Perception Extensions for Game Creator 2

This module requires Unity 6 and Game Creator 2 and Perception in order to work.

This module extends Game Creator 2 Perception with new Visual Scripting tools designed for stealth, action, horror, and tactical AI systems.

It adds a wide range of custom Triggers, Conditions, Instructions, and Properties for awareness control, target loss and reacquisition, suspicion states, investigation flow, last known positions, hearing logic, shared alarm behavior, and runtime perception utilities.

The package is built for designers who want more control over NPC sensing and reactions without modifying the original Game Creator 2 Perception module. It helps create richer behaviors such as searching lost targets, reacting to recent noise, sharing targets between nearby agents, controlling alert states, and driving stealth gameplay with more nuanced perception logic.

Key use cases include:

• Stealth AI with suspicion, alert, and combat detection states
• Investigation and search behavior based on evidence or positions
• Last known position logic for pursuit and search sequences
• Noise-based reactions and hearing memory
• Group alarm and target sharing between nearby NPCs
• Utility instructions for forcing refreshes, clearing memory, and adjusting detection behavior
