Hey not to narco-post on this thread, but can someone provide me with a simplified script just to have the whistle sound emitted before impact for mortar fire? I'm very novice when it comes to scripting. I have a mission set up with two mortar teams and I'd like to have the cinematic effect of the whistling before projectile impact. I'm not familiar how to use eventHandler in conjunction with playsound3d, or any of this scripting stuff for that matter. I saw mrcurry had figured it out but his dropbox link is down. Any help would be appreciated.
