此 Text 显示的/字符串/值。

使用此设置可读取或编辑 Text 中显示的消息。使用其他 Text 属性，如 size、font 和 alignment，可更改 text 的外观。在此示例中，这些属性将更改 text：

using UnityEngine;
using UnityEngine.UI;

// UI.Text.text example
//
// A Space keypress changes the message shown on the screen.
// Two messages are used.
//
// Inside Awake a Canvas and Text are created.

public class Example : MonoBehaviour
{
    private enum UpDown { Down = -1, Start = 0, Up = 1 };
    private Text text;
    private UpDown textChanged = UpDown.Start;

    void Awake()
    {
        // Load the Arial font from the Unity Resources folder.
        Font arial;
        arial = (Font)Resources.GetBuiltinResource(typeof(Font), "Arial.ttf");

        // Create Canvas GameObject.
        GameObject canvasGO = new GameObject();
        canvasGO.name = "Canvas";
        canvasGO.AddComponent<Canvas>();
        canvasGO.AddComponent<CanvasScaler>();
        canvasGO.AddComponent<GraphicRaycaster>();

        // Get canvas from the GameObject.
        Canvas canvas;
        canvas = canvasGO.GetComponent<Canvas>();
        canvas.renderMode = RenderMode.ScreenSpaceOverlay;

        // Create the Text GameObject.
        GameObject textGO = new GameObject();
        textGO.transform.parent = canvasGO.transform;
        textGO.AddComponent<Text>();

        // Set Text component properties.
        text = textGO.GetComponent<Text>();
        text.font = arial;
        text.text = "Press space key";
        text.fontSize = 48;
        text.alignment = TextAnchor.MiddleCenter;

        // Provide Text position and size using RectTransform.
        RectTransform rectTransform;
        rectTransform = text.GetComponent<RectTransform>();
        rectTransform.localPosition = new Vector3(0, 0, 0);
        rectTransform.sizeDelta = new Vector2(600, 200);
    }

    void Update()
    {
        // Press the space key to change the Text message.
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (textChanged != UpDown.Down)
            {
                text.text = "Text changed";
                textChanged = UpDown.Down;
            }
            else
            {
                text.text = "Text changed back";
                textChanged = UpDown.Up;
            }
        }
    }
}
