In this chapter, we will implement the remaining game objects that represent our actors in the game world. These are the player character bunny head and both the collectible items: the gold coin and the feather power-up. We will complete the level loader by adding support for the actor game objects so that these are handled properly when a level is loaded.

The game will be extended to feature a simple physics simulation that allows any game object to be moved using physical properties, such as velocity, acceleration, and friction. In addition, the game logic will also need to detect collisions of the game objects to trigger certain events. For example, we want the player character to be able to jump, stand, and walk on a rock (platform), collect items by walking over them, and lose a life when it falls into the water. The game logic will also include a check to find out whether the game over condition is met so that the game immediately ends and a GAME OVER text...
