从其他脚本访问变量 [英] Accessing variable from other script

问题描述

如何从其他脚本组件中调用变量?

How do I call a variable from other script components?

mirror.transform.position = cop.GetComponent("AI_Car").mirrorPos;

似乎无法访问在脚本AI-Car-script中声明的公共变量carPos:

It seems that the public variable carPos declared in the script AI-Car-script cannot be accessed:

'mirrorPos' is not a member of 'UnityEngine.Component'.

推荐答案

两件事:

1)我使用C#工作，所以我对此可能是错的，但是我认为您必须获取组件，然后获取变量.例如:

1) I work in C#, so I may be wrong about this, but I think you have to get the component and THEN get the variable. For example:

var otherScript: OtherScript = GetComponent("AI_CAR"); 
var newPosition = otherScript.mirrorPos; 

2)我认为最好的做法是先创建一个临时变量，然后再访问它.因此，在上面的示例中，我将像这样更改mirror.transform.position:

2) I think it's best practice to make a temporary variable and then access it. So in the above example, I would then change mirror.transform.position like this:

mirror.transform.position = newPosition;

显然，在vars中工作并不总是很好(有时是完全不同的对话)，但这只是一个简单的伪代码示例.希望这会有所帮助！

Obviously it's not not always great to work in vars (sometimes it is, that's an entirely different conversation) but this is just a simple pseudocode example. Hope this helps!
