本来按网上示例用RenderTexture截屏作为暂停菜单的背景，不过总是报错，有大神知道为什么吗？
关键代码：
…
bool TutorialSence::init()
{
if (!Layer::init())
{
return false;
}
...
auto visibleSize = Director::getInstance()->getVisibleSize();
auto origin = Director::getInstance()->getVisibleOrigin();
...
mRenderTexture = RenderTexture::create(visibleSize.width, visibleSize.height, Texture2D::PixelFormat::RGBA8888);
mRenderTexture->retain();
return true;
}
…
void TutorialSence::onKeyReleased(EventKeyboard::KeyCode keyCode, Event* event) {
switch (keyCode) {
case EventKeyboard::KeyCode::KEY_BACKSPACE:
onMenuItemSelectedWithTag(TUTORIAL_TAG_MENU);
break;
}
}
void TutorialSence::onMenuItemSelected(Ref* pSender) {
onMenuItemSelectedWithTag(((Node *)pSender)->getTag());
}
void TutorialSence::onMenuItemSelectedWithTag(int tag) {
switch (tag) {
case TUTORIAL_TAG_MENU:
auto visibleSize = Director::getInstance()->getVisibleSize();
auto origin = Director::getInstance()->getVisibleOrigin();
mRenderTexture->beginWithClear(0.0f, 0.0f, 0.0f, 0.0f);
getParent()->visit();
mRenderTexture->end();
auto _schedule = getParent()->getScheduler();
_schedule->schedule(schedule_selector(TutorialSence::onCatchImage), this, 0.0f,0,0.f, false);
break;
}
}
void TutorialSence::onCatchImage(float dt) {
// Director::getInstance()->pushScene(GameMenuSence::createScene(mRenderTexture));
}
