Irrlicht Engine

This is an extremely simple question, and I feel kinda dumb for asking it, but there was NOWHERE where I was able to find an answer to this simple question. I did about 10 different searches and even in the wiki it does not come up.

In the tutorials, this code is used quite often:

Code: Select all

        // add irrlicht logo
        env->addImage(driver->getTexture("../../media/irrlichtlogo2.png"),
                core::position2d<s32>(10,10));

I like how simplistic it is to add an image to the screen, but I want to be able to make the image transparent, yet I can't find the code.

It's probably a really simple line that I'm just constantly skipping over, but I just can't seem to find it! What is it?

Just change the alpha of the image color and tell the draw2dimage to take vertex alpha into account.

Hmm, well I just stuck with making the image transparent in Photoshop which worked for me.

Ok, this won't enable simply change of the transparency at runtime, though, but it also works as expected
