Basic Game
-
The cat continuously falls but flies up again when the space bar is pressed. If the cat hits any of the pipes or the ground, the player loses.

Teaches:

Gravity

Review of cloning

Review of sprites moving from one edge of the screen to the other
-
-
Start by applying gravity to the cat. There’s a gravity variable that starts off negative and constantly gets more negative. The y- position of the sprite constantly changes by that y-value. When the space bar is pressed, the gravity variable is set to a positive value, so the sprite flies up a bit, but then falls again because the variable is always getting more negative.
-
Make pipes that move across the screen.
-
Encourage the kids to use clones. Have a hidden master pipe sprite and the clones that move across the screen to delete themselves at the end.
-
-
Make the sprite lose if it touches the pipes.
-
Make the sprite lose if it touches the floor
Lesson 6
-
Make a score variable that increases every time the sprite passes another pipe. (Hint: the sprite stays in the same x-position for the whole game, so it passed a pipe when the pipe’s x-position is past the sprite’s).
-
Create a starting screen (“Hit space to play!”), so that the sprite doesn’t fall to the ground as soon as the game starts.
