Sequencing Events and Timers

[Khyrpa]

Everything you put inside OnEnter() happen when the map starts everytime,
everything you put inside OnStart() happen the first time you enter the map.

Then about the event you made:
if you use float values (numbers with f behind) you must use decimals ie. 0.5f 1.0f.
You don't need to set the iIntro variable into 0 at start because AddLocalVarInt atomatically sets it from 0 to 1.
To use FadeIn, you have to first use FadeOut.
You can use any name instead of fEventSpeed.

Heres the script (I added preloads cos everyone forgets to add them):

void OnStart()
{FadeOut(0);
AddTimer("IntroTimer", 1, "Intro");
}

void Intro(string &in asTimer)
{
AddLocalVarInt("iIntro", 1); //Adds 1 to iIntro everytime this timer starts
float thisnow = 1.0f; //sets default time for parts: 1 second
switch (GetLocalVarInt("iIntro")) //looks for value of timer
{
case 1: //what it does if the value for iIntro is 1
thisnow = 2.0f;
FadeIn(5);
PlaySoundAtEntity("", "scare_male_terrified.snt", "player", 0, false);
break;

case 2: //if iIntro value is 2
thisnow = .1f;
CreateParticleSystemAtEntity("", "ps_rose_petals_swirl", "player", false);
break;
}
if (GetLocalVarInt("iIntro") <2) //if iIntro value is less than two
{
AddTimer("IntroTimer", thisnow, "Intro");
}
}

void OnEnter()
{
PreloadParticleSystem("ps_rose_petals_swirl");
PreloadSound("scare_male_terrified");
}
