1. 苹果设备 因为搭建需要在iOS 11上完成，你需要一个拥有A9或者A10芯片的机器，所以AR Kit只能在一下机器上： -iPhone SE -iPhone 6s -iPhone 6s Plus -iPhone 7 -iPhone 7 Plus -iPad Pro - 9.7-inch iPad 2017
2. 安装Xcode 9 你需要在电脑上安装Xcode 9 https://developer.apple.com/xcode/
3. 升级到 iOS 11 你需要在支持iOS和AR Kit的设备上安装iOS 11 ，推荐使用手机操作，方便匹配。
登陆注册地址 https://beta.apple.com/sp/betaprogram/guide#ios 下载profile地址 https://beta.apple.com/sp/betaprogram/redemption#ios 然后回到手机设置 —> 通用 —> 软件更新，然后你就会看到iOS11更新选项了。点击更新，顺着流程完成更新下载。 4. 安装 Unity 官网下载：Unity - Download 注意安装 5.6版本以上的软件，我录制视频时使用的是 2017.1.0f3 的最新版本。 5. 开发 为表诚意，以下是Unity中修改的两个C#的文件，可以跟着视频自己敲，也可以参考这里的：
ZombieControl.cs using System.Collections;using System.Collections.Generic;using UnityEngine;public class ZombieControl : MonoBehaviour {
private Animation animation;
private bool moving = false;
// Use this for initialization
void Start () {
animation = GetComponent <Animation>();
}
// Update is called once per frame
void Update () {
if (moving) {
transform.Translate (Vector3.forward * Time.deltaTime * (transform.localScale.x * .05f));
}
}
public void Walk(){
if (!animation.isPlaying) {
animation.Play ();
moving = true;
} else {
animation.Stop ();
moving = false;
}
}
public void LookAt(){
transform.LookAt (Camera.main.transform.position);
transform.eulerAngles = new Vector3 (0, transform.eulerAngles.y, 0);
}
public void Bigger(){
transform.localScale += new Vector3(1,1,1);
}
public void Smaller(){
if (transform.localScale.x > 1) {
transform.localScale -= new Vector3(1,1,1);
}
}}
UnityARHitTestExample.cs using System;using System.Collections.Generic;using UnityEngine.EventSystems;namespace UnityEngine.XR.iOS{
public class UnityARHitTestExample : MonoBehaviour
{
public Transform m_HitTransform;
bool HitTestWithResultType (ARPoint point, ARHitTestResultType resultTypes)
{
List<ARHitTestResult> hitResults = UnityARSessionNativeInterface.GetARSessionNativeInterface ().HitTest (point, resultTypes);
if (hitResults.Count > 0) {
foreach (var hitResult in hitResults) {
Debug.Log ("Got hit!");
m_HitTransform.position = UnityARMatrixOps.GetPosition (hitResult.worldTransform);
m_HitTransform.rotation = UnityARMatrixOps.GetRotation (hitResult.worldTransform);
Debug.Log (string.Format ("x:{0:0.######} y:{1:0.######} z:{2:0.######}", m_HitTransform.position.x, m_HitTransform.position.y, m_HitTransform.position.z));
return true;
}
}
return false;
}
// Update is called once per frame
void Update () {
if (Input.touchCount > 0 && m_HitTransform != null)
{
var touch = Input.GetTouch(0);
if (touch.phase == TouchPhase.Began && !EventSystem.current.IsPointerOverGameObject(0))
{
transform.localPosition = Vector3.zero;
var screenPosition = Camera.main.ScreenToViewportPoint(touch.position);
ARPoint point = new ARPoint {
x = screenPosition.x,
y = screenPosition.y
};
// prioritize reults types
ARHitTestResultType[] resultTypes = {
ARHitTestResultType.ARHitTestResultTypeExistingPlaneUsingExtent,
// if you want to use infinite planes use this:
//ARHitTestResultType.ARHitTestResultTypeExistingPlane,
ARHitTestResultType.ARHitTestResultTypeHorizontalPlane,
ARHitTestResultType.ARHitTestResultTypeFeaturePoint
};
foreach (ARHitTestResultType resultType in resultTypes)
{
if (HitTestWithResultType (point, resultType))
{
return;
}
}
}
}
}
}}
