Can you break a script?

[Wancieho]

Is it possible break a script in Flash? Say i'm running about 20 lines, halfway something happens and I want the script to stop at line ten and exit. Is this at all possible?

[chi-styler]

A bit of structured programming, maybe

if(Something happens) {
  //do this code
}

Anything else and it won't..

[C4_Tom]

there is a break command, this may do what you want. It's concidered bad practise by some people though

[chi-styler]

If you were felling crude you could use break; But if it doesn't always need to exit there, you're going to need an if() statement. If it does, whats the point of having code there at all?

[Wancieho]

Okay this was my purpose, this code lies on a button:

<b>ORIGINAL:</b>
on(press){
if(var == 1){
var = 2;
this.happen;
}
if(var == 2){
var = 1;
this.happen;
}
}

<b>POSSIBLE SOLUTION:</b>
on(press){
if(var == 1){
var = 2;
this.happen;
break;
}
if(var == 2){
var = 1;
this.happen;
}
}

Ohh,

You just need

on(press){ 
  if(var == 1){ 
    var = 2; 
    this.happen; 
  }else if(var == 2){ 
    var = 1; 
    this.happen; 
  }  
}

Just an else if

[Wancieho]

but would that still work as the else would happen because var has become 2? The second bit of code musn't execute if the first if statement is true. I could use another variable but I was trying to think of a more efficient way of doing this

BTW, how do u put that code:______ thing in for script?

[chi-styler]

Nope, that will work. Open up a new movie and put this in

myVar = 1;
if(myVar == 1) {
  trace("first");
  myVar = 2;
}else if(myVar == 2) {
  trace("second");
  myVar = 1;
}

That's the whole points of using else, once it enters one bit, it "breaks" itself, not entering anything other bit, whatever you have changed.

(Take a look at vB Code link at top of page)

I would use a switch statement:

switch (var)
{
case 1:
var = 2
this.happen
break

case 2:
var=1
this.happen
break
}
