Smooth zoom with mouse wheel on spring arm camera

Pattern: Variables TargetArmLength(float), MinZoom(float)=200, MaxZoom(float)=2000, ZoomStep(float)=50, ZoomSpeed(float)=5. InputAxis MouseWheel: TargetArmLength = FClamp(TargetArmLength - AxisValue*ZoomStep, MinZoom, MaxZoom). Tick: SpringArm.TargetArmLength = FInterpTo(Current, TargetArmLength, DeltaSeconds, ZoomSpeed). FInterpTo provides smooth easing.

MapRangeClamped — remap value from one range to another, clamped

Output clamped to OutRange. Use MapRangeUnclamped for unclamped version.

BreakTransform — split Transform into Location, Rotation, Scale

SetViewTargetWithBlend — smoothly blend camera to a new view target

BlendTime in seconds. BlendFunc: VTBlend_Linear, VTBlend_Cubic, VTBlend_EaseIn, VTBlend_EaseOut. Call on the PlayerController.

MapRangeUnclamped — remap value from one range to another, unclamped

string

AddMappingContext — add Enhanced Input mapping context to player

Get subsystem: GetSubsystem(UEnhancedInputLocalPlayerSubsystem, GetPlayerController(0)). Call in EventBeginPlay on the Character or PlayerController. Priority: higher number overrides lower number mappings.

Camera

Defines a viewpoint into the world. The active PlayerController's view comes from one camera at a time.

VSize — vector length magnitude

SetActorScale3D — set actor world scale

NOT K2_ prefixed (unlike SetActorLocation/Rotation).
