[游戏开发]Unity多相机OnMouseEnter等失效问题

用的unity版本为2021.1.11 URP，鼠标点击模型的OnMouseEnter失效

1、创建脚本，绑定在模型对应相机上

public class LiveCameraController : MonoBehaviour
{
    Camera cam;
    private IMouseEvent current;
    void Start()
    {
        cam = GetComponent<Camera>();
    }

    void Update()
    {
        Ray ray = cam.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {
            if (hit.transform.GetComponent<IMouseEvent>() != null)
            {
                if (current == null)
                {
                    current = hit.transform.GetComponent<IMouseEvent>();
                    current.OnMouseHover(true);
                }
                else
                {
                    if (hit.transform.GetComponent<IMouseEvent>() != current)
                    {
                        current.OnMouseHover(false);
                        current = hit.transform.GetComponent<IMouseEvent>();
                        current.OnMouseHover(true);
                    }
                }
            }
            else
            {
                if (current != null)
                {
                    current.OnMouseHover(false);
                    current = null;
                }
            }
        }
        else
        {
            if (current != null)
            {
                current.OnMouseHover(false);
                current = null;
            }
        }
    }
}

2、需要鼠标事件的物体脚本上继承接口IMouseEvent即可
