openjazz2's Introduction

OpenJazz2

An Open Source Jazz Jackrabbit 2 engine project.

This project uses the art assets from the game engine directly to play the game. It doesn't need to convert the art assets into another format to be playable. I wrote this using C++ and OpenGL and SDL for windowing. This is in no way anywhere close to functional, but it makes a good proof of concept for how you would load the art assets and render the levels, and it has a pretty basic collision detection and resolution system that would be a good starting point for making a serious attempt at building a new engine for Jazz Jackrabbit 2.

openjazz2's Issues

Level loading problem

Hi faha223! I recently started to work on a port of Jazz Jackrabbit 2 in Unity Engine. Using parts of your code and the documentation found at https://www.jazz2online.com/wiki/ I managed to get the tilesets to load and also get some of the levels to load (such as Castle1, Castle1n, Damn1, Damn2 and a few others) but most of them won't load and give a "index out of range" error when reading the buffer of Data4. Strange enough, all the levels have the same version still some of them load without problems while some won't load.
Do you have the same problem? If not, do you know what might be causing it? I suspect that it has something to do with the TileWidth bit being checked for certain layers. (something about this TileWidth bit at https://www.jazz2online.com/wiki/J2L_File_Format#h-6)
