[SailfishDevel] Qt.labs.particles not installed

[thuai]

I'm tring to port the 'samegame' which is a example of qml, you can find
the game source in the directory Qt installed.
The path of the game source on my pc is
/opt/Qt/Qt5.0.1/5.0.1/gcc_64/examples/declarative/samegame.
And i copy the source to my new Sailfish project directory.
And then i modify the code in main.cpp

' QScopedPointer<QDeclarativeView>
view(Sailfish::createView("samegame.qml"));'

run the project i modified.

when i click the 'New Game' button, get these error messages

error loading block component
file:///opt/sdk/share/SimpleGame/qml/SamegameCore/BoomBlock.qml:43
module "Qt.labs.particles" is not installed

Does this error mean Sailfish not suport particles element of QML?
Should i install some modules by SDK Control Center?
what should I do to solved this problem?

thks very much!
