Priority: Secondary / Post-MVP
Labels: enhancement, input, secondary

Summary

Configure Unity's New Input System to support 2 local gamepads simultaneously and bind fundamental gameplay controls (Grid Selector, Confirm/Interact, Cancel/Back, End Turn, Hand Navigation).

Tasks

• Ensure Unity's Input System package is installed and active.
• Create an InputActions asset with basic action maps:
  • Maps (Vector2 / D-Pad & Left Stick)
  • Submit / Select (South Button / A)
  • Cancel / Back (East Button / B)
  • End Turn (North Button / Y or Menu Button)
  • Cycle Cards (Shoulder Buttons / LB & RB)
• Configure PlayerInputManager in the scene set to Join Players Manually or Local Co-op.
• Assign Gamepad 1 to Player 1 and Gamepad 2 to Player 2 upon game start.

Acceptance Criteria

• Connecting two gamepads registers Gamepad 1 and Gamepad 2 independently.
• Player 1 inputs only trigger actions during Player 1's turn.
• Player 2 inputs only trigger actions during Player 2's turn.
