[SOLVED] New Sets Of Widgets via Plugin

[marc.jamero.ph]

I'd like to create new sets of widget(i.e. WidgetInventory) via a plugin. Is it possible? If yes, how exactly can it be done? To make things clear, an Inventory Widget consists of let's say, 3 buttons, 1 listbox and a sprite.

 

WidgetButton

WidgetListBox

WidgetSprite

 

There, I need those Widgets to use inside the DLL Project using C++ via the C++ API and produce a plugin. In other words, I want to make a new WidgetInventory by using the default Widgets like WidgetButton in the form of a plugin.

Hi,

 

You can't inherit from classes like Nodes, Widgets, etc. on C++ side. But you can extend them from UnigineScript.

 

Please read this topics for additional information:

I have linked my C++ project to the C++ API and to the Unigine source. but I think Widgets are not exported out on the .dll right? that's why I can't make a plugin that will add Widgets like for example WidgetInventory.

Is there any other way to access the core classes(widgets,nodes) using C++ aside from modifying the source of the Unigine?

No, you can't inherit without modifying the source.

 

You can extend widgets/nodes/etc. in four different ways:

 

1. (C++ side, unlikely) Modify engine source and inherit you classes from original Widget/Node

2. (Unigine script) Inherit from extern 'Widget' class provided by C++ part

3. (Unigine script) Write custom wrapper class on one of currently available widgets (for example, buttons in Oil Rush is a custom wrapper on WidgetSprite class)

4. (Unigine script) Inherit from core/systems/widgets Widget class
