Drag-to-Move/Attack Fix ✅

Problem Identified

The drag-to-move/attack functionality was broken because the BattleActionIntegration system was enabled with useNewActionSystem = true by default, which was disabling the PlayerDecisionController that handles the drag input.

Root Cause

In BattleActionIntegration.cs, line 540:

playerDecisionController.enabled = !useNewActionSystem;

When useNewActionSystem was true, this line was setting playerDecisionController.enabled = false, completely disabling the drag input system.

Fix Applied

1. Changed Default System

• Before: useNewActionSystem = true (new action wheel system)
• After: useNewActionSystem = false (classic drag system)

2. Added Toggle Functionality

• Toggle Key: Press T to switch between systems
• Visual Feedback: Console shows which system is active
• Improved State Management: Ensures PlayerDecisionController is properly enabled when switching

3. Enhanced User Experience

• Added tooltip to inspector explaining the setting
• Added clear debug messages indicating which system is active
• Ensured proper cleanup when switching systems

How the Systems Work

Old Drag System (Default)

• Click and drag from character to enemy = Attack
• Click and drag from character to empty space = Move
• Simple and direct - no additional UI needed

New Action Wheel System (Press T to toggle)

1. Click character to select
2. Press Q to open action wheel
3. Click action (Move, Attack, Use Item, etc.)
4. Drag to target (if targeting required)

Testing Instructions

Test the Fix

1. Load battle scene with test mode
2. Verify current system: Should see "Old Click-Drag" in console
3. Test drag functionality:
   • Click and drag from player character to enemy (should attack)
   • Click and drag from player character to empty space (should move)

Test System Toggle

1. Press T to toggle to new system
2. Console should show: "New Action Wheel" message
3. Test new system:
   • Click character
   • Press Q for action wheel
   • Select action
   • Drag to target

Switch Back

1. Press T again to return to old system
2. Test drag functionality works again

Files Modified

• Assets/Scripts/BattleScene/BattleActionIntegration.cs
  • Changed useNewActionSystem default to false
  • Added toggle key functionality
  • Improved state management in ToggleActionSystem()
  • Enhanced debug messaging

Benefits of This Fix
