# NRes Game Resource Unpacker
|
|
|
|
At the moment, this is a demonstration of the NRes game resource unpacking algorithm in action.
|
|
It unpacks 100% of the NRes game resources for the game "Parkan: Iron Strategy".
|
|
The unpacked resources can be packed again using the [packer](../packer) utility and replace the original game files.
|
|
|
|
__Attention!__
|
|
This is a test version of the utility.
|
|
It overwrites existing files without asking.
|
|
|
|
## Building
|
|
|
|
To build the tools, you need to run the following command in the root directory:
|
|
|
|
```bash
|
|
cargo build --release
|
|
```
|
|
|
|
## Running
|
|
|
|
You can run the utility with the following command:
|
|
|
|
```bash
|
|
./target/release/unpacker /path/to/file.ex /path/to/output
|
|
```
|
|
|
|
- `/path/to/file.ex`: This is the file containing the game resources that will be unpacked.
|
|
- `/path/to/output`: This is the directory where the unpacked files will be placed.
|
|
|
|
## How it Works
|
|
|
|
The structure describing the packed game resources is not fully understood yet.
|
|
Therefore, the utility saves unpacked files in the format `file_name.file_index` because some files have the same name.
|
|
|
|
Additionally, an `index.json` file is created, which is important for re-packing the files.
|
|
This file lists all the fields that game resources have in their packed form.
|
|
It is essential to preserve the file index for the game to function correctly, as the game engine looks for the necessary files by index.
|
|
|
|
Files can be replaced and packed back using the [packer](../packer).
|
|
The newly obtained game resource files are correctly processed by the game engine.
|
|
For example, sounds and 3D models of warbots' weapons were successfully replaced.
