Text.fontSize

描述

Font 渲染时应使用的大小。

这是 Text 的 Font 的大小。可用于提取或更改 Font 的大小。更改 Font 的大小时，请记得考虑 Text 的 RectTransform。过大的 Font 或过长的消息可能不适合某些矩形的大小，无法在 Scene 中显示。

//For this script to work, create a new Text GameObject by going to Create>UI>Text. Attach the script to the Text GameObject. Make sure the GameObject has a RectTransform component.

using UnityEngine.UI;

public class Example : MonoBehaviour
{
    Text m_Text;
    RectTransform m_RectTransform;

    void Start()
    {
        //Fetch the Text and RectTransform components from the GameObject
        m_Text = GetComponent<Text>();
        m_RectTransform = GetComponent<RectTransform>();
    }

    void Update()
    {
        //Press the space key to change the Font size
        if (Input.GetKey(KeyCode.Space))
        {
            changeFontSize();
        }
    }

    void changeFontSize()
    {
        //Change the Font Size to 16
        m_Text.fontSize = 30;

        //Change the RectTransform size to allow larger fonts and sentences
        m_RectTransform.sizeDelta = new Vector2(m_Text.fontSize * 10, 100);

        //Change the m_Text text to the message below
        m_Text.text = "I changed my Font size!";
    }
