SNEX UI Parameters

[A Former User]

@Straticah

idk what's going on with this example, but to get SNEX parameters working:

click the 3 dots -> "Add Parameter", give it a name and range of values, then in the SNEX script

//declare a variable the parameter will control
float myVar = 0.0; 

template <int P> void setParameter(double v)
{
	if (P ==0) // the index of our parameter
	{
		myVar = v;
	}
}

you can inspect the variable changing by opening the data table (eye icon)

@Straticah I‘m afraid you need a basic understanding of C++ in order to write C++ code :)

In your example you‘re redeclaring a variable within the same scope.

@Christoph-Hart Which variable is redeclared? I don't see it? He has scopes around each parameter.

@Christoph-Hart

But this is legal:

{
    // scope a
    int p = 42;
    // ...
}
{
    // scope b
    int p = 43;
    // ...
}

[Christoph Hart]

@tobante Yes but this isn't:

int p = 41;
{

}
int p = 42;

[tobante]

@Christoph-Hart I'm still confused.

• Function: L59 -L75 (contains 2 nested scopes)
• Scope A: L60 -L65 (contains 1st p)
• Scope B: L68 -L74 (contains 2nd p)

Indentation is a little misleading, but it is valid.

[tobante]

@Christoph-Hart I agree that your example is invalid, but that's not what @Straticah has in his example. The error probably is that he uses d for the parameter he called data. Not sure why the compiler flags line 58. Maybe it's always beginning of function.

[Christoph Hart]

haha, now I see it too. That is a contender for worst code formatting ever...

[tobante]

@Christoph-Hart I was so confused, because I gave @Straticah the code from your GitHub repo. :)
