How to do an interaction 2

ppp

its a shotter game you shhoot bala (bullet) and kill soldat (soldier)

ArrayList bales; Bala bala1; PImage img;

void setup() {
  size(800, 450);
  stroke(255);
  fill(255, 255, 255);
  bales = new ArrayList();
  bala1 = new Bala();
  img = loadImage("pa.jpg");
  bales.add( bala1 );
}

void draw() {
  image(img, 0, 0);

  line(400, 450, mouseX, 2 * mouseY);
  strokeWeight(mouseY/10);


  for ( int i = 0; i < bales.size(); i++) {
    bala1  = (Bala)bales.get(i);
    bala1.balesmoviment();
  }
}

class Bala {
  float balapx, balapy;
  float baladx, balady;
  Bala() {//creamos una bala
    balapx = width/2.0;
    balapy = height;
    baladx = map(mouseX, 0, width, -10, 10);
    balady = -10;
  }

  void balesmoviment() {
    balapx += baladx;
    balapy += balady;
    ellipse( balapx, balapy, 2, 2);
  }
}


void mousePressed() {
  if ( bales.size() > 9 ) bales.remove(0);
  bales.add( new Bala() );
}
{
  ArrayList soldats;
  Soldat soldat1;
  {

    void setup() {
      soldats= new ArrayList();
      soldat1 = new Soldat();
      soldats.add (soldat1);
    }
    void draw() {
      for ( int i = 0; i < bales.size(); i++) {
        soldat1  = (Soldat)soldats.get(i);
        soldat1.soldatsmoviment();
      }


      boolean choque( float balaX, float balaY, float balaR, float soldatX, float soldatY, float soldatW, float soldatH ) {
        if (balaX==soldatX)&&(balaY==soldatY)&&(balaR==(soldatW*soldatH)) {//collision of 2 bullets
          choque=true;

          else() {
            choque= false;
          }
        }

        class Soldat { // Here the problem, how to make rectangles that move and avance in the map
          float soldatpx, soldatpy;
          float i;
          Soldat() {//creamos unsoldat
            soldatpx = width+i;
            soldatpy = 0;
          }
          void soldatsmoviment() {
            soldatpx +=i;

            rect( soldatpx, balapy, 10, 20);
          }
        }
      }
    }
  }
}

still not finished, i see...

Sigh. I said I was done. But I can still run your mess of code through the cleaner without doing your collision function for you. So look at this:

// ----- Global Variables -----

ArrayList<Bala> bales = new ArrayList();
ArrayList<Soldat> soldats = new ArrayList();
//PImage img;




// ----- Main Sketch Functions -----

void setup() {
  size(800, 450);
  stroke(255);
  fill(255, 255, 255);
  bales = new ArrayList();
  //img = loadImage("pa.jpg");
  // Create initital Soldats
  for( int i = 0; i < 10; i++){
    soldats.add( new Soldat( random(width-40), -30*i ) );
  }
}

void draw() {
  background(128); 
  //image(img, 0, 0);
  stroke(255);
  line(width/2.0, height, mouseX, mouseY);
  // Remove old Bales.
  for( int i = bales.size()-1; i >= 0; i--){
    if( bales.get(i).px < -20 || bales.get(i).px > width + 20 || bales.get(i).py < -20 ) {
      bales.remove(i);
    }
  }
  // Remove old Soldats
  for( int i = soldats.size()-1; i >= 0; i--){
    if( soldats.get(i).py > height ){
      soldats.remove(i);
    }
  }
  // Create new Soldats.
  while(soldats.size() < 10){
    soldats.add( new Soldat( random(width-40), -30 ) );
  }
  // Move and show all Soldats.
  for ( Soldat s : soldats ) {
    s.move();
    s.show();
  }
  // Move and show all Bales.
  for ( Bala b : bales ) {
    b.move();
    b.show();
  }  
  // Look for collisions.
  for ( int i = bales.size()-1; i >= 0; i-- ) {
    Bala b = bales.get(i);
    for ( int j = soldats.size()-1; j >= 0; j-- ) {
      Soldat s = soldats.get(j);
      if ( choque( b.px, b.py, b.r, s.px, s.py, s.w, s.h ) ){
        // TODO: Make things happen when there is a collision. You should write this!
        /// ...?



      }
    }
  }
}

void mousePressed() {
  bales.add( new Bala() );
}




// ----- Collision Check Function -----

boolean choque( float balaX, float balaY, float balaR, float soldatX, float soldatY, float soldatW, float soldatH ){
  // TODO: Fix this. You should write this function!
  /// ...?



  return( false ); // Placeholder - should not always return false!
}




// ----- Bala Class -----

class Bala {
  float px, py;
  float vx, vy;
  float r;
  Bala() {
    px = width/2.0;
    py = height;
    PVector pv = new PVector(mouseX - px, mouseY - py);
    pv.normalize();
    vx = 5 * pv.x;
    vy = 5 * pv.y;
    r = 10;
  }
  void move() {
    px += vx;
    py += vy;
  }
  void show() {
    fill(255);
    noStroke();
    ellipse( px, py, r, r);
  }
}




// ----- Soldat Class -----

class Soldat {
  float px, py;
  float w, h;
  Soldat(float ipx, float ipy) {
    px = ipx;
    py = ipy;
    w = 40;
    h = 30;
  }
  void move() {
    py++;
  }
  void show() {
    fill(200, 0, 0);
    stroke(0);
    rect(px, py, w, h);
  }
}

This is missing two things. First, the body of the collision function. To fill it in, check out this link:

http://www.jeffreythompson.org/collision-detection/circle-rect.php

Second, it is missing what should happen when there is a collision. Maybe you remove the Soldat s and make the Bala b bounce? Or remove it too? Whatever. That's up to you.

I also commented out your background image because I don't have the image. Leave this commented out so it is easier for us to help you.

ppp

for ( Bala b : bales ) {

this function? ok

ppp

ppp

this is the image

TfGuy44

for ( Bala b : bales ) {

this function? ok

What are you asking? What function? That's a loop. It loops over each Bala in the bales ArrayList.

Your image is not the issue here. How are you getting along with the collisions?

ppp

yesyes

ppp

i'm doing, you will hallucinate

ppp

what it means this loop?

  for( int i = bales.size()-1; i >= 0; i--){
    if( bales.get(i).px < -20 || bales.get(i).px > width + 20 || bales.get(i).py < -20 ) {
      bales.remove(i);

jugar is play

TfGuy44

Alright. One note: The loops on line 95 to 102 aren't doing anything, and can be removed. You have your collision checking elsewhere now.

ppp

and why don' t do the void joc? when I click on play

  image (pantinici, -10, -80);
  if (mousePressed  && (mouseButton==LEFT)) {
    if (mouseX >=370 && mouseX <=400 && mouseY >=440  && mouseY <= 420) {
      estat = 1;
      println("posX");
    }
  }

ppp

  if (estat==0) {
    pantinici();
  }   
  if (estat==1) {
    joc();
  }
}

//estat= 0;

void pantinici() {

  scale(1);

      estat = 1;
      println("posX");

Sorry,this

ppp

with out print ln

void joc()

TfGuy44

No one, myself included, has any idea what you are talking about. What are you asking? What code is that? Is that a different sketch?

ppp

nono, look at your gmail, execute the code, and you will understand, is the first page of the game when you click on play and the game run

Dinoswarleafs

I personally have accepted ppp as our lord and savior

ppp

what?

ppp

tfguy, is the last question

ppp

Tf Guy, in the email you have the images to understand what I have talk to you

ppp

But where I talk to you? The mail is for you to understan what im doing. When you play a game first there is a first page where put play, you click on play and then the game start. I wanna do this.

ppp

Well, jugar is play, and when i click in the zone of jugar(play), the estat is 1 and then execute void joc (that is the game execute the game.

void draw() {


  if (estat==0) {
    pantinici();
  }   
  if (estat==1) {
    joc();
  }
}

//estat= 0;

void pantinici() {

  scale(1);
  image (pantinici, -10, -80);
  if (mousePressed  && (mouseButton==LEFT)) {
    if (mouseX >=370 && mouseX <=400 && mouseY >=440  && mouseY <= 420) {
      estat = 1;

    }
  }

void joc()

ppp

How I can start a new discussion with this problem? Because this is so long

TfGuy44

Oh, okay, I think I get what you're trying to do. You want a start screen with a play button, and when you click the play button, then the game starts.

So you will need a variable to remember which state your sketch is in.

int state;

Initially, your sketch will be in state #0, the start screen state.

// in setup():
state = 0;

Now in draw(), you will need to either do the start screen (if the state is 0) or run the game (if the state is 1).

// in draw():
if( state == 0 ){
  draw_start_screen();
} else if( state == 1 ){
  run_and_draw_game();
}

Finally, you will need to check if the start button is clicked.

// in mousepressed():
if( state == 0 ){
  if( mouse_on_play_button() ){
    state = 1;
  }
}

If you can explain what you want to do with words first, it is much easier to be able to write the code that does it! Please learn how to describe things better!

ppp

yes, is this, but i do this and don't work

ppp

This was I did, first (if the state is 0) draw pantinici and if estate is 1 execute joc(joc means game) so execute the game. And in the mousePressed, i locate the rectangle of the button Play (300,400,400,420)

void draw() {


  if (estat==0) {
    pantinici();
  }   
  if (estat==1) {
    joc();
  }
}



void pantinici() {

  scale(1);
  image (pantinici, -10, -80);
  if (mousePressed  && (mouseButton==LEFT)) {
    if (mouseX >=370 && mouseX <=400 && mouseY >=440  && mouseY <= 420) {
      estat = 1;

ppp

i Draw the int and nothing, I don't know

ppp

For these reason i pass the images in mail, for you to understan the botton for play(I don't know if I'm doing incorrectly the position of the botton play(in spanish jugar)

TfGuy44

There is a difference between mousePressed (the boolean) and mousePressed() (the function). Use the function.

int state;

void setup(){
  size(200,200);
  state = 0;
}

void draw(){
  if( state == 0 ){
    state0();
  } else if( state == 1 ){
    state1();
  }
}

void state0(){
  background(0);
}

void state1(){
  background(255,0,0);
}

void mousePressed(){
  if( state == 0 ){
    state = 1;
  }
}

ppp

What? but I do this with the exception of the state0 and state1 I write pantinici and joc

ppp

And in the mousePressed I need to to the bolean because the mouse must clik on the button play

TfGuy44

The difference is that my code shows the global state variable, and closes the functions. The code snippet you have posted looks like you grabbed a chunk out of the middle of something.

Please always post complete examples. That way we can copy, paste, and run them easily.

ppp

I do this int state;

void setup(){
  size(200,200);
  state = 0;
}

void draw() {
  if (estat==0) {
    pantinici();
  }   
  if (estat==1) {
    joc();
  }
 // if (estat==2) {
   // game over();
  }
}
void pantinici() {
  scale(1);
  image (pantinici, -10, -80);
  if (mousePressed  && (mouseButton==LEFT)) {
    if (mouseX >=370 && mouseX <=400 && mouseY >=440  && mouseY <= 420) {
      if (estat==0) {
        estat = 1;

Ctrl + t is your friend. It will auto-format your code. That way you can hopefully realize that you are defining your joc() function inside your pantinici() function. You MUST learn to put closing brackets where they belong!

ppp

camon, there is the last question and you will never see me aagain, please help mee

TfGuy44

I've already told you what's wrong. You can fix it.

I don't want to never see you again. I want you to get good at programming and stick around to help other people learn.

ppp

yes, i help my friends an another people

The button and the first image appears, but he don't execute the void game

mouseY >=440  && mouseY <= 420

The mouseY variable can never satisfy both of these conditions at the same time. Any number greater than 440 will never also be less than 420.
