LUA PROGRAM HELP
I have the below program. I need help adding another baloon that follows the below rules:
-Add a yellow balloon (the image file name will be “yellow.png”).
-Around half of the time, when yoo click on the yellow balloon, it will add 10 points to your score, the other half it will take away 10 points. If you miss it, one point will be taken away. Have the “boom.png” appear when the points are added, and “ouch.png” when they are taken away.

Explanation / Answer
In the loop we are randomly calculating the value and displaying new ballon or bomb. In that loop I have added one more condition to print yellow baloon along with green baloon too...
Start physics engine

score Text = display.new Text(score, halfW, 10)

local function balloonTouched(event)
