Pull request overview

This PR updates the Unity UI Extensions package to support Unity 6, marking a major version bump from 2.3.3-pre.1 to 3.0.0-pre.1. The changes primarily involve removing version-specific conditional compilation directives and obsolete components that are no longer needed with Unity 6's requirement for TextMeshPro.

Key changes:

Updated minimum Unity version from 2020.3 to 6000.0 (Unity 6)
Added dependency on com.unity.ugui 2.0.0
Removed legacy Unity Text components in favor of TextMeshPro (TMP_Text)
Cleaned up obsolete version checks and conditional compilation directives
Removed deprecated text effects (NicerOutline, BestFitOutline, LetterSpacing, MonoSpacing, CylinderText, CurvedText)

Runtime/Scripts/ToolTips/ToolTip.cs:1

The error message is incomplete. It should specify 'Text' or 'TMP_Text component' instead of just ' component'.
Runtime/Scripts/Layout/UIVerticalScroller.cs:1
These new public properties expose internal fields without any validation or documentation. Consider adding XML documentation comments to explain their purpose and any constraints on their usage, especially since they allow external code to modify internal state.

Runtime/Scripts/Controls/ColorPicker/HexColorField.cs


            // Add listeners to keep text (and color) up to date
-            hexInputField.onEndEdit.AddListener(UpdateColor);
+            hexInputField.onValueChanged.AddListener(UpdateColor);


Changed from 'onEndEdit' to 'onValueChanged' which will cause UpdateColor to be called on every character typed, not just when editing is complete. This could impact performance and may cause unexpected behavior if color parsing fails on incomplete hex values.

Runtime/Scripts/Effects/CurlyUI/CUIText.cs

-#if UNITY_2022_1_OR_NEWER
-    [RequireComponent(typeof(TMPro.TMP_Text))]
-#else
    [RequireComponent(typeof(Text))]


This file still references the legacy 'Text' component instead of 'TMPro.TMP_Text', which is inconsistent with the rest of the PR where all Text components have been replaced with TextMeshPro. This should be updated to use TMP_Text for consistency with Unity 6 requirements.

Runtime/Scripts/Controls/ComboBox/ComboBox.cs

                _rectTransform = GetComponent<RectTransform>();
-                _inputRT = _rectTransform.Find("InputField").GetComponent<RectTransform>();
-                _mainInput = _inputRT.GetComponent<InputField>();
+                _mainInput = GetComponentInChildren<TMPro.TMP_InputField>();


If GetComponentInChildren returns null, the next line will throw a NullReferenceException. The original code had _inputRT set first, which would have caught this earlier. Consider adding a null check or reordering to validate _mainInput before using it.

Suggested change

_mainInput = GetComponentInChildren<TMPro.TMP_InputField>();

_mainInput = GetComponentInChildren<TMPro.TMP_InputField>();

if (_mainInput == null)

{

Debug.LogError("ComboBox: No TMP_InputField found in children. Please ensure a TMP_InputField is present.");

success = false;

return success;

Runtime/Scripts/Controls/TextPic.cs

+		protected void UpdateQuadImage()
+		{
+#if UNITY_EDITOR
+			if (UnityEditor.PrefabUtility.GetPrefabAssetType(this) == UnityEditor.PrefabAssetType.Regular)


Changed from checking PrefabType.Prefab to PrefabAssetType.Regular, which is the correct API for Unity 2018.3+. However, the condition logic might need review - the original code checked '!= Prefab' while this checks '== Regular', which may not be equivalent for all prefab types.

Suggested change

if (UnityEditor.PrefabUtility.GetPrefabAssetType(this) == UnityEditor.PrefabAssetType.Regular)

if (UnityEditor.PrefabUtility.GetPrefabAssetType(this) != UnityEditor.PrefabAssetType.NotAPrefab)
