一、定义手柄按键API
1、InputDevices.GetDeviceAtXRNode,通过XRNode获取对应的设备;
2、XRNode是一个枚举类型,包含LeftEye、RightEye、CenterEye、Head、LeftHand、RightHand、GameController、TrackingReference、HardwareTracker;
3、TryGetFeatureValue,得到某个特性的值;
4、CommonUsages定义了用于从XR.InputDevice.TryGetFeatureValue获取输入特征的静态变量,用来指定想要获取的特性。

Vector2 vec2DAxis = Vector2.zero; bool isGrip = false ; bool isTrigger = false ; bool isMenu = false ; bool isPrimaryButton = false ; bool isSecondButton = false ; InputDevices.GetDeviceAtXRNode(XRNode.LeftHand).TryGetFeatureValue(CommonUsages.primary2DAxis, out vec2DAxis); InputDevices.GetDeviceAtXRNode(XRNode.RightHand).TryGetFeatureValue(CommonUsages.gripButton, out isGrip); InputDevices.GetDeviceAtXRNode(XRNode.RightHand).TryGetFeatureValue(CommonUsages.triggerButton, out isTrigger); InputDevices.GetDeviceAtXRNode(XRNode.RightHand).TryGetFeatureValue(CommonUsages.menuButton, out isMenu); InputDevices.GetDeviceAtXRNode(XRNode.RightHand).TryGetFeatureValue(CommonUsages.primaryButton, out isPrimaryButton); InputDevices.GetDeviceAtXRNode(XRNode.RightHand).TryGetFeatureValue(CommonUsages.secondaryButton, out isSecondButton); |
二、控制物体移动
编写脚本用手柄控制物体的前后左右移动,如果把脚本挂载到头显上,就变成控制自身的移动。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR;
public class ControlObject : MonoBehaviour
{
// Update is called once per frame
void Update()
{
Vector2 vec2DAxis = Vector2.zero;
InputDevices.GetDeviceAtXRNode(XRNode.LeftHand).TryGetFeatureValue(CommonUsages.primary2DAxis, out vec2DAxis);
transform.position = new Vector3(transform.position.x + vec2DAxis.x * Time.deltaTime,
transform.position.y, transform.position.z + vec2DAxis.y * Time.deltaTime);
}
}
