Hello,

I’m using LevelEditor and I would like to know if it is possible to save all the data that contains an entity ?
As I could see, there are always these data saved :

{"entityData":{"fichierTest_5":{"entityId":"fichierTest_5","entityType":"fichierTest","variationType":"","x":90,"y":72,"rotation":0}}

But my entity have other properties that I want to save. For example :

EntityEntry{
    id: domainEntry
    entityType: "domainEntry"
    variationType: "domainEntry"

    property string name
    property string type
    property int memory


}

What should I do to solve this ?

Hi Vladimir,

excellent question! 🙂

Are you also using the ItemEditor to change the properties at runtime for balancing during game creation? If you use it, the entities you use with ItemEditor are automatically stored with the LevelEditor.

If you do not want to use ItemEditor (although I’d strongly recommend it), you can use EntityBase::toStoreProperties to define which properties you want to save in a call of LevelEditor::saveCurrentLevel().

Cheers, Chris

Thank you Chris for your solutions !
I tried with “toStoreProperties” but my application crashed :

qml: EntityManager: storeEntitesAsJson: storing entity Entity_QMLTYPE_52(0x2d4b320, "entity_switchEntity_5") of type entity and id entity_switchEntity_5
qml: EntityManager: storing property from toStoreProperties array of entity entry with value SwitchEntry_QMLTYPE_187(0x313db10, "switchEntry_switchEntry_4")
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

I have this structure :
– Entity is a component specialized into SwitchEntity.
– an Entity has an EntityEntry ( specialized into SwitchEntry )

So we have
“Abstract Components”

//Entity.qml
EntityBaseDraggable{
    id: entity
    entityType: "entity"
    toStoreProperties: ["entry"]

    property EntityEntry entry
}

//EntityEntry.qml
Entry{
    id: entityEntry
    entityType: "entityEntry"
    variationType: "entityEntry"

    property bool saved: false
    property bool isTemplate: false
    property bool isModel: false
    property bool hasRessources: false

    property EntryProperties properties
}

 

 

“Concret Components”

//SwitchEntity.qml
Entity{
    id: switchEntity
    entityType: "entity"
    variationType: "switchEntity"
    entry: entry

    Image{
        id: image
        anchors.fill: parent
        source: "../../assets/switch.svg"
    }


    SwitchEntry{
        id: entry
    }
}

//SwitchEntry.qml
EntityEntry{
    id: switchEntry
    entityType: "switchEntry"
    variationType: "switchEntry"
    properties: properties

    property string type
    property int ports
    property bool isHub
    property bool stpEnabled
    property int portMirroring

    SwitchEntryProperties{id: properties}


}

 

I don’t know why it is crashing when I’m saving the level ( It happens when I want to store a component property )
I tried your first solution by putting an ItemEditor in my Scene but the data still are the same.

The toStoreProperties must be basic types like int, string, arrays or variants and cannot be a custom QML type. Please try to change the structure to only save the stored properties within your EntityEntry.
