Event UI
by elyisus_xd
Event UI is a Fabric client mod that draws quest and event screens sent by a server, with missions, progress bars and a HUD tracker that the server plugin fills in.
What it does
Servers define their quest interface with simple YAML files, and the client renders it using textures, buttons, backgrounds and icons the author uploads. Screens can branch into submenus with multi-screen navigation, and items and text can carry tooltips with hover effects. Two modes are available in config.yml: a default predefined layout with scrolling mini-navigation, categories and filters, and a custom mode where the screens are designed entirely from YAML.
Missions cover mining blocks, killing mobs, crafting items, exploring biomes, visiting dimensions, reaching XP levels, using enchantments and completing custom goals. Events can stay hidden until prerequisites are met, and objectives can be sequential, parallel or weighted. Event UI requires Event UI Plugin on the server, and without that plugin the mod has nothing to display. Event UI is client-side only, so players install it while servers run the plugin. Files target 1.21.1 – 1.21.3 on Fabric, released under the MIT License as open source.
