These states have appropriate codes in the update or draw functions to make sure that the game gives the correct prompts or handles the input appropriately.

The player_keyboard function is called from the update function to check to see if any keys are pressed. If the up or down buttons are pressed, then the gun elevation angle is adjusted; if the left or right buttons are pressed, then the power is adjusted (as a percentage of maximum power), and if space is pressed, then the shell is fired. There is an additional test to see if the left-shift key is pressed, which is another option instead of the space to fire the shell. This is included so that the game can work with the Picade or other Raspberry Pi-based arcade machines which map that key to a physical button.

There is a setup function used for all the code that needs to be run when the game is first run. This creates the landscape as well as setting values for many of the variables that will be needed later. There is also additional code to display messages to the user. The code for the complete game is shown in Listing 7-5.import math
