How do I make physical entity, play sound each time, when it touches whatever block or model? I try to use ENABLE_FRICTION, works good, but when object stops moving, sound is still playing...

do you mean the sound plays another time or the sound coninues playing until it finish?

Sound just needs to play one time, only when it impacts with anything.

Any idea guys?

maybe

if(event_type==EVENT_FRICTION)
{
if(!snd_playing(yoursound_handle)) yoursound_handle=snd_play(yoursound, 100, 0);
}else{
if(snd_playing(yoursound_handle)) snd_stop(yoursound_handle);
}

maybe instead of media_play or snd_play you use, media_loop or snd_loop?
I use myself the Enable Friction to let the empty bullets and mag once they fall to the ground play a sound. and it works good. (sound plays only once)

OK, thank you one more time painkiller
