可以通过以下步骤实现:
1. 在Unity中创建一个UI按钮,将其命名为“Zoom In”或“Zoom Out”,并将其放置在场景中。
2. 创建一个脚本并将其附加到UI按钮上。在脚本中,添加以下代码:
```
using UnityEngine;
using UnityEngine.EventSystems;
public class ZoomButton : MonoBehaviour, IPointerClickHandler
{
public float zoomSpeed;
public void OnPointerClick(PointerEventData eventData)
{
if (eventData.button == PointerEventData.InputButton.Left)
{
// Zoom In
Camera.main.transform.localScale *= 1 + zoomSpeed;
}
else if (eventData.button == PointerEventData.InputButton.Right)
{
// Zoom Out
Camera.main.transform.localScale *= 1 - zoomSpeed;
}
}
}
```
3. 在脚本中,添加一个公共变量来控制缩放速度。您可以根据需要调整此变量的值。
4. 将Camera.main.transform.localScale乘以1 + zoomSpeed或1 - zoomSpeed,以进行缩放。这将根据鼠标滚轮向上或向下滚动而进行缩放。
5. 保存并运行您的场景,现在您应该能够通过单击UI按钮并滚动鼠标滚轮来控制物体的缩放了。
