Java Processing Game over Screen erstellen?

Hey ich habe eine Version von Pong erstellt um mich ein wenig rumzuprobierem. Demnach ist es weder schön noch besonders ausgereift. Ich habe folgendes gecodet und Frage mich wie ich auf Knopfdruck ein neues Spiel starten kann. Ich hab schon was implementiert was aber nicht funktioniert hatt. Vielleicht ist der Ansatz ja auch richtig. Vielen Dank:

int screen = 0;
int end = 0;
float x = 0;
float y = 0;

int xball = 500;
int yball = 500;
int xdir = 1;
int ydir = 1;



void setup(){
  
 fullScreen();
 smooth();
  
}

void draw(){
 background(38,30,38);
 strokeWeight(5);
 stroke(39,255,36);
 fill(39, 181, 36);
 rect(25,(mouseY/25)*25,25,25);
 rect(25,((mouseY/25)*25)+25,25,25);
 rect(25,((mouseY/25)*25)-25,25,25);
 rect(25,((mouseY/25)*25)-50,25,25);
 rect(25,((mouseY/25)*25)+50,25,25);
  
  
 stroke(255,39,36);
 fill(181,39,36);
  
 
  
  
 fill(255,39,36);
 stroke(181,39,36);
 rect((xball/25)*25,(yball/25)*25,25,25);
 xball = xball+xdir*4;
 yball = yball+ydir*2;
  
  
  
  if (xball > width-25){
   xdir = xdir * -1;
  }  
 
 if (xball < 25){
  screen = 1;
 }
 
 if (xball < 75){
  if (xball > 25){
  if (yball > ((mouseY/25)*25)-50){
   if(yball < ((mouseY/25)*25)+50){
   xdir = xdir * -1;
  }}}}
  
  
 if (yball > height-25 || yball < 25){
   ydir = ydir * -1;
  }
   
 if (screen > 0){
  noStroke();
  fill(0);
  rect(0,0,width,height);

 if(mouseX > width/4+100){
  if(mouseX < width/4+600){
   if(mouseY > height/2+260){
    if(mouseY < height/+310){
     if(end > 0){
      screen = -1;
      end = 0;

Javascript Cookie beim neu laden verhindern?

Hallo,

Wie kann ich verhindern, dass der Cookie beim neu Laden der Seite verhindert wird? Denn immer, wenn ich am Anfang den Namen des Besuchers abfrage, wird dieser nicht nur immer beim neuen betreten der Website gezeigt, sondern auch, wenn man die Seite neu lädt. Wie kann ich das verhindern?

Vielen Dank!

Hier mein Code:

<!DOCTYPE html>


<html>
    <head>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    </head>
    <body onload="checkCookie()">
        <input type = "button" onclick = "setCookie('anwender','',-1)" value = "Cookie
        l&ouml;schen">
        <h1>Website Test-Cookie</h1>
        <script>
        function setCookie(cookieName,inhalt,dauer) {
            let datum = new Date();
            datum.setTime(datum.getTime() + (dauer*24*60*60*1000));
            let ablaufdatum = "expires=" + datum.toGMTString();
            document.cookie = cookieName + "=" + inhalt + ";" + ablaufdatum;
        }


        function getCookie(cookieName) {
            cookieName += "=";   
            let decCookie = decodeURIComponent(document.cookie);          
            let arr = decCookie.split(';');
            for(let i = 0; i < arr.length; i++) {
                let inhalt = arr[i];
                while (inhalt.charAt(0) == ' ') {
                    inhalt = inhalt.substring(1);
                }
                if (inhalt.indexOf(cookieName) == 0) {
                    return inhalt.substring(cookieName.length);
                }
            }
            return "";
        }


        function checkCookie() {
            let anwender = getCookie("anwender");
            if (anwender != "") {
                alert("Hallo " + anwender + "!");
                $("h1").hide();
            }
            else {
                anwender = prompt("Geben Sie bitte Ihren Namen ein:");
                $("h1").show();
                if (anwender != "" && anwender != null) {
                    setCookie("anwender", anwender, 180);
                }
            }
        }
        </script>
    </body>

Wieso ändern sich die Position der Elemente am Handy?

Hey Leute,

ich habe ein kleines Preoblem und zwar die Positionen der Elemente im Android Studio enspricht nicht der am Handy also am Handy werden sie komplett anders angeordernt und nicht wie ich sie im Android Studio positioniert hatte.

Z.B. der Button sollte oben sein und nicht unten!

Hat jemand vielleicht eine Idee voran es liegen könnte?

Danke im Voraus
