I know it's a very basic question, but here it is anyway.
I need to pass a string as an argument to a script function and compare that argument inside the function. I'm registering a type with RegisterStdString();
Am I suppposed to use setArgObj(..) to pass the string, and how my script function should be declared in order this to work ?
Can I use something like this ?

//script function
void CompareStr(string& str)
{
if(str == "foo")
{
//do something
}

}


Am I on the right track here, or I'm just doing it wrong ?
Thanks for your time.

You'd probably want to use an input reference (string & in str) rather than an unsafe reference (string & str), but you seem on the right track.

Thanks.
I'm asking, because I'm getting a compile error, stating :

ERR : No matching operator that takes the types 'string&' and 'string&' found.

And then

ERR : Expression must be of boolean type.

When I try to compare the strings in the script like so :
void CompareStr(string ∈ str)
{
if(str == "test") {}
}

What I need to do in order to use operators on strings ?

You shouldn't have to do anything special. The == operator is supported through the opEquals method registered for the string type by RegisterStdString.

I just tested this to make sure it works and didn't have any trouble with the latest version. What version of AngelScript are you using?





If the function takes the string by reference, you should use asIScriptContext::SetArgAddress to pass the address of the string to the function.

Thank you for the answer.
I'm using version "2.16.0" and just pasted the


just before building of the module and that failed too with the same messages.
Probably I need to upgrade to the latest version. Will keep you in touch. [smile]

Despite of the warning that it has problems, I just upgraded to the latest "2.20.1" version and all is working just fine!
Thanks again.
