GetSocketLocation — get world location of a named socket on a mesh

Pure node. Socket must be defined in the skeletal mesh or added in the Editor.

Spawn projectile from socket location facing forward

Pattern: InputAction Fire → GetMesh → GetSocketTransform(InSocketName='MuzzleSocket') → BreakTransform(outputs Location, Rotation) → MakeTransform(Location=SocketLocation, Rotation=SocketRotation) → SpawnActorFromClass(Class=BP_Projectile, SpawnTransform=Transform). Key: GetSocketTransform must be called on the SkeletalMeshComponent (GetMesh()), not the actor. Use 'World' TransformSpace. SpawnActorFromClass takes a full Transform, not separate Location/Rotation.

GetSocketRotation — get world rotation of a socket on mesh component

GetSocketTransform — get world transform of a named socket

GetSocketLocation — get world location of a socket on mesh component

Wire connects two pins of incompatible types

Why: You wired a '{pinA}' output to a '{pinB}' input — UE5 doesn't know how to convert between them. The compiler refuses to insert an implicit cast for unsafe conversions. Fix: Right-click between the two nodes and look for a conversion node (e.g. ToString, Truncate, Cast To). If converting between Object types, use Cast To. For numeric conversions, use the dedicated converter nodes. If the conversion truly doesn't make sense, the wiring is logically wrong — re-check the design.

Wrong class plugged into a pin expecting a specific type

Why: A pin expected an actor of type '{expected}' (or subclass) but you connected a '{actor}' which doesn't inherit from it. Fix: Either: (a) change your '{actor}' to inherit from '{expected}' by reparenting it (File → Reparent Blueprint), or (b) use a Cast To node to verify the type at runtime, or (c) plug in a different actor that IS a subclass of '{expected}'.

Required input pin has no value wired to it

Why: The '{pin}' input on '{node}' must receive a value — either a wire from another node OR a default value in the pin field — but it's empty. Fix: Click on the '{pin}' input field on the '{node}' node. Either type a literal value (e.g. 5 for an integer), or drag a wire from another node's output. If you don't know what to connect, hover over the pin for a tooltip describing what it expects.
