Enhanced Input BindAction — bind an Input Action to a Blueprint function (UE5 new input)

UE5 Enhanced Input replaces legacy BindAxis/BindAction. In BP: use 'Enhanced Action Events' category nodes (IA_ nodes appear automatically). ETriggerEvent: Started (pressed), Triggered (held), Completed (released). Input Action outputs: 'Action Value' (InputActionValue struct) and typed output.

Latent Action

A node that doesn't return immediately — Delay, MoveTo, etc. Execution suspends until the action completes.

Enhanced Input Action asset is missing

Why: A node references the InputAction '{ia}' which was deleted, renamed, or never created. The compiler can't bind to it. Fix: In Content Browser, search for '{ia}'. If found: re-link the node by dropping it on the workspace + replacing the broken reference. If missing: create the InputAction (Content Browser → right-click → Input → Input Action), then add it to your InputMappingContext.

EnhancedInputAction — Enhanced Input system action event

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

StopJumping — stop the jump action

Projectile actor that moves forward and deals damage on hit

Pattern: BP_Projectile with SphereCollision(root), StaticMesh, ProjectileMovementComponent(InitialSpeed=3000, MaxSpeed=3000, bRotationFollowsVelocity=true). OnComponentHit → ApplyDamage(OtherActor, Damage, GetInstigatorController, Self) → SpawnEmitterAtLocation(ImpactPoint) → DestroyActor. Spawner: SpawnActorFromClass(BP_Projectile, MuzzleLocation, MuzzleRotation).

EventHit — fires when actor is hit by or hits something

Requires Simulation Generates Hit Events on physics body.

InputAction

A reusable input definition (Jump, Attack, Look). Pure data — bind it to keys via an InputMappingContext.

Hit

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

AddActorWorldOffset — move actor by world-space delta
