1、在proj.android這個目錄下
AndroidManifest.xml 文件，給app 增加震動權限
<uses-permission android : name = "android.permission.VIBRATE" />
2、 修改android 項目源文件src/org/cocos2dx/lib/Cocos2dxSound.java增加震動方法，調用android底層振動器
/*** @param time 震動時間 */
public void vibrate( long time) {
Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);
v.vibrate(time);
}
/** * @param pattern 震動時間數組 EG:{500,200,500,300}* @param repeat 重複次數 */
public void vibrateWithPattern( long [] pattern, int repeat) {
Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);
v.vibrate(pattern,repeat);
}
/*** 取消震動 */
public void cancelVibrate() {
Vibratorv = (Vibrator) mContext .getSystemService(Context. VIBRATOR_SERVICE);
v.cancel();
}
3. 至此，java 項目中的修改就OK啦，下面就是在Cocos2d-x中增加JNI方法讓C++去掉用Java的震動方法就OK啦!
3.1. 修改 libCocosDenshion 項目中cocos2d-x\CocosDenshion\android\jni文件夾下的SimpleAudioEngineJni.h和SimpleAudioEngineJni.cpp方法
在SimpleAudioEngineJni.h 中添加
#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 中添加
// 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 修改CocosDenshion/include/SimpleAudioEngine.h 增加如下方法.
void vibrate(long long time);
void vibrateWithPattern(long long pattern[], int repeat);
void cancelVibrate();
3.3 修改CocosDenshion/android/SimpleAudioEngine.cpp 增加調用JNI的如下方法。
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，代碼上的修改都OK 啦，在遊戲中需要使用震動的地方調用。
CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrate(time);
CocosDenshion::SimpleAudioEngine::sharedEngine()->vibrateWithPattern(pattern,repeat);
取消震動用這個
CocosDenshion :: SimpleAudioEngine :: sharedEngine () -> cancelVibrate ();
