Change the 'if' in line 55 to 'else if'. In the future, please provide the error message, so we don't have to guess what could be wrong. Btw, 'this' will never be 'null'.

Calling a method from the World Class

By 'call a method from the World class', I think they mean 'call a method that is defined in the World class'. The 'showText' method is defined in the World class. You can have your World object call it: <Code Omitted>or have an Actor object that is in the world call it: <Code Omitted>
