Unified Logic - Movements

ULM (Unified Logic — Movements) is an MZ plugin that unifies player input handling, A* pathfinding (with diagonal movement and wall‑sliding), runtime path overlay visualization, event pathing AI, and basic gamepad connection handling. Designed to integrate under a single Unified namespace (Unified.Pathfinding, Unified.Gamepad) and intended to sit below UnifiedSpriteSystem (USS)if using both in the plugin manager.

This is a stand alone plugin or works in unified connection with USS.

Key features

• Runtime input mode toggle (WASD ↔ Arrows) with a customizable toggle key.
• Smart A* pathfinding with diagonal moves and wall sliding.
• Nearest-reachable fallback if the target tile is blocked.
• Tile-based overlay visualization of the computed path (runtime toggle with \).
• Unified event pathfinding and chase behavior (near vs far logic).
• Basic gamepad connect/disconnect handling:
  • Pauses the game loop and shows a disconnect message window on controller disconnect.
  • Clears overlay and outstanding path queue on disconnect.
  • Resumes if a controller reconnects or keyboard/mouse input is detected.
  • Hides the mouse cursor while the controller is active and restores it on disconnect. 
• All logic lives under the Unified namespace to reduce global collisions and other plugin stack issues.

How the pathfinding works 

• When you set a destination (mouse click / touch), the player will compute an A* path to a nearest passable tile if the destination is blocked.
• The pathfinding allows diagonal moves and performs checks to ensure diagonal movement doesn't illegally squeeze through walls (it respects cardinal blocking unless wall‑sliding helper is present on the character).

• Overlay visualization is updated whenever the path is recalculated or consumed.
