我正在尝试制作一个下拉菜单来统一更改我的播放器的颜色,但它不起作用。这是我的代码:
`using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class colorSelect : MonoBehaviour
{
public Dropdown ColorDropdown;
public static float speed;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
public void ChooseColor()
{
switch (ColorDropdown.value)
{
case 1:
GetComponent<Renderer>().material.color = Color.cyan;
break;
case 2:
GetComponent<Renderer>().material.color = Color.red;
break;
case 3:
GetComponent<Renderer>().material.color = Color.white;
break;
default: // speed if no item is selected. in this case, the player does not move
speed = 0.0f;
break;
}
}
}`
我尝试使用 switch 语句,然后将脚本附加到播放器,然后将播放器附加到下拉菜单,但它不起作用。
访问下拉列表值的通常方法是通过 OnValueChanged 事件。
这可能有用:
