Working with a game client

Clients, resources and other files for loading the launcher are stored in the form of subdivorories in the UPDATES directory, and the profiles that indicate the name of the Directory, the address of the server for the car driver, exclusion during updating and other information necessary for launching the client are stored in the Profiles Directory

Supported versions

At the moment, the launcher can run all versions from 1.7.10 according to the current version of Minecraft, except for Forge +1.17.1

Client installation

Stem 1: Add to ours mirroropen in new window to the launch server config and restart it

"mirrors": [ 
  "https://mirror.gravit-launcher.ru/"
],

Stem 2: Follow the next command to download the client

downloadclient <version> <name>

version - This is a version of Minecraft. Currently, we are dividing versions into 3 types:

1.16.5 - Vanilla minecraft
1.16.5-forge - Minecraft modified Forge
1.16.5-fabric - Minecraft modified Fabric

name - Client's name for your choice

Step 3(Optional): Perform the next command for downloading ascets (textures, sounds, etc.) of the client

downloadclient <version> asset<version>

After these actions, the client downloads in the updates folder and a profile will be created in the profiles folder

Client profile configuration

Example configuration

After downloading the client, the launa server will automatically create a profile and fill it with the basic data. The following is an example of a finished configuration for Minecraft 1.17.1

Synchronization

To ensure high performance, the launcher ceremer caching the contents of the UPDATES and Profiles directory.When making changes to these directors, the launa server is not aware of them, and at the next update there will most likely be an error.In order to synchronize the contents of these directors, there are two teams - syncupdates and syncprofiles:

syncupdates # Synchronizes the contents of the Updates directory
syncprofiles # Synchronizes the contents of the Profiles directory
syncup # Synchronize both directors
