how to have all of the platforms stay visible?

```auto

float charx=0;

  background(shrek);

  platform.display();
  
  image(soldier[i], charx, chary, 100, 100);

  //timer
  println(millis()/1000);
  if (millis()/1000%300==0&&millis()/1000>10&& invert==false) {
    invert=true;

    invert=false;
  }
  if (invert==true) {
    filter(INVERT);
  }

  //moving
  if (charx>=width-100) {
    charx=width-100;
  }
  
  jumpspeed= int(dist(0, jumpingheight, 0, chary)/20);

  if (chary>height-100) {
    chary=height-100;
  }
  if (keyPressed) {

    //move left with a
    if (key == 'a'&&invert==false) {

      jumping=false;
    }
  }
  if (chary!=height-100&&jumping==false) {
    chary+=gravity;
  }
  println(chary);

```

```auto

it’s easier when you define it in setup()

and in draw() just display the platforms

```auto

//visual
PImage shrek;
boolean invert= false;
PImage[] soldier= new PImage[3];
Platform platform;

//moving
float charx=0;
float chary=563-100;
boolean jumping= false;
float gravity= 10;
float jumpingheight=100;
float jumpspeed;
int i=1;

//---------------------------------------------------------------------------------------

void setup() {
  size(1000, 563);
  shrek= loadImage("shrek.jpg");
  soldier[1]= loadImage("soldier.png");
  soldier[2]= loadImage("revsoldier.png");

  platform= new Platform(random(10, 200), random(10, 200));
}

void draw() {

  frameRate(60);
  //visual
  background(0);
  color(1005);

  platform.display();

  text("soldier[i]", 
    charx, chary, 100, 100);

  //timer
  println(millis()/1000);
  if (millis()/1000%300==0&&millis()/1000>10&& invert==false) {
    invert=true;
  }
  if (millis()/1000%600==0&&millis()/1000>10&& invert==true) {
    invert=false;
  }
  if (invert==true) {
    filter(INVERT);
  }

  //moving
  if (charx>=width-100) {
    charx=width-100;
  }

  jumpspeed= int(dist(0, jumpingheight, 0, chary)/20);

  if (chary>height-100) {
    chary=height-100;
  }
  if (keyPressed) {

    //move left with a
    if (key == 'a'&&invert==false) {
      charx=charx-10;
      i=2;
    } 

    //move right with d
    if (key == 'd'&&invert==false) {
      charx=charx+10;
      i=1;
    }

More distance between platforms, still a bit random in y-direction

```auto

  Platform platform;
  for (int i=0; i<4; i++) {

    prevYValue = yValueForRandom; 

    platform = new Platform(random(10, 400), yValueForRandom);
    platforms.add(platform);
