How should I properly initialize char variables?
My code:

String randomPlanetName(){
  String name = "";
  int dimension = int(random(3,12));
  
  int repetitions = 0;
  boolean lastType;
  for(int i = 0;i == dimension;i++){
    boolean type = boolean(int(random(0,1)));
    char selection;
    if(repetitions < 2){
      type = !type;
    }
    if(type == true){
      if(i == 0){
        selection = upperCaseVowels[int(random(0,upperCaseVowels.length - 1))];
      }else{
        selection = lowerCaseVowels[int(random(0,lowerCaseVowels.length - 1))];
      }
    }
    if(type == false){
      if(i == 0){
        selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length - 1))];
      }else{
        selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length - 1))];
      }
    }
    name += selection;
    lastType = type;
    if(lastType == type){
      repetitions++;
    }else{
      repetitions = 0;
    }
  }
  return name;
}

Error: The local variable "selection" may not have been initialized

Thanks for reading, and thanks for answering!

if(type == true){ -> if (type) {

if(type == false){ -> else {

Thanks! It worked! :smiling_face_with_three_hearts:

I’m suspicious that variable type won’t ever be assigned true outta that expression. :thinking:

You can do something like this instead: :bulb:
final boolean type = random(2) < 1;

Yeah, I also noticed that this function never work…

boolean type = round(random(0,2)) == 1;

this is probably always false

No, it’s random true or false
(Oops, looks like I put the wrong code into it)

It don’t work even after changing the code…
Logic Error.

or

type=false; 
if(random(1)<0.5) 
     type=true;

No, I don’t mean the random boolean, I mean the code.

void setup(){
  
}

void draw(){
  println(randomPlanetName());
}

char[] upperCaseVowels = {
  'A',
  'E',
  'I',
  'O',
  'U',
};

char[] lowerCaseVowels = {
  'a',
  'e',
  'i',
  'o',
  'u',
};

char[] upperCaseConsonants = {
  'B',
  'C',
  'D',
  'F',
  'G',
  'H',
  'J',
  'K',
  'L',
  'M',
  'N',
  'P',
  'Q',
  'R',
  'S',
  'T',
  'V',
  'W',
  'X',
  'Y',
  'Z',
};

char[] lowerCaseConsonants = {
  'b',
  'c',
  'd',
  'f',
  'g',
  'h',
  'j',
  'k',
  'l',

  'p',
  'q',
  'r',
  's',
  't',
  'v',
  'w',
  'x',
  'y',
  'z',
};

char[] numbers = {
  '0',
  '1',
  '2',
  '3',
  '4',
  '5',
  '6',
  '7',
  '8',
  '9',
};

char seperator = ' ';

String randomPlanetName(){
  String name = "";
  int dimension = int(random(3,12));
  
  int repetitions = 0;
  boolean lastType;
  for(int i = 0;i == dimension;i++){
    boolean type = round(random(0,2)) == 1;
    char selection;
    if(repetitions > 2){
      type = !type;
    }
    if(type){
      if(i == 0){
        selection = upperCaseVowels[int(random(0,upperCaseVowels.length))];
      }else{
        selection = lowerCaseVowels[int(random(0,lowerCaseVowels.length))];
      }
    }else{
      if(i == 0){
        selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length))];
      }else{
        selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length))];
      }
    }
    name += selection;
    lastType = type;
    if(lastType == type){
      repetitions++;
    }else{
      repetitions = 0;
    }
  }
  return name;
}

The name returned will always be "".

An alternative (and very interesting) way to shift upper to lower case (and vice-versa) ASCII letters: :nerd_face:

char letter = 'E';
println(letter); // E

char lower = (char) (letter | ' '); // e
println(lower);

char upper = (char) (lower & ~' '); // E
println(upper);

exit();

Alright.

String randomPlanetName(){
  String name = "";
  int dimension = int(random(3,12));
  
  int repetitions = 0;////////////////////////////////////////////////////////////// variable for repetition count
  boolean lastType;
  for(int i = 0;i < dimension;i++){
    boolean type = round(random(0,2)) == 1;
    char selection;
    if(repetitions > 2){
      type = !type;///////////////////////////////////////////////////////////////// if repetitions is more than two, reverse the vowel consonant
    }
    if(type){
      if(i == 0){
        selection = upperCaseVowels[int(random(0,upperCaseVowels.length))];
      }else{
        selection = lowerCaseVowels[int(random(0,lowerCaseVowels.length))];
      }
    }else{
      if(i == 0){
        selection = upperCaseConsonants[int(random(0,upperCaseConsonants.length))];
      }else{
        selection = lowerCaseConsonants[int(random(0,lowerCaseConsonants.length))];
      }
    }
    name += selection;
    lastType = type;//////////////////////////////////////////////////////////////// for easiness we use type to say vowel or consonant
    if(lastType == type){
      repetitions++;//////////////////////////////////////////////////////////////// if the last type is equal to this type
    }else{////////////////////////////////////////////////////////////////////////// then change repetition count by 1
      repetitions = 0;////////////////////////////////////////////////////////////// or else set it to 0
    }
  }
  return name;
}

For example, I want to have a name like “Chareturn” and not “Fleaiiiiiaoster”.

A funny name I generated from my generator: “Ieeoiiaea”

so you mean : avoid the repetition of a vowel OR a consonant

so earth, Saturn and moon not allowed
