AI Horror Enemy Toolkit (AIHET)

AI Horror Enemy Toolkit is a reusable single-file enemy AI controller for Unity built for horror, stealth, and tension-heavy gameplay. The system focuses on believable behavior rather than cheating or using perfect information. The AI uses cone-based sight, sound detection, memory of last known target information, suspicion escalation, investigation, patrol, search routines, blind chase, close-range reacquire, and optional experimental prediction and intercept behavior. It is designed to feel more human, readable, and responsive during pursuit. The asset includes a custom inspector with grouped controls, runtime debug tools, configurable state tuning, and UnityEvents for common gameplay hooks. It works well for developers who want either a simple drop-in enemy or a more advanced hunter-style pursuer with expandable behavior.
