我正在尝试通过C#代码设置Slider值。
我有一个Main.scene
,其中包含一个名为Slider的滑块。
主摄像头附有游戏管理器脚本。
滑块不是Interactable(因此我可以显示该值,但用户无法更改它)。
我定义了一个变量:
[SerializeField] private Slider sliderObj;
并将我的滑块放在此字段中的检查器中
我有一个浮动s
变量,我想在滑块中反映出来:
s = player1Time / (player1Time + player2Time) * 100.0f;
但是当我写道:
sliderObj.value = s;
我看到了这个错误:
'滑块'不包含'值'的定义没有延伸方法'价值'接受第一个类型为' Slider'可以找到(你错过了使用指令或程序集引用吗?)[Assembly-CSharp]
任何想法?
以下是整个脚本:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class GameManager : MonoBehaviour
{
public static GameManager instance = null; //this is to create a singleton => only one instance of this script running in memory
//so we only have one Game Manager running on memory

首先,感谢您的帮助 特别是bpgeck与我聊天,并帮助了我很多。 程序员也是对的。 我遇到的主要问题是调用附加到我的滑块Slider的脚本的致命错误(我仍然是一个菜鸟,但学习) 我删除了那个脚本并创建了一个名为Slider Percentage的新脚本,在其中我使用update函数来更改滑块的值:
GameObject temp;
// Use this for initialization
void Start () {
temp = GameObject.Find("Slider");
}
// Update is called once per frame
void Update () {
temp.GetComponent<Slider>().value = GameManager.instance.GetPercentage;
}
百分比值仍在GameManager中计算,但使用此脚本显示 现在一切都有效!!再次感谢您的帮助: - )
