Custom Commands (Blueprint)

Register your own commands. They get permission checks, aliases and usage help, show up in /help, and work from chat, the server console and Execute Command.

Registering a command

Register commands on the server, for example in your Game Mode's Begin Play:

1. Get Server Core
2. Register Command
   • Info: make a ServerCore Command Info
     • Name: heal
     • Aliases: h
     • Permission: mygame.heal
     • Usage: <player>
     • Description: Heals a player to full health.
     • Min Args: 1
   • Handler: Create Event → a function with the signature (Caller, Args) → String

The handler receives:

Input	Description
Caller	Who ran the command. Use it for further permission checks or logging.
Args	The arguments without the command name. Quoted text is one argument.

Return a string. It is sent back to whoever ran the command (multiple lines are fine).

Function HandleHeal (Caller, Args) → String
 ├─ Get Server Core → Find Player (Args[0], Include Offline = false)
 │    ├─ false → return Error
 │    └─ true  → Get Player Controller (Player Id) → Get Pawn → heal
 └─ return "Healed " + Player Name

note

Commands registered with the same name as an existing command replace it. You can use this to override a built-in command. Remove a command with Unregister Command.

Permissions

Give the permission to a group:

/groupperm Moderator add mygame.heal

An empty Permission means everyone can run the command.
