SETUP (once per project): 1. Create Input Mapping Context (IMC_Default) in content browser. 2. Create Input Actions (IA_Move, IA_Jump, IA_Look) — set Value Type. 3. In IMC_Default, map keys to each IA. IN CHARACTER EventBeginPlay: GetController → CastTo<PlayerController> → GetSubsystem(UEnhancedInputLocalPlayerSubsystem) → AddMappingContext(IMC_Default, Priority=0). IN EVENT GRAPH: Right-click → search IA_Move → 'IA_Move (EnhancedInputAction)' node appears with Triggered/Started/Completed exec outputs and 'Action Value' data output. For 2D movement: IA_Move → GetAxis2D(ActionValue) → X to AddMovementInput(GetActorRightVector, ScaleValue=X), Y to AddMovementInput(GetActorForwardVector, ScaleValue=Y).

AddMappingContextUE 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoSetup: Create InputAction assets (IA_Move Axis2D, IA_Jump Digital). Create InputMappingContext (IMC_Default) mapping keys to IAs. BeginPlay: GetPlayerController → GetEnhancedInputLocalPlayerSubsystem → AddMappingContext(IMC_Default, 0). Bind: EnhancedInputAction IA_Move → Triggered pin → ActionValue → BreakVector2D → AddMovementInput.
string
Why: '{a}' includes '{b}' as a hard reference, AND '{b}' includes '{a}' as a hard reference. UE5 can't compile either one first without the other already being compiled. Fix: Break the cycle by making ONE side use a SOFT reference (TSoftObjectPtr). Pick the side that doesn't need {b} immediately at construction — change the variable type to 'Soft Object Reference' instead of 'Object Reference'. Use Load Asset to resolve it at runtime.
