ENIGMA Development Environment

Hello, I think you noticed the storm that the release of the new Unreal Engine v.4 brought.
$19 per month, including mobile and access to source code
Takes 5% of your games' gross income

That 5% royalty may not be so cheap, but sure beats Unity's $1500 for Pro + $1500 for iOS Pro + $1500 for Android Pro.
And it's cheaper than Game Maker Studio Professional + plugins.

First the CEO of Unity3D releases an interview stating that UE4 has had no impact on Unity.

Yet now they open a forum topic titled Official: How Can We Serve You Better?

If you use Qt, you are more or less invited to use their version of the standard library.
That is, qString instead of string, for example. If you read a qTextField, you get a qString instead of a string.
It's just that it gives you some more functionalities and checks.

You can use the Qt IDE to design the GUI, and it's quite good, so there's no need to fire up Visual Studio at all.
Unlike Java, which adopts the same GUI to rule them all, Qt provides a native look for each platform.
Truth is, sometimes it's not perfectly native, but you won't need any native calls and it will spare you any #ifdef.

License wise, it's the same as using the std library, you can release as closed source unless you mod the Qt library itself.
And even then you would just need to release the changes you made to the library and not your whole program.

LGPL was originally made for libraries.
You can use the library in your program without releasing the code of your program.
If you want to modify the code of the library itself, then you have to release the mod to the library under the same license (LGPL).

What's all the fuss about the dynamic / static linking?
Some people consider static linking as merging the code of your program with the code of the library.
And so they say that you should release the code of your program under the same license of the library.
It's not exactly like that, but use dynamic linking and everything will be fine.
In case you do want to investigate further, here you go

That said, Qt is a HUGE framework, far bigger than Java standard library.
Fortunately, it's truly modular and it's written with a more consistent style.
Make sure you understand the style they are "suggesting" you to use, or you'll be swimming against the tide.

What kind of solution did you adopt to solve this?
I've never heard of such "liczykon" script.

Thanks for bringing those 2 very nice examples to our attention.

That wxWidgets exception to GPL is a very nice trick. But wxWidgets is a library.

2. The exception is that you may use, copy, link, modify and distribute
under your own terms, binary object code versions of works based on the
Library.

And you can't adapt the license to fit Enigma either

              wxWindows Library Licence, Version 3.1
              ======================================

Copyright (c) 1998-2005 Julian Smart, Robert Roebling et al

Everyone is permitted to copy and distribute verbatim copies
of this licence document, but changing it is not allowed.

Interestingly, Lazarus license is a workaround to an incompatibility between GPL and the old MPL license.
Such problems that have been solved since the release of MPL 2.0.

Good idea.
Does it also return something?

Good to hear you found a place Josh!

People please, leaving all rethoric aside, this is not the biggest problem now, it's just icing on the cake.

Of course, it could become a bigger problem if the situation changes, but nobody is going to lose their house in a lawsuit.

Clearly state the license you prefer, and if you are really concerned, try to reach an agreement.

If this topic drowns into the flames of political argument, any possible solution will go down with it.

Reach agreement. Solve problem. Situation better.
Everybody happy.
