[SOLVED] Can't get ObjectGui + WidgeSpriteVideo to work in C++

[joseph.howell]

Hi, I'm trying to implement ObjectGui + WidgetSpriteVideo in C++, following the example in gui_00.  So far, nothing shows up.

 

Here's my initialization code:

 

objectGui = ObjectGui::create(20.0f, 15.0f);

 

objectGui->setTransform(Mat4(translate(0.0f, 0.0f, 8.0f) * rotateY(90.0f) * rotateZ(90.0f)));

 

objectGui->setMaterial(lookupId.c_str(), "*");

objectGui->setProperty("surface_base", "*");

objectGui->setMaterialState("mode", 1, 0);

 

GuiPtr gui = objectGui->getGui();

sprite_video = WidgetSpriteVideo::create(gui, "resources/data/sanctuary.ogv");

gui->addChild(sprite_video->getWidget(), Gui::ALIGN_EXPAND);

 

sprite_video->setVideoTime(0.0f);

sprite_vide->play();

 

 

If I replace my gui pointer with the regular GUI, then it works as expected and I can see the video playing, but it takes up the whole screen.

 

//replace this one line and it works on the whole screen gui

GuiPtr gui = Gui::get();  //objectGui->getGui();

 

So it's like I can't see the ObjectGui I created.  Even though I know my camera is at the origin when I start up, and it should be putting that ObjectGui around the origin too.  I have flown around, trying different camera angles just in case the ObjectGui was back-facing.  It doesn't show up from any angle.

 

Suggestions?

 

Thanks

I put nearly identical code in my script file (but adapted to UnigineScript of course) and it works... does ObjectGui only work from script?

 

-- Update -- 

 

I also got ObjectGui working with WidgetSprite in C++.  For some reason, I just can't get WidgetSpriteVideo working.  But it looks like I can use WidgetSprite for my needs.

Hi Joseph,

 

I've just tested this in c++ and it is working fine, here is code sample:

objectGui = ObjectGui::create(20.0f, 15.0f);
objectGui->setTransform(Mat4(translate(0.0f, 0.0f, 8.0f) * rotateY(90.0f) * rotateZ(90.0f)));

objectGui->setMaterial("gui_base", "*");
objectGui->setProperty("surface_base", "*");
objectGui->setMaterialState("mode", 1, 0);

GuiPtr gui = objectGui->getGui();
sprite_video = WidgetSpriteVideo::create(gui, "data/unigine.ogv");
gui->addChild(sprite_video->getWidget(), Gui::ALIGN_EXPAND);

sprite_video->setVideoTime(0.0f);
sprite_video->play();

From your code I would check, if object gui's material in lookupId variable is derived from gui_base ?

[joseph.howell]

The only thing I see different is the "gui_base" for the material.  The lookup id value was for a material I derived from "mesh_base", maybe that was the problem.  I'll try making that change when I get the chance,

 

But for now, the WidgetSprite is doing what I need.  I'm streaming video from a webcam, so I need to update the image in the WidgetSprite each frame.  So I don't think WidgetSpriteVideo is the right fit for me.

 

Thanks
