Question

我在构建中测试了我的游戏，但是我收到了一个错误，我没有在编辑器中找到这里是构建图像：https://netane54544-gmail.tinytake.com/media/7608c0?filename=1525514080068_05-05-2018-12-52-30.png&sub_type=thumbnail_preview&type=attachment&width=1198&height=654

以下是编辑的图片：https://netane54544-gmail.tinytake.com/media/7608cc?filename=1525514464717_05-05-2018-12-58-59.png&sub_type=thumbnail_preview&type=attachment&width=1198&height=654

此处还有按钮代码：

private void Clicked()
{
    int index = 0;

    foreach (Gun item in gunSystem.secInventory)
    {
        Debug.Log(item.gunType);
        if (index == ButtonId)
        {
            if (gunSystem.guns_inInventory[playerScript.keyPress] == false)
            {
                gunSystem.setGunInvetory(playerScript.keyPress, item.Index.ToString());
                Worked = true;
            }
        }
        else
        {
            index++;
        }

    }
}

和setGunInvetory代码：

public void setGunInvetory(int n, string gunName)
{
    foreach (Gun item in secInventory)
    {
        Debug.Log(item.gunType);
        if (item.gunType == "Normal" && guns_inInventory[playerScript.keyPress] == false)
        {
            playerGuns[playerScript.keyPress] = Instantiate(Weapon_Normal, Camera.main.transform.position + (Camera.main.transform.forward * Normalview.offSetPosition.z) + (Camera.main.transform.right * Normalview.offSetPosition.x) + (Camera.main.transform.up * Normalview.offSetPosition.y), Quaternion.identity) as GameObject;
            playerGuns[playerScript.keyPress].name = gunName;
            playerGuns[playerScript.keyPress].transform.parent = gameObject.transform;
            playerGuns[playerScript.keyPress].transform.eulerAngles = gameObject.transform.eulerAngles + Normalview.startOffsetRotation;
            setGunActive(playerScript.keyPress);

            //Store gundata in inventory
            item.Named = false;
            Inventory[playerScript.keyPress] = item;
            guns_inInventory[playerScript.keyPress] = true;
        }
        else if (item.gunType == "Stride" && guns_inInventory[playerScript.keyPress] == false)
        {
            playerGuns[playerScript.keyPress] = Instantiate(Weapon_Stride, Camera.main.transform.position + (Camera.main.transform.forward * Strideview.offSetPosition.z) + (Camera.main.transform.right * Strideview.offSetPosition.x) + (Camera.main.transform.up * Strideview.offSetPosition.y), Quaternion.identity) as GameObject;
            playerGuns[playerScript.keyPress].name = gunName;
            playerGuns[playerScript.keyPress].transform.parent = gameObject.transform;
            playerGuns[playerScript.keyPress].transform.eulerAngles = gameObject.transform.eulerAngles + Strideview.startOffsetRotation;
            setGunActive(playerScript.keyPress);
            playerGuns[playerScript.keyPress].GetComponent<Renderer>().material = Stride_Material;

            //Store gundata in inventory
            item.Named = false;
            Inventory[playerScript.keyPress] = item;
            guns_inInventory[playerScript.keyPress] = true;
        }
    }
}

Answer 1

OP在评论中提到问题在于这一行

playerGuns[playerScript.keyPress] = Instantiate(Weapon_Normal, Camera.main.transform.position + (Camera.main.transform.forward * Normalview.offSetPosition.z) + (Camera.main.transform.right * Normalview.offSetPosition.x) + (Camera.main.transform.up * Normalview.offSetPosition.y), Quaternion.identity) as GameObject;

将第一个罪魁祸首带到playerGuns。 NullReferenceException发生了playerGuns，因为new Dictionary<TKey, TValue>()字典仅被声明并且未使用Dictionary<TKey,TValue> playerGuns = new Dictionary<TKey, TValue>();初始化，因此保持为null而不是初始化的空字典。

这里的解决方案是在使用之前创建字典的新实例：

<body>
<div id="app">
    <ul>
        <li v-for="text,i in todoList" v-on:click="method_1(i)" >{{text}}</li>
    </ul>
    <ul>
        <li v-for="text,i in todoList" v-on:click="method_2" >{{text}}</li>
    </ul>
    <ul>
    </ul>
</div>
<script src="https://cdn.bootcss.com/vue/2.5.16/vue.min.js"></script>
<script>
    new Vue({
        el:"#app",
        data:{
            todoList:["aaaaa",'bbbbbb','ccccc']
        },
        methods:{
            method_1:function(i){
                console.log(i) // i is index of v-for
            },
            method_2:function(e){
                console.log(e)
            },
        }
    })

</script>
</body>

构建中的Unity错误在编辑器中没有发生
