2D images? did you mean textures?
textures are managed by the IVideoDriver.
you don't need to wory about them.

ui2dimg is ITexture*

maybe i can't clear deliver oneself of idea.

the 2d picture is menu's background.

when i choose some game, i need clear out currently all background & menu.
i use device->getVideoDriver()->removeTexture(ui2dimg); remove 2dimg,but,scene always show the 2d background.

draw2DImage is driver-level rendering, and is not a GUI widget. Try using IGUIImage.

giuEnvironment->clear();

If you don't want to draw ui2dimg, you need to avoid calling driver->draw2DImage(ui2dimg, ...). The easy way would be to write something like this...

Code: Select all

if (ui2dimg)
  driver->draw2DImage(ui2dimg, position2di(0, 0));

Instead of removing the texture from the texture cache, you would write this...

Code: Select all

//device->getVideoDriver()->removeTexture();
ui2dimg = 0;

Even easier would be to use an IImage.
