MyGUI in Ogre RTT and direct call texture display

After using MyGUI,

It is good to use, but I found a problem with too little information,

No way, you can only chew on the code,

Here we will talk about the use of MyGUI:

1. RTT rendering to texture:

This is very simple. First, confirm the Canvas to be displayed in Layout,

Get it in the program

MyGUI: Canvas * canvas2;
AssignWidget (canvas2, "SceneAddView ");

Then assign it to a RenderBoxScene

Wraps: RenderBoxScene mRenderBoxScene;
MRenderBoxScene. setCanvas (canvas2 );

Insert Mesh again, OK

(If there is a problem in Debug, refer to the previous article. I hope there will be Q & A in brick shops)
MRenderBoxScene. injectObject ("Robot. mesh ");
MRenderBoxScene. setAutoRotation (true );
MRenderBoxScene. setMouseRotation (true );

2. directly use the texture in Ogre

To display a Real-Time Ogre texture in an ImageBox,

First of all

MyGUI: ImageBox * mAtlasView;

MyGUI: OgreTexture * mTexture;

AssignWidget (mAtlasView, "AtlasView ");

Then you need to specify the texture at the Tex manager of Ogre,

Ogre: TexturePtr layer0 = Ogre: TextureManager: getSingletonPtr ()-> getByName ("<TileImagesetTexture> ");

Here it is transitioned and assigned to a MyGUI OgreTexture. It is not clear about other usage, so we can only use this hack for the time being.

MTexture = (MyGUI: OgreTexture *) MyGUI: RenderManager: getInstance (). createTexture ("AtlasView ");

MTexture-> setOgreTexture (layer0 );

Set the size of a specific texture

MyGUI: IntCoord coord (0, 0, 1024,128 );

And the size of each small image (if you want to display the entire image, you can directly coord. size ())
MyGUI: types: TSize <int> tileSize (64, 64 );

Here, I do not know why MyGUI does not initialize the Index through the setImageInfo initialization method,

If the following line is not added, the image cannot be displayed.
MAtlasView-> setItemSelect (0 );
MAtlasView-> setImageInfo ("AtlasView", coord, tileSize );

3, PS:

MyGUI is native to support OIS, there are options in CMake, just set it, the practice in the previous article is too painful.

Attached is the architecture diagram of MyGUI.
