Irrlicht Engine

Finished build of irrlicht 1.9 (i.e. current trunk), with opengl/sdl1 support on amigao4 (so big endian CPU).

So far all good, but found some little issues, which maybe just one issue.

For first, 06.2Dgraphics example give me that:

As can be seen the area which should be transparenty just purple. In the source of that example we see:

video::ITexture* images = driver->getTexture("../../media/2ddemo.png");
driver->makeColorKeyTexture(images, core::position2d<s32>(0,0));

There is Texture is read back, and then the color key is applied to make it transparent. So guess is, that the colorkey is not detected correctly in the image because of the endianness.

Both version of the method makeNormalMapTexture from class CNullDriver (that will be used in the OpenGL driver), use some masking of the colors that seems LittleEndian to me.


const u32 refZeroAlpha = 0x00ffffff & color.color;
on
const u32 refZeroAlpha = 0xffffff00 & color.color;


if(((*p) & 0x00ffffff) == refZeroAlpha)
on
if(((*p) & 0xffffff00) == refZeroAlpha)


colorKey = 0x00ffffff & p[colorKeyPixelPos.Y*pitch + colorKeyPixelPos.X];
on
colorKey = 0xffffff00 & p[colorKeyPixelPos.Y*pitch + colorKeyPixelPos.X];

But sadly, that change nothing. Probably some other place should taken care of. Can anyone give a point to where to look at ?


And another issue, is with GUI. Every example which have GUI in, have problems with "gadgets". I.e. those "mark", "dropdown" , "left", "right", etc. Instead of proper ones, i have just black quads. Just like that (see menu at top, dropdown menu, navigate menu):

Probably can be same kind of issue with colorkey ..

Any help apprecated, thanks !

To add, issue with 06.2Dgraphics example happens and with opengl renderer and with burning video one, but all looks correct in software renderer. So its something which share opengl and burning, but not software. What it can be ?:)
