WASD character movement using AddMovementInput with input axis events

Pattern: InputAxis MoveForward → Multiply_FloatFloat(A=AxisValue, B=1.0) → AddMovementInput(WorldDirection=GetActorForwardVector, ScaleValue=Product). Repeat for MoveRight with GetActorRightVector. Key pins: AddMovementInput inputs: 'WorldDirection' (Vector) and 'ScaleValue' (float). Input Axis event output pin is named 'Axis Value' (float).

WasInputKeyJustPressed — true only on the frame the key was pressed

BooleanAND — logical AND

OR=BooleanOR, NOT=Not_PreBool, XOR=BooleanXOR

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.

IsInAir (IsFalling) — true if character is in the air

Call on the CharacterMovementComponent, not directly on Character. Or use IsMovingOnGround.

Texture2D

A 2D image asset used by Materials (color, normal, roughness maps) or UMG Images.

Sublevel

A child level streamed in/out of a persistent level. Used for open-world streaming and modular maps.

Not_PreBool — logical NOT

FMod — floating point modulus remainder

RandomUnitVector — random direction unit vector
