Its a bouncing game, if it hits the bar its get a hit if it doesnt it gets a miss

I wanted to change the ellipse into an alien that i made .. what am i doing wrong??

 

This is the game

Alien myAlien;

void setup()
{
 size (600,400);
 }
  myAlien = new Alien(200, 100, 50, 50);
 float ballX =200;
 float ballY = 100;
 float  speedX =10;
 float speedY =0;
 int hit = 0;
 int miss = 0;
 
 void draw ()
 {
   if(mousePressed) {hit = 0; miss = 0; }
  
   float paddle = 1000/(hit+10);
   if(ballX < 0 || ballX > width) speedX = -speedX ;
   if( ballY > height ){
     speedY = -speedY;
     float distance = abs(mouseX-ballX);
     if (distance < paddle) hit += 1;
     else miss +=1;
   } else   speedY += 1;
  
   ballX += speedX;
   ballY += speedY;
  
   background (100,200,500);
   fill(200,100,50);
  // ellipse(ballX,ballY, 50, 50);
    myAlien.display();
   fill (50,100,200);
  rect(mouseX-paddle, height-10, 2*paddle,10);
 
  fill (0);
  text ("hit : " + hit, 10 , 20);
  text ("miss : " + miss, 10 , 40);
 }
