cocos2d-x3.2中加入Android手机震动

       本人宣布从此博文发出后，我的cocos2dx的引擎从cocos2dx3.1.1跳到cocos2dx3.2，哈哈，事实上变化不大的，不碍事~~~

      以下来说说在cocos中加入Android手机震动的功能。亲身体验，网上的教程都是渣渣啊。坑比的非常，还要看了原帖http://www.cocos2d-x.org/boards/6/topics/8179，全英文的。蛋疼恼火了许久，才解决~~

      以下进入正题。相信看完本文，什么问题都ok了！！！。

1、在proj.android这个文件夹下

AndroidManifest.xml文件。给app添加震动权限

<uses-permission android:name="android.permission.VIBRATE" />

2、改动android项目源文件src/org/cocos2dx/lib/Cocos2dxSound.java添加震动方法，调用android底层振动器

/*** @param time震动时间*/

    public void vibrate(long time) {

        Vibratorv = (Vibrator) mContext.getSystemService(Context.VIBRATOR_SERVICE);

        v.vibrate(time);

    }

    /** * @param pattern   震动时间数组 EG:{500,200,500,300}*@param repeat反复次数*/

    public void vibrateWithPattern(long[] pattern,int repeat) {

        Vibratorv = (Vibrator) mContext.getSystemService(Context.VIBRATOR_SERVICE);

        v.vibrate(pattern,repeat);

    }

    /*** 取消震动 */

    public void cancelVibrate() {

        Vibratorv = (Vibrator) mContext.getSystemService(Context.VIBRATOR_SERVICE);

        v.cancel();

    }

3.至此，java项目中的改动就OK啦，以下就是在Cocos2d-x中添加JNI方法让C++去掉用Java的震动方法就OK啦!

3.1.改动 libCocosDenshion项目中cocos2d-xCocosDenshionandroidjni目录下的SimpleAudioEngineJni.h和SimpleAudioEngineJni.cpp方法

在SimpleAudioEngineJni.h中加入

#ifndef __SIMPLE_AUDIO_ENGINE_JNI__

#define __SIMPLE_AUDIO_ENGINE_JNI__

#include

extern "C"

{

         ......

         // add thesementhod

         extern void vibrateJNI(long long time);

         extern void vibrateWithPatternJNI(long long pattern[], intrepeat);

         extern void cancelVibrateJNI();

}

#endif // __SIMPLE_AUDIO_ENGINE_JNI__

在SimpleAudioEngineJni.cpp中加入

// add these jni menthod

void vibrateJNI(long long time)

{

         JniMethodInfomethodInfo;

         if (! getStaticMethodInfo(methodInfo, "vibrate", "(J)V"))

         {

                   return;

         }

         methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, time);

         methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

void vibrateWithPatternJNI(long long pattern[], int repeat)

{

         JniMethodInfomethodInfo;

         if (! getStaticMethodInfo(methodInfo, "vibrateWithPattern", "([JI)V"))

         {

                   return;

         }

         int elements = sizeof(pattern);

         jlongArrayjLongArray = methodInfo.env->NewLongArray(elements);

         methodInfo.env->SetLongArrayRegion(jLongArray, 0, elements, (jlong*) pattern);

         methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, jLongArray, repeat);

         methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

void cancelVibrateJNI()

{

         JniMethodInfomethodInfo;

         if (! getStaticMethodInfo(methodInfo, "cancelVibrate", "()V"))

         {

                   return;

         }

         methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID);

         methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

3.2改动CocosDenshion/include/SimpleAudioEngine.h添加例如以下方法.

void vibrate(long long time);

void vibrateWithPattern(long long pattern[], int repeat);

void cancelVibrate();

3.3改动CocosDenshion/android/SimpleAudioEngine.cpp添加调用JNI的例如以下方法。

void SimpleAudioEngine::vibrate(long long time)

{

         vibrateJNI(time);

}

void SimpleAudioEngine::vibrateWithPattern(long long pattern[], int repeat)

{

         vibrateWithPatternJNI(pattern, repeat);

}

void SimpleAudioEngine::cancelVibrate()

{

         cancelVibrateJNI();

}

4.至此。代码上的改动都OK啦，在游戏中须要使用震动的地方调用。

CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrate(time);

CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrateWithPattern(pattern,repeat);

取消震动用这个

CocosDenshion::SimpleAudioEngine::sharedEngine()->cancelVibrate();

最后在中加上这个

Coco2dxHelper.java中

public static void vibrate(long time)
{
sCocos2dSound.vibrate(time);
}

public static void vibrateWithPattern(long[] pattern, int repeat) {
sCocos2dSound.vibrateWithPattern(pattern, repeat);
}
/**
* 取消震动

到这里就圆满完毕了，网上的教程没有最后一步。所以说最后一步尤其关键。
