cocos2d-xで自動スリープを禁止する

cocos2d-x v3.x で使えるようになった、cocos2d::Device::setKeepScreenOn(bool value) を呼ぶだけ

setKeepScreenOn method #7824 - cocos2d/cocos2d-x

実装は↑見ればわかるけど、よく使うiOSとAndroidは以下の様になってた

• iOS向け実装 (cocos2d/cocos/platform/ios/CCDevice-ios.mm)

void Device::setKeepScreenOn(bool value)
{
    [[UIApplication sharedApplication] setIdleTimerDisabled:(BOOL)value];
}

• Android向け実装 (cocos2d/cocos/platform/android/java/src/org/cocos2dx/lib/Cocos2dxActivity.java)

    public void setKeepScreenOn(boolean value) {
        final boolean newValue = value;
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                mGLSurfaceView.setKeepScreenOn(newValue);
            }
        });
    }
