I have alittle function here but the sound im telling it to play isnt playing and the particle effects are not working either i think the string is wrong but im not sure what is needed.


void ActivateQuake(string &in item)
{

SetEntityActive("stone_small01_1", true);
SetEntityActive("stone_small01_2", true);
SetEntityActive("stone_small01_3", true);
SetEntityActive("stone_med01_brown_1", false);
PlayMusic("baseap.ogg", false, 0.7, 0.1, 10, false);
PlaySoundAtEntity("","general_rock_rumble", "Player", 0, true);
CreateParticleSystemAtEntity("", "ps_debris_tunnel", "dust_effect_1", false);
CreateParticleSystemAtEntity("", "ps_debris_tunnel", "dust_effect_2", false);
CreateParticleSystemAtEntity("", "ps_debris_tunnel", "dust_effect_3", false);
AddTimer("T1", 6, "Fallin");

}

Edit: ive managed to get the particles working but still no sound
