Variables

Description

Variables are, by definition, data structures holding a specific value that can be edited during runtime.

Each variable is defined by its name, type, and scope inside OverScriptManager and OverScript.

In general, variables can be distinguished into two main categories:

• GLOBAL: Variables having the widest scope possible, that can be accessed by every script in a Scene. OverScriptManager is responsible for handling global variables and it is the only place in which they can be defined

• LOCAL: Variables that have their scope limited only to a specific OverScript, in which they are defined and reside. Local variables cannot be referenced by a different script.

Handling variables

Once a variable is correctly defined, a variable is listed in the Graph. A variable can be presented in two kinds of nodes, depending on its usage:

• GET Node: a Plain Node whose purpose is to deliver the current value of the variable.

• SET Node: a Flow Node whose purpose is to edit the value of the variable.

A variable may be defined for any type of object. It is therefore possible, thanks to variables, to interact with any component associated with objects in the scene.
