Two goals, four anti-flap configurations. Watch flap appear and disappear with each toggle. Drop-in C++ actor.

[ Example ]

Patrol / Chase — anti-flap A/B

AIntentForgePatrolChaseExample is the framework's showcase for the five-layer Anti-Flap Toolkit. An agent oscillates between Patrol and Chase based on player distance. Without anti-flap protection it visibly stutters every time the distance crosses the trigger threshold. This is the example that converts skeptics: the framework's core differentiator turned on and off in real-time.

The four toggle configurations

Each toggle maps to a distinct anti-flap configuration. Walk through all four and watch flap disappear layer-by-layer.

`bEnableFactFiltering`	`bEnableLatchedBool`	What it demonstrates
`false`	`false`	No anti-flap (baseline) — direct `PlayerNear` from raw distance. Flaps visibly near the threshold.
`true`	`false`	Family 4 only — EMA filter smooths distance; threshold still on raw output.
`false`	`true`	Family 2 only — Schmitt latch on the raw distance; hysteresis band prevents flap.
`true`	`true`	Families 2 + 4 — filter feeds latch; the recommended default.

How to use it

Drop an Intent Forge Patrol/Chase Example actor in a level.

Place a pawn (Editor → Pawn or PlayerStart) within ~1000 units.

In the actor's Details panel under Intent Forge | Anti-Flap, start with both toggles false and set Goal Momentum Bonus to 0 for the cleanest baseline.

Hit Play. Move the player (WASD) around the trigger threshold (NearThreshold default = 500u). You'll see the agent flap between Patrol and Chase every replan.

Stop, enable Goal Momentum Bonus = 0.15 (Family 1, selection layer). Replay. Flap reduces.

Stop, enable bEnableLatchedBool = true (Family 2). Replay. Flap essentially disappears — the Schmitt band absorbs the noise.

Stop, enable bEnableFactFiltering = true (Family 4). The filtered value now feeds the latch — combined treatment.

Which families are demonstrated

Goal Momentum Bonus → Family 1 (score-domain biasing). Lives in the planner's goal scoring pass.
Latched Bool → Family 2 (latched fact derivation). Lives in FWorldState::SetScalar, runs on the way into the world state.
Fact Filtering → Family 4 (signal smoothing). EMA filter, also in the fact-derivation layer.

Family 3 (commit time floor) and Family 5 (structural plan reuse) are also live but harder to A/B in a single actor without a more elaborate scenario.

The implementation also ships a tiny UPatrolChaseBoolConsideration (goal scoring) and UPatrolChaseDistanceSensor (custom sensor) — good references for Cookbook recipes 20 and 21.
