2D Graphics Drawing HUD

[mubashar]

I am working on racing game project now its time to draw hud to show racing meter .. i am using two transparent images

Code: Select all

ITexture* image_meter = driver->getTexture("media/2D/speedometer_base.png");
ITexture* image_needle = driver->getTexture("media/2D/speedometer_arrow.png");material.MaterialType = irr::video::EMT_TRANSPARENT_ALPHA_CHANNEL;
                  driver->setTransform(irr::video::ETS_VIEW,irr::core::matrix4());
                    driver->setTransform(irr::video::ETS_PROJECTION,irr::core::matrix4());
                  driver->setMaterial(material);
                driver->draw2DImage(image_meter,vector2d<s32>(RX/1.15,RY/1.2),rect<s32>(0,0,image_meter->getSize().Width/2,image_meter->getSize().Height/2),0,SColor(255,255,255,255),true);
                driver->draw2DImage(image_needle,vector2d<s32>(RX/1.15,RY/1.2),rect<s32>(0,0,image_needle->getSize().Width/2,image_needle->getSize().Height/2),0,SColor(255,255,255,255),true);

Now what i want to do is rotate "image_needle" and i have no idea how can i do this i have read 2d graphics tutorial but didn't help so can any one please help me here .... i just want to know how to rotate image than i will adjust its value with speed .... thank you

An oop way is to subclass gui::IGUIElement.

You may take a look at vitek's CGUICompass for example:
