### Download
This project is currently in **Alpha** state, so expect bugs.  
Builds available at [https://releases.axiodl.com](https://releases.axiodl.com).

### Platform Support
* Windows 10 (64-bit, D3D11 / Vulkan)
* macOS 10.15+ (Metal)
* Linux (Vulkan)
    * Follow [this guide](https://github.com/lutris/docs/blob/master/InstallingDrivers.md) to set up Vulkan & appropriate drivers for your distro.

### Usage (GUI)

Windows:
- Open `metaforce-gui.exe`

macOS:
- Open `Metaforce.app`

Linux: 
- Ensure AppImage is marked as executable: `chmod +x Metaforce-*.AppImage`
- Open `Metaforce-*.AppImage`

### CLI usage (GC versions)

* Extract ISO: `hecl extract [path].iso -o mp1`
  * `mp1` can be substituted with the directory name of your choice
* Repackage game for Metaforce: `cd mp1; hecl package`
* Run Metaforce: `metaforce mp1/out`

### CLI usage (Wii versions)

**IMPORTANT**: Trilogy main menu currently doesn't work, and requires the `--warp 1 0` command line arguments to get in-game.  

NFS files dumped from Metroid Prime Trilogy on Wii U VC can be used directly without converting to ISO.

* Extract ISO or NFS: `hecl extract [path].[iso/nfs] -o mpt`
  * `mpt` can be substituted with the directory name of your choice
* Repackage game for Metaforce: `cd mpt; hecl package MP1`
  * The `MP1` parameter is important here.
* Run Metaforce: `metaforce mpt/out --warp 1 0`

#### Metaforce options (non-exhaustive)

* `-l`: Enable console logging
* `--warp [worldid] [areaid]`: Warp to a specific world/area. Example: `--warp 2 2`
* `+developer=1`: Enable developer UI

### Build Prerequisites:
* [CMake 3.15+](https://cmake.org)

### Prep Directions

```sh
git clone --recursive https://github.com/AxioDL/metaforce.git
cd metaforce
```

### Update Directions

```sh
cd metaforce
git pull
git submodule update --recursive
```

### Build Directions

For Windows, it's recommended to use Visual Studio. See below.

#### ninja (Windows/macOS/Linux)

Builds using `RelWithDebInfo` by default.

```sh
cmake -B out -G Ninja # add extra options here
cmake --build out --target metaforce hecl visigen
```

#### CMake configure options
- Build in debug mode (slower runtime speed, better backtraces): `-DCMAKE_BUILD_TYPE=Debug`
- Use clang+lld (faster linking): `-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++`
- Optimize for current CPU (resulting binaries are not portable): `-DMETAFORCE_VECTOR_ISA=native`

#### CLion (Windows/macOS/Linux)
*(main development / debugging IDE)*

Open the repository's `CMakeLists.txt`.

Optionally configure CMake options via `File` > `Settings` > `Build, Execution, Deployment` > `CMake`.

#### Qt Creator (Windows/macOS/Linux)

Open the repository's `CMakeLists.txt` via File > Open File or Project.

Configure the desired CMake targets to build in the *Projects* area of the IDE.

#### Visual Studio (Windows)

Verify all required VS packages are installed from the above **Build Prerequisites** section.

Open the `metaforce` directory in Visual Studio (imports CMake configuration).

MSVC and clang-cl configurations should import automatically.

#### Xcode (macOS)

```sh
cmake -G Xcode ../metaforce
```

Then open `metaforce.xcodeproj`

#### Optional Debug Models
We provide custom debug models for use to visualize certain aspects of the game such as lighting, in order to use 
these models you may download them from https://axiodl.com/files/debug_models.zip and extract to `MP1/URDE` in an 
existing HECL project (assuming paths are relative), then run the following command:

```sh
hecl package MP1/URDE
```
This will cook and package the debug models and will automatically enable rendering of lights in a debug build of Metaforce.

### Blender Known Issues
On Windows it is known that paths >240 characters will cause blender to fail while attempting to open/create a file, causing hecl to stall.  
We currently do not have a good fix for this issue, however a workaround is to place hecl near the root of your directory tree
and executing from there e.g:  
`D:\HECLProjects\`  
Another work around is to install a version of python that matches the one blender ships with and renaming the python directory in the blender directory to `python.bak`.  
This will force blender to use the system's python if it's available and will not have the same path limitation
