Smooth rotation toward a target location using RInterpTo on Tick

Pattern: EventTick → FindLookAtRotation(Start=GetActorLocation, Target=TargetLocation) → RInterpTo(Current=GetActorRotation, Target=LookAt, DeltaTime=DeltaSeconds, InterpSpeed=5.0) → SetActorRotation(NewRotation=InterpResult). Key pins: FindLookAtRotation inputs are 'Start' and 'Target' (both Vectors). RInterpTo inputs: 'Current' (Rotator), 'Target' (Rotator), 'DeltaTime' (float), 'InterpSpeed' (float). SetActorRotation input: 'NewRotation' (Rotator).

FindLookAtRotation — rotation from Start point looking at Target point

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

ApplyDamage — deal damage to a target actor

UGameplayStatics::ApplyDamage. Triggers EventAnyDamage on target.

FindLookAtRotation — get rotation to look from Start toward Target

FInterpTo_Constant — constant-speed interpolation toward target

Moves at constant speed unlike FInterpTo which decelerates.

SetSpringArmLength — set target arm length on spring arm component

USpringArmComponent property. Set directly or use SET node.

Cast target class doesn't exist or was deleted

Why: Your Cast To node references the class '{class}' which has been removed or renamed since you added the cast. Fix: Click the Cast To node. In Details panel, click the dropdown next to 'Cast To Class' and re-select the actual current class. If the class is truly gone, replace this Cast with an Interface call or a different type test.

ApplyPointDamage — deal point damage with hit info

GetTargetArmLength — get spring arm distance

Hit

A blocking collision between two shapes. Fires OnHit on both actors. Use for solid impacts.
