本章节实现了冷却时间，伤害数字的弹出文本特效
PopUpTextFx.cs
1. 类成员变量
myText: 存储TextMeshPro组件的引用，控制文本的显示内容和颜色。speed: 控制文本上升的速度。disappearanceSpeed: 在文本透明度消失后，控制文本的上升速度衰减。colorDisappearanceSpeed: 控制文本透明度的衰减速率。lifeTime: 文本显示的总时长，超出这个时间后文本会开始消失。textTimer: 用于倒计时，跟踪文本的生命周期。
2. Update() 方法
-
文本上升：每帧通过
Vector2.MoveTowards使文本沿Y轴缓慢上升。speed控制上升速度，Time.deltaTime确保上升速度与帧率无关。 -
生命周期管理：
textTimer递减，当生命周期结束后（textTimer < 0），文本开始逐渐消失。 -
透明度衰减：文本的透明度（
alpha）逐渐减少，使用colorDisappearanceSpeed控制衰减速度。 -
减慢上升速度：当透明度低于50时，减慢文本的上升速度，使其在消失时更加平滑。

EntityFX.cs
添加部分!!!
功能分解
-
生成随机位置偏移量：
- 通过
Random.Range生成随机的偏移值，使弹出文本在一定范围内有随机性，增加视觉多样性。 randomx：控制X轴上的随机偏移，范围在[-0.5, 0.5]。randomy：控制Y轴上的随机偏移，范围在[1.5, 3]。
- 通过
-
实例化弹出文本：
- 使用
Instantiate方法在当前物体位置加上偏移量的地方创建一个新的弹出文本对象。 Quaternion.identity表示弹出文本没有旋转（即默认角度）。
- 使用
-
设置文本内容：
- 通过
newText.GetComponent<TextMeshPro>().text将输入的_text参数赋值给弹出文本的内容。
- 通过
[Header("弹出文本")]//Pop Up Text[SerializeField] private GameObject popUpTextPrefab;public void CreatePopUpText(string _text)//生成弹出文本{float randomx = Random.Range(-0.5f, 0.5f);float randomy = Random.Range(1.5f, 3);Vector3 positionOffset = new Vector3(randomx, randomy, 0);GameObject newText = Instantiate(popUpTextPrefab, transform.position + positionOffset, Quaternion.identity);newText.GetComponent<TextMeshPro>().text = _text;}完整代码！！！
