how to do inetarcction

ppp

I was wrong code, I pass the right, I can not find it, nose if I deleted it

ppp

Another way to write that? baladx = map(mouseX, 0, width, -10, 10);

ppp

LETS DO BY PARTS

FIRST OF ALL, WHY DON'T WORK, I PUT THE 2 ARRAYS, BUT DON'T WORKS, I DON'T WRITE NOTHING ABOUT THE COLLISION

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();
    }    
      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);
        }
      }
    }
  }
}

ppp

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

     else()
     choque= false;
