How do I add lives? Do I just change the values of the currentScore and winningScore? Or do I have to call new variables

Im not sure how to make a 3 life system. I used ctrl f to find some type of "lives" to find some type of variable to build a separate system, but I cant find anything.

Hi Jesse - it's likely calling for you to add extra logic to the program to give it this functionality.

It might look similar to a function demonstrated in the preceding video at 1:10 ( The player would I guess start with 3 lives (this figure being held in a variable) and then when something happens to cause the player to lose a life this runs the extra function you created which alters the lives variable from 3 to 2.

I also don't get it... I get how to make it so that hitting poison subtracts a life, but not how to get the lives counter in there in the first place.

What I did was I added new variable on the top.

var lives = 3;

Hello, if I this can be helpful...

  • I have added new var named currentLifes
  • I have added in create function this: loosingMessage= game.add.text(, 275, "", { font: "bold 48px Arial", fill: "white" }); loosingMessage.anchor.setTo(0.5, 1);
  • I have added this in a update function : text.text = "SCORE: " + currentScore +" LIFES: "+ currentLifes;
  • I added this function: //when the player loose lifes function looseLifes() { loose= true }
  • I have added this function inside itemHandler function: if (currentLifes === 0) { looseLifes(); }
