Unity2D中实现JoyStick摇杆功能的具体代码
以下是一个简单的Unity2D中实现JoyStick摇杆功能的代码示例:
```csharp
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
public class JoyStick : MonoBehaviour, IDragHandler, IPointerUpHandler, IPointerDownHandler
{
private Image bgImg;
private Image joystickImg;
private Vector3 inputVector;
private void Start()
{
bgImg = GetComponent<Image>();
joystickImg = transform.GetChild(0).GetComponent<Image>();
}
public virtual void OnDrag(PointerEventData ped)
{
Vector2 pos;
if (RectTransformUtility.ScreenPointToLocalPointInRectangle(bgImg.rectTransform, ped.position, ped.pressEventCamera, out pos))
{
pos.x = (pos.x / bgImg.rectTransform.sizeDelta.x);
pos.y = (pos.y / bgImg.rectTransform.sizeDelta.y);
inputVector = new Vector3(pos.x * 2 + 1, 0, pos.y * 2 - 1);
inputVector = (inputVector.magnitude > 1.0f) ? inputVector.normalized : inputVector;
joystickImg.rectTransform.anchoredPosition =
new Vector3(inputVector.x * (bgImg.rectTransform.sizeDelta.x / 3),
inputVector.z * (bgImg.rectTransform.sizeDelta.y / 3));
}
}
public virtual void OnPointerDown(PointerEventData ped)
{
OnDrag(ped);
}
public virtual void OnPointerUp(PointerEventData ped)
{
inputVector = Vector3.zero;
joystickImg.rectTransform.anchoredPosition = Vector3.zero;
}
public float Horizontal()
{
if (inputVector.x != 0)
return inputVector.x;
else
return Input.GetAxis("Horizontal");
}
public float Vertical()
{
if (inputVector.z != 0)
return inputVector.z;
else
return Input.GetAxis("Vertical");
}
}
```
这个代码实现了一个简单的JoyStick摇杆功能,可以通过Horizontal()和Vertical()方法获取摇杆的输入值。

}
public float Horizontal()
{
if (inputVector.x != 0)
return inputVector.x;
else
return Input.GetAxis("Horizontal");
}
public float Vertical()
{
if (inputVector.z != 0)
return inputVector.z;
else
return Input.GetAxis("Vertical");
}
}
希望能对你有所帮助!
