* Spawning monsters via console
* Inventory features (recieving items/characters, upgrading items/characters, etc)
## Quick setup guide
**Note:** for support please join our [Discord](https://discord.gg/T5vZU6UyeG)
### Requirements
* Java SE - 17 ([mirror link](https://github.com/adoptium/temurin17-binaries/releases/tag/jdk-17.0.3+7) since Oracle required an account to download old builds)
**Note:** If you just want to **run it**, then **jre** is fine
* MongoDB (recommended 4.0+)
* Proxy daemon: mitmproxy (mitmdump, recommended), Fiddler Classic, etc.
### Running
**Note:** If you update from an older version, delete `config.json` for regeneration
1. Get `grasscutter.jar`
- Download from [actions](https://nightly.link/Grasscutters/Grasscutter/workflows/build/stable/Grasscutter.zip)
- [Build by yourself](#Building)
2. Create a `resources` folder in the directory where grasscutter.jar is located and bring your `BinOutput` and `ExcelBinOutput` folders into it *(Check the [wiki](https://github.com/Grasscutters/Grasscutter/wiki) for more details how to get those.)*
3. Run Grasscutter with `java -jar grasscutter.jar`. **Make sure mongodb service is running as well.**
### Connecting with the client
½. Create an account using [server console command](#Commands).
1. Redirect traffic: (choose one)
- mitmdump: `mitmdump -s proxy.py -k`
Trust CA certificate:
**Note:**The CA certificate is usually stored in `% USERPROFILE%\ .mitmproxy`, or you can download it from `http://mitm.it`
Double click for [install](https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate#installing-a-trusted-root-certificate) or ...
- Via command line
```shell
certutil -addstore root %USERPROFILE%\.mitmproxy\mitmproxy-ca-cert.cer
```
- Fiddler Classic: Run Fiddler Classic, turn on `Decrypt https traffic` in setting and change the default port there (Tools -> Options -> Connections) to anything other than `8888`, and load [this script](https://github.lunatic.moe/fiddlerscript).
- [Hosts file](https://github.com/Melledy/Grasscutter/wiki/Running#traffic-route-map)
2. Set network proxy to `127.0.0.1:8080` or the proxy port you specified.
**you can also use `start.cmd` to start servers and proxy daemons automatically**
### Building
Grasscutter uses Gradle to handle dependencies & building.
**Requirements:**
- Java SE Development Kits - 17
- Git
##### Windows
```shell
git clone https://github.com/Grasscutters/Grasscutter.git
cd Grasscutter
.\gradlew.bat # Setting up environments
.\gradlew jar # Compile
```
##### Linux
```bash
git clone https://github.com/Grasscutters/Grasscutter.git
cd Grasscutter
chmod +x gradlew
./gradlew jar # Compile
```
You can find the output jar in the root of the project folder
## Commands
You might want to use this command (`java -jar grasscutter.jar -handbook`) in a cmd that is in the grasscutter folder. It will create a handbook file (GM Handbook.txt) where you can find the item IDs for stuff you want
There is a dummy user named "Server" in every player's friends list that you can message to use commands. Commands also work in other chat rooms, such as private/team chats. to run commands ingame, you need to add prefix `/` or `!` such as `/pos`

# Quick Troubleshooting
* If compiling wasn't successful, please check your JDK installation (JDK 17 and validated JDK's bin PATH variable)
* My client doesn't connect, doesn't login, 4206, etc... - Mostly your proxy daemon setup is *the issue*, if using
Fiddler make sure it running on another port except 8888
* Startup sequence: Mongodb > Grasscutter > Proxy daemon (mitmdump, fiddler, etc.) > Client
