飄血的文字

在Unity場景中新增一個Cube作為怪物，當我們點選滑鼠左鍵的時候產生傷害的文字，然後讓這些文字，慢慢向上移動，然後消失。

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

public class ShutHurt : MonoBehaviour {
   //這是一個Text的預製體，在做預製體的時候一定要記得文字居中，否則會有一個偏移量的
    public GameObject prefabs;

    public Vector3 offset;
 


    public Transform canvasTransform;

    public float moveSpeed;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        float horizontal = Input.GetAxis("Horizontal");
        float vertical = Input.GetAxis("Vertical");

        Vector3 moveDirect = transform.right
 
 * horizontal + transform.forward * vertical;

        transform.Translate(moveSpeed * moveDirect * Time.deltaTime);

        if (Input.GetMouseButtonDown(0))
        {
            GameObject temp = GameObject.Instantiate(prefabs);

            temp.transform.position = Camera.main.WorldToScreenPoint
 
(this.transform.position) + offset;
            Debug.Log("物體轉化後的螢幕座標" + Camera.main.WorldToScreenPoint(this.transform.position));
            Debug.Log("Text控制元件的螢幕座標" + temp.transform.position);
            temp.GetComponent<Text>().text = 50.ToString();
            temp.transform.SetParent(canvasTransform);

        }
    }
}

文字移動消失的程式碼

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class TextController : MonoBehaviour {

    public float speed;

    // Use this for initialization
    void Start () {
        Destroy(this.gameObject, 1f);
    }

    // Update is called once per frame
    void Update () {
        transform.Translate(Vector3.up * Time.deltaTime * speed);
    }
}


下面的圖是在新增Cube移動後的，飄血的文字不會因為物體移動遠了而變小，也不會因為物體移動近了而變大
