A 12 year old German boy from our school has created a Scratch project with a figure which can be controlled to jump around the room. Bounce-effect is added to the landing of the figure so that this little game looks very professional.
The student learned the concept of variable from a youtube tutorial video and used this concept in his project. The landing of the figure is imitated with a changing velocity which is added to the y coordinate continuously. Another variable "bounce count" is used to count down the time of bounces - in each bounce, the velocity is set to 1/5 of the previous and after 5 times, velocity value is set to 0.
