Your NPCs remember what the player did, and feel something about it. Remembrance gives agents episodic memories of events, people and places, and emotions attached to them - so the guard who watched you rob the till treats you differently tomorrow, and the villager you saved never forgets it.

• Do you want NPCs that remember important events and act on them later?

• Do you want NPCs that stop feeling like NPCs?

• Do you want them to love the player, or hold a grudge and follow them to the other end of your world?

• Do you want their feelings to shift based on what the player does and what happens around them?

• Do you want them to forget an old fear when something bigger happens, or remember one moment forever?

If any of those is a yes, this is for you.

What you get

Memories carry a start and end time, an initiator, a target, gameplay tags and an action id, and they fade on their own - or never, if you mark them everlasting. Query them by tag query, by who was involved, by what happened, or by how long ago it was. Emotions come in two flavours: general moods the agent carries (fear, anger, contentment) and emotions felt toward a specific actor or object, all normalized and ready to read. Everything is exposed to Blueprints and C++, with visual logger and gameplay debugger integration for seeing why an NPC feels what it feels.

Reputation systems, witnesses and crime, friendship and rivalry, trauma and grudges, social simulation, immersive sims and RPG companions - this is the layer under all of them.

Works with what you already use

Fully usable from Behavior Trees and State Trees. With Wise Feline Utility AI it needs no glue code at all: four built-in considerations score directly off memories and emotions - how strong a mood is, how the agent feels about its current target, how long ago something happened, and how many matching things it remembers. Pairs naturally with Influence Maps for agents that remember where things happened too.
