LSValmont 789 Posted April 29, 2019 vSuppress Script by Valmont and George Floros is the first script based Audio-Visual Suppression effects for Arma 3. vSuppress Main Features: - Easily add Suppression effects to your missions. These audio visual effects will trigger on players when Ai Units' bullets land or pass near them simulating the "Fear Effect" of being shot, the anxiety caused by being pinned down or just general combat stress. - Fully Multiplayer Compatible! - Extremely lightweight. The script was conceived with performance in mind and on testings with 60+ Ai units shooting at a single player resulted in a meagerly 2 FPS negative impact. - The Suppression effects are purely cosmetic and will not cause any other effects on players such as decreased stamina, stats etc. - The sounds and the visual effects can be easily tweaked and disabled inside the script. - Players cannot suppress other players, only Ai Units who have the script/EH running will be able to suppress players. - The suppression effects are quite minimalist and fast in nature to keep Arma 3's gameplay unchanged while adding an additional layer of immersion to the game. Requirements: Spoiler - Basic Mission Editing knowledge. (For adding the commands to the unit's init etc). - Nothing else 😉. Usage: Spoiler There are two versions of the script: - vSuppressAll.sqf that runs from your missions' init.sqf and sets the variables and eventhandlers for all enemy Ai units present at the start of the mission. - vSuppressUnit.sqf that can be used to add the script to a single specific Ai Unit or for adding the suppression effects to units that spawn via script or after mission start. vSuppress version 1.1 DEMO MISSION DOWNLOAD LINK: https://drive.google.com/open?id=1NLZx5lH_G5p6ubcK73xvwwgYVqCWpdvL Notes: Spoiler - vSuppress was born out of the need of an "out of the box" thinking regarding projectile impact tracking in Arma 3 that is both performance friendly, accurate enough and does not create dependency on additional mods/addons. (Since native solutions such as a ProjectileImpactEH currently does not exist in Arma 3). Most if not all current mods dealing with Suppression rely on loops that track the position of the bullet projectiles almost in realtime and until they loose velocity or cease to exist, checking its positions and velocity all the way up to that point. This approach was accurate but fairly impractical in terms of resources used and also in terms of multiplayer environments where Arma 3 calculations can often go wrong under low FPS/Latency scenarios. In fact in our MP testing scenarios the solutions using the projectile tracking loop could result in a loss of up to 10+ FPSs during heavy combat situations versus the 2 FPS loss of vSuppress. - To work under MP environments and without a noticeable performance impact vSuppress took a unique approach on the matter by using a cleaver solution conceived by George Floros that consisted in using the assignedTarget command and complemented by Valmont's weaponDirection currentWeapon vectorAdd vectorMultiply to actually predict the potential future location of the projectile instead of actually tracking the real projectile (expensive). 2 1 Share this post Link to post Share on other sites
genesis92x 810 Posted April 29, 2019 Try changing _projectile call bulletCheck; to _projectile spawn bulletcheck; I didn't think while {} do {} could be called, as the engine halts for the code to execute first. Further down the line, I'd add some way to not have the function be called every time an AI fires. It will cause death and chaos due to FPS drain otherwise. 1 Share this post Link to post Share on other sites

I think that you should just change , your think on how to use this. Since it's a script that affects players, then you need to run this code in the initPlayerlocal and not on every enemy. Then check the EH again for "FiredNear" because you want a certain distance as i see. I don't think that you need to remoteexec anything. You don't need either a while true for the pp effects. 1 Share this post Link to post Share on other sites

The problem is that "FiredNear" only detects if the shooter was close, not the actual bullet, so if you get fire from an AI unit who is far from your playerUnit you won't get the suppression effects... The problem with Arma 3 is that it is very complicated, as far as I know, to detect where a bullet hits. In every single suppression script/mod I check they use the "Fired" EH. The problem is that all those mods and scripts are more complex and use more FPS that what I want with this script. Share this post Link to post Share on other sites
johnnyboy 3797 Posted April 30, 2019 Looping to track bullet pos feels expensive to me. You could reduce that by checking angle of shooter to player first to see if within a 5 degree tolerance first. Could save some FPS. BIS_fnc_inAngleSector You could also check line of sight from shooter player. If both line of sight and inAngleSector good, then that might be enough data for you to consider the bullet near the player without ever checking the bullet. 1 Share this post Link to post Share on other sites

So far I get no errors and everything seems to work when I run the commands individually but as a whole I cannot get the suppression effect to show for players. I think I am way over my head now so I've requested help from the master... https://forums.bohemia.net/forums/topic/215280-i-saw-a-video-of-a-ballistic-tracer-script-that-showed-the-projectile-with-a-dot-where-can-i-find-that-script/?do=findComment&comment=3353475 I hope we can make this work. So far the only good suppression effects come from mods and quite expensive in terms of network/processing. I want this script/EH to be as light as a feather 😃 Share this post Link to post Share on other sites

LSValmont 789 Posted April 30, 2019 2 minutes ago, GEORGE FLOROS GR said: What you want is a little bit of this , right ? Yes sir, something similar to that but: - In script format. - Without any config options that could make players just deactivate or reduce the effects. - Not as invasive. The effects are quite minimal yet enough to feel the "danger" of the situation. - And finally the code has to be leaner than that of the mod. I have checked laxemann's code a lot and it writes a lot of variables for its cumulative suppression, it is good but quite redundant for the needs of this SUPER SIMPLE SUPPRESSION SCRIPT. What I am trying to do is a lot simpler and should be a lot faster too. 1 Share this post Link to post Share on other sites

Last time I used that EH it only fired if the enemy was really close... Will spawn some enemies over 200mtrs to see if the effects are still there. PS: This will also fire if you shoot or if an ally shoots so more conditions will be needed. 1 Share this post Link to post Share on other sites

LSValmont 789 Posted April 30, 2019 1 minute ago, GEORGE FLOROS GR said: check : FiredNear won't work George. Just tested it. Your unit needs to be very close to the unit that is firing for the EH to execute. So I placed a barricade, my player and then a enemy 200mtrs away on the VR map. The enemy would start to shoot and I will get no blur effect nor the systemchat until I get lets say 20 meters from that unit and then it fires. It would be great to have a "HitNear" or "BulletNear" eventHandler but we don't. 😓 1 Share this post Link to post Share on other sites

It would if we could increase the range from the unit firing to the player that the FiredNear checks... but I don't think that is possible. There was an approach of having a loop on the player checking for nearby bullet impact effects but that could be performance intensive I think. Our best bet is perhaps checking the trajectory of the bullet and if the trajectory ends up close to a player then the effects fire. johnnyBoy suggested https://community.bistudio.com/wiki/BIS_fnc_inAngleSector but I have no idea on how to use it. Nor could I find a script using it. Share this post Link to post Share on other sites

Seems to be a good alternative! Do you know if it will work in MP? Since mine uses remoteExec it surely works. Also the other advantage of my approach is that it can suppress more than one player if the bullet landed near them. Also another advantage of my approach is that it fires even if you are hidden from the Ai. But yours is probably a lot less resource intensive. (Any Idea how we can test the fastest one?) 1 Share this post Link to post Share on other sites
