OpenRaider

OpenRaider

OpenRaider is an Open Source implementation of the classic Tomb Raider Game Engine. It was abandoned in 2003.

This project aims to get OpenRaider in a more usable state, maybe one day even being able to play the old Tomb Raider games flawlessly…

If you just want to see OpenRaider doing something on your Mac, without installing any of the dependencies needed to build OpenRaider, grab the Mac App Bundle from the most recent release.

It seems as if OpenRaider will currently only work on Little-Endian platforms. This is not nice and will hopefully be fixed in the future!

Configuration

OpenRaider needs some configuration files, and level data and assets from custom levels or the Tomb Raider games. These are stored in ~/.OpenRaider. Running make setup will create/copy the necessary files and directories.

You still need to add level files in ~/.OpenRaider/paks/ and add them to ~/.OpenRaider/OpenRaider.init. Dust off your old Tomb Raider CDs or grab some custom levels from the interwebs.

Documentation

All previously included documentation was moved into the OpenRaider Repo Wiki. Also take a look at the BUGS, TODO and Requirements.

A more or less recent Doxygen documentation of OpenRaider should be on the Github Pages for OpenRaider.

Dependencies

Basically, OpenRaider depends on the following:

• OpenGL
• SDL2 & SDL2-TTF
• OpenAL & ALUT
• zlib
• cmake as build system

On Mac OS X 10.9 with XCode and MacPorts installed, the following should be enough to get all dependencies that are available as port:

sudo port install cmake zlib libsdl2 libsdl2_ttf

A similar command for the package manager of your favorite Linux Distribution should do the trick.

cmake is also needed to build freealut, which you’ll need to enable sound output on Mac OS X. Get, compile and install freealut like this:

git clone git@github.com:vancegroup/freealut.git
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX:STRING="/usr/local" -DCMAKE_C_FLAGS:STRING="-O2"
make
sudo make install

Linux Distributions will probably provide an ALUT library ready to install with their package manager, so you won’t need to compile freealut.

Building

Do a standard cmake out-of-source build to get a debug configuration and then run the resulting executable:

mkdir build && cd build
cmake ..
make run

On Mac OS X, running make install will produce a (more or less) distributable OpenRaider.app bundle.

You can run a static analysis with cppcheck using make check, make checkFull or make checkConfig.

A Doxygen API documentation can be created with make doc.

make clean should remove all intermediary files. make run will run the binary.

Usage

Configuration file

OpenRaider will try to load ~/.OpenRaider/OpenRaider.init or, if it doesn’t exist, OpenRaider.init from the current directory. Running make setup will create a minimal configuration in your home directory.

The configuration file format is very simple:

• Anything following a # up to the next \n will be ignored.
• Lines starting with an @ mark a “preprocessor” command. The only one currently implemented is @include, allowing you to include another file as configuration file.
• Lines surrounded with [], eg. [Engine.OpenGL.Driver] set the mode for following commands.
• Everything else is interpreted as command for the current mode.

Level PAKs

You can use paks from any Tomb Raider version supported and most user made paks for Tomb Raider. Only PHD, TR1, TR2, TR3, and TR4 paks are supported as of this writing.

Sound FXs

Setting up external sound SFX, for TR2 and TR3 paks only.

TR2 and TR3 paks (both have file extension .tr2) don’t have sound data contained in the pak itself, but instead they share a common SFX file (often MAIN.SFX) for each pak from a given Tomb Raider version.

Previously, OpenRaider tried to load an SFX file with the same name as the level file, with .sfx added to the end. You had to create a symlink for each level to the SFX file if you were using original Tomb Raider levels, like this:

cd ~/.OpenRaider/paks/tr3/
cp /mnt/cdrom/data/MAIN.SFX .
for i in *.tr2; do ln -s MAIN.SFX $i.sfx; done

Now, OpenRaider just tries to load a MAIN.SFX in the same folder as the level file. If you want to change this behaviour, this happens around line 1075 of src/OpenRaider.cpp.
