从另一个脚本C#访问变量你能告诉我如何从另一个脚本访问脚本的变量吗?我甚至已经阅读了统一网站上的所有内容,但我仍然无法做到。我知道如何访问另一个对象而不是另一个变量。情况就是这样:我在脚本B中,我想X从脚本A访问变量。变量X是boolean。你能帮助我吗 ?顺便说一句,我需要X在脚本B中大幅更新其值,我该怎么做?在Update功能中访问它如果你可以给我和这些字母的例子将是伟大的!谢谢

首先需要获取变量的脚本组件,如果它们位于不同的游戏对象中,则需要将游戏对象作为参考传递给检查器。
例如,我scriptA.cs在GameObject A和scriptB.cs在GameObject B:
scriptA.cs
// make sure its type is public so you can access it later onpublic bool X = false;
scriptB.cs
public GameObject a; // you will need this if scriptB is in another GameObject
// if not, you can omit this
// you'll realize in the inspector a field GameObject will appear
// assign it just by dragging the game object therepublic scriptA script; // this will be the container of the scriptvoid Start(){
// first you need to get the script component from game object A
// getComponent can get any components, rigidbody, collider, etc from a game object
// giving it <scriptA> meaning you want to get a component with type scriptA
// note that if your script is not from another game object, you don't need "a."
// script = a.gameObject.getComponent<scriptA>(); <-- this is a bit wrong, thanks to user2320445 for spotting that
// don't need .gameObject because a itself is already a gameObject
script = a.getComponent<scriptA>();}void Update(){
// and you can access the variable like this
// even modifying it works
script.X = true;}

只是为了完成第一个答案
没有必要
a.gameObject.getComponent<scriptA>();
a已经是一个GameObject所以这样做了
a.getComponent<scriptA>();
如果您尝试访问的变量是GameObject您应该使用的子项
a.GetComponentInChildren<scriptA>();
如果您需要它的变量或方法,您可以像这样访问它
a.GetComponentInChildren<scriptA>().nameofyourvar;a.GetComponentInChildren<scriptA>().nameofyourmethod(Methodparams);

你可以在这里使用static。
这是一个例子:
ScriptA.cs
Class ScriptA : MonoBehaviour{
public static bool X = false;}ScriptB.cs
Class ScriptB : MonoBehaviour{
void Update() {
bool AccesingX = ScriptA.X;
// or you can do this also
ScriptA.X = true;
}}要么
ScriptA.cs
Class ScriptA : MonoBehaviour{//you are actually creating instance of this class to access variable.
public static ScriptA instance;
void Awake(){
// give reference to created object.
instance = this;
}
// by this way you can access non-static members also.
public bool X = false;}ScriptB.cs
Class ScriptB : MonoBehaviour{
void Update() {
bool AccesingX = ScriptA.instance.X;
// or you can do this also
ScriptA.instance.X = true;
}}有关更多详细信息,您可以参考singleton类。
