[Viper666]

I have next problem i have two MouseArea, first is full background and second is only on one objeck but signals don't work now

[wysota]

Please define "don't work".

[Viper666]

onClicked:
{
console.log("this work")
}
I never see: "this work"

[wysota]

onClicked:
{
console.log("this work")
}
I never see: "this work"

This is not a valid QML file.

i don't understand my code simple

import ...
Item {
id: background
MouseArea {
id: mouse
onPositionChanged: { 
...
//something
...
}
}
Rectangle {
id: rect
MouseArea {
 onClicked: { console.log("work") }//this is only test that it's work but it's never emit i never see "work"
}
}
}

import ...
Item {
id: background
MouseArea {
id: mouse
onPositionChanged: { 
...
//something
...
}
}
Rectangle {
id: rect
MouseArea {
 onClicked: { console.log("work") }//this is only test that it's work but it's never emit i never see "work"
}
}
}

The code above will make the MouseArea have null size thus you will never hit it.

[Viper666]

i forgot anchors.fill: parent but it it there in each mousearea

[wysota]

In that case your first mouse area overlaps with the second one and overrides it. Thus the first mouse area will work and the second one will not.

ok i will make it else i have duck and i have own crosshair and shotbutton how can i do thath when you press shotbutton you will shot duck i can't use something like if(duck.x == aim.x && duck.y == aim.y) because i want full duck and not only one pixel?
Do you understand me sorry my English is horrible .

[wysota]

I don't understand what you mean. And it's not about the language, it's more about the content of your posts. You should really post a minimal complete example that demonstrates the problem.

Ok i make a game first time. I want simple game you must shot duck. And i don't know how make it. When you shot how can i detect that you shot duck
i can't use if(click.y == duck.y && click.x == duck.x) because you never click on this one pixel. So how can i do that? My first idea: Duck { MouseArea { id: mouse; onClicked: { console.log("shot"); }} but this is wrong because i have a aim(crosshair) image

[wysota]

I'd have to see some real code to be able to comment on it. I don't know how the crosshair is related to the action of "shooting". Are you "aiming" by hovering mouse and "shooting" by clicking it?

[Viper666]

Are you "aiming" by hovering mouse and "shooting" by clicking it?

Yes but now how detect that player shoot the duch?

Here is one possibility:

        y: 60
        NumberAnimation on x {
