Changing brightness depending on sound (Processing)

问题 I am learning processing right now and I am trying to make a sketch that could change colour when the sound changes. (When Amplitude + , Then Brightness+ ) Because changing colour does not need to change as rapid as the draw() function. So how could I build a clock so that the color would not change in every draw? This is the code I am using right now: import ddf.minim.*; import ddf.minim.signals.*; import ddf.minim.analysis.*; import ddf.minim.effects.*; Minim minim; AudioPlayer song; FFT

What does Void return type mean in Kotlin

问题 I tried to create function without returning value in Kotlin. And I wrote a function like in Java but with Kotlin syntax fun hello(name: String): Void { println("Hello $name"); } And I've got an error Error:A 'return' expression required in a function with a block body ('{...}') After couple of changes I've got working function with nullable Void as return type. But it is not exactly what I need fun hello(name: String): Void? { println("Hello $name"); return null } According to Kotlin

The void type in C

问题 The void type in C seems to be strange from various different situations. Sometimes it behaves like a normal object type, such as int or char , and sometimes it just means nothing (as it should). Look at my snippet. First of all, it seems strange that you can declare a void object, meaning you just declare nothing. Then I created an int variable and casted its result to void , discarding it: If an expression of any other type is evaluated as a void expression, its value or designator is
