Hi,

I’m developing game like ant smasher. In my ‘SceneGame.qml’, I’ll create multiple entities from ‘Snail.qml’ using entityManager.createEntityFromUrl(Qt.resolvedUrl(“entities/Snail.qml”)).

Snail.qml will emit smashed() signal when it get clicked. But how to connect the signal from Snail to SceneGame?

=== SceneGame.qml ===

    function createEntities()
    {
        entityManager.createEntityFromUrl(Qt.resolvedUrl("entities/Snail.qml"));
        entityManager.createEntityFromUrl(Qt.resolvedUrl("entities/Snail.qml"));
    }

 

=== Snail.qml ===

    MouseArea
    {
        anchors.fill: colliderCiput
        onClicked:
        {
            pathMovement.stop()
            soundSplat.play()
            timerSplat.start()
            spriteSnail.opacity = 0
            imgSplat.opacity = 1
            smashed() // Signal
        }
    }

Hi Fahmy,

good question!

You can do the following:

Emit the signal in your GameWindow and emit it from there, like in the following example code:

// --- main.qml --- //
GameWindow {
 id: gameWindow

 signal snailSmashed
 
 Scene {
  id: gameScene
 }
}

// --- Snail.qml --- //
gameWindow.snailSmashed()

Cheers, Chris
