Random Scares

can a switch script determine if the case has been used before?

Switch statements normally check against integer values, and an integer value isn't enough information to check if something has been used before. If statements check against boolean values, normally through the use of boolean operators or values that can be implicitly converted into a boolean value. Unfortunately, AngelScript scripting (at least the version that comes with Amnesia) doesn't implicitly convert other data types into boolean values for if statement conditions.

If I remember correctly it does convert integers to boolean values when evaluating an if condition, at least in terms of 0 being false and anything else being true, as in C, if that's what you meant.

If you test the code:

PHP Code: (Select All)

if(1){} 


You will get the error: Expression must be of boolean type. In C (and many other languages), that would be the same as writing:

PHP Code: (Select All)

if(true){} 


In HPL2 scripting, it's not.

Fair enough then, I thought I had some code in a test map on my home PC where I tried that out thinking it would be useful, but I guess not...

Correct me if I'm wrong, but I think you could add local (or global) variables and an "if" statement to restrict how many times/if the case is used more than once. I'm not entirely certain since I don't fully understand how the original script works.

What I think I'm saying up ^ there:

Code: (Select All)

///*insert opening part of switch script here*////
if(GetLocalVarInt("Scare1Played") == 0)
{
       *insert the scare script*
       SetLocalVarInt("Scare1Played, 1);
}

if (GetLocalVarInt("Scare1Played") == 1)
{
   /////whatever else you want here/////
}
/////rest of script below/////

Is that in any way possibly right, or should I just go home and focus on mapping?

Edit: just realized I put the same == number, thanks Robosprog

You can definately do it like that, but if you looking at having 5+ different events, all of which you need to keep track of, it's going to get very inneficient (but not really a problem*) to keep them all in seperate variables.

Doing it you're way would look more like...

Code: (Select All)

void PlrCollideSwitch(string &in asParent, string &in asChild, int alState)
{
int x = RandInt(1, 5)
switch(x)
{
case 1:
    if (GetLocalVarInt("Scare1Done") == 0) {
    //Scare 1
    SetLocalVarInt("Scare1Done", 1);
    }
    break;
case 2:
    if (GetLocalVarInt("Scare2Done") == 0) {
    //Scare 2
    SetLocalVarInt("Scare2Done", 1);
    }
    break;
case 3:
etc etc...

* the possibility for hard-to-track bugs is pretty high doing it like that. It's ok if your ready for it

Your's adrianis isn't enough.

You're gonna need a if(GetLocalVarInt("Variable") == 1) too to get
{
int x = RandInt(1, 5)
switch(x)

}

this again

Not sure quite what you mean. The RandInt will be generated again if the function is called again.

If you're saying you need to repeat the RandInt call to get a number that has not been used already, that's a whole other issue.

if(asTimer == "PlayerAh")
{
int AhVariable = RandInt(1, 2)
switch(AhVariable)
{
case 1:
PlaySoundAtEntity("Aaaah1", "player_react_guardian1.snt", "Player", 0, false);
AddTimer("PlayerAh", RandInt(10, 20), "Ambience");
break;

case 2:
PlaySoundAtEntity("Aaaah2", "player_react_guardian2.snt", "Player", 0, false);
AddTimer("PlayerAh", RandInt(10, 20), "Ambience");
break;
}
}

This is my script.
Why am i getting an error, that it expected a ; at the highlighted text?

Don't worry, this is not my whole script file. I know this single passage wouldn't work in any way. It's a part of a timer, as you see in the top of the script

TRY

if(asTimer == "PlayerAh")
{
int AhVariable = RandInt(1, 2);
switch(AhVariable)
{
case 1:
PlaySoundAtEntity("Aaaah1", "player_react_guardian1.snt", "Player", 0, false);
AddTimer("PlayerAh", RandInt(10, 20), "Ambience");
break;

case 2:

break;
}

I tried. Now just nothing happens
