No MISSION NEEDED!) This is the error I get when I start up my game with the MIG; Error in expression <" _boomed = false; _veh = _this; if (!alive _this) then { if (speed _this >= > Error position: <alive _this) then { if (speed _this >= > Error alive: Type Array, expected Object File mig29\scr\AircraftBoom.sqf, line 5 If ANYONE knows what the problem is, please let me know ASAP (Tired of working on this).

zooloo75 834 Posted August 11, 2013 What is _this equal to? _this needs to be an object - it looks like you are sending an array. If you are putting this in an init line then do... _sonicBoom = this execVM "SONICBOOMSCRIPTNAME.sqf"; I'm assuming you did this... _sonicBoom = [this] execVM "SCRIPT.sqf"; ----- Now for some logic. Why would the sonic boom only occur when the vehicle is "dead"? You'd also want to put the script into a loop so it will continuously check for that condition. Right now you have it check only once (as soon as the mission starts) which means you'll never see the sonic boom. Share this post Link to post Share on other sites
