拓展BaseInputModule

使用鼠标模拟VR设备操作

using UnityEngine.EventSystems;
using UnityEngine;
namespace Framework.VR
{
    /// <summary>
    ///按下鼠标左键，手柄Z轴方向获取UI对象，通知对象被点击
    /// </summary>
    public class VRInputModule : BaseInputModule
    {
        [SerializeField] Camera eventCamra;//画布使用的事件相机
        [SerializeField] Transform hand;//手柄变换

        public override void Process()
        {
            if (input.GetMouseButtonDown(0))//模拟VR设备按下
            {
                eventCamra.transform.position = hand.position;

                eventCamra.transform.rotation = hand.rotation;

                PointerEventData eventData = new PointerEventData(eventSystem);

                eventData.position = new Vector2(eventCamra.pixelWidth, eventCamra.pixelHeight) * 0.5f;

                eventSystem.RaycastAll(eventData, m_RaycastResultCache);//检测

                eventData.pointerCurrentRaycast = FindFirstRaycast(m_RaycastResultCache);

                m_RaycastResultCache.Clear();

                ExecuteEvents.ExecuteHierarchy(eventData.pointerCurrentRaycast.gameObject,
                    eventData, ExecuteEvents.pointerDownHandler);//通知点击
            }
        }
    }
}

测试脚本：点击图片，图片改变颜色

using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;
/// <summary>
///图片改变颜色
/// </summary>
[RequireComponent(typeof(Image))]
public class TestClick : MonoBehaviour, IPointerDownHandler
{
    Image image;
    Color color;

    private void Awake()
    {
        image = GetComponent<Image>();
        color = image.color;
    }

    public void OnPointerDown(PointerEventData eventData)
    {
        color.r = Random.Range(0f, 1f);
        color.g = Random.Range(0f, 1f);
        color.b = Random.Range(0f, 1f);
        image.color = color;
    }
}
