Here's a snippet

  boolean returnButtonDisappeared = true;
  boolean usernameBoxDisappeared = true;

  //If the previous scene was the menu scene.
  if (previousScene == 3) {
    //The booleans will be set to false if the objects haven't disappeared.
    returnButtonDisappeared = returnButtonDisappear();
    usernameBoxDisappeared = usernameBoxDisappear(); 

    //If either of the objects haven't disappeared keep drawing that object.
    if (!returnButtonDisappeared) returnButton();
    if (!usernameBoxDisappeared) usernameBox();
  }

  //If both the objects have disappeared draw the new objects and make them appear.
  if (usernameBoxDisappeared && returnButtonDisappeared) {
    specialThanksAppear();
    pressHereAppear();

    specialThanks();
    pressHere();

To be specific, I'm making a 2d game with fractal background and I want that background to be drawn once without my other objects leaving a trail behind. I can't have the background change every now and then. Also, some of my objects are player controlled so continuous draw is required.

Any tips/solutions are welcome, ty.

Im new to processing and I cant figure out how to begin my program with a startpage, then when a key is pressed show a different page with a countdown of 10 seconds and a red blinking circle. After 10 seconds you release the key and it shows a message and closes the program.

I got a few things done like it begins at the startpage but the timer already starts running when i run the program, not when the key is pressed. It should begin counting when the key is pressed When i hold a key it does jump to the "holding a key" page. i tried a lot of other methods with a timer but they all failed because the timer doenst start when the key is pressed.

If someone could give me some tips it would be great!

code:

int fadeAmount = 5;
int opacity = 255;
int circleSize = 75;
int circleYpos = 700;
int circleXpos = 700;
int timer;
int count = 10;
int trigger = 0;


void setup() {
  size(800, 800); 
  smooth();
  background(250);
} 

void draw() {

  if (keyPressed == true) {
    circle_on();
  } else if (keyPressed == true || timer > 10000) {
    processing();
  } else {
    startPage();
  }
}

void startPage() {
  fill(0);
  background(250);
  textSize(50);
  text("Start", width/2 - 50, height/2);
}

void circle_on() {

  background(250);
  fill(255, 2, 2, opacity);
  noStroke();
  ellipse(circleXpos, circleYpos, circleSize, circleSize);
  if ((opacity ==0) || (opacity ==255))  
    fadeAmount = -fadeAmount;

  opacity += fadeAmount;

  fill(0);
  textSize(50);
  text("Are you sure?", 200, 720);
}



void processing() {
  background(250);
  fill(0);
  textSize(50);
  text("Agreement success.", 150, 720);
  fill(250);
  noStroke();
  ellipse(circleXpos, circleYpos, circleSize, circleSize);
}

void keyPressed() {
  timer = millis();

}

Player p;

void setup(){
  //initializes the sketch
}
void draw(){
  p.say("Hi!",1000,2500)//Hi!
  p.say("i come after mousePressed",x,y)//Here comes the problem!
}
//end

I tried playing with millis-int thingie but the problem is that the variable changes per frame. Please help me.

I am just wondering below code, a simple one:

void setup() {
  size(200,200);
  background(0);
}

void draw() {
  fill(255);
  text("hi",80,80);
  delay(1000);
  text("hi2",80,80);
  background(0);
  text("hi3",80,80);
}

My thought is that the window will show "hi", then wait for 1 second, show "hi2", clean up, then "hi3". However, what i see is: keep showing "hi3". What's more strange is that, when i go into debugger mode step by step, I find "hi" is not showing up at all! So i get confused if, within the draw() loop, there is precedence of these regular functions? Thanks to all!

NEXT I want a new random location for the bomb. I don't know where I am going wrong. I am trying to make this more efficient by using function for each thing that I am doing. I am sure there is something major wrong here, but I just can't make heads of tails of it right now . I don't know how to attach the two images.

I also had to make up my own TIME DELAY because I can't figure out how to do it.

start_drop=0

def setup():
    global img, img2, random_start_x
    size(400, 400)
    background(255) # white
    img=loadImage("bombsmall.jpg")
    img2=loadImage("explosion.jpg")
    random_start_x=int(random(1,400))    

def draw():
    global img, img2
    random_start()

def random_start():
    random_start_x=int(random(1,400))    
    print("This is the new start on x ", random_start_x)     
    bomb()

def bomb():
    global start_drop, img, img2, random_start_x
    background(255)
    image(img, random_start_x, start_drop)
    start_drop=start_drop+5
    if start_drop>360:
        c=0
        while c<1000:
           explosion()
           print(c)
           c=c+1
        start_drop=0
        random_start()

def explosion():
       global img2
       print("test")
       img2=loadImage("explosion.jpg")
       image(img2, random_start_x, 100)

I am making a "game box". I have a simple main menu where i want to access my 2 processing games from. I am using keys for this, so if(keyPressed) { if (key =='1') { stage = 1; if '2' is pressed then stage = 2, same with stage 3. Problem is that when i press '2', i move to stage 2, but when i press 1 or 3, nothing happens. I've tried printing the stage to the console and it writes 1 when i start it up, but when i go to either stage 2 or 3 prints once and then it stops.

Here's a bit (starts in stage 1 defined in setup): if(keyPressed) { if (key == '1') { stage = 1; } if (key == '2') { stage = 2; } if (key == '3') { stage = 3; } }

if (stage == 2){ background(255,0,0); //red Game1 code is supposed to go here println(stage);

if(keyPressed) { if (key == '1') { stage = 1; } if (key == '2') { stage = 2; } if (key == '3') { stage = 3; } } } if (stage == 3){ background(0,255,0); //green Game2 code is supposed to go here println(stage);

if(keyPressed) { if (key == '1') { stage = 1; } if (key == '2') { stage = 2; } if (key == '3') { stage = 3; } } }

The program continues and before the scan finishes and puts a file in the directory I use to put up image, it gets to the load file statement and can't find it , it's not there yet.

I am trying to use this code to test the file exists before letting the program continue but it complains "unexpected token boolean"

boolean fileExists(String "test.png")

File file = new File("test.png");

while(!file.exists());

Am I on the right tract?

Here's what happens, I "shoot" with LMB, bullet shoots, hits target and there should be an explosion, but no explosion happens. The explosion only happens if I press the "shoot" (LMB) button again.

What can I do to make the explosion explode as it should?

Second half of the code

edit: my code gets extremely bugged if i post it as a code(wtf) so ill try as a quote
