Turn on and identity

The launcher is the app your players install to join the server, with your store's name and brand. It downloads the mods, sets up Java and opens the game on the right server. The store's plan defines whether it is included, how many builds per month, how many modpacks and how much space for mods.

Launcher: the published version, the limits and the settings screens

The path

Step	Screen	Needs a new installer?
1	Identity: name, icon and executable	Yes
2	Appearance: colors, logo, background and music	No
3	Modpacks: server, version and files. See Accounts and modpacks	No
4	Accounts & login: if the server uses its own login	No
5	Builds: build the installer. See Build the installer

App identity

In Launcher > Identity:

Field	What it is	Example
App name	What shows on the window and the Start menu. 3 to 40 characters	`Rede Pixel Launcher`
Bundle identifier	How the system tells your launcher from others	`com.redepixel.launcher`
Executable name	Lowercase, numbers and hyphens. It becomes the file name	`redepixel-launcher`
Channel	Stable or Beta. Whoever installed from one does not get updates from the other	`Stable`
Installer icon	Square PNG, at least 256x256

The icon can only be uploaded after saving the identity for the first time.

Players who already have the launcher get the change through auto-update, after you build a new installer.

Appearance

In Launcher > Appearance, the preview on the side shows how it looks. Nothing on this screen needs a build.

Background music: MP3 or OGG, up to 8 MB. The Initial volume is just the start: the player adjusts or turns it off in their settings.

Show server status	Players online and availability
Show server address	The IP shows on the home screen and the player copies it with one click
