Unity Compile Error Fixer

Workflow

1. Unity_GetConsoleLogs (logTypes: "error") でエラーを取得
2. エラーコードとメッセージを分析
3. 該当ファイルを Read で確認
4. Edit で修正
5. Unity_GetConsoleLogs で修正確認
6. エラーが残っていれば 2 に戻る

Common Unity-Specific Errors

Error Code	Cause	Fix
CS0246	Type not found	Add using directive or assembly reference
CS1061	Member not found	Check Unity version API changes
CS0103	Name not in scope	Check namespace, add using
CS0234	Namespace member missing	Update package or add assembly reference
CS0029	Cannot convert type	Check Unity type casting (Vector3 vs Vector2)
CS0117	No member in type	API may have changed in Unity version
CS0619	Member is obsolete	Use recommended replacement
CS0428	Cannot convert method group	Add () for method call
CS0118	Namespace used as type	Use alias: using UIImage = UnityEngine.UI.Image;

Examples

Example 1: Missing namespace

error CS0246: The type or namespace name 'InputAction' could not be found

Fix: Add using UnityEngine.InputSystem;

Example 2: Old Input API

error CS0117: 'Input' does not contain a definition for 'GetKey'

Fix: Replace Input.GetKey(KeyCode.Space) with Keyboard.current.spaceKey.isPressed

Example 3: Deprecated API

warning CS0618: 'FindObjectOfType<T>()' is obsolete

Fix: Replace with FindFirstObjectByType<T>()

Example 4: Image namespace conflict (CS0118)

error CS0118: 'Image' is a namespace but is used like a type

Fix: Add alias using UIImage = UnityEngine.UI.Image; and use UIImage instead of Image

Troubleshooting

• エラーが消えない: .asmdef の参照が欠けている可能性。Assembly Definition を確認
• パッケージ関連エラー: Packages/manifest.json でパッケージバージョンを確認
• Unity バージョン差異: ProjectSettings/ProjectVersion.txt でバージョン確認
