Unity a tool: display text to the screen

Work projects we often use the wrong cue to the success of the show to be more advantageous for the player to watch and understand on the screen, this time we need the operation is to send what we need to be displayed on the display screen, and then implement text content, as shown below:

Achieve this we need two scripts contents of a Text and display text reads:

Text in ugui above components are as follows:

The following script is the main achievement of clicks which the text is displayed:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ShowContentScript : MonoBehaviour {
    void Update () {
        if (Input.GetKeyDown(KeyCode.A))
        {
            PrompPanel.isStartShowText = true;
            PromptMsg.Instance.Change("小松真帅",Color.red);
        }

        if (Input.GetKeyDown(KeyCode.B))
        {
            PrompPanel.isStartShowText = true;
            PromptMsg.Instance.Change("大荣真丑", Color.black);
        }
    }
}

下面这个脚本主要实现的是文字内容的显示与消失以及颜色的设置:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class PrompPanel : MonoBehaviour {

   
    private Text txt;
    private CanvasGroup cg;

    [SerializeField]
    [Range(0, 3)]
    private float showTime = 1f;

    private float timer = 0f;

    public static bool isStartShowText=false;

    void Start()
    {
        txt = transform.Find("Text").GetComponent<Text>();
        cg = transform.Find("Text").GetComponent<CanvasGroup>();

        cg.alpha = 0;
    }
    private void Update()
    {
        if (isStartShowText)
        {
            promptMessage(PromptMsg.Instance.Text, PromptMsg.Instance.Color);
            isStartShowText = false;
        }
    }
    /// <summary>
    /// 提示消息
    /// </summary>
    private void promptMessage(string text, Color color)
    {
        txt.text = text;
        txt.color = color;
        cg.alpha = 0;
        timer = 0;
        //做动画显示
        StartCoroutine(promptAnim());
    }

    /// <summary>
    /// 用来显示动画
    /// </summary>
    /// <returns></returns>
    IEnumerator promptAnim()
    {
        while (cg.alpha < 1f)
        {
            cg.alpha += Time.deltaTime * 2;
            yield return new WaitForEndOfFrame();
        }
        while (timer < showTime)
        {
            timer += Time.deltaTime;
            yield return new WaitForEndOfFrame();
        }
        while (cg.alpha > 0)
        {
            cg.alpha -= Time.deltaTime * 2;
            yield return new WaitForEndOfFrame();
        }
    }
}

　　上面两端代码就能够较为轻松的实现文本提示等内容的显示,这个东西我们可以设置我们的一个小工具类,当我们需要进行一些内容的显示的时候就可以用到上面这个方法了!!!!!!!!!!!!!!!!!!!!!!!!!!
