Making a Game "Launcher"

Processing Coding Questions
1

Is there any way to make something like a “launcher” in processing. What I mean by that is basically a main menu and when you click a button, it closes itself and opens another .exe file (or runs a processing source code which would be better).

You can try using launch() or exec(). I have attached other posts that are relevant.

Thanks! I’ll take a look.

Thanks again!
The solution here worked:

I made it so it launches when I click a button but it launches my application 2-5 times depending on how long the mouse stays on the button after clicking. It looks like it is a problem with my button. Here is my full code:

//PFont zigBlack;
int b1f = 140;
int b2f = 140;
int b3f = 140;
int b4f = 140;
int v1f = 200;
boolean versions = false;
boolean credits = false;
boolean controls = false;


void setup() {
  size(1200,600);
  //zigBlack = createFont("Minecraftia 2.0", 32);
  //textFont(zigBlack);
  frameRate(60);
  smooth();
}

void draw() {
  background(217,125,4);
  fill(0,140);
  rect(35,0,320,600);
  fill(255);
  textSize(45);
  text("The",400,105);
  text("Dungeons",400,160);
  text("Of The West",400,220);
  textSize(15);
  text("tDotW Launcher 1.0",1020,600);
  fill(0,b1f);
  rect(400,225,350,70);
  fill(0,b2f);
  rect(400,315,350,70);
  fill(0,b3f);
  rect(400,405,350,70);
  fill(0,b4f);
  rect(400,495,350,70);
  fill(255);
  textSize(25);
  text("Launch Game",420,286);
  text("Controls",420,376);
  text("Credits",420,466);
  text("Quit Launcher",420,556);
  
  if (versions == true) {
    fill(0,140);
    rect(800,0,360,600);
    fill(0,200);
    rect(800,0,360,30);
    
    fill(0,v1f);
    rect(800,45,360,100);
    
    fill(255);
    textSize(25);
    text("Version 1.0",810,93);
    textSize(15);
    text("Release Date: N/A",810,110);
    
    fill(255);
    textSize(15);
    text("Select a version",808,32);
  }
  
  if (controls == true) {
    fill(0,140);
    rect(800,0,360,600);
    fill(0,200);
    rect(800,0,360,30);
    fill(255);
    textSize(15);
    text("Controls",808,32);
  }
  
  if (credits == true) {
    fill(0,140);
    rect(800,0,360,600);
    fill(0,200);
    rect(800,0,360,30);
    fill(255);
    textSize(15);
    text("Credits",808,32);
  }
  
  if(mousePressed && mouseX>800 && mouseX<1160 && mouseY>45 && mouseY<145) {
    PrintWriter output=null;
    output = createWriter("myfile.bat");
    output.println("cd C:/Users/Lenovo/Desktop/Dungeon_Game/application.windows64/");
    output.println("start  Dungeon_Game.exe");
    output.flush();
    output.close();  
    output=null;
    launch(sketchPath("")+"myfile.bat");
}
  if(versions == true && mouseX>800 && mouseX<1160 && mouseY>45 && mouseY<145) {
    v1f = 140;
  } else{
    v1f = 200;
  }
  
  if(mousePressed && mouseX>400 && mouseX<750 && mouseY>225 && mouseY<295) versions = true;

    credits = false;
  }
  
  if(mouseX>400 && mouseX<750 && mouseY>315 && mouseY<385) {
    b2f = 200;
  } else{
    b2f = 140;
  }
  
  if(mousePressed && mouseX>400 && mouseX<750 && mouseY>405 && mouseY<475) credits = true;
  if(mousePressed && mouseX>400 && mouseX<750 && mouseY>405 && mouseY<475 && versions == true) {
    credits = true;
    versions = false;
  }
  if(mousePressed && mouseX>400 && mouseX<750 && mouseY>405 && mouseY<475 && controls == true) {
    credits = true;
    controls = false;
  }
  
  if(mouseX>400 && mouseX<750 && mouseY>405 && mouseY<475) {
    b3f = 200;
  } else{
    b3f = 140;
  }

  if(mousePressed && mouseX>400 && mouseX<750 && mouseY>495 && mouseY<565) exit();
  
  if(mouseX>400 && mouseX<750 && mouseY>495 && mouseY<565) {
    b4f = 200;
  } else{
    b4f = 140;
  }
  
}

The “Version 1.0” button launches it (it appears when clicked on “Launch Game”). How can I fix this?

EDIT: Fixed it, my dumbness. Instead of if(mousePressed &&), I created a mouseClicked() void and put the stuff under that.
