drawing 2d rectangles

[me_go_fast]

I want to use a 2d rectangle as a health bar in game. But when i try to draw a 2d rectangle it doesn't sahow up in game. Here is the code i use:

while(SPDevice->run() && Sdriver)
{
Sdriver->beginScene(true, true, video::SColor(0,100,100,100));
smgr->drawAll();
env->drawAll();
core::position2d<s32> m = SPDevice->getCursorControl()->getPosition();
Sdriver->draw2DRectangle(SColor(0,100,100,100),rect<s32>(50,50,25,25), 0);
Sdriver->draw2DImage(texture, core::position2d<s32>(m.X - 12,m.Y - 12), rect<s32>(0,0,25,25), 0, video::SColor(255,255,255,255), true);
Sdriver->endScene();
}
SPDevice->drop();

If you can help me it would be appreciated. This is probably small mistake that i made but i can't find it!

SColor(0,100,100,100) is wrong. You set the alpha-value (first value) to 0 which means no visibility. Set it to 255 for full opacity.

[StargateSG1]

However the documentation says for SColor() alpha value that:

The alpha component defines how transparent a color should be. 0 means not transparent(so it's opque and is fully seen on screen), 255 means fully transparent(unseen).

Are the docs lieing

Sdriver->draw2DRectangle(SColor(0,100,100,100),rect<s32>(50,50,25,25), 0);
Sdriver->draw2DImage(texture, core::position2d<s32>(m.X - 12,m.Y - 12), rect<s32>(0,0,25,25), 0, video::SColor(255,255,255,255), true);
Sdriver->endScene();
}

it seems that you replaced values inf rect<s32>. if you'll put (25,25,50,50) instead it will probably be OK.
also, as far as I remeber SColor(255, 255, 255, 255) if fully white and opaque, so that's probably good choice for testing.

I tried using just the 2D rectangle and it seems that the rectangle is showing up behind the 3d Scene....

So if I have a simple plane with some stuff on it , the rectangle shows up behind the 3D objects....

driver->draw2DRectangle(SColor(100,255,255,255),rect<s32>(10,10,240,60),0);

Here's my code if I change the size of the object to be towards the middle of the screen it shows me that the rectangle is behind the 3d Objects...

Weird????

this looks like a bug to me...

smgr->drawAll();
env->drawAll();
Sdriver->draw2DRectangle(SColor(0,100,100,100),rect<s32>(50,50,25,25), 0);


take me lightly... in my program I have that minus the smgr which is what 3d?

ok so the solution seems to put the rectangle before you draw the smgr.. but doesn't env-> have to be before rectangle and after smgr?

you have all officially confused me.
