Running the game

If you execute the game, you will see the menu.

Running the game

The menu allows you to start each of the three levels. But as there is currently no way to complete or fail a level you will need to quit the game and restart it if you want to see the progress on all three.

This is the City level so far.

Running the game

This is the Underground level so far.

Running the game

This is the Mountains level so far.

Running the game

Note the camera is centred around 0,0 because PLAYER_INDEX equals zero and the first object in the objects ArrayList is at 0,0. You could count the characters in the level designs and then change PLAYER_INDEX in the LevelManager class to equal this number. Then the camera will focus on it and you can see more of each level when you run the game. When the player is added to the game the camera will centre around Bob.
