Mobil roll

[Viper666]

Hi,
I make a program with aim and it move when i roll phone. I try this Sensor (http://www.developer.nokia.com/Community/Wiki/Implementing_custom_orientation_changes_animation_ with_QML) but i want roll about 45°.
Can someone help me?

What exactly is the problem?

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" :D

[wysota]

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

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"
}
}
}

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

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:

import QtQuick 1.1

Rectangle {
id: root
width: 360
height: 360

Rectangle {
property bool hit: false
id: duck
width: 50
height: width
radius: width/2
color: "red"
y: 60
NumberAnimation on x {
duration: 3000
from: 0
to: root.width
loops: NumberAnimation.Infinite
running: !duck.hit
}
NumberAnimation on y {
duration: 500
to: root.height
running: duck.hit
}
}

Rectangle {
id: crosshair
width: 40
height: width
border.color: "black"
border.width: 1
color: "transparent"
}

MouseArea {
id: aim
anchors.fill: parent
hoverEnabled: true
onPositionChanged: {
crosshair.x = mouse.x-crosshair.width/2
crosshair.y = mouse.y-crosshair.height/2
}
onClicked: {
if(mouse.x >= duck.x && mouse.x <= duck.x+duck.width && mouse.y >= duck.y && mouse.y <= duck.y+duck.height) {
duck.hit = true
}
}

}
}

Here is another:

import QtQuick 1.1

Rectangle {
id: root
width: 360
height: 360

Rectangle {
property bool hit: false
id: duck
width: 50
height: width
radius: width/2
color: "red"
y: 60
NumberAnimation on x {
duration: 3000
from: 0
to: root.width
loops: NumberAnimation.Infinite
running: !duck.hit
}
NumberAnimation on y {
duration: 500
to: root.height
running: duck.hit
}
MouseArea {
anchors.fill: parent
onClicked: duck.hit = true

}
}

Rectangle {
id: crosshair
width: 40
height: width
border.color: "black"
border.width: 1
color: "transparent"
}

MouseArea {
id: aim
anchors.fill: parent
hoverEnabled: true
acceptedButtons: Qt.NoButton
onPositionChanged: {
crosshair.x = mouse.x-crosshair.width/2
crosshair.y = mouse.y-crosshair.height/2
}

}
}

i need this thanks
