DEBUG: ASTEROID ATTACK In this project, falling rock from the sky threatens to flatten the city. Ideally, when the rock falls, and touches any of the buildings, the building should lower! However, there seem to be some bugs in the code. Fix them (list below)l. 1) Get the rock to appear at a random location on the top of the stage 2) Get the rock to then fall downwards 2) Get the rock to to back to a random position on the top of stage, every time it touches a building, or the bottom sprite (the purple line at the bottom!) Hint: It is all about XY coordinates and broadcasting!
