If you did not manage to get through “Lists, Loops and Ifs” then you can continue to go through it here:
The next thing to work on is the ability manipulate the objects once the code has begun to run so that you can start or to change something about the code once it is running. Think of this being similar to how you would program a remote control for a remote control car so that it responds to the movement of the joystick.
The next step in developing a game is that we have to figure out how to tell the computer what to do when objects interact with each other. In the real world when objects interact they will often bounce or break depending on the force and how the object is made. Using physics language we are talking about collisions. The next worksheet takes you through how to code for collisions:
