JGE++ : A hardware accelerated 2D game engine for PSP/Windows

March 28th, 2006, 13:03 Posted By: dr_watson

Introduction

JGE++ (Jas Game Engine++) is a hardware accelerated 2D game engine for PSP (using GU) and Windows. It's inspired by the popular game engine HGE on MS Windows. In fact the Windows' counterpart is basically a wrapper of HGE.

For more information about HGE, please visit its web site at:

http://hge.relishgames.com.

With JGE++, you can build a project as a Windows executable or a PSP EBOOT image with the same source code without any modification. This means the game development process, including coding, debugging and testing, can be done mainly in Windows. However, since JGE++ is still under development and not heavily tested, it is recommended that the PSP EBOOT image should be built and put onto a PSP for testing from time to time just to make sure everything is working properly.

Of course you may also put in platform specific codes with #if/#else/#endif.

SkyAnimator is introduced with JGE++ v0.2b. It is a visual tool written by
HuangYZ for creating sprite animations. HuangYZ has ported the runtime library to JGE++ and this gives JGE++ a very powerful animation system to play with.

mikmodlib


Directory Structure


To build the JGE++ lib for Windows

Open "JGE.dsw" in JGE directory with Visual Studio 6.0. With the BATCH BUILD option, select "REBUILD ALL".


To build the JGE++ lib for PSP

Change to JGE directory, then

make clean
make install

or just run the batch file "mk.bat"


To build a project for Windows

Open "xxx.dsw" in the project directory with Visual Studio 6.0 and build for either "Release" or "Debug".


To build a project for PSP

Change to the project directory, then

make clean
make

or just run the batch file "mk.bat"


To run on Windows

You need DirectX 8.0+ installed.

Key mapping:


To run on PSP

With firmware 1.50 PSP, use KXploit Tool to transfer the proper EBOOT.PBP
onto your memory stick. Then you need to copy the entire folder "Res" into
the appropriate folder.
