*********************************************************************** * * * GameBlade by Jarek Ilski ( Nokturn32()poczta.onet.pl ) * * Distribution: EXBackground20021007 * * * * GameBlade Version: 20021007 * * * *********************************************************************** About GameBlade: ---------------- Please read the file README-GB for information about the GameBlade. License: -------- Please read the file COPYING for the license. The license is the GPL. Last update: ------------ 07 Oct 2002 ( Version Nr. 20021007 ) About this distribution: ------------------------ This is an example distribution for demonstrating the process of loading and displaying a background using the GameBlade. The changes compared to a Base distribution are: -"makefile", changed the binary name to "EXBackground" -"headers/GB_Definitions.h", changed GAMEBUILD and the video mode settings to 800x600 and windowed mode -"main.cpp", added three lines of code to display the background file "gfx/back.jpg" -"gfx/back.jpg", added this 800x600 file to the distribution -"gfx/8x8font.bmp", removed this file because it is not used in this distribution Where to go from here? ---------------------- Read the file README-GB from this directory and the file "HOWTO" in the doc directory or download example distributions. Have fun, Jarek Ilski, 07. Oct. 2002 *********************************************************************** * * * GameBlade by Jarek Ilski ( Nokturn32()poczta.onet.pl ) * * * * Version: 20021007 * * * *********************************************************************** License: -------- Please read the file COPYING for the license. The license is the GPL. Last update: ------------ 07 Oct 2002 ( Version Nr. 20021007 ) What is the GameBlade? ------------------------ The GameBlade is a little helper library made only of headers ( and a .cpp file ) which makes SDL Game programming even easier than it already is. For whom is the GameBlade? ---------------------------- The GameBlade is for people who have only a little time but would none the less like to code a game and for people who don't like to get into technical stuff. You can easily code a game with sound, music, keyboard handling and nice looking bitmap graphics in one day. For whom is the GameBlade the wrong choice? --------------------------------------------- Actually, the GameBlade can be useful to anyone, also to people who want to code 3D games or games with mouse support or people who would like to code professional games. If you like, you can use just one part of the library, for example if you are only interested in music playback, why not use this part? What can the GameBlade do? ---------------------------- Actually, the GameBlade can only call other libraries, like SDL, SDL_image and SDL_mixer. But if you ask what it was meant to make easier, here you have a list: - Take care of the video mode ( SDL ) - Load and display sprites in various formats like BMP, JPG, PNG, PCX and many more ( SDL_image ) - Load and display fullscreen backgrounds ( same formats supported like for sprites ) ( SDL_image ) - Handle some basic events like the ESC button and closing the window ( SDL ) - Get input from the keyboard and handle it ( SDL ) - Open and play a sound ( formats like Microsoft WAVE, VOC etc etc ) ( SDL_mixer ) - Open and play background music ( supports formats like OGG, MIDI and MP3 ) ( SDL_mixer ) - Provides a very simple set of functions for displaying text in a 10x16 bmp font ( font included ) As you see, this is all you need to code a little game. Probably you will replace the font by an own one or use another font library, because the set of functions of the GameBlade is very limited Concept: -------- This "library" consists of a main file ( main.cpp ) and many header files. This library is not installed to your system but your game or application is built on top of it. Generally that means: - You "tar xvfz GameBlade-Base20021007.tar.gz" - You treat all the new files and directories as if they were part of your project and you edit them as you like. If you like, you can completely change all the code, or you can use only parts of it. Every header stands for a new section of the library. Some headers will not be so interesting for you, while the headers like GB_Definitions.h, GB_Functions.h, GB_Globals.h, GB_Classes.h and GB_FilterEvents.h were made to be changed by you. How do I check if it works? --------------------------- If you are using Linux, just go to the directory with the file "makefile" and type "make". If you get no errors, it works. What are the requirements for this library? ------------------------------------------- All you need is a C/C++ compiler, SDL (I used versions 1.2.5 and 1.2.4, but all new versions should be ok), SDL_image and SDL_mixer. If you don't have these, here is a tip where you can get them: C/C++ compiler: I use GCC, which is freely available for Linux, Windows and many other systems, you should able to find it everywhere SDL : www.libsdl.org, there you can find the newest versions SDL_image : www.libsdl.org, look for "Libraries" SDL_mixer : www.libsdl.org, look for "Libraries" Well, then what do I do next? ----------------------------- Now you can start working on your game/application. First I would advise you to look through the headers and to look at the main.cpp file, much of the code is commented and easy to understand. Please also read the files in the doc directory. Have fun! -Jarek Ilski, 07. Oct. 2002 |
