How to set rotation of an object about its center or about one specific point?

I use this code to create an arrow mesh.
Now, I would like to change its color, but I cannot find any API to do that.
What should I do?

Now I can do this http://img.photobucket.com/albums/v252/wongsiwai/ScreenHunter_01Feb060028.jpg But now, the problem for me to handle is to let the program now I am clicking on one of the arrows to perform object translation about one of the axes. I think I need to add another collision manager for ...

This can solve!!!

Hey!!! It seems the arrow is in front of the cube now:D But......I still dont know why the texture cannot be loaded in smgr2 =,= #include <irrlicht.h> using namespace irr; using namespace core; using namespace scene; using namespace video; using namespace io; using namespace gui; #ifdef _IRR_WINDOWS...

Anthony,
have you run the code?

Do you know why the texture cannot be loaded in smgr2.....?

I think using separate scene manager may not do the job. Using 2 scene managers means there should be 2 cameras. So confused -,- #include <irrlicht.h> using namespace irr; using namespace core; using namespace scene; using namespace video; using namespace io; using namespace gui; #ifdef _IRR_WINDOWS...

You need to render the arrows last (maybe using a separate scene manager) and disable zbuffer test :shock: It seems complicated..... Should I use the code below to use a separate scene manager? smgr2 = smgr1->createNewSceneManager() Is that what you mean by disabling zbuffer for the arrow? ISceneNo...

If you call drawMeshbuffer or draw3dVertexPrimitiveList instead it should also work. When setting the viewport to the whole screen (or a rather huge part of it) you won't notice too much change. That call is not necessary for your purpose, so simply skip it. Sorry....in fact, I havent solved this p...

http://www.3dmodelfree.com/3dmodel/list403-1.htm I have downloaded a 3d model from this site. And then I open the model in 3ds max, then export it to .3DS format. After loading the .3ds in Irrlicht, the object looks strange http://img.photobucket.com/albums/v252/wongsiwai/ScreenHunter_01Feb051526.jp...

I notice that img->setImage(texture); will not take into effect if the 1st parameter in addImage() is a null pointer.

Dont know why = =

I can see the image using this code. ITexture *texture = driver->getTexture("../../media/fire.bmp"); IGUIImage *img = guienv->addImage(texture, core::vector2d<s32>(300,300), false); But I can't see the image using that code ITexture *texture = driver->getTexture("../../media/fire.bmp&...

if (listBox->getListItem(listBox->getSelected()) == L"ABC") Device->closeDevice(); In a list box, I have added an item called "ABC" So, if I select "ABC", the device should be closed but it is not the case.... Is there something wrong in the if statement?

If the button is added in a toolbar, I can apply an image to it.
But if the button is added by the gui environment, I can't do that.

How to solve that problem?

But example 5 does not show how to get the option that the user chose.
There are 2 possible options in the list box in example 5, which are "File open" and "Window created".

If the user clicks on window created, how can I know?
What should I do in the event receiver?
