Hi guys, I've had a bit of experience programming 2D games in SFML and wanted to try out 3D programming using 3DVIA but im having some trouble getting started.

In 2D programs, you would create an image and display it as a "menu", get input and then act accordingly.
Usually, your "MainMenu", "HowToPlay", "Options" etc. are different classes which you call upon according to the user selection.
In 3DVIA Studio, I created each of these different Classes as an individual Stage on its own. However, after getting the mouse selection input using VSL scripting, I do not know how to call upon these different stages.

I then tried making it all into one stage with 2D textured nodes layered on top of each other, and an according click to make the respective screen visible and the rest not. But once the first screen goes, I do not know how to call on the Task/Behaviour for the second screen to make it active, so that it will get input to continue the application.

Is there anybody who can help me with this?

Hi Zuryx,

I'm not sure I've fully grasped what you aim to do.
Are you talking about designing a Menu system for your game ?

If so, I think using layered 2D Textured nodes could work.
I don't think it's the purpose of Stages to handle such tasks.

Have you think about events ?
I mean, what if you use an event to call a function that shows the Main Menu, another event to call a function that shows the Options, and so on ?

Hey HiddenTux,

Yes thats what I'm referring to, a menu system.

I have been using 2D textured nodes layered on top of each other. The problem with that is if you have a splashscreen which says "press any button to continue" and your user clicks on an area that is a event "triggerzone", it acts on the node behind the layers as well. So if i click on the options button that is behind the splashscreen, it goes straight to the options menu and skips the main menu.

The reason behind this is because all behaviours are made "active at present". However, if I do not enable this, once I click on the splashscreen, it goes to the MainMenu and gets stuck there because I can't find a function to make the MainMenu behaviour active when the splashscreen is gone. I hope I'm making some sense. Thanks for trying to help =)

There's two ways I can see to solve that problem:

1) As you mentioned, toggle the activity of the behaviors of the 2D nodes. You should be able to do this through the "vkComponent::Set Activity" or "vkComponent::Set Ring Activity" (if you are not familiar with the concept of component rings in Studio, check out this article: http://www.3dvia.com/studio/documentation/user-manual/content-management/property-view/actor-and-template-properties )

2) Toggle the activity of the "Pickable" on your 2D node (vkNode2D::Set Pickable). This will toggle on/off whether the mouse will be able to "pick" the 2D frame or not.

Is this the kind of stuff you are looking for?
