Create A Program to Animate a Game Map View in Java Assignment Solution

Instructions

Objective

Write a program to create a game map view in java language.

Requirements and Specifications

1. Introduction

   The purpose of this assignment is to help you gain experience with interactive graphics and animation techniques such as repainting, timer-driven animation, collision detection, and object selection. Specifically, you are to make the following modifications to your game:

   • the game world map is to display in the GUI (in addition to the text form on the console),
   • the movement (animation) of game objects is to be driven by a timer,
   • the game is to support dynamic collision detection and response,
   • the game is to support simple interactive editing of some of the objects in the world, and
   • the game is to include sounds appropriate to collisions and other events
2. Game World Map

If you did Assignment2 (A2) properly, your program included an instance of a MapView class which is an observer that displayed the game elements on the console. MapView also extended Container and it was placed in the middle of the game form, although it was empty.

For this assignment, MapView will display the contents of the game graphically in the container in the middle of the game screen (in addition to displaying it in the text form on the console). When the MapView update() is invoked, it should now also should call repaint() on itself. As described in the course notes, MapView should override paint(), which will be invoked as a result of calling repaint(). It is then the duty of paint() to iterate through the game objects invoking draw() in each object – thus redrawing all the objects in the world in the container. Note that paint() must have access to the GameWorld.

That means that the reference to the GameWorld must be saved when MapView is constructed, or alternatively the update() method must save it prior to calling repaint().

Note that the modified MapView class communicates with the rest of the program exactly as it did previously (e.g., it is an observer of GameWorld)
