Variable node pin naming rules in UE5 Blueprints: - GetVariable: PURE node — NO exec pins. Single output pin named exactly after the variable (e.g. 'Health'). - SetVariable: exec in='execute', exec out='then'. Input pin named exactly after the variable (e.g. 'Health'). Output pin named exactly after the variable (returns new value). - Variable names ARE case-sensitive in connections. 'MyHealth' != 'myhealth'. - When connecting to SetVariable, the input pin name MUST match variable_name exactly.
Macro from StandardMacros. LastIndex is inclusive (uses <=).
ForLoopUE 5.4, 5.7updated 2mo agoInternal pin names: True path is 'then', False path is 'else'. Display names show True/False.
BranchUE 5.4, 5.7updated 2mo agoStandard addition. Works on Integer, Float, Vector, Rotator, etc — UE picks the right overload from pin types.
EventTick output pin is named DeltaSeconds (not DeltaTime). This is the time since last frame.
Event TickUE 5.4, 5.7updated 2mo agoK2Node_DynamicCast. Cast Failed pin name is CastFailed. As output pin is dynamically named.
CastToUE 5.4, 5.7updated 2mo agoWhy: 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}'.
K2Node_SpawnActorFromClass. Class pin is a class reference dropdown.
SpawnActorFromClassUE 5.4, 5.7updated 2mo agoAdd more output pins as needed. Pin names: Then 0, Then 1, etc.
SequenceUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoA case-insensitive immutable string ID. Fast comparisons; used for tags, slot names, asset references.
