Advanced NPC Stealth & Patrol System for RPG Maker MZ

HI EVERYONE!!!

I created this plugin while working on a personal project using RPG Maker MZ. I found that the default pathing and battle logic were quite cumbersome, and most of the available plugins that could help were just too expensive. So, with some spare time and a tight budget, I decided to build my own solution.

This is my first plugin, so I’d love to hear your feedback. All comments are welcome!

I’ll do my best to keep improving it over time.

Features

• Path Patrolling: NPCs seamlessly patrol routes you define using Region IDs. They will loop through all tiles marked with the specified IDs, starting and ending at their initial position.
• Line of Sight Vision: NPCs detect the player only if they are within their frontal vision cone and range, with no obstacles (marked by a specific Region ID) blocking their sight.
• Automatic Chase: Upon spotting the player, NPCs will interrupt their patrol, adjust their speed (configurable), and pursue the player until they are caught or the player breaks line of sight and evades them.
• Dynamic Battle Outcomes:
  • Ambush (Surprise Attack): If an NPC catches the player from behind, the enemy party gets the first turn.
  • Preemptive Strike: If the player successfully approaches an unaware NPC and initiates contact, the player's party gets the first turn.
  • Normal Battle: Standard encounter initiation.
• Configurable NPC Behavior: Easily set up each NPC's parameters via a Plugin Command, including patrol regions, vision range, chase speed, chase memory duration, and more.
• Battle Customization: Define the troop ID for battles, whether the player can escape, and if the player can lose the battle (triggering a common event on loss instead of a game over).
• Post-Battle Self Switches: Automatically turn ON Self Switches (A, B, C, or D) based on whether the player wins, loses, or escapes the battle, allowing for easy event page progression.

How to Use

1. Download the YourPluginFileName.js file.
2. Place it in your RPG Maker MZ project's js/plugins/ folder.
3. Open the Plugin Manager in RPG Maker MZ, add the plugin, and turn it ON.
4. For any event you want to use this system with:
   • Set the event's Trigger to Parallel Process.
   • On the event's page, add the Plugin Command "Setup NPC Patrol/Stealth".
   • Configure the parameters within the Plugin Command to define the NPC's specific behavior.

Global Plugin Parameter:

• Vision Blocking Region ID: Set this once in the Plugin Manager parameters. This Region ID will act as a wall, blocking NPC line of sight.
