基于Vuforia图像识别的自定义跟踪事件处理程序

创建一个脚本，你可以命名为
CustomTrackableEventHandler,
然后：
- 继承
DefaultTrackableEventHandler,
- 重载父类的函数
-
把
ImageTarget上的DefaultTrackableEventHandler换成CustomTrackableEventHandler
例子如下：
using
System.Collections; using
System.Collections.Generic;
using UnityEngine; public
class CustomTrackableEventHandler
: DefaultTrackableEventHandler
{ protected override
void OnTrackingFound( ) { var o =
GameObject.CreatePrimitive(PrimitiveType.Sphere);
o.transform.SetParent(mTrackableBehaviour.transform);
o.transform.localPosition =
Vector3.zero;
o.transform.localRotation =
Quaternion.identity;
o.transform.localScale =
Vector3.one; }
protected override void
OnTrackingLost()
{ if
(transform.childCount !=
0)
Destroy(transform.GetChild(0).gameObject);
} }
