Hello I want to make a way to make mousePressedOver in code.org game lab so you only click once

Question

So in my CS class I have been working on code.org I wanted to make something but it doesnt work because mousePressedOver is not one click. I don't really know anymore coding so this is why I need help, I couldn't find any answers online.

// framerate 
World.frameRate = 120;

// sound
playSound("baller.mp3");

// variables+sprites
var balloon = createSprite(200, 200);
balloon.setAnimation("balloon");
balloon.scale = 0.1;
var baller = createSprite(200, 200);
baller.setAnimation("baller");

look at the comment where it says secret that is where I need help.

//draw loop 
function draw() {

// background
background("white");

  // scale and visible
  balloon.scale = balloon.scale + 0.03;
  baller.visible = false;
  
  // if statement
 if (balloon.scale > 0.5) {
    baller.visible = true;
    balloon.visible = false;
  }
  
    // secret
if (mousePressedOver(baller))  {
  var shhhh = createSprite(200, 200);
shhhh.setAnimation("thing");
shhhh.scale = 0.3;
  textSize(25);
 text("You werent supposed to see this...", 20,50);
 baller.visible = false;
}


   // draw sprites
  drawSprites();
}

Answer 1

You can use if (mousePressedOver(baller) && mouseWentDown("leftButton")) {} to check if the Sprite is clicked once.

Edited:

Define a boolean variable ;

var showHiddenText = false;

Add this after you define background("white");

if(showHiddenText){
  text("You werent supposed to see this...", 20,50)
}

Control it by changing the boolean value;

if (mousePressedOver(baller) && mouseDown())  {
 showHiddenText = true;
}
