Space Invaders Freeglut Project

C++ graphics program enrich with many development in the technology. Opengl graphics library is one of them that lead to the vast improvement in the computer graphics programming with free apis. Glut The OpenGL Utility Toolkit is a library of utilities for OpenGL programs. We have many program like Flag hoisting C++ program utilize the use of Glut. There is an alternative to Glut, called Freeglut. In this post we will have a program using freeglut. The is named as Space Invaders.



What is Freeglut?

FreeGLUT is an alternative to the OpenGL Utility Toolkit (GLUT) library, the open source alternative. GLUT (and hence FreeGLUT) allows the user to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard and joystick functions. FreeGLUT is intended to be a full replacement for GLUT, and has only a few differences.

Since GLUT has gone into stagnation, FreeGLUT is in development to improve the toolkit. The origninal writer of Freeglut is Pawel W. Olszta. Andreas Umbach and Steve Baker has made significant contribution to Pawel for freeglut.

Space Invaders Freeglut Project

  1. This program is similar to other opengl computer graphics programs, where we will use the freeglut libraries instead of glut. <GL/freeglut.h> is replacing <GL/glut.h>
  2. The program starts with splash screen, which uses the textures to display the strings. There is separate file used to write the code for the textures.
  3. This is a game project, where there is a aircraft loaded with weapons. Use the gun to target the enemy before the heap crosses the safeline.
  4. Each shot with accuracy give the points to player. Score is displayed as well as overall high score .
  5.   Game have different options to choose from like play, exist and choose the difficulty levels.


Glut and Freeglut

This program can be used with the glut as well. Instead of using <GL/freeglut.h> use <GL/glut.h>. Also if some error persist,use the glut alternative  of freegult. 

You can download the source code as well as the textures c code without any guaranty. 

The source code is hosted out of our control, hence we disclaim to any liabilities arose due to use of the code. The copyright is hold by owner as stated in the source code, we govern with the same.We congrats the writer to provide us such a wonderful projects in freeglut.
