Get Value as Enum
Welcome to the new Unreal Engine 4 Documentation site! We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready
Get Value as Vector. Target is Blackboard Component. Is Vector Value Set. If the vector value has been set (and not cleared), this function returns true (indicating that the value should be valid). If it's not set, the vector value is invalid and this function will return false.
Is Vector Value Set. If the vector value has been set (and not cleared), this function returns true (indicating that the value should be valid). If it's not set, the vector value is invalid and this function will return false. (Also returns false if the key specified does not hold a vector.) Target is Blackboard Component.
Enums basically give you ability to define a series of related types with long human-readible names, using a low-cost data type. These could be AI states, object types, ammo types, weapon types, tree types, or anything really :) Enumgraph.jpg.
For BP Graphs, one of the most wonderful things about ENUMS is the ability to use Switch on Enum () instead of having to do a series of branches and testing one value many times
What is an Enum? An Enum (also known as Enumeration) is used to give names to integer values. For example, a basic game menu state can be represented as names and programmed as integer numbers. All game engines can use enums as they are a basic programming feature. Unreal engine can use enums in c++ and blueprints.
