How Can I Access Variables from One C# Script in Unity to Another?

Access variables of other scripts in C#

In Unity development, it is often necessary to access variables in different scripts. Here's a guide to achieving this:

Get the script component:

To access a variable in another script, you first need to get the script component itself. If the script is in a different game object, you must pass the game object as a reference in the inspector.

Sample code:

Consider two scripts: scriptA contains a public variable X, and scriptB needs to access X.

scriptA.cs

<code class="language-c#">public bool X = false;</code>

scriptB.cs

<code class="language-c#">public GameObject a; // 游戏对象A的引用
public scriptA script; // scriptA的容器

void Start()
{
    // 从游戏对象A获取脚本组件
    script = a.GetComponent<scriptA>(); 
}

void Update()
{
    // 访问并修改变量
    script.X = true;
}</code>

Update variable value:

To update the value of a variable from another script, just assign it a value in the Update function. In the above example, script.X is set to true in scriptB's Update function.

Other instructions:

• Make sure the variables you want to access are marked public in the script component.
• If you need to access variables in multiple other scripts, consider using shared variable scripts to avoid code duplication.
