[SOLVED] WidgetSpriteNode any code in samples that shows how to use WidgetSpriteNode

Hi 

 

WidgetSpriteNode

 

Any code in samples that shows how to use WidgetSpriteNode ?

 

Thanks

Hi Paul,

 

Please, check the render/node_00 and widgets/render_00 samples.

How about code which uses the update() method from the GUI rather than calling renderImage()  directly. (Otherwise I'm not sure why it's a Widget?)

Hi Greg,

What do you mean by update() method from GUI? Could you please give us more details (what task you are trying to solve, maybe sample test code)?

Thanks!

WidgetSpriteNode::update() gets called from the GUI if you addChild() like you normally would for a widget. And update() calls renderImage(). But the sample doesn't work that way, so an example of how that method works would be nice.

But it's not important for us any longer, we've figured out (roughly) what was going wrong for us - Unigine was silently ignoring cubemaps when we gave them in a slightly different DDS format, so it was rendering the widget's node with whatever environment map was the last one used in the previous frame!

Hi Greg,

Thanks for the feedback. We've try to create sample that will cover this topic.

Cool. Further to the above: It turns out we were supplying a texture array instead of a cubemap to WidgetSpriteNode::setEnvironmentTextureName() and it just silently failed to update the cubemap and forgot to unbind whatever cubemap had been bound by the previous draw call. (same thing happens if we try to bind a 2d texture)

So that looks like two related bugs (no error message and failing to unbind) in 2.3.1

Hi Greg,

Indeed, that's need to be filed too. I've created this bug in our internal bug tracker.
 

Thank you!
