unity之KnapsackView

出售是先点击出售按钮，然后点击目标格子

简单布局

效果，当前为切换到背包2

测试背包类

using UnityEngine;public class Test : MonoBehaviour {    private void Start()    {        var knapsack = transform.GetComponentInChildren<KnapsackView>();        knapsack.GetChangedValue("Gold").text = "123";        knapsack.onLeftClick += x => {            Debug.Log("左击了格子 "+x.name);        };        knapsack.onArrange += () =>        {            Debug.Log("整理背包");        };        knapsack.onButtonClick += x =>        {            Debug.Log("点击了 " + x);        };        knapsack.onDoubleClick += x =>        {            Debug.Log("双击了 " + x.name);        };        knapsack.onRightClick += x =>        {            Debug.Log("右击了 " + x.name);        };        knapsack.onSell += x =>        {            Debug.Log("出售"+x.name);        };    }}
