如何分配GameObject的x和y位置? [英] How do I assign a GameObject's x and y position?

问题描述

我正在统一创建一个视频游戏，对于关卡选择，我需要将GameObject的x和y位置设置为按钮的x和y位置.

I am creating a video game in unity, and for the level select, I need to set the x and y position of a GameObject to the x and y position of a button.

我已经尝试过此代码-

if (gameObject.CompareTag("Level1")) {

        float xPos = gameObject.transform.position.x;
        float yPos = gameObject.transform.position.y;

        levelWindow.SetActive(true);
        levelTitle.text = "One- Dunes of Coral";
        levelDescription.text = "Begin your ocean voyage in the safe haven of the Hawaiian coral reefs...";
        levelWindow.transform.position.x = xPos;
        levelWindow.transform.position.y = yPos;
}

但是我收到这样的错误-

But I get an error like this-

资产/脚本/LevelTapScript.cs(21,39):错误CS1612:无法修改"UnityEngine.Transform.position"的值类型返回值.考虑将值存储在临时变量中

Assets/Scripts/LevelTapScript.cs(21,39): error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.position'. Consider storing the value in a temporary variable

我的问题是如何使用我的xPos和yPos浮点数设置levelWindow(这是一个游戏对象)的x和y位置?谢谢，乔治:)

My question is how do I set the x and y position of the levelWindow (which is a game object) using my xPos and yPos floats? Thanks- George :)

推荐答案

您必须创建一个临时Vector3变量，修改x轴，然后将其分配回Transform.position.

You have to create a temporary Vector3 variable, modify the x axis then assign it back to the Transform.position.

    if (gameObject.CompareTag("Level1"))
    {

        float xPos = gameObject.transform.position.x;
        float yPos = gameObject.transform.position.y;

        Vector3 newPos = new Vector3(xPos,yPos,0);

        levelWindow.SetActive(true);
        levelTitle.text = "One- Dunes of Coral";
        levelDescription.text = "Begin your ocean voyage in the safe haven of the Hawaiian coral reefs...";
        levelWindow.transform.position = newPos;
        levelWindow.transform.position = newPos;
    }

请注意，执行此操作时z pos将为0.

Note that z pos will be 0 when you do this.
