Question

I’m currently making a game called Snowflake to learn how to program QML with Javascript.

• I have my sourcecode here: https://gist.github.com/4510190.

The only files i got besides that is a default qmlproject file and a png file.

I have made this timer(Timer) and a rectangle(skullflake) which it should spawn for every interval it has finished.

Timer { //spawnrate
         interval: 2000; running: true; repeat: true
         onTriggered: Qt.createQmlObject(skullflake)
     }

But when I try to run it, it gives me the error:

file:///where/the/project/is/saved/Snowflake/Snowflake.qml:21: Error: Qt.createQmlObject(): Invalid arguments

I have tried with both these elements but I can’t seem to make it work

• Qt.createComponent(skullflake)

• Qt.createQmlObject(skullflake)

Answer 1

You were using wrong Qt.createQmlComponent().
It requires 3 parameters:

Qt::createQmlObject ( string qml, object parent, string filepath )

So it should look like something like this (parent should be id of element which should contain skullflake):

Timer { //spawnrate
         interval: 2000; running: true; repeat: true
         onTriggered: Qt.createQmlObject("YOUR skullflake QML CODE (NOT FILE PATH)", parent, "skullflake")
     }
