How to make lightning go off randomly? - Viperdream - 03-27-2011
So I have this room where I want lightning to go off randomly.
This is what I've found in the Rainy Halls map. As this is the onliest one I know that has random events.
Code:
/*Random lightning and thunder at start of level
*/
void TimerThunder(string &in asTimer)
{
AddLocalVarInt("ThunderStep", 1); //What step to play in the event
float fEventSpeed = RandFloat(0.05f, 0.15f); //The default time between steps in an event
switch(GetLocalVarInt("ThunderStep")) {
case 1:
ThunderLights(2,0.05f);
break;
case 2:
ThunderLights(1,0.05f);
break;
case 3:
ThunderLights(3,0.05f);
break;
case 4:
ThunderLights(1,0.05f);
break;
case 5:
ThunderLights(2,0.05f);
break;
case 6:
ThunderLights(3,0.05f);
break;
case 7:
ThunderLights(1,0.3f);
PlaySoundAtEntity("Thunder", "general_thunder.snt", "AreaThunder", 0.0f, false);
break;
}
if(GetLocalVarInt("ThunderStep") < 8) AddTimer("thunder", fEventSpeed, "TimerThunder");
else {
SetLocalVarInt("ThunderStep", 0);
AddTimer("thunder", RandFloat(10.0f, 30.0f), "TimerThunder");
}
}
void ThunderLights(int alIntensity, float afFade)
{
/*Skip parts of a flash everynow and then but not the first strong light
**and not the last "back to normal" light
*/
if(RandFloat(1, 3) == 1 && (GetLocalVarInt("ThunderStep") != 3 or GetLocalVarInt("ThunderStep") != 7)) return;
float fF = 0.2f;
switch(alIntensity) {
case 1:
for(int i=0;i<=5;i++) FadeLightTo("spotthunder_"+i,0.52f,0.55f,0.6f,0.45f,-1,afFade-0.04f);
for(int i=0;i<=7;i++) FadeLightTo("pointthunder_"+i,0.32f,0.35f,0.4f,0.2f,-1,afFade-0.025f);
for(int i=0;i<=3;i++) FadeLightTo("ambthunder_"+i,0.2f,0.25f,0.35f,-1,-1,afFade);
break;
case 2:
for(int i=0;i<=5;i++) FadeLightTo("spotthunder_"+i,0.82f+fF,0.85f+fF,0.9f+fF,0.9f+fF,-1,afFade-0.04f);
for(int i=0;i<=7;i++) FadeLightTo("pointthunder_"+i,0.72f+fF,0.75f+fF,0.8f+fF,0.4f+fF,-1,afFade-0.025f);
for(int i=0;i<=3;i++) FadeLightTo("ambthunder_"+i,0.25f+fF,0.3f+fF,0.4f+fF,-1,-1,afFade);
break;
case 3:
for(int i=0;i<=5;i++) FadeLightTo("spotthunder_"+i,0.92f+fF,0.95f+fF,1+fF,1+fF,-1,afFade-0.04f);
for(int i=0;i<=7;i++) FadeLightTo("pointthunder_"+i,0.82f+fF,0.85f+fF,0.9f+fF,0.5f+fF,-1,afFade-0.025f);
for(int i=0;i<=3;i++) FadeLightTo("ambthunder_"+i,0.3f+fF,0.35f+fF,0.45f+fF,-1,-1,afFade);
break;
}
}Onliest thing that I could understand were the game scripts. But I'm completely lost at the Break and Case. And what is
Code:
void ThunderLights(int alIntensity, float afFade)I'm not asking you to write a script. I merely want an explanation for these things. Google didn't really make it clear for me.
So I was hoping I could get a push in the right direction here

It's a custom function.
The devs could have named it
Code:
void ThunderLights(int a, float b)And to make "random" timers, use RandInt or RandFloat.
If you use RandInt(0, 10); for example it will choose a random whole number between (and including) 0 and 10.

And what is the time between those then?
RE: How to make lightning go off randomly? - Pandemoneus - 03-27-2011
Code:
AddTimer("thunder", RandFloat(10.0f, 30.0f), "TimerThunder");Make the timer function call itself...
