Pico碰到Nano，會停下說“Tag, your it!”(碰到你了，換你當鬼），然後Ｎano說“Ｍy Turn"(換我） In this project, when the green flag is clicked Pico should move towards Nano. When Pico reaches Nano, Pico should say “Tag, your it!” and Nano says “Ｍy Turn" But something is wrong! Pico doesn’t say anything to Nano How do we fix the program?
