Hi Johanna,

since version 1.3 we support file reading with System::readFile(). However, in most cases you can achieve a better code style by defining a base QML file (like a LevelBase.qml) and then create multiple instances of it by subclassing this QML file.

After a failed VPlay update and a completely new installation VPlay 1.3 is running now 🙂 And i’ve found the readFile() function.

But we do not really understand why we need a base QML file. Do you mean for creating different levels?

If you just read levels, it is easier to define the levels in QML file and you do not need the loading from a file.

Have a look at the demo games like Squaby, where this concept is shown in detail.

Consider the following code:

LevelBase.qml:
Item {
 // the blocks variant could be any array or a map you define in the levels
 property variant blocks
}

Level01.qml:
LevelBase {
 // enter any level data here you need for your game
 blocks: [[10, 30, 50], [5, 10, 5]]
}

then, for loading the level:
Loader {
 source: "Level01.qml" // select any level here, possibly from a level selection scene
}

 

This is the suggested workflow with QML. File reading is only necessary if you also want to save some files, which is not the case I guess.

ok. this sounds logical and easier than reading from a file 🙂

i’ve tried it. but i don’t understand how to get all the single stones out of my property in the BaseLevel.qml. So i have following qml files:

BaseLevel.qml: contains a property with all data loaded from the Level.qml and a Loader (like shown in your post)

Level01.qml: like shown in your post

Stone.qml: implements mouse area, boxCollider, position, size of a stone. these data are saved in the property of the BaseLevel.qml. how can i access them?

 

i’ve tried to get this information out of the code of Squaby but i couldn’t find what i searched for.. may you help me?

Hi Johanna,

You can access the contents of the Loader with the item property. Please have look at the Loader documentation, or search for “Loader” in the demo games.

Cheers, Chris
