Click the preview button to view the game. Currently, there are 3 stars on screen. Click the Editor button and add two more stars, bringing the total number of stars to 5. Make sure none of the stars overlap with any other stars.

I watched the video on conditional statements.

I am not able to figure out how to add 2 more stars. I looked for the number 3 to change to 5. Maybe I am not understanding the question. If anyone has figured it out please help. Thank you!

In the code below is where you add the stars. You will need two more starCreate with different locations, so they don't overlap.

function createStars() {
    stars = game.add.physicsGroup();

    starCreate(425, 100, 'star');
    starCreate(315, 100, 'star');
    starCreate(175, 200, 'star');

}
