In this project, the scene changes when you press the right arrow key. The star of the project -- a dinosaur -- should be hidden in every scene, except when the scene transitions to the auditorium backdrop. In the auditorium, the dinosaur should appear and do a dance. But the dinosaur is always present and is not dancing at the right time. How do we fix the program?
First the backdrop switches to auditorium show x by y, forever all the costumes point 90 wait 0.5 second, lastly backdrop switches hide and stop other sprites.
