Unity DropDown基本用法

创建一个Dropdown，再创建一个GameObject

GameObject挂上一个脚本testDropdown

?

1 2 3 4 5 6 7 8 9 10

using UnityEngine; using UnityEngine.UI;   public class testDropdown : MonoBehaviour {     public Dropdown dropdown;     public void EventListening()     {         Debug.Log(dropdown.value);     } }

 

将GameObject拖入Dropdown中，刚刚的代码作为监听脚本

 

此时控制台能根据选择项位置输出对应数字了：

 

 

补充：通过选项改变物体颜色：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

public class testDropdown : MonoBehaviour {     public Dropdown dropdown;     public GameObject gameObject;       public void EventListening()     {           switch(dropdown.value){             case 0:                 gameObject.GetComponent<MeshRenderer>().material.color = Color.white;                 break;             case 1:                 gameObject.GetComponent<MeshRenderer>().material.color = Color.red;                 break;             case 2:                 gameObject.GetComponent<MeshRenderer>().material.color = Color.green;                 break;             case 3:                 gameObject.GetComponent<MeshRenderer>().material.color = Color.blue;                 break;                          default:                 break;         }     } }<br><br>

 将需要改变颜色的GameObject拖进来即可。
