BooleanAND — logical AND

OR=BooleanOR, NOT=Not_PreBool, XOR=BooleanXOR

OR Boolean — logical OR of two booleans

NOT Boolean — logical NOT (invert boolean)

Component pattern: create Actor Component BP for reusable logic

CREATE: New Blueprint → parent class UActorComponent (or USceneComponent if needs transform). Add variables (Health, MaxHealth). Add EventBeginPlay (available in component). Add custom events/functions (TakeDamage, Heal, OnDeath). ADD TO ACTOR: In your Actor BP → Add Component → search for your component class. Or: SpawnActorFromClass → GetComponentByClass → CastTo<BP_HealthComponent>. CROSS-COMMUNICATION: In Component's OnDeath → GetOwner → CastTo<BP_Character> → call OnCharacterDied. Or: Component has Event Dispatcher 'OnDied' → owner binds to it. BENEFIT: Reuse HealthComponent on Enemy, Player, Vehicle without code duplication.

AND Boolean — logical AND of two booleans

Not_PreBool — logical NOT

Branch

Splits execution into True / False paths based on a Boolean condition. The most common decision node.

RandomBoolWithWeight — random bool with probability weight

Weight 0.0=always false, 1.0=always true, 0.5=50%.

Less (float) — A < B

Boolean

A True/False value. The simplest type — used for flags, toggles, and Branch conditions.
