Hello everyone, I’m new to game development (just recently learned C++) and this looked like a good 2D game engine to start learning in. So, I downloaded the newest version of the engine, and started at the tutorial at (http://felgo.com/doc/vplay-entity-concept/). I got through the first part (Displaying the box on the screen) without any problems, but the next part (Adding the physics) gives an error on the z property; ‘Invalid property name “z”. (M16).’ I looked up the error and a found post on StackExchange saying to put “// @disable-check M16” before the z property, so I did, it got rid of the error, but when I run the game, all it shows is the Felgo splash screen and then a blank white screen; no box, and no falling box. Is there a working fix to this? Or should I switch over to a different engine? I don’t want to struggle against the engine while I’m trying to learn.

Thanks in advance.

Hi,

the reason for this is that the gravity already starts to affect the box while the splash screen is displayed. So until it is finished, the box has already fallen down. As soon as you add the ground wall, you will see the box stays on it after the splash finished. We’ll update this tutorial to only start falling after the splash is finished (and will update the z property), thanks for bringing this up!

If you have any other questions about the tutorials or the sample games, just let us know here in the forums.

Cheers, Chris

That makes sense, once I added the floor the box was visible again. Thank you for your quick helpful response.

It run ok in debug mode but in normal mode execution it shows the following error:

 

8276:error:02001015:system library:fopen:Is a directory:.\crypto\bio\bss_file.c:126:fopen(‘e:\repo\openssl_install.9.8zd\vc9\x86/ssl/openssl.cnf’,’rb’)

8276:error:2006D002:BIO routines:BIO_new_file:system lib:.\crypto\bio\bss_file.c:131:

8276:error:0E078002:configuration file routines:DEF_LOAD:system lib:.\crypto\conf\conf_def.c:199:

 

Do you know how I can fix it?

 

Thank you

Hi,

which compiler are you using? Do you experience this problem also when creating a Qt-Quick application (without using Felgo)?

Cheers,

a very simple appPlayground when defines as new item cannot find it no matter what. will i be able to get rid off “Invalid Property name ‘betechItem (M16)’?

Does Felgo team come from Sencha Touch? They had the same kind of nasty errors. Please let me know what the hell made me stuck on a very simple step.

 

If it was just to confirm that i am successfully stuck at the right place learning felgo then you guys are too smart for me  🙂

 

Please let me know what the hell is going on.

 

betechItem.qml

import Felgo 3.0
import QtQuick 2.0

Item {

    AppText{
     text: "Betech Item here"
    }

}

 

betechApp.qml

import Felgo 3.0
import QtQuick 2.0


 App {
    id: betechApp
    betechItem{} // here it hangs me up on M16 invalid propert name betechItem
  }

Hi Berka,

first of all, grab a coffee, calm down and let’s tackle your issue in a meaningful way.

Can you share your code that causes this issue? (There is a “code” button in the reply box to do this)

Cheers,
Alex

Brother, Thank you for coffee thing and the flying rocket like reply.

Please let me know if i can export everything and attach with my question. Or may be you need to check again. i edited the question so that you can see the code. I am very new to learning Felgo. Please think of me a dummy and take it easy

Alex,

I am following tutorial on udemy. In the video instructor was not stuck on the step i got stuck on. Please let me have url if there is any for a step by step guide. Thank you.

 

True Regards,

[Berka Frenfert]

I have time so i request on this forum to look at my code and at least give me a hint if it is my code the reason for M16 error or is it something else causing the problem. I promise to spend 2 more days just to figure out what went wrong.

Please let me know how to edit/delete my question/reply ?  The new question or reply does show the edit option but there is no delete option. Actually, i want to delete my old question. How to do that?

Hi Berka,

the QML language defines types to start with an uppercase letter, and properties with a lowercase letter. So if you rename your file to BetechItem.qml and use it as BetechItem then it will work fine.

The error you see is that, as per definition of QML, the compiler treats betechItem as a property of the App component, but the App component does not have a property with such a name –> error.

I hope that is clear and it could resolve your question.

Cheers,
Alex

Hi Alex,

it worked now with BetechItem. I continued the tutorial. Thank you.
