CEGUI (Crazy Eddie's GUI) Forums

Whenever I call the CEGUI::System::getSingleton().renderGUI(); function, the Depth buffer in my DirectX program becomes non-existant. Can anyone help me?

Version? Log? Are you using DX9/DX10/DX11 renderer?

Or are you trying to piss me off?

Forgot , Ok so DirectX9, Version 0.73,


I'll provide you with any more subsequent information that you need.

You should setup the DX state, draw your scene, then call renderGUI, then repeat. The DX9 renderer actually does this to the device in beginRendering():


At the beginning of your rendering code, you should reenable both I guess (very little DX9 experience on my side). CEGUI never uses z buffer during it's rendering, everything gets rendered as "always pass".

Cheers. I didn't find any information about the Renderer doing that Maybe you should add a little bit in the "Getting CEGUI rendering" just to warn users?

I think it's considered a common knowledge. You should never just use the state you are given in both DX and OpenGL. Controlling the state is necessary. Look what all CEGUI does to set it's rendering state... Once you set it, you can rely on what YOU yourself did.

However, feel free (and encouraged!) to add this to the wiki.

I'd be more than happy to add to the documentation, if I could ;P

http://www.cegui.org.uk/docs/current/re ... orial.html

If I COULD change it, I'd add probably add a few extra lines of code + commenting just notifying new users...

You can modify the doxygen-based tutorials by downloading the source-code, making appropriate changes (doc/doxygen/tutorials), and posting a patch that a developer can apply.

This is obviously not an ideal approach. I am not sure why CE moved the tutorials from the wiki to doxygen. Perhaps to distribute them with the source / make them available offline; imho this is not a sufficient reason. I think that doxygen should be reserved for code-documenting and the wiki for everything else (tutorials, examples, snippets, faq, how-to, etc.) so that any such issues can be resolved by the community. Perhaps we can convince CE to return the tutorials to the wiki? This may also be a chance to push support for the previously mentioned version badges

The tutorials were moved to the main documentation because this way things can remain self contained within a / the distribution. Experience has shown that while a Wiki has the potential to be a valuable resource, it's too easy for things to get out dated and/or confused as regards to versions. I agree that the Wiki version badges are indeed a good thing, though if these tutorials were still maintained on the Wiki, it would then mean having multiple versions of those hanging around, again adding to the confusion. The offline availability of the main docs is a major asset when either the site is having issues or the user does not have internet access (for whatever reasons).

In the future it's likely that more information will be included in the main docs, some of it will mirror or (more likely) obsolete articles currently on the Wiki. This is because such things can be generated automatically and be automatically included, indexed and cross referenced in the main docs, whereas Wiki-fied versions of the same require much more user intervention.
