4.5 Global Values

Global Value System

The Dialog backend comes with a Global Value System, giving you a bunch of Variables you can define by Name.

Variable Types

Supported Data Types

Integer Integer64 Float (Double) String Name Vector Vector2D IntPoint Boolean GameplayTag Actor-Reference

Setter and Getter

Each Variable comes with a Setter and a Getter Function.

You are able to set and get the values of your Globals within any Blueprint by calling the corresponding function of the Blueprint Function Libraries.

Configuration & Usage

Context	Description
Project Settings	You can define and set default values in the project Settings. These are loaded on Subsystem Startup. The System also offers a Function to Get and Set a whole Structure of all GlobalValues, useful for Saving to and Loading from a SaveGame Slot.
In Dialogues	GlobalValues are essential for handling Dialog Flow: Branch Node: Compares GlobalValues against each other. Event Node: Returns a specific collection of values to Event receivers. Beacon Node: Creates or modifies GlobalValues during the Dialog Flow. Messages: Using Message Replacement-Tags, you can replace text with the actual value of a variable.

Int to Float and String?! (Conversion)

Visual	Description
	To convert a GlobalValue from type A into Type B, you can use the predefined Subsystem function: ConvertGlobalValue This function lets you convert all valid variables (except for Actor References) into another type. This can also be done automatically by the Beacon Node inside a Dialog.
