一、下面展示一些 游戏体缩放源码。

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

public class TweenScale : MonoBehaviour { 
   
    private float tween;
    private bool sign;
    void Start()
    { 
        tween = 1;
        sign = true;
    }

    void Update()
    { 
        //print(tween);
        if (sign == false)
        { 
            if (tween > 0.8f)
            { 
            this.gameObject.GetComponent<Transform>().localScale = new Vector3(tween, tween, 1);
                tween = tween - 0.008f;
            }
            else sign = true;
        }
        if (sign)
        { 
            if (tween < 1.2f)
            { 
                this.gameObject.GetComponent<Transform>().localScale = new Vector3(tween, tween, 1);

        }

    }

二、下面展示一些 Image或text透明闪烁的动画源码。

using UnityEngine.UI;

public class TweenAlpha : MonoBehaviour { 
    private Image tweenAlpha_Image;
    private Text tweenAlpha_Text;
    private float tween ;
    private bool sign;

    /// 闪烁速度
    /// </summary>
    public float speed = 7;
    /// <summary>
    /// 透明度最低值
    /// </summary>
    public float alphaMin = 50;
    //变化的颜色 RGBA值
    public float R = 255;
    public float G =255;
    public float B = 255;
    private bool imageSign = true;
    void Start()
    { 
        tweenAlpha_Image = this.gameObject.GetComponent<Image>();
        if (tweenAlpha_Image == null) { 
            tweenAlpha_Text = this.gameObject.GetComponent<Text>();
            imageSign = false;
        }
        tween = 255;
        sign = true;
    }
    
    void Update()
    { 
        if (imageSign)
        { 
            if (sign)
            { 
                if (tween > alphaMin)
                { 
                    tweenAlpha_Image.color = new Color(R / 255f, G / 255f, B / 255f, tween / 255f);
                    tween = tween - speed;
                }
                else sign = false;
            }
            if (sign == false)
            { 
                if (tween < 255)
                { 
                    tweenAlpha_Image.color = new Color(R / 255f, G / 255f, B / 255f, tween / 255f);
                    tween = tween + speed;
                }
                else sign = true;
            }
        }
        else
        { 
            if (sign)
            { 
                if (tween > alphaMin)
                { 
                    tweenAlpha_Text.color = new Color(R / 255f, G / 255f, B / 255f, tween / 255f);
                    tween = tween - speed;
                }
                else sign = false;
            }
            if (sign == false)
            { 
                if (tween < 255)
                { 
                    tweenAlpha_Text.color = new Color(R / 255f, G / 255f, B / 255f, tween / 255f);
                    tween = tween + speed;
                }
                else sign = true;
            }
        }

    }
}

三、下面展示一些 带有SpriteRenderer组件的游戏体透明闪烁的动画源码。

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

public class TweenAlpha : MonoBehaviour { 
    private SpriteRenderer tweenAlpha;
    private float tween ;
    private bool sign;
    void Start()
    { 
        tweenAlpha = this.gameObject.GetComponent<SpriteRenderer>();
        tween = 255;
        sign = true;
    }
    
    void Update()
    { 
        if (sign)
        { 
            if (tween > 50)
            { 
                tweenAlpha.color = new Color(1, 1, 1, tween / 255f);
                tween = tween - 6f;
            }
            else sign = false;
        }
        if (sign == false)
        { 
            if (tween < 255)
            { 
                tweenAlpha.color = new Color(1, 1, 1, tween / 255f);
                tween = tween + 6f;
            }
            else sign = true;
        }

    }
