Thanks for the support. Our setup is as follows: A level is several times larger than the screen so that it is scrolled according to the movement of the player or directly with the joystick controller in the level editor. It consists of three layers. (1) background, i.e. the bottom z=0 with ratio 0.8, (2) obstacles, i.e. the center z=1 with ratio 1.0, (3) non-colliding objects which are “on top” z=2 with ratio 1.4. In the level editor, objects have to be places on layers (2) and (3).

I tried to construct a simple example of our setup since some code is worth a thousand words. Unfortunately, I seem to have introduced an error by this which I have not been able to track down yet. Here comes the main.qml which unfortunately crashes…

import VPlay 1.0
import QtQuick 1.1

GameWindow {
    activeScene: scene
    width: 960; height: 640
    focus: true
    Keys.forwardTo: controller

    EntityManager{
        id: entityManager
        entityContainer: levelContainer
        dynamicCreationEntityList: [Qt.resolvedUrl("Block.qml")]
    }

    TwoAxisController {
        id: controller
        inputActionsToKeyCode: {
            "up": Qt.Key_W,
                    "down": Qt.Key_S,
                    "left": Qt.Key_D,
                    "right": Qt.Key_A,
                    "fire": Qt.Key_Space
        }
    }

    MovementAnimation{
        target: levelContainer
        property: "pos"
        running: true
        property real scale: 200
        velocity: Qt.point(controller.xAxis*scale,controller.yAxis*scale)
    }

    Scene {
        id: scene
        width: 480
        height: 320

        LevelEditor {
            id: levelEditor
            toRemoveEntityTypes: ["obstacle"]
            toStoreEntityTypes: ["obstacle"]
        }

        // === LEVEL ===
        Item{
            id: levelContainer

            // === BACKGROUND ===
            ParallaxItem{
                id: background
                ratio: Qt.point(0.6,0.6)

                // some generated background...
                Grid{
                    rows: 10; columns: 10; spacing: 50
                    Repeater{
                        model: 100
                        Rectangle{
                            width: 100; height: 100
                            color: "grey"
                        }
                    }
                }
            }

            // === FOREGROUND ===
            ParallaxItem{
                id: levelgrid
                ratio: Qt.point(1,1)

                // some generated foreground...
                Grid{
                    rows: 10; columns: 10; spacing: 100
                    Repeater{
                        model: 100
                        Rectangle{
                            x: 100; y: 100
                            width: 50; height: 50
                            color: "red"
                        }
                    }
                }
            }

        }

//        BEButton{ }   // (*) we'll get to this later...
    }
}

Moreover, save the code of your last post to Box.qml.

The error message then is

EntityBase: entityDestroyed received, setting visible to false
destroy item in AbstractCCNodeManager: QObject(0x9b4b4c0) , nodeMgr: CCRectangleManager(0x9690118) 
the node to remove does not have a parent! that should never happen, because it means the root object wanted to be deleted! 
The program has unexpectedly finished.

What’s the matter here?

Cheers, Martin
