Build a simple shooter game
In this project, I show how to shoot an octopus along a parabolic (curved) path by using Scratch's built-in timer and a simple calculation. As the cannon continues to hit the target, the game gets more difficult by building a taller wall between the cannon and the target. Figure 1 shows the game.
The actual sprites used for this game do not matter too much, but I will use four sprites total: a cannon, a bullet, a wall, and a target. In my setup, the bullet is an octopus and the target is a character from the list of fantasy sprites included with Scratch. The wall can be drawn in Scratch's Paint Editor.
