Draw2DImage error

[Mercator]

I want to draw an image with varying transparency, but I get an error when I use the SColor parameter.

This compiles well:

Code: Select all

m_driver->draw2DImage(m_buf[id].img, dest, m_buf[id].src, NULL, NULL, true);

This does not:

Code: Select all

m_driver->draw2DImage(m_buf[id].img, dest, m_buf[id].src, NULL, SColor(255,255,255,255), true);

Code: Select all

error: no matching function for call to `irr::video::IVideoDriver::draw2DImage(irr::video::ITexture*&, irr::core::rect<irr::s32>&, irr::core::rect<irr::s32>&, NULL, irr::video::SColor, bool)'

What did I do wrong?

You are using the last one of the candidate methods the compiler mentioned. As you can see it does not take a video::SColor but a video::SColor*. It is a pointer to four colors, specifying the colors of each corner of the image you are drawing. So do like this:

Code: Select all

video::SColor colors[4] = {video::SColor(255,255,255,255), video::SColor(255,255,255,255), video::SColor(255,255,255,255), video::SColor(255,255,255,255)};
m_driver->draw2DImage(m_buf[id].img, dest, m_buf[id].src, NULL, &colors[0], true);

Thank you!
