Reading a Uitext and Storing in Variable Unity
In this part, we'll get to know Variables in Unity'south Visual Scripting. In short, variables are containers that shop information and values.
A variable has a name, a type, and a value.
The value within a variable can modify throughout the game.
Imagine nosotros take a cookie jar and an envelope. The cookie jar can contain dissimilar kinds of cookies, exist information technology chocolate cookies or macaroons.
An envelope, on the other paw, may only comprise letters or postcards.
Every container can contain any value every bit long as it shares the aforementioned data type.
Therefore, nosotros tin can't put a cookie inside an envelope.
At any point, we can bank check which cookie is stored in the jar or supercede it with some other cookie.

Scopes
Each variable belongs to a unmarried Scope. We may want a variable to only be accessible to the electric current script graph, all scripts in the scene, or even remember its value after quitting the game.
In Unity's Visual Scripting, there are v kinds of Scopes:
Graph, Object, Scene, Application, and Saved.
Graph variables
Graph variables are local to the specific Script Graph. Therefore, they cannot be accessed or modified outside the script they are created in.
Object variables
Object variables are shared across all script graphs attached to a GameObject.
Notation that we can also edit Object variables in the GameObject Inspector.
Scene variables
Scene variables are shared beyond all the script graphs in the current scene.
Nosotros tin can also edit these telescopic variables in the Inspector of the 'Scene Variables' GameObject placed in the scene. This GameObject will exist created by Unity.
Awarding variables
Awarding variables are attainable from whatever script graph; their values remain even when the scene changes. However, they will reset once we quit the game.
Saved variables
Saved variables will persist fifty-fifty after nosotros quit and resume the game.
Why should we use a small-scale scope when 1 could apply a larger access scope, like the Awarding scope?
There may exist times when different objects volition have similar variables, for example, health points. All enemies will accept health points, but we demand to differentiate each enemy'southward health separately, co-ordinate to the damaged they have taken.
It tin be confusing at beginning. Merely over time, it will go evident which scope to use.
We often use the following avails and highly encourage y'all to check them out!
Creating a Variable
To add a variable, nosotros choose the relevant telescopic tab, name the variable, and press enter. Nosotros can now select the information blazon the variable will remember, then we will fill in an initial value.
Nether the Saved scope tab, we have Initial and Saved sub-tabs.
In the initial tab, we ascertain the values that will automatically be created for new games.
In the saved tab, we tin see the state of saved variables for our current calculator.
Set & Become
In the graph, we use the Become Variable node to get the information stored in it. This node gives the states the current value stored in the variable. Searching it at the Fuzzy Finder volition present u.s. with unlike scopes to select from. We tin can also change the scope at the nodes themself.
We get our variable by either typing its proper name or selecting it from the list.
In this example, I have continued the Go Variable node to a Debug Log node, which will print the variable'southward value to the console.
We can besides change a variable's value at any fourth dimension by using the Ready Variable node.
In this instance, I have created a Scene variable that remembers a boolean information type and set it to false.
Next up, we'll discuss working with loops & collections.
