Simple Question Time - Printing a String to the screen?

string test;
integer col = 1;

if(col == 1) {string test = "Hello";}

llOwnerSay( test );


Does not error on compilation, but obviously something wrong here, and can't find out the simple answer to this.

Looked here:

and

But does not really help me.

I know it's a simple basic thing, but kinda stuck with the syntax needed here.

You have declared the 'string test' twice.

Try this:

string test;
integer col = 1;

if(col == 1) {test = "Hello";}

llOwnerSay( test );

You've defined "test" twice .... once in your first line and again in the if statement. I'm surprised the compiler didn't spit up. As for why it didn't say anything, my guess is that there's something in the parts of the script that you didn't show here that either bypasses the if test or reloads "test" with the value " ".

It's also possible that something in parts of the script that you didn't show us is either bypassing the if test or is reloading the variable "test" with the value " ".

Thanks, that was exactly the problem

I didn't realise that once you have declared (in this instance) "test" as the string, that you could just use it's name on it's own.

Again, (give me a slap) in Basic, I'm used to having to refer to it as a string each time as in.

A$="hello"

So each time you used the string you have to use the $ symbol.

I suppose (now I know) as you have at the start identified it as a string, from then on the scrip knows it's a string.

Logical, but just not what I was used to

Thanks for the suggestion, it was just as I was declaring the string more than once which was screwing it.

Another tiny hurdle overcome

Not quite true. It not a matter of defining it "at the start." It has to be defined within the scope where you are using it. Compare .....

string test;
default{
     state_entry{
          test = "Hello!";
     }
     touch_start(integer num){
          llSay(0, test);
     }
}

with .....

default{
     state_entry{
          string test = "Hello!";
     }
     touch_start (integer num){
          string test;
          llSay(0, test);
     }
}

In the first case, "test" is defined globally -- its scope is the entire script, so you can give it a value in one event and use it in another. In the second case, "test" is defined separately in each event. It's actually a different variable. Loading it with "Hello!" in state_entry has no effect when you try to llSay it in touch_start. In THAT scope, "test" has its default value, " ".
