# Current features
* Logging in
* Combat
* Spawning monsters via console
* Inventory features (recieving items/characters, upgrading items/characters, etc)
* Gacha system
* Friends list
* Co-op *partially* work
# Quick setup guide
### Prerequisites
* JDK-8u202 ([mirror link](https://mirrors.huaweicloud.com/java/jdk/8u202-b08/) since Oracle required an account to download old builds)
* Mongodb (recommended 4.0+)
* Proxy daemon: mitmproxy (mitmdump, recommended), Fiddler Classic, etc.

### Starting up Grasscutter server (Assuming you are on Windows)
1. Setup compile environment `gradlew.bat`
2. Compile Grasscutter with `gradlew jar`
3. Create a folder named `resources` in your Grasscutter directory, bring your `BinOutput` and `ExcelBinOutput` folders into it *(Check the wiki for more details how to get those.)*
4. 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* below
1. Run a proxy daemon: (choose either one)
	- mitmdump: `mitmdump -s proxy.py --ssl-insecure`
	- 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. Trust CA certificate:
	- mitmdump: `certutil -addstore root %USERPROFILE%\.mitmproxy\mitmproxy-ca-cert.cer`
2. Set network proxy to `127.0.0.1:8080` or the proxy port you specified.
4. *yoink*

* or you can use `run.cmd` to start Server & Proxy daemon with one click

# Grasscutter commands
### Server console commands

`account create [username] {playerid}` - Creates an account with the specified username and the in-game uid for that account. The playerid parameter is optional and will be auto generated if not set.

### In-Game commands
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.

`!spawn [monster id] [level] [amount]`

`!give [item id] [amount]`

`!givechar [avatar id] [level]`

`!drop [item id] [amount]`

`!killall`

`!setworldlevel [level]` - Relog to see effects properly

`!godmode` - Prevents you from taking damage

`!resetconst` - Resets the constellation level on your current active character, will need to relog after using the command to see any changes.

`!sethp [hp]`

`!clearartifacts` - Deletes all unequipped and unlocked level 0 artifacts, **including yellow rarity ones** from your inventory

*More commands will be updated in the [wiki](https://github.com/Melledy/Grasscutter/wiki/).*

# Quick Troubleshooting
* If compiling wasn't successful, please check your JDK installation (must be JDK 8 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
