Welcome to EU-Utility V3

+

+ This setup wizard will help you configure the application to read + screen elements from Entropia Universe. This enables features like + automatic loot tracking, HP monitoring, and skill gain detection. +

+
+ +
+

What will be configured:

+
    +
  • + + HP bar position and reading +
    • +
  • + + Radar/mini-map coordinate extraction +
    • +
  • + + Skill window detection +
    • +
  • + + Mob name recognition +
    • +
+
+
+ )} + + {step === 1 && ( +

Auto-Detect UI Elements

+

+ Make sure Entropia Universe is running and visible on your screen, + then click detect to automatically find UI elements. +
