Help with Stripe Plugin

As long as you are using CodeLab v3.0 (or higher), you can.

 

Please, make a codelab tutorial part 7/8/9 ( whichever number is correct.) It's an important feature and users should be aware of this.

[BoltBait]

Once I publish the next release of CodeLab (which should be in the next day or so), I will revisit all of my tutorials.  I've already rewritten #7.  But, I'll start at the beginning and do them all over again.

I don't understand what is happening here, I want declare a method  and call it. How to make it work?

Don't declare types in the call.

 

Change:

sf1 = SmoothingFactor(int k, int stepR);

to:

sf1 = SmoothingFactor(k, stepR);

    ColorBgra PC = Amount3;
    ColorBgra SC = Amount4;

    //Invert color in plugin
    if ( Amount5 == true)
    {
        ColorBgra k = PC;
        PC = SC;
        SC = k;
    } 

Tidier... (edited thanks to MadJik's tip)

    ColorBgra PC, SC;
    
    //reverse colors if Amount5 is true
    if (Amount5) // you can optionally omit "== true" here
    {
       PC = Amount4;
       SC = Amount3; 
    }
    else
    { 
       PC = Amount3;
       SC = Amount4;
    }

 

[MadJik]

PC and SC must be defined before the  if...

I really should check my code before posting

 

Edit: fixed.
