First we have to draw rectangles everytime there is a 1 on this array :

  int[][] alienSprite = {
    {1, 0, 1, 1, 1, 0, 1}, 
    {0, 1, 0, 1, 0, 1, 0},
    {1, 1, 1, 1, 1, 1, 1},
    {0, 1, 0, 1, 0, 1, 0},
    {1, 0, 0, 0, 0, 0, 1}
  };

The next thing is to store the position where the invaders will spawn :

  int[] posAlienX = new int[8];

  void setup() { 
    size (800, 600); 
    for (int i = 0; i <posAlienX.length; i++){ 
      posAlienX[i] = x; 
      x = x +100;
    }
  }

Till now it was very basic stuff, i created 2 arrays, one for the rectangles "pattern", one for the invaders positions...

void alien(){

  int spriteY = 20;
  int n = 0;

  for (int s = 0; s < posAlienX.length; s++){
    int spriteX = posAlienX[s];

    while (n < 7) {

      for (int i = 0; i < alienSprite.length; i++ ){

        if (alienSprite[i][n] == 1){
          fill(125);
          rect(spriteX,spriteY,5,5);
          spriteY = spriteY + 5;
        }
        else if (alienSprite[i][n] == 0){
          spriteY = spriteY + 5; 
        }
      }

      spriteX = spriteX +5;

      spriteY = 20;

      n++;
    }
  } 
}

when i enter the loop i want SpriteX to be the position of the cell, but it doesn't work.

Unfortunately it draw only one invader (i need 8). I don't understand because i have a loop to change my SpriteX position with the AlienX array. Again i'm new to Java and programming, so thanks for your help and your patience.

it give me this :

here the code in enemy I think that all you need idk;

class Enemy extends Circle { float life = 1; float spd = 1; float type = 1; // here I give each class a type so I can have several different enemies Enemy(float x, float y, float r) { super(x, y, r); } void show() { fill(128, 0, 128); ellipse(x, y, r*2, r*2); } void move() { x += spd; if (x+r > width && spd > 0) { // here it checks if collide with wall for (Enemy e : enemy) { // here I want it to loop through all the enemy if (e.type == 1 && spd > 0) { //any with type = 1 need to move down spd *= -1; y += 30; } } } else if (x-r < 0 && spd < 0) { /// I havent done this one yet it for the other side spd *= -1; y += 30; } } void grow() { for (int i = enemy.size()-1; i >= 0; i--) { Enemy e = enemy.get(i); if (e.life <= 0) { enemy.remove(i); control.dead -= 1; } } } }

I'm using p5.js.

When the alien is by itself, it moves faster and looks better than in the array. I just change the dx = dx + 5 line. https://www.openprocessing.org/sketch/428281

when I try to change the speed in lines 43 and 53 in the array sketch, it looks terrible.

Thank you,

      }
     }

      if (mousePressed){
        clicked = 1;
      }

      if (clicked == 1){
        xPos = mouseX;

        }
      }
    }

    float ySpeed=50;

    void bulletSpeed(){//functions that adds vertical speed to the bullets
     yPos=yPos-ySpeed;
    }



    void bullet(){//draws bullet
      for(int i=5;i>0;i--){
        noStroke();
        fill(i*50,i*50,255);
        ellipse(xPos,yPos,i*5,i*5);
      }
    }

    void enemies(int xPos, int yPos){//draws eye aliens
      stroke(0);
      fill(255);
      strokeWeight(1);
      ellipse(xPos,yPos,40,40);
      fill(255,0,0);
      ellipse(xPos,yPos,20,20);
      strokeWeight(4);
      point(xPos,yPos);
      stroke(255);
      point(xPos+3,yPos-3);
    }

Sorry about the really bad layout. I'm new to these things.

I'm a NOOB so I barely understand anything.

This is code that I've written:

    }else{
      y=y+random(0.3, 0.5);

    for(Taxi taxi: taxis){
      taxi.x= taxi.x+deltaX;
      if(taxi.x>=600){
        deltaX*= -1;
      }

      if(taxi.x<=0){
        deltaX*= -1;
      }
    }
  return (y<=def1.y);
  }

Currently, the taxis are moving from side to side as I wanted. However, right now I'm running with 2 rows, 5 columns of aliens, for some reason, the change of direction is only activated at the 4th column, meaning the 5th column disappears off screen. This is only occurring on the right side too, so taxi.x<=0 is fine, it seems. The width of the game is 400px as indicated in the setup:

void setup(){
  size(400, 700);
  gameMode=SPLASH;
  reset();
}

Thanks!

If my code is messy, I had to indent it here in the forum to get it onto the forum.

How do I get the Invaders to move down the y-axis?

Now, I'm a noob, so if you say something like: "just inherit a class" or something... that won't help me. Like, I won't know what you mean. Since I'm a noob.

Also when I run my python server, I can't get my blue files to show up in the browser... so when in your browser you have: localhost:8000 and under that you have blue files like:

sketch.js
index.html
main.js
et cetera

I don't have those 4 files. Which ones do I have? None. I have none. It worked before. I'm probably missing a dot or it is some path thing.

Like when you run your python server, have you ever not had the blue files in the browser? If so, what did you do? Perhaps something like localhost:8000 (right, we got that and then perhaps) //some code here(?)

Here is the code below where I don't know how to make the invaders go down the y-axis when it hits the sides.

Also, does anyone know why I can only use one javascript file in my P5 index.html code? If I use two javascript files, only one will work. I use vim and I tried it in text wrangler. Of course neither worked. Has anyone had this problem?

var invaders = [];

   function setup() {
     createCanvas(windowWidth, windowHeight);
     colorMode(HSB);
     for (var i = 0; i < 10; i++) {
     invaders[i] = new Invader(i * 60, 50);
     }
   }

  function draw() {
     background(60, 100, 100);

   var edge = false;
   for (var i = 0; i < invaders.length; i++) {
   invaders[i].display();
    invaders[i].move();
    if (invaders[i].x > width || invaders[i].x < 0) {
    edge = true;
    }
  }

  if (edge) {
    for (var i = 0; i < invaders.length; i++) {
      invaders[i].shiftDown();
    }
  }
}

function Invader(x, y) {
  this.x = x;
  this.y = y;
  this.xdir = 3;
  this.diameter = 50;
  this.display = function() {
    strokeWeight(2);
    stroke(0, 100, 100);
    noFill();
    ellipse(this.x, this.y, this.diameter, this.diameter);
    ellipse(this.x, this.y * 2.2, this.diameter, this.diameter);
    ellipse(this.x, this.y * 3.4, this.diameter, this.diameter);
    ellipse(this.x, this.y * 4.6, this.diameter, this.diameter);
    ellipse(this.x, this.y * 5.8, this.diameter, this.diameter);

  }

  this.shiftDown = function() {
    this.xdir *= -1;
    this.y += this.diameter;
 }

  this.move = function() {
    this.x = (this.x + this.xdir);
  }
}

Thanks.

          //this.y = 1; 
 }

  this.move = function(){
  this.x = (this.x + this.xdir);
  }
}

Here is my code:

    int x = (200);
    int y = (450);

    int a = 0;
    int b = 54;
    int c = 85;

    int xPos = 25;
    int yPos = 25;
    int xdir = 3; 
    int ydir = 40;

    int counter = 0;

    int[][] enemies = generateEnemies();


    int[][] generateEnemies() {
     int[][] enem = new int[54][2];
     int counter = 0;
     for (int xi = 0; xi < 9; xi++) {
       for (int yi = 0; yi < 6; yi++) {
         enem[counter][0] = xi * 50 + xPos;
         enem[counter][1] = yi * 25 + yPos;
         counter++;
        }
      }
      return enem;
    }

    void setup() {
      size(500, 500);
      frameRate(60);
    }

    void draw() {
      background(0);
      player();
      drawEnemies();
      moveEnemiesRight();

    }

    void player() {
      fill(0, 255, 0);
      rect(x, y, 100, 20);
    }

    void drawEnemies() {

      fill(255, 215, 0);
      for (int i = 0; i < 54; i++) {
        rect(enemies[i][0], enemies[i][1], 40, 20);
      }
    }

    void moveEnemiesRight() {
      xPos += 5;
    }

This is super messy and lots of crap going on. This is due to me being very inexperienced in the language. My main problem is that I am unable to make the Enemies move down and across the screen. I tried to adjust their position using the xPos variable but could see it wasn't working and can't seem to see a solution.

Any help or guidance is appreciated. Thank you.

linux not worked for sound library

Please say me, how i made installer for my game with java at once ?

Game video under video there is a source code

i did something like that but this is one time bullet. It has to continuously shoot.

  noCursor();
  background(0);

  image(s1, mouseX,650);
  image(p1, 20, 30);

  if (keyPressed) {
    if (keyPressed == true && key ==' ') {
      image(n1, mouseX, bo);
    }
  }
  bo = bo -10;
}

i defined the specific coordinates for specific images and wrote the code for this but when i clicked code is running but when i released im turning back to select screen.

how can i make this function permanent ?

sorry for grammer btw im'not native !

Here is my alien class:

class Alien 
{
  int y=100;
  int x=10;
  int v=5;

  Alien (int x ,int y)
  {
    this.x=x;
    this.y=y;
  }

//boolean move()
//{
  //y=y+1;
  //x=x;

  //if (y>=0)
  //{
    //return true;
  //}
  //else 
 // {
   //return false;

  //}
//}//end of the boolean

   void move ()
  {

    x=x+v;  // which direction the alien is moving

    if(x> width - 25)

    { 
      v = -5;
      y = y+30;
    }
    if (x==25)
    {
      v =+5;
      y= y+30;
    }

  }//end of move

void create()
{
    fill(255,255,255);
    ellipse(x,y,45,50);
    fill(255,0,0);
    ellipse(x,y,60,25);
}

void update()
{
  create();
  move();
  //y=y+50;

}
}//end of class

i want to get 3 columns with 2 rows of aliens in fixed place with a simple moving pattern for some reason tho i cant get them to display properly with are going diagonally and the other problem that i have is when i try to press "r" and restart the game and set the aliens in the same place where they start it wont work they just keep going from where they left

Any help would be appreciated thanks in advance can put all the code if someone wants to check it
