LGUI (Lex GUI) - Powerful Component based 3D UI System, Event Framework, Prefab Workflow, Tween Animation.
Component based UI creation workflow!



Next version released ---- LGUI3

(CAUTION) LGUI3 is not fully compatible with LGUI2, follow this video to upgrade your project to LGUI3: Youtube Bilibili , but I can't guarantee this convertion is good for every project.
UE5 support is in progress: Youtube Bilibili
Changes in LGUI3:
  • Coornidate system: from Unity-like (x-right, y-up, z-forward) to UE-like (x-forward, y-right, z-up) coordinate system.
  • Color property: UIItem.Widget.Color moved to UIBaseRenderable.Color.
  • UICanvasGroup: Handle children UI element's opacity and interactable.
  • Anchor system: LGUI3 use AnchorMin/AnchorMax/AnchoredPosition/SizeDelta anchor system, just like Unity's, clean and predictable.
  • Name redirect: eg. LGUIDrawableEvent to LGUIEventDelegate, AwakeBP to ReceiveAwake, StartBP to ReceiveStart, XXXBP to ReceiveXXX. Blueprint can automatic convert with no extral work, C++ can check LGUI/Config/DefaultLGUI.ini to see all these changes.
New Features in LGUI3:
  • Use hierarchy order for UI element's render order, no noring "Depth" property anymore.
  • Prefab workflow upgrade: Standalone prefab editor, support nested prefab, support property redirect, faster load speed.
