Java代写：CS335 Space Racing Simulator

发表于 | 分类于
本题需要基于OpenGL开发一个竞速小游戏，需要了解OpenGL的编程框架，以及掌握OpenGL函数库的基本用法，并以此来实现竞速小游戏。整个游戏地图包括边界、坡度、障碍物等。

Requirement

This final project is a group project, each group should have two people. The goal of this project is to develop a java based racing game.

The space racing game should provide the following functions:

  1. One computer graphics environment
  2. User-controlled car
  3. User controlled viewpoint
  4. Game AI

The racing vehicle car’s movement can be determined by its velocity and acceleration vectors.

Analysis

本题需要基于OpenGL开发一个竞速小游戏，需要了解OpenGL的编程框架，以及掌握OpenGL函数库的基本用法，并以此来实现竞速小游戏。整个游戏地图包括边界、坡度、障碍物等。

本题的学习曲线较为陡峭，但是如果掌握了OpenGL的基本编程方法，难度也不是很大。此外，一个值得注意的地方是，本题的AI需要额外设计，对障碍物、边界等地区，进行判断。
