Haven't you already posted the same thing in your 1st thread? :-$

yeah but i don't understand the flappy bird concept

mikw123

im a beginner at processing

DCRaven

This is the smallest flappy bird code(when minified) made in processing at this moment (made by me. It will soon be crushed i'm sure). Read the //comments very carefully as I've tried to explain it as well as I can:

//sets up the variables for the pipe and bird positions and score:
float p=400, a;
int g, s, v=166, w=500, z=200;
boolean d, f, t;
float[]y= {
  z, w, v
};
void setup() {
  //sets up the sketch
  size(w, 800);
  strokeWeight(3);
  textSize(25);
}
void draw() {
  //clears the display
  clear();
  if (d&&f) {
    //if you are not dead then move the pipes
    int x=w-frameCount*2%v;
    if (x==w) {
      y[0]=y[1];
      y[1]=y[2];
      y[2]=random(w);
    };
    //set the gravity:
    a+=.3;
    //draw the pipes:
    rect(x-v, -5, v, 805);
    rect(x-332, 0, 0, 800);
    stroke(0);
    int c=3;
    //draw the gap in the pipes
    for (int i=x;i>x-333;i-=v)line(i, y[c-=1], i, y[c]+z);
    stroke(255);
    //test for the pipes colour:
    d=get(100, int(p=max(min(p+a, 795), 5)))==color(0);
    //adds your score if you have just gone through a pipe
    if (d&&x==400)s++;
    //draw the player and your score:
    ellipse(100, p, 20, 20);
    r(0, 0, str(s));
  }
  else {
    //else if you are dead then display 'game over' and your score
    r(v, 300, (f?"game over":"flappy bird"));
    //if its your first time playing the game then it will have a title screen with 'flappy bird' 'click to play'
    r(v, w, (f?"score:"+s:"click to play"));
  }
  //If you press a button or the mouse then run function 'c'
  if (mousePressed||keyPressed)c();
}
void c() {
  //set the acceleration and score:
  if (!d)s=0;
  a=-7;
  d=f=!t;
}
void r(int x, int y, String s) {
  //draw the box with the text:
  stroke(255);
  rect(x, y, z, 40);
  fill(255);
  text(s, x+30, y+30);
  fill(0);
}

Does that help?

thankyou

mikw123

also quick question how to i get the fish to move up and down using the arrow buttons?

PhiLho

Your fish has probably a variable telling the vertical position where to draw it. If not, create such variable!

Then, on keyPressed(), detect if it is an arrow key, and if so, change the value of the vertical position.

Beside, collision check and scoring are among the most asked topics in this forum, and are shown in lot of examples. Some search can help.

Oh, and avoid to make duplicate threads. A simple additional question in the original thread would have been enough.

how do i create bubbles using loop?

Chrisir

here collision check

void collisionFish() {

  // collision check  
  boolean isWater; 

  // if near the wall area 
  if (x>455) {
    //  
    // is water or wall before the fish? 
    isWater = get ( x+26, y ) == color (70, 190, 199);
    if (isWater) {
      if (x>470) { 
        score++;
        // restart Fish
        restartFish();
      }
    }
    else 
    {
      // collision
      if (x>455) { 
        score--;
        // restart Fish
        restartFish();
      }
    } // else
  } // if
} // func 

Chrisir

I did bubbles in one of the other threads for fish from your class.

google it

• you have to change it though because you're number 3 using it, so I mustn't look like plagiarism

@Chrisir, no use to keep helping him!
@mikw123 is erasing everything and asking about "deactivating" his account! [-(

Chrisir

he even sent me PMs .....

Don't do that (renaming your thread, removing the content of the question. If you don't want to leave traces on Internet, just don't use it.

mikw123

im sorry

Chrisir

to stop the fish from starting automatically again, you need to change restartFish()

don't set x to zero here

Chrisir

or display a text "Click mouse to play again"

mikw123

im still confused

Chrisir

why?

you see the function void restartFish() {

?

Here is a line x=-70; or so

delete this line

Chrisir

or delete the complete function

void restartFish() {
  // restart Fish
  x=-70;
  y=int(random(70, height-70));
  lengthY = int (random(10, height-120));
} // func 

and delete the line where it's called:

restartFish();

Chrisir

I also made one version where the gap in the wall has a new position every time the fish goes through it

mikw123

when I get rid of the void restartFish function, when the fish passes through the gap the score continues to rise

Chrisir

you can have a global var

boolean scorePauses = false;

once the fish is through the score gets higher

set

scorePauses = true; 

after that

then when the mouse is clicked, and a new fish starts say

scorePauses = false;

of course

mikw123

thankyou
