Hi,

I want to render MyGUI UI(HUD) on OGRE Mesh using RTTLayer, But it seems that not possible to create new RTT layer from Code? Any idea?

Thanks for your help.

I know this post is old, but I have the same question. I want to add in-game UI-Screens (which works find already, using RTT-Layers), but I don't know how many I will need before starting the game.

How do I create new layers on-the run?

I am looking for a function like
LayerManager::createLayer( ... );

The closest thing I can find is to copy the stuff you do in LayerManager::_load(), but that would mean I have to construct the layer as an XML first, which is kind of ugly.

P.S. There has been a similar question to this before: viewtopic.php?f=17&t=14776&p=82465&hilit=layer+c%C3%BC%C3%BC+create+layer+c+#p82465
But the answer is "Sure, and this is shown in the wiki page" - but I've gone through all wiki pages and found nothing so far.

I think I am getting somewhere using the FactoryManager's "createObject" class.

Initializing MyGUI:



#if OGRE_VERSION_MAJOR >= 1 && OGRE_VERSION_MINOR >= 9

	Ogre::OverlaySystem* pOverlaySystem = new Ogre::OverlaySystem();

	sceneMgr->addRenderQueueListener(pOverlaySystem);

#endif

	mPlatform = new MyGUI::OgrePlatform();

	mPlatform->initialise(window, sceneMgr);

	mGUI = new MyGUI::Gui();

	mGUI->initialise( "My_Core.xml" );



	std::string layerCategory = MyGUI::LayerManager::getInstance().getCategoryName();

	MyGUI::FactoryManager::getInstance().registerFactory<MyGUI::RTTLayer>(layerCategory);



	MyGUI::ResourceManager::getInstance().load("HologramLayers.xml");

Then I try to create a layer, a texture, and an object.
The object displays the texture and I link the texture to the layer.
The object stays black, and when I try to save the picture to disk it turns out it's an empty transparent texture.





	MyGUI::IObject* mObject = MyGUI::FactoryManager::getInstance().createObject(

			"Layer", "RTTLayer" );



	MyGUI::RTTLayer* layer = mObject->castType<MyGUI::RTTLayer>(false);



	MyGUI::ButtonPtr newButton = mGUI->createWidget<MyGUI::Button>("NormalButton",

			0, 0, MAIN_HOLOGRAM_WIDTH, MAIN_HOLOGRAM_HEIGHT,

			MyGUI::Align::Default, layer->getName() );

	newButton->setCaption("Test");



	layer->createChildItemNode()->attachLayerItem( newButton );



	Ogre::TextureManager::getSingleton().createManual(

		"AwesomeUITexture",

		Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME,

		Ogre::TEX_TYPE_2D,      // type

		255, 255, 1,      // width & height & depth

		0,                // number of mipmaps

		Ogre::PF_BYTE_RGBA,     // pixel format

		Ogre::TU_RENDERTARGET);      // usage;



	Ogre::MaterialPtr mat = Ogre::MaterialManager::getSingleton().getByName("UI");



	mat->getTechnique(0)->getPass(0)->getTextureUnitState(0)->setTextureName( "AwesomeUITexture" );



	layer->setTextureSize( MyGUI::IntSize( 255, 255 ) );

	layer->setTextureName( "AwesomeUITexture" );



	// Create ManualObject and apply the material/texture to it:

	Ogre::ManualObject* mMesh = mSceneMgr->createManualObject("UiManual");

	mMesh->begin("UI", Ogre::RenderOperation::OT_TRIANGLE_LIST);



	float z = 0;

	float texZ = 0;

	float width = 0.5;

	mMesh->position(-width*0.5, -width*0.5, z);

	mMesh->textureCoord( 0.0, 0.0, texZ );

	mMesh->position( width*0.5, -width*0.5, z);

	mMesh->textureCoord( 1.0, 0.0, texZ );

	mMesh->position( width*0.5,  width*0.5, z);

	mMesh->textureCoord( 1.0, 1.0, texZ );

	mMesh->position(-width*0.5,  width*0.5, z);

	mMesh->textureCoord( 0.0, 1.0, texZ );



	mMesh->index(0); mMesh->index(1); mMesh->index(2);

	mMesh->index(0); mMesh->index(2); mMesh->index(3);



	mMesh->index(2); mMesh->index(1); mMesh->index(0);

	mMesh->index(3); mMesh->index(2); mMesh->index(0);



	mMesh->end();

	mNode->attachObject(mMesh);

When I exchange the texture with a .png file it shows that on the mesh just like expected.

Edit: Here's my Log. It's interesting how, when destroying the layermanager, there are ONLY the layers which I created in an xml file. The one I manually create doesn't even show up.
I tried printing the return value of MyGUI::LayerManager::getInstance().getLayerCount() and it stays the same when I create a new layer using the above method. So this isn't working...?

Unfortunately MyGUI doesn't have API for proper runtime resources creation.
Currently the only way how you acn add such layer in runtime is load xml, either from file or from xml created in code.

There are no issues or architecture limits for adding such functionality, it just never was done. I'll try to implement this now.

Done. Try to update to latest source from github and use LayerManager::createLayerAt

It works!

Thank you so much.
It took me a while to get all the function calls in the right order. Also, I did not know MyGUI's RTTLayer actually created the render-texture itself, so I kept trying to create the texture myself using Ogre's TextureManager and then assign that - which wouldn't work, of course.

Since it took me so long to get it all together, I thought I'd post the working code for anyone else to use:





	// mNode is going to be the node to attach a 3D mesh to, which will display the

	// new layer.

	mNode = node->createChildSceneNode();



	// Create a new RTT Layer

	MyGUI::RTTLayer* layer = (MyGUI::RTTLayer*)MyGUI::LayerManager::getInstance().createLayerAt(

			"MyNewLayer", "RTTLayer", 0 );



	// BOTH setTextureName AND setTextureSize MUST be called:

	layer->setTextureName( "MyNewTexture" );

	// This second call will actually create the texture. If you have not called setTextureName

	// before then this will create a (seemingly random) name for the texture -> then you won't

	// be able to use it!

	layer->setTextureSize( MyGUI::IntSize( 255,255 ) );



	// Create a test button on the new layer.

	// Note: Beforehand, you must initialize mGUI as usual, loading a Theme/Scheme with

	// button Definitions etc. I loaded one which defines a button type called "NormalButton".

	// Change that to whatever widgets you would create, just like you would on a normal Layer.

	MyGUI::ButtonPtr newButton = mGUI->createWidget<MyGUI::Button>("NormalButton",

			0, 0, 150, 50,

			MyGUI::Align::Default, "MyNewLayer" );

	newButton->setCaption("Test");



	// Assign the texture to the "UI" material. In a real-world scenary, "UI" would be

	// created at runtime - for example by copying another material - for every panel

	// which is created:

	Ogre::MaterialPtr mat = Ogre::MaterialManager::getSingleton().getByName("UI");

	mat->getTechnique(0)->getPass(0)->getTextureUnitState(0)->setTextureName( "MyNewTexture" );



	// Create a 3D object to display the stuff on. It's a simple two-sided square, but could

	// be any other object/mesh as well.

	Ogre::ManualObject* mMesh = mSceneMgr->createManualObject("UiManual");

	// The object uses the "UI" Material:

	mMesh->begin("UI", Ogre::RenderOperation::OT_TRIANGLE_LIST);



	float z = 0;

	float texZ = 0;

	float width = 0.5;

	mMesh->position(-width*0.5, width*0.5, z);

	mMesh->textureCoord( 0.0, 0.0, texZ );

	mMesh->position( width*0.5, width*0.5, z);

	mMesh->textureCoord( 1.0, 0.0, texZ );

	mMesh->position( width*0.5,  -width*0.5, z);

	mMesh->textureCoord( 1.0, 1.0, texZ );

	mMesh->position(-width*0.5,  -width*0.5, z);

	mMesh->textureCoord( 0.0, 1.0, texZ );



	mMesh->index(0); mMesh->index(1); mMesh->index(2);

	mMesh->index(0); mMesh->index(2); mMesh->index(3);



	mMesh->index(2); mMesh->index(1); mMesh->index(0);

	mMesh->index(3); mMesh->index(2); mMesh->index(0);



	mMesh->end();



	// Add the mesh to the scene:

	mNode->attachObject(mMesh);

Edit: i'm thinking of putting this into the Ogre Wiki as well. Seems like many people have been asking for this, or similar things.
