Program freezes when I touch the third poison vial.

Dave StSomeWhere I have had a look at console, see the error you are talking about, however I replicated the code for winning message except for this bit here, that is the only difference.

what within this has given me the undefined function? // when the player wins the game if (won) { winningMessage.text = "YOU WIN!!!"; } if (lives ==0 ){ deathMessage.text = " GAME OVER!"; }

as all other code is identical between the 2 functions ( obviously excluding naming)

Thanks again for the feedback.

The issue is with your itemHandler() function (line 67) - maybe those two if statements at the end don't need to be there - what happens if you comment them out - or maybe create the createBadge() and deathMessage() functions?

// when the player collects an item on the screen
function itemHandler(player, item) {
  item.kill();
  if (item.key === 'coin') {
     currentScore = currentScore + 10;
  } else if (item.key === 'poison') {
     lives = lives - 1;
  } else if (item.key === 'star') {
     currentScore = currentScore + 20;
  }
  if (currentScore === winningScore) {
      createBadge();
  }
  if (lives == 0) {
      deathMessage();
  }
}

Dave StSomeWhere as per your suggestions , I commented out the 2 if statements, and same result, once I get to the third poison vial the game freezes,

I think the issue is something I havent learnt yet ( this is my first attempt at programming ) I will continue with the techdegree course and perhaps revisit it in a week or 2 and see if the issue is possibly a bit clearer then.

thanks again for the help.

Sounds good, just remember to enjoy the debugging - it is the fun part...

Another good debugging tool is the console.log() method

When I use the following code - it doesn't freeze on the third poison vial:

function itemHandler(player, item) {
  item.kill();
  if (item.key === 'coin') {
     currentScore = currentScore + 10;
  } else if (item.key === 'poison') {
     lives = lives - 1;
  } else if (item.key === 'star') {
     currentScore = currentScore + 20;
  }
  if (currentScore === winningScore) {
      console.log(' calling createBadge()');   // console.log here
  }
  if (lives == 0) {
      console.log(' calling deathMessage()');  // console.log here
  }
}

good luck and enjoy
