How to add vibration in cocos2d-x C++

[i__d__k]

Continuing the discussion from How to add vibration to android game in cocos2d js?:

@raksa

in /frameworks/runtime-src/proj.android/AndroidManifest.xml
add: permission VIBRATE

in /frameworks/runtime-src/proj.android/src/org/cocos2dx/javascript/AppActivity.java
set:

import android.os.Vibrator;
public class AppActivity extends Cocos2dxActivity {
    private static AppActivity app = null;
    protected void onCreate(Bundle savedState) {
        super.onCreate(savedState);
        app = this;
    }
    public static void callVibration() {
        // Get instance of Vibrator from current Context
        Vibrator v = (Vibrator) app.getSystemService(Context.VIBRATOR_SERVICE);

        // Vibrate for 400 milliseconds
        v.vibrate(400);
    }
}

in js file
use:

if (cc.sys.os == cc.sys.OS_ANDROID) {
   jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "callVibration", "()V");
}

Thanks for the code, could you also provide the C++ implementation of vibration and if possible with the ability to pass the vibration time to the function?

[raksa]

in Java

    public static void callVibration(int time) {
        Vibrator v = (Vibrator) app.getSystemService(Context.VIBRATOR_SERVICE);
        v.vibrate(time);
    }

in Js

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "callVibration", "(I;)V", 400);

And about C++ is out of my experience, sorry

[i__d__k]

Thanks for the functions. I found the C++ implementation -
Include these -

#include "platform/android/jni/JniHelper.h"
#include <jni.h>

And this is the function -

JniMethodInfo methodInfo;
    if (JniHelper::getStaticMethodInfo(methodInfo, "org/cocos2dx/cpp/AppActivity", "callVibration", "(I;)V")) {
        methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID,400);
        methodInfo.env->DeleteLocalRef(methodInfo.classID);
    }

But when I try to compile it, I get the errors -

[javac] proj.android\src\org\cocos2dx\cpp\AppActivity.java :34: error: cannot find symbol
[javac]     protected void onCreate(Bundle savedState) {
[javac]                             ^
[javac]   symbol:   class Bundle
[javac]   location: class AppActivity
[javac] proj.android\src\org\cocos2dx\cpp\AppActivity.java:39: error: cannot find symbol
[javac]         Vibrator v = (Vibrator) app.getSystemService(Context.VIBRATOR_SERVICE);
[javac]                                                      ^
[javac]   symbol:   variable Context
[javac]   location: class AppActivity
[javac] 2 errors

I used the java code that you gave -

package org.cocos2dx.cpp;

import org.cocos2dx.lib.Cocos2dxActivity;
import android.os.Vibrator;

public class AppActivity extends Cocos2dxActivity {
    private static AppActivity app = null;
    protected void onCreate(Bundle savedState) {
        super.onCreate(savedState);
        app = this;
    }
    public static void callVibration(int time) {
        Vibrator v = (Vibrator) app.getSystemService(Context.VIBRATOR_SERVICE);
        v.vibrate(time);
    }
}

How can I fix this error?

[copang]

try “(I;)V” -> “(I)V”

[i__d__k]

@copang

try “(I;)V” -> “(I)V”

Thanks, that was also a problem I didn’t notice

I also fixed the java error by -

import android.os.Bundle;
import android.content.Context;

Hi, what about for iOS? Could you also provide the C++ implementation for iOS?

[ZippoLag]

It’d be great to get this working for WP too

[raydelto]

Vibration should be wrapped within the Cocos2d-x framework so we don’t have to hack a workaround for each platform.

Does ios app store (Apple) allowed custom vibration ??? i fear they might not … please share your thoughts on this.

[smitpatel88]

@shaqir29 No ios app store doesnt allow custom vibration. Also you have to provide vibrate on/off btn inside game to pass your game successfully.
