    makes me realize I don't understand null-safety with passing functions

    obviously that middle part is not complete, but the idea is to apply an or function to the setColor

    Maybe I could just write an extension function instead

    amanda, what the issue is, that the foo is a function
  • h

    Hamza

    09/11/2018, 3:28 AM
    you need to provide the paramater a color
  • h

    Hamza

    09/11/2018, 3:28 AM
    you need to actually provide a writable image to foo, so it returns a color
  • h

    Hamza

    imagine you have a function, which takes x, and returns x + 1. it returns an integer. if you just provide the function, it wont be able to know what number you are providing to it

    instead of 
    pixelWriter.setColor(i, j, foo)
    , you need to have 
    pixelWriter.setColor(i, j, foo(someWritableImage))
    💯 1
  • h

    Hamza

    09/11/2018, 3:30 AM
    to invoke foo
  • h

    Hamza

    09/11/2018, 3:30 AM
