Hi. How I can use 2D images (.jpg) in my game? I'd like make a main manu, I have strings, but I 'd like have background in main menu. How I can use images?

Have a look at Billboards
Do a search for Billboards

Some code to get you looking in the right direction



BillboardSet mJpgSet = sceneMgr.CreateBillboardSet("JpgsEx");

mJpgSet.SetMaterialName("YOUR MATERIAL HERE");

mJpgSet.CullIndividually = true;

mJpgSet.QueryFlags = 0;	// They should not be detected by rays.



mNode.AttachObject(mJpgSet);

// where mNode is your SceneNode you want to attach to, could be your default main node the camera is attached to.



// -------------------------------

// Creation of the billboards

// -------------------------------

Billboard Picture = mJpgSet.CreateBillboard(0, 0, 120);

Picture.SetDimensions(10, 10);

It's my code:

BillboardSet mJpgSet = Engine.Singleton.SceneManager.CreateBillboardSet("JpgsEx");

                    mJpgSet.SetMaterialName("Vase/TEXFACE/vase.jpg");

                    mJpgSet.CullIndividually = true;

                    mJpgSet.QueryFlags = 0;   // They should not be detected by rays.

                    SceneNode mNode = new SceneNode(Engine.Singleton.SceneManager);

                    // where mNode is your SceneNode you want to attach to, could be your default main node the camera is attached to.



                    // -------------------------------

                    // Creation of the billboards

                    // -------------------------------

                    Billboard Picture = mJpgSet.CreateBillboard(2, 2, 2);

                    Picture.SetDimensions(10, 10);

But I can't see thia image. What is bad?

You need to attach it to the node



mJpgSet.SetMaterialName("Vase_Texface");  // Material name NOT jpg file

mNode.AttachObject(mJpgSet);  // this line seems to be missing in your code, plus ensure you have a scenemanager and camera set up!

Add your jpgs to the Media\materials\textures folder

Create a material file in
Media\materials\scripts



material Vase_Texface

{

   technique

   {

      pass

      {

         texture_unit

         {

            //texture "vase.jpg"

            texture "Your Jpg name.jpg"

         }

      }

   }

}
