# SymlinkModels

Replace unwanted Sven Co-op player models with a neutral placeholder by symlinking them to `helmet.mdl`. This keeps your client from rendering anime, NSFW, or other models you don't want to see, while still letting you connect to any server that uses them.

## How it works

For each model ID, the scripts create a relative symlink:

```
svencoop_addon/models/player/<id>/<id>.mdl
    -> ../../../../svencoop/models/player/helmet/helmet.mdl
```

Every suppressed model renders as the default helmet instead.

## Prerequisites

- Sven Co-op installed (scripts must run from the game's root folder, alongside `tags.json`)
- Python 3.8+ **or** PowerShell 5.1+
- **Windows only:** Developer Mode enabled *(Settings → For developers)* **or** run as Administrator — both Windows symlink scripts check for this and warn if neither condition is met

## Files

| File | Description |
|---|---|
| `tags.json` | Model ID lists grouped by category (`anime`, `nsfw`, `vehicle`) |
| `symlink_models.py` | Python — symlink models from `tags.json`, a server path, or a text file |
| `symlink_models.ps1` | PowerShell equivalent of `symlink_models.py` |
| `symlink_downloads.py` | Python — symlink downloaded models that match `tags.json`, then optionally clean up `svencoop_downloads` |
| `symlink_downloads.ps1` | PowerShell equivalent of `symlink_downloads.py` |
| `server_models.txt` | Example model ID dump from a server, usable with `--from-file` |

## Usage

Place the scripts and `tags.json` in your **Sven Co-op root folder** (the directory that contains `svencoop/` and `svencoop_addon/`).

### symlink_models — bulk symlink by source

Symlinks every model ID from the selected source.

**Python:**
```bash
# Default: all IDs in tags.json
python symlink_models.py

# Scan a server's player/ directory
python symlink_models.py --server /path/to/svencoop_addon/models/player

# Read IDs from a text file (one ID per line)
python symlink_models.py --from-file server_models.txt

# Preview changes without writing anything
python symlink_models.py --dry-run
```

**PowerShell:**
```powershell
# Default: all IDs in tags.json
.\symlink_models.ps1

# Scan a server's player/ directory
.\symlink_models.ps1 -Server "C:\path\to\svencoop_addon\models\player"

# Read IDs from a text file
.\symlink_models.ps1 -FromFile server_models.txt

# Preview changes without writing anything
.\symlink_models.ps1 -DryRun
```

### symlink_downloads — process already-downloaded models

Scans `svencoop_downloads/models/player/` for `.mdl` files whose names match IDs in `tags.json`. For each match it creates the symlink in `svencoop_addon`, then lists the source folders and prompts whether to delete them.

**Python:**
```bash
python symlink_downloads.py

# Preview without writing or deleting
python symlink_downloads.py --dry-run
```

**PowerShell:**
```powershell
.\symlink_downloads.py

# Preview without writing or deleting
.\symlink_downloads.ps1 -DryRun
```

The `svencoop_downloads/models/player/` root itself is never deleted — only matched sub-folders.

### Dumping model IDs from a server

If you have access to a server's files (directly or via a network mount), you can dump its player model IDs to a text file and feed it to `symlink_models`:

**Linux/macOS:**
```bash
find /path/to/svencoop_addon/models/player \
     -mindepth 2 -maxdepth 2 -name "*.mdl" -printf "%f\n" \
     | sed 's/\.mdl$//' > server_models.txt
```

**PowerShell:**
```powershell
Get-ChildItem -Path "C:\path\to\svencoop_addon\models\player" -Recurse -Filter "*.mdl" |
    Where-Object { $_.DirectoryName -ne "...\player" } |
    ForEach-Object { $_.BaseName } | Sort-Object -Unique | Set-Content server_models.txt
```

## tags.json

The tag file is a flat JSON object with three category arrays:

```json
{
  "anime":   ["2d_ab_kanna_coco", "sagas_trunks_ssj", ...],
  "nsfw":    [...],
  "vehicle": [...]
}
```

- **anime** (~2,129 entries) — anime character models
- **nsfw** (~579 entries) — adult content models
- **vehicle** (~73 entries) — vehicle models

Model IDs are lowercase with underscores or hyphens. Version suffixes like `_v2` and `_hd` are treated as separate entries. To add or remove a model, edit the relevant array directly. Existing entries are not fully sorted, but try to insert near alphabetical neighbours.

## Output

Each script prints one line per model processed and a summary on exit:

```
[anime] — 2129 models
  create  : 2d_ab_kanna_coco
  skipped : 2d_ab_kratos
  replace : sagas_trunks_ssj

147 symlinks written (147 new, 0 replaced), 1982 already correct
```

Exit codes are 0 on success, non-zero on a fatal error (missing `helmet.mdl`, bad path, etc.).
