Hi I am making a quick program of a guy in my game and I need the right key to make him move right, same with left. But For some reason it wont work but my code has no errors. Can an animated sprite not be assigned functions like this? Do I need to make an alias or something? Here is my code

 

import QtQuick 2.7
import QtQuick.Window 2.2


Item {
width:Screen.width
height:Screen.height-10

Keys.onPressed: {

if (event.key===Qt.Key_up){
event.accepted = true;
sprite2.y=(sprite2.y) +25
}

}

Flickable{
width:Screen.width
height:Screen.height
contentHeight: Screen.height *4
contentWidth: Screen.width
interactive: true
boundsBehavior: Flickable.StopAtBounds

Image{
id: box
anchors.fill: parent
source: "artwork/rect.png"
sourceSize.width: Screen.width
sourceSize.height: Screen.height*4
}

AnimatedSprite {
    id: sprite2
    width: 100
    height: 200
    anchors.centerIn: parent
    source: "artwork/WalkingManSpriteSheet.png"
    frameCount: 8
    frameRate: 6
    frameWidth: 40
    frameHeight:60
    loops: 100
}

Image{
id:twitter
source: "artwork/twitter.png"
x:500
y:horizontalCenter
}
AnimatedSprite {
    id: sprite
    width: 300
    height: 425
    anchors.centerIn: hoizontalCenter
    source: "artwork/cannon.png"
    frameCount: 12
    frameRate: 8
    frameWidth: 128
    frameHeight:155
    loops: 100
}


}
}

Hi Todd,

the reason is most likely that the item you has no focus, and thus is not actively listening to key press events. Also I want to point you to our TwoAxisController that was designed exactly for your use-case. In the example usage of this component you also see the solution to your problem. The item that has focus must forward the key events to the key listener, in our case the TwoAxisController. The easiest way to keep track of the focus in your game is just using the activeScene property of the GameWindow. This will also set the focus property of the scene to true. Whenever you switch a scene, just update the activeScene property accordingly and you can be sure that your active scene is also focused.

Hope this was not too confusing 🙂

As a quick fix for you, you could also simply add

focus: true

to your Item, but it never hurts to get deeper insights right 😉

Cheers,
Alex

Hey so i tried setting the item’s focus to true and im not getting anything 🙁

this is the code

import QtQuick 2.7
import QtQuick.Window 2.2


Item {
width:Screen.width
height:Screen.height-10
focus: true

Keys.onPressed: {

if (event.key===Qt.Key_Right){
event.accepted = true;
sprite2.y=(sprite2.y) +25
}

}

Flickable{
width:Screen.width
height:Screen.height
contentHeight: Screen.height *4
contentWidth: Screen.width
interactive: true
boundsBehavior: Flickable.StopAtBounds

Image{
id: box
anchors.fill: parent
source: "artwork/rect.png"
sourceSize.width: Screen.width
sourceSize.height: Screen.height*4
}

AnimatedSprite {
    id: sprite2
    width: 100
    height: 200
    anchors.centerIn: parent
    source: "artwork/WalkingManSpriteSheet.png"
    frameCount: 8
    frameRate: 6
    frameWidth: 40
    frameHeight:60
    loops: 100

}

Image{
id:twitter
source: "artwork/twitter.png"
x:500
y:horizontalCenter
}
AnimatedSprite {
    id: sprite
    width: 300
    height: 425
    anchors.centerIn: hoizontalCenter
    source: "artwork/cannon.png"
    frameCount: 12
    frameRate: 8
    frameWidth: 128
    frameHeight:155
    loops: 100
}


}

I am kind of confused because for some reason when i switch the event to listen for twitter.png it will move the image when i press the keys. Just not for the sprite why is this?

Gunther,

Thanks for the help I found that after changing the anchors.Centerin property it worked
