A Rust-based Godot 4 extension, using the gdextension crate, for loading EverQuest assets at runtime from the original data files. It depends heavily on the libeq crate, and is really a thin wrapper around it with a translation layer into Godot's objects and conventions.

The example project in this repository attempts to show, in the most concise way possible, how to build Godot assets with this plugin. For a more advanced example, I will be setting up a separate repository. To run the example project, you must provide .s3d files yourself, and either put them in the eq_data folder, or create an environment variable called EQDATA that points to a folder containing .s3d files.

To run the example, first build the GDExtension: cargo build Then you can either open the example project in the Editor, or run it in the command line: godot4 --path ./example/EQLoaderExample

There are some command line options. The default action is to load a random zone and character file.

Load a specific zone, including its characters: godot4 --path ./example/EQLoaderExample -- --zone misty

Load a character file only: godot4 --path ./example/EQLoaderExample -- --chr global_chr

First, make sure to follow the setup instructions for the gdextension crate. At the time of this writing, that includes setting the GODOT4_BIN environment variable to point to your Godot4 binary. Then...

cargo build

Or for a release build:

cargo build --release

After building, copy godot_eqloader.dll (or .dylib or .so) from ./target/release/ into your project directory somewhere.

Create a file called EQLoader.gdextension next to it that looks something like this:

[configuration]
entry_symbol = "gdext_rust_init"

[libraries]
linux.64 = "res://./godot_eqloader.so"
macos.64 = "res://./godot_eqloader.dylib"
windows.64 = "res://./godot_eqloader.dll"

The following features are currently implemented:

WLD fragment access

• S3DWld - Provides methods for getting all the fragments described below
• S3DMesh - A wrapper around DMSPRITEDEF and DMSPRITEDEF2, which represent all meshes
• S3DMaterial - A wrapper around MATERIALDEF and its SIMPLESPRITEDEF and BMINFO references, which represent materials and their texture properties
• S3DActorDef - A wrapper around ACTORDEF, which represents actors in the world such as placeable objects and characters
• S3DActorInstance - A wrapper around ACTOR, which represents instances of ACTORDEFS in a zone
• S3DHierSprite - A wrapper around DMHIERARCHICALSPRITE, which represents skeleton-based objects such as characters, and their animations (TRACK and TRACKDEF fragments)
• S3DUnknownFragment - A wrapper around unsupported fragments, for analysis. To actually look at the fragment data, see the "Extra Features" section below.

Archive access

• Loading .wld files as S3DWld objects (described above)
• Loading .bmp files as Godot Images and ImageTextures
• Loading .wav file as Godot AudioStreamWAV

The following features may be supported in the future, and any help is welcome:

• Regions (For the sole purpose of detecting whether the player is in a particular special region such as water, zoneline, etc)
• Lights
• Blitsprites

This library can be compiled with a serde feature, which adds a new method to all fragments: as_dict. This returns a serde-serialized representation of the underlying raw fragment data as a Godot Dictionary, for analysis. For fragments that do not have a wrapper, you can get them and look at their data with wld.at(fragment_index).as_dict().
