UserId

Custom Attribute

UserId is a dynamic Attribute — instead of hardcoding a player's ID, you can use keywords that UiUtils resolves automatically at runtime.

Overview

The UserId Attribute is used by several Methods (like Avatar and Username) to identify which player to target. It accepts both static values and dynamic keywords.

Accepted Values

Value Type What it resolves to
12345678 Number Uses that exact UserId directly
LocalPlayer String The current player's UserId
Random String A random player's UserId from the server

Invalid values

If you type a string that isn't LocalPlayer or Random and isn't a number, UiUtils will show a warning in the Output and fall back to a random player's UserId.

Usage

Add a UserId Attribute on any UI instance that uses a Method requiring it:

  1. Select your UI instance in Roblox Studio
  2. In the Properties panel, scroll down to Attributes
  3. Click +, name it UserId, set the type to String or Number
  4. Set one of the accepted values above

Examples

Show the local player's avatar:

  • Attribute Method = Avatar
  • Attribute UserId = LocalPlayer

Show a specific player's username:

  • Attribute Method = Username
  • Attribute UserId = 12345678

Show a random player's avatar:

  • Attribute Method = Avatar
  • Attribute UserId = Random
