## Quick setup guide
**Note:** For support please join our [Discord](https://discord.gg/T5vZU6UyeG).
### Requirements
* Java SE - 17 ([link](https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html))
**Note:** If you just want to **run it**, then **jre** only is fine.
* MongoDB (recommended 4.0+)
* Proxy daemon: mitmproxy (mitmdump, recommended), Fiddler Classic, etc.
### Running
**Note:** If you updated from an older version, delete `config.json` to regenerate it.
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 move your `BinOutput` and `ExcelBinOutput` folders there *(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 ...
- 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).
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
You may want to use this command (`java -jar grasscutter.jar -gachamap`) to generate a mapping file for the gacha record subsystem. The file will be generated to `GRASSCUTTER_RESOURCE/gcstatic` folder. Otherwise you may only see number IDs in the gacha record page.
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`

### Bonus
- Teleporting
- When you want to teleport to somewhere, use the in-game marking function on Map.
- Mark a point on the map using the fish hook marking (the last one.)
- (Optional) rename the map marker to a number to override the default Y coordinate (height, default 300.)
- Confirm and close the map.
- You will see your character falling from a very high destination, exact location that you marked.
# 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
