(First, open the Leaf class. Take a look at the act() method. It calls
two methods – falling() and checkForMiss(). The falling() method
causes the leaves to flutter downwards. The checkForMiss() method
checks to see if the baby missed the leaf – in other words, the leaf
has hit the bottom without being caught. Add code to play the
“fallenthing” sound (look in the images folder to find the file for this
sound). This will go inside the IF clause. Test – everytime a leaf hits the
bottom, you should hear this noise.)
Above is part of my assignment, i cannot get the sound to compile it gives me an error saying cannot find symbol
