Need help with scripting

[Cakefirst]

Ok, I thought I had got a working script for making the leak stop by turning the wheel but all I managed was to stop the sound when turning it, the particle wont disappear, I still dont find any way to do it. Also I have put out a statue more specifically called deformed_man. What I am trying to do is find a way so when you see it your screen will shake breafly and you hear your breath and sanity goes up as you go scared. I think I got it figured out how the sound will work but I have no clue of how to make character screen shake and sanity goes up and combine it with this prop? Any help appreciated

This is what I got for my leak, it only stops the sound

void LeakValve(string &in EntityName, int alState)
{
if (alState == 1) {
if(GetLocalVarInt("LeakDone") == 0) {
SetLocalVarInt("LeakDone", 1);
for (int i = 0; i < 26; i++) {
DestroyParticleSystem("leak"+i);
}
StopSound("leak_sound1", 2);
SetLocalVarInt("isLeakOn", 0);
GiveSanityBoost();
