FindLookAtRotation — get rotation to look from Start toward Target

ApplyPointDamage — deal point damage with hit info

FindLookAtRotation — rotation from Start point looking at Target point

Returns the Rotator needed to look from Start toward Target. Common for aiming and facing.

AddImpulse — apply instant impulse to physics body

One-shot force. bVelChange=true treats Impulse as velocity change.

AddForce — apply continuous force to physics body

Continuous force — apply every frame. Use AddImpulse for one-shot.

Physics Body

A SceneComponent with simulate-physics enabled. Driven by forces, gravity, collisions instead of explicit transforms.

Health and damage system with ApplyDamage and EventAnyDamage

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.

EnhancedInputAction — Enhanced Input system action event

K2Node_EnhancedInputAction. ActionValue type depends on InputAction (Bool, Float, Axis2D, Axis3D). Triggers: Started, Ongoing, Triggered, Completed, Canceled.

Delay — latent delay node pauses execution for Duration seconds

UKismetSystemLibrary::Delay. Latent node — only works in Event Graph, not functions. Output exec displays as Completed.

SetWorldLocation on component — set component world position

K2_SetWorldLocation. USceneComponent method.
