[SOLVED] switch statements

[DRedshot]

I just read a thread here. I decided to make a new thread because his question has already been answered.

basically, ive never used switch before, because ive never known how to use it, until now. But apparantly 'case' only works with integers, so i couldnt do for example: case asEntity:

but my question is: could i do this with a switch command

Code: (Select All)

void RandomFunction()
{
AddTimer("1" , 1.0f , "Timer");
AddTimer("2" , 2.0f , "Timer");
AddTimer("3" , 3.0f , "Timer");
AddTimer("4" , 4.0f , "Timer");
}
void Timer(string &in asTimer)
{
switch(asTimer){
case 1:
// Do Stuff
break;
case 2:
// Do More Stuff
break;
case 3:
// Do Other Stuff
break;
case 4:
// Do Funky Stuff
break;
}
}

Or would i have to declare asTimer as an integer?
it would make timers much less boring - thanks!

I like to use fEventSpeed to set the time between each case, but this switch thing can be done in various ways (copied this style from frictional)...

Code: (Select All)

void RandomFunction()  //this thing here shows that you can start this thing from anything
{AddTimer("tostarthetimer" , 0.0f , "Timer");}

void Timer(string &in asTimer) //must be timer in this
{AddLocalVarInt("Stage", 1);
float fEventSpeed = 1.0f;
    switch(GetLocalVarInt("Stage"))
    {    case 1:
            //dostuff
            break;
        case 2:
            //Do More Stuff
            break;
        case 3:
            //Do Other Stuff
            break;
        case 4:
            //Do Funky Stuff
            break;
        }
if(GetLocalVarInt("Stage") < 5)   AddTimer("loopiething", fEventSpeed, "Timer");
}

Another way of using switch (I dont really like this way ^^)

Oh now I get what you actually meant... Mybad this was completely offtopic!

Thanks for radding off on my wiki page!

I'm not sure what radding means, but I guess its something negative. I just happen to like the event speed thing more, x == stuff seems scary to me!

OnTopic:

void Timer(string &in asTimer)
{SetLocalVarInt("whatcase", asTimer);
switch(GetLocalVarInt("whatcase"))
{case 1:
// Do Stuff
break;
case 2:
// Do More Stuff
break;
case 3:
// Do Other Stuff
break;
case 4:
// Do Funky Stuff
break;
}
}

should do it

thanks Khyrpa, i don't think it was completely off topic!
as for the other way

That is exactly what my original post is about, I don't like using:
if(asTimer=="Time1"){// do stuff}
else if(asTimer=="Time1"){// do stuff}
else if(asTimer=="Time1"){// do stuff}
else if(asTimer=="Time1"){// do stuff}
because you end up with loads of curly brackets, and loads of lines of code. My original question was how to use the switch statement to do the above code in a neater way with less brackets

edit, just read your second post, i think this thread is solved. Thanks!

The cases don't have to be integers. You can do this

Code: (Select All)

AddTimer("timerone", 1, "TimerFunction");
AddTimer("timertwo", 2, "TimerFunction");
AddTimer("timerthree", 3, "TimerFunction");


void TimerFunction(string &in timer)
{
    switch(timer) {
        case timerone:
            //cool stuff
        break;
        case timertwo:
            //cool stuff
        break;
        case timerthree:
            //cool stuff
        break;
    }
}

wow i didn't even know that, thanks palistov. That makes this whole thread pointless...
the only reason I assumed you couldn't use strings is from reading this page. Oh well, thanks everyone!

Just found out that you can't use strings as cases in a switch function. The values needs to be an integer. There's functionality for string use in switch-case functions, but not for AngelScript I guess

Just resort to if statements. I'll try to find a nice way to use switch statements with strings, as I personally think they are much cleaner and easier to read for someone trying to learn from your script.
