[lexan]

I have started with my game a sort of typing maniac like game. I am would like to ask some help with this.
In this game after clicking the button, there would be falling objects with in mine, a falling fire in the screen
but after doing some QMLing, nothing has appeared on the screen as I have intended.. Please help me out

this is the codes for the falling object

@Item {
id: block

Image {
    id: img
    anchors.fill: parent
    source: "K:/mukha/fire.png"
}
NumberAnimation on y {
        to: screen.height / 2
        running: created
        onRunningChanged: {
            if (running)
                duration = (screen.height - img.y) * 10;
            else
                state = "OffScreen"
        }
    }

    states: State {
        name: "OffScreen"
        StateChangeScript {
            script: { img.created = false; img.destroy() }
        }
    }

}
@

after that this is javascript code

@var first=1;
var last=0;
var total=20;
var timeSinceLast=0;
var speed=5;
var posInWindow

function startNewGame(){
if(timeSinceLast>20){
if(last<total){
if(Math.random()<.1){

            last++;
            createBlock();
            timeSinceLast=0;
            if(speed<100)speed+=.5

        }
    }
}
    timeSinceLast++;

}

function createBlock(){
if (component == null)
component = Qt.createComponent("Block.qml");

if(component.status==Component.Ready){
    var dynamicObject = component.createObject(background);
    if(dynamicObject == null){
        console.log("error");
        console.log(component.errorString());
        return false;
    }
   // dynamicObject.type=Math.floor(Math.random()*3)
    dynamicObject.x= posInWindow.x;
    dynamicObject.y= posInWindow.y;

}else{
    console.log("error");
    console.log(component.errorString());
    return false;
}

return true;
}
@

and the code for the button in my main.qml

@
Button {
anchors { left: parent.left; verticalCenter: parent.verticalCenter }
text: "New Game"
onClicked: SameGame.startNewGame()
}@

there are no errors shown in the application output panel so I'm kinda confuse.. please help

Have you tried clicking on the Button more than 20 times? If I read the code correctly, startNewGame() is called on each click, but it only creates a block if timeSinceLast > 20.

Yes I did. after 20 + times there shows an error
