class Classes (42)

AActor BP The base class for all actors that can be placed or spawned in the world. ACharacter BP ACharacter extends APawn with a CapsuleComponent for collision, a SkeletalMeshComponent for visual representation, and a CharacterMovementComponent for walking, running, jumping, swimming, and flying. AGameModeBase Server-only actor that defines the rules of the game: which pawn class to spawn, how players log in and respawn, and game flow. AGameStateBase Replicated actor that holds authoritative game state visible to all clients — the client-accessible counterpart to `AGameModeBase`. APawn BP APawn is the base class for all actors that can be possessed and controlled by a PlayerController or an AIController. APlayerState BP Created for every player on a server (or in a standalone game) and replicated to all clients. FTimerManager Manages all gameplay timers for a UWorld instance. UActorComponent BP The base class for all actor components. UAnimInstance BP The runtime instance of an Animation Blueprint, responsible for evaluating the anim graph and driving a skeletal mesh. UAnimMontage BP An animation asset that sequences animation segments into named sections, supports blend in/out, and can be played, stopped, and jumped between sections at runtime via UAnimInstance. UAssetManager The engine singleton that manages primary asset discovery, async loading, bundle state, and chunked DLC. UAudioComponent BP A scene component that plays a USoundBase asset at the component's world location with full control over volume, pitch, 3D spatialization, fade transitions, and runtime parameters. UBlendSpace BP An animation asset that blends between multiple animation sequences based on one or two float parameters (e. UCameraComponent BP A component that defines a camera view. UCharacterMovementComponent BP The movement component used by ACharacter. UCurveFloat BP A curve asset that maps time (float) to a float value via keyframed spline data. UCurveLinearColor BP A curve asset with four channels (R, G, B, A) that returns an FLinearColor when evaluated. UCurveVector BP A curve asset with three float channels (X, Y, Z) that returns an FVector when evaluated. UDataAsset A simple UObject-derived asset that holds designer-authored data. UDataTable BP A spreadsheet-like asset that maps FName row keys to structs inheriting from FTableRowBase. UEngineSubsystem Subsystem base class that lives for the entire lifetime of `GEngine` — from engine startup to shutdown. UGameInstanceSubsystem Subsystem base class whose lifetime matches the `UGameInstance`. UGameplayStatics BP A Blueprint function library providing static utility functions for common gameplay operations: actor spawning, player access, damage, audio, level loading, and save games. ULocalPlayerSubsystem Subsystem base class scoped to a `ULocalPlayer`. UPrimaryDataAsset BP A data asset subclass that implements GetPrimaryAssetId, allowing it to be registered with UAssetManager for on-demand async loading, bundle management, and chunked DLC. UPrimitiveComponent BP The base class for all components that have a visual representation and can interact with the physics and collision systems. USaveGame BP Base class for save game objects. USceneComponent BP The base class for all components that have a position, rotation, and scale in the world. USkeletalMeshComponent BP A component that renders a skeletal mesh and drives it with animation. USoundAttenuation BP A data asset wrapping FSoundAttenuationSettings that controls how a sound's volume, spatialization, air absorption, reverb send, and occlusion change with listener distance. USoundBase BP The abstract base class for all playable sound assets. USoundClass BP A hierarchical category asset that groups sounds and applies shared volume, pitch, reverb, and submix routing. USoundCue BP A graph-based audio asset that combines SoundWaves with nodes for mixing, randomization, looping, pitch modulation, and sequencing. USoundMix BP Applies temporary volume, pitch, and EQ adjustments to specified SoundClasses when pushed to the audio device. USoundWave BP A raw audio asset imported from a WAV file. USplineComponent BP A component that defines a curved path through space using Hermite spline points. USplineMeshComponent BP A static mesh component that deforms its mesh along a local spline segment, stretching or bending it between two defined points. USpringArmComponent BP A component that maintains a fixed distance from its parent, retracting when obstructed by geometry and smoothly returning to its target length. UStaticMeshComponent BP A component that renders a static mesh asset. USubsystem Base class for all UE subsystems — auto-instanced singletons that share the lifetime of a specific engine construct (Engine, GameInstance, World, or LocalPlayer). UWorld BP The top-level game world object. UWorldSubsystem Subsystem base class tied to a single `UWorld` — created when the world initializes and destroyed when it tears down.

struct Structs (3)

FStreamableManager Manages asynchronous and synchronous loading of soft-referenced UObject assets. FTableRowBase The required base struct for all data table row types. FTimerHandle BP An opaque handle that uniquely identifies a timer managed by FTimerManager.

function Global Functions (110)

property Properties (5)

UCharacterMovementComponent::JumpZVelocity BP The instantaneous vertical velocity applied to the character when a jump begins. UCharacterMovementComponent::MaxWalkSpeed BP The maximum ground speed in cm/s when walking. UPrimitiveComponent::OnComponentBeginOverlap BP Delegate fired when another component begins overlapping this component. UPrimitiveComponent::OnComponentEndOverlap BP Delegate fired when a previously overlapping component stops overlapping. UPrimitiveComponent::OnComponentHit BP Delegate fired when this component physically hits another.
