Pattern: Pickup actor with SphereCollision(overlap), StaticMesh visual. OnComponentBeginOverlap → CastTo PlayerCharacter → Success: call AddScore/AddItem interface on player → PlaySoundAtLocation → SpawnEmitterAtLocation → DestroyActor(self). Set collision to OverlapOnlyPawn for performance.
Legacy Cascade system. Prefer Niagara (SpawnSystemAtLocation) for new projects.
SpawnEmitterAtLocationUE 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoUNiagaraFunctionLibrary::SpawnSystemAtLocation. bAutoDestroy=true for fire-and-forget. Use SpawnSystemAttached to attach to a component.
SpawnSystemAtLocationUE 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoK2Node_EnhancedInputAction. ActionValue type depends on InputAction (Bool, Float, Axis2D, Axis3D). Triggers: Started, Ongoing, Triggered, Completed, Canceled.
EnhancedInputActionUE 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoPattern: Variables bIsSprinting(bool), Stamina(float)=100, MaxStamina(float)=100, SprintSpeed(float)=1200, WalkSpeed(float)=600, DrainRate(float)=20, RecoverRate(float)=10. Sprint pressed: bIsSprinting=true → SetMaxWalkSpeed(SprintSpeed). Released: bIsSprinting=false → SetMaxWalkSpeed(WalkSpeed). Tick: Branch(bIsSprinting) → Stamina -= DrainRate*DT. Else: Stamina += RecoverRate*DT. Clamp(0, Max). If Stamina<=0 → force stop sprint.
The modern UE input system (5.0+). InputAction + InputMappingContext replace the legacy axis/action mappings.
Dealing damage: Event → ApplyDamage(TargetActor, BaseDamage, InstigatorController, DamageCauser, DamageTypeClass). Receiving: EventAnyDamage → Damage output → Subtract_FloatFloat(CurrentHealth, Damage) → FClamp(Result, 0, MaxHealth) → SET CurrentHealth → Branch(CurrentHealth <= 0) → True: DestroyActor. Initialize CurrentHealth=MaxHealth in BeginPlay.
UNiagaraFunctionLibrary::SpawnSystemAtLocation.
Spawn System at LocationUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoPattern: Variables CurrentWave(int)=0, EnemiesAlive(int)=0, EnemiesPerWave(Array<int>). StartWave: CurrentWave++ → SET EnemiesAlive=EnemiesPerWave[CurrentWave]. Timer looping: Branch(SpawnedThisWave < EnemiesPerWave[CurrentWave]) → SpawnActor(EnemyClass, RandomSpawnPoint) → SpawnedThisWave++. OnEnemyDeath: EnemiesAlive-- → Branch(EnemiesAlive <= 0) → StartNextWave or Victory.
UGameplayStatics::SpawnEmitterAtLocation. For Niagara, use SpawnSystemAtLocation.
