[2.2] How to compile MyGUI for Ogre 2.2

[Lax]

Hi together,

I wanted to ask, if someone already ported the MyGUI Engine to Ogre2.2?
I get a lot of erros in Ogre2Platform project, because textures and compositors api has of course changed.

Best Regards
Lax

rujialiu I summon you!
he helped me with that task, and prefer if he shares it.
rujia, maybe you could make a branch/fork on the official myGui repo?

[al2950]

Arggg. I was also helped by rujialiu, but I did say I would create a PR with my changes but have failed to do that. I am not sure my approach to the changes is the most universal, but maybe I should at least make them public. I ve put it off because it requires git, which just irritates me! Ill try and find time this weekend

Hi al2950,

that would be great!

haha, I was too lazy and hoped that al2950 would find sometime to publish the changes earlier than I do...

That would be very nice. Even if your changes are not most universal, it must be better than what I originally sent you

[al2950]

Sorry, failed to do this last weekend. I will try Friday. Please just keep pestering me!

[Lax]

Hi al2950,

you asked to pestering you
Is there any progress?

Best regards
Lax

[al2950]

ok, so it turns out I was even lazier than I thought. I think i took rujialiu changes and made them less sensible! I would really like to sort this properly so there is 1 ogre branch in mygui, with as much shared code as possible. This will obviously take a little while, and might be too messy to actually do. in the meantime I have uploaded what I currently use for 2.2:

Thanks a lot!
At least it compiled

Hello! I have MyGui working with Ogre 2.2 and OpenGL... the main usage for my is to render gui in to a texture that I use on some object inside the 3D scene.
Now I am porting my engine to Direct3D11 and all the MyGui stuffs don't show on the objects on the scene but it shows on the main render window :S

I am giving the correct texture when I call addWorkspace, and checked that the workspace has indeed the correct texture when update is being called. Also checked on renderdoc that the correct texture is not being filled with the gui image.

anyone else is using MyGui to render in to an Ogre 2.2 texture?

thanks!

Now I am porting my engine to Direct3D11 and all the MyGui stuffs don't show on the objects on the scene but it shows on the main render window :S

solved this problem thanks to dark_sylinc, by changing MyGUIPass::execute to this:

Code: Select all

	void MyGUIPass::execute(const Ogre::Camera *lodCameraconst)
	{
        profilingBegin();
        executeResourceTransitions();
        setRenderPassDescToCurrent();
		static_cast<MyGUI::Ogre2RenderManager*>(MyGUI::RenderManager::getInstancePtr())->render();
        profilingEnd();
	}

plus some profiling stuffs

thanks!

[dark_sylinc]

The order of executeResourceTransitions and setRenderPassDescToCurrent was inverted!

setRenderPassDescToCurrent must be called first!
executeResourceTransitions is only relevant for Metal.

A gentle reminder: the latest commit breaks a few API. In order to compile MyGUI, you need a simple change:

The line might not match because I'm using my own MyGUI branch.

Hi all,

was someone able to adapt MyGUI to newest Ogre2.2 version from github?
Now some includes cannot be found anymore:

Code: Select all

#include <OgreTextureManager.h>
#include <OgreTexture.h>
#include <OgrePixelBox.h>
...

They have been moved to "deprecated" folder. When this folder is prefixed, other errors do occur.

Another question, what happened to RenderWindow? It is no more available...

Best Regards
Lax

[dark_sylinc]

Hi!

This was all deadcode, so if the code was fully running on Ogre 2.2 it is very likely that just removing those includes is enough to make things running again.

If for some reason that's not the case, then the header files are still included on the Deprecated folder and add that folder to the list of include_headers so that they can be found by the compiler

[Lax]

Hi,

This was all deadcode, so if the code was fully running on Ogre 2.2 it is very likely that just removing those includes is enough to make things running again.

Unfortunately not.

I could replace "OgreTextureManager" with "OgreTextureGpuManager" etc.

Trying to compile MyGUI I found other issues:

- Ogre::TextureUsage is also no more available:

Code: Select all

Ogre::TextureUsage Ogre2Texture::convertUsage(TextureUsage _usage)
	{
		if (_usage == TextureUsage::Default)
		{
			return Ogre::TU_STATIC_WRITE_ONLY;
		}

That can be COMPLETELY removed. That function, and the mUsage member variable, because they're not used anyway. Only MyGUI's own usage (_usage) is used. When creating a manual texture, we can directly query _usage instead of mUsage.

In case your MyGUI code used it (I'm using my own branch so it's possible that your MyGUI branch is still using it), here is my createManual function:

Code: Select all

void Ogre2Texture::createManual(int _width, int _height, TextureUsage _usage, PixelFormat _format)
    {
        setFormat(_format);
        setUsage(_usage);
        uint32 textureFlags = 0; // Ogre::TextureFlags::PrefersLoadingFromFileAsSRGB
        if (_usage.isValue(TextureUsage::RenderTarget)) {
            textureFlags |= Ogre::TextureFlags::RenderToTexture;
        }
        // TODO: Ogre::TextureFlags::Manual

        Ogre::TextureGpuManager *textureMgr = Ogre::Root::getSingletonPtr()->getRenderSystem()->getTextureGpuManager();
        mTexture = textureMgr->createOrRetrieveTexture(
            mName,
            Ogre::GpuPageOutStrategy::Discard,
            textureFlags,
            Ogre::TextureTypes::Type2D,
            Ogre::ResourceGroupManager::
            AUTODETECT_RESOURCE_GROUP_NAME);
        
        if (mTexture) {
            mTexture->setResolution(_width, _height);
            mTexture->setPixelFormat(mPixelFormat);
        }

        if (_usage.isValue(TextureUsage::RenderTarget)) {
            textureFlags |= Ogre::TextureFlags::RenderToTexture;
            if (mTexture->getNextResidencyStatus() != Ogre::GpuResidency::Resident) {
                mTexture->_transitionTo(Ogre::GpuResidency::Resident, nullptr);
                mTexture->_setNextResidencyStatus(Ogre::GpuResidency::Resident);
            }
        }
        setDataBlockTexture(mTexture);
    }

Trying to compile MyGUI I found other issues:

But... if you already updated to the latest commit or latest this one: https://github.com/OGRECave/ogre-next/c ... f3d539bc48

After your code compiles, it's likely that it'll crash. That's because the with fixing issue 33, RenderQueue::frameEnded() has an assertion inside that expect every render() is followed by renderPassPrepare() AND no VaoManager::_update() is called in-between(). However, that means in MyGUI's Ogre2RenderManager::render(), you have to call renderPassPrepare before calling render(), like this:

Code: Select all

mSceneManager->getRenderQueue()->renderPassPrepare(false, false);
mSceneManager->getRenderQueue()->render(mSceneManager->getDestinationRenderSystem(), RENDER_QUEUE_OVERLAY, RENDER_QUEUE_OVERLAY+1, false, false);

That is likely breaking other codes as well. Is it intended, @dark_sylinc?

I took a detailed look: it looks like the assert accidentally caught a bad use. It's not a bug.

The function RenderQueue::renderPassPrepare must be called if you're calling RenderQueue::render.
In Ogre 2.1 the tasks performed by renderPassPrepare were being done inside RenderQueue::render.

IIRC we had to split them into two functions because of some Metal incompatibility with RenderPassDescriptors. Overlays were being naughty in their _updateRenderQueue calls (a v1 legacy stuff), and were forcing to breakup the close a RenderCommandEncoder too early in order to open a BlitCommandEncoder, so we had to move things around.

And thus we had to move things around. The current order of execution which must be honoured to work correctly in Metal:

1. Call RenderSystem::beginRenderPassDescriptor
2. Call Overlays' _updateRenderQueue (i.e. in fireRenderQueueStarted). You don't need to if you don't use Overlays. But if you need to copy GPU buffers around, then this still applies.
3. Call RenderQueue::renderPassPrepare
4. Call executeRenderPassDescriptorDelayedActions (which originally was inside beginRenderPassDescriptor)
5. Call RenderQueue::render

If you don't follow this order, you could get exceptions from either Ogre or Metal, or a performance warning in Ogre.log. If you don't get any exceptions or warnings, then it is very likely you were lucky the code was not doing anything that forced to breakup a RenderCommandEncoder, hence everything ran without issues.

Cheers

Update: I've pushed a documentation update to clarify this

Update: I've pushed a documentation update to clarify this

Oh, thanks! So the MyGUI code should also call renderPassPrepare BEFORE you wrote the assertions. I guess everyone here, like me, don't use MyGUI in Metal RS

I apologize for digging up this old thread but I have started working on converting my game from Ogre 2.1 to 2.2 and wanted to get MyGUI working.

I downloaded and attempted to build the 2.2 branch found on al2950's github page: https://github.com/al2950/mygui/tree/Ogre2.2. Then I applied some of the fixes from this thread and now I'm getting an error related to mTmpData which I had commented out since I had commented out the include for include OgrePixelBox.h:

Then I applied some of the fixes from this thread and now I'm getting an error related to mTmpData which I had commented out since I had commented out the include for include OgrePixelBox.h:

al2950's commit was in May 2019, then there were several other changes to Ogre. The biggest change should be the "deprecated" one (which caused OgrePixelBox.h to be removed in my version, and mTmpData changed to Ogre::uint8*), so it's normal that you can't compile Anyway, I'm attaching my personal changes after May 2019 (actually the first change happened in Sept. 2019). Since the diff is based on my version, not al2950, there maybe it's not 100% applicable to your case, so you need to make some adjustments.

Also, the diff looks long because part of my modification is to remove Ogre 2.1 support, but if you look at it carefully it should be easy to understand

Then I applied some of the fixes from this thread and now I'm getting an error related to mTmpData which I had commented out since I had commented out the include for include OgrePixelBox.h:

al2950's commit was in May 2019, then there were several other changes to Ogre. The biggest change should be the "deprecated" one (which caused OgrePixelBox.h to be removed in my version, and mTmpData changed to Ogre::uint8*), so it's normal that you can't compile Anyway, I'm attaching my personal changes after May 2019 (actually the first change happened in Sept. 2019). Since the diff is based on my version, not al2950, there maybe it's not 100% applicable to your case, so you need to make some adjustments.

Also, the diff looks long because part of my modification is to remove Ogre 2.1 support, but if you look at it carefully it should be easy to understand
