Title: render window Clear to colour not working
Post by: slotdev on June 20, 2011, 02:03:13 pm

Hi

When I clear my render window, I want to fill it with a colour to do some kind of effects. I leave a portion of my background image transparent, so when I set the colour of the render Clear, I should see the colour I set.

But, it's not working :(

Every frame, I do this:

Code: [Select]

myWindow.Clear(sf::Color::Green);

I see the green when I open the window first of all and clear it, but after this, it's just black! I have check my graphics and they are all OK. I am using 32 bit PNGs.

Any ideas??

Do you flip the buffer ? 'myWindow.Display();' ?

With pleasure :)

Code: [Select]


myWindow.Clear(sf::Color::Green);
myWindow.Draw(mySprite);
// Now actually show it
myWindow.Display();


As I said, I just get a black background no matter what :(

Laurent was looking for a minimal program that reproduces the problem.

IE:  give us something that we can compile and run and see the problem for ourselves.

What you posted isn't enough, as that problem might be elsewhere in your program.

Sorry guys - it was my mistake all along (so what's new). I actually had 2 windows and I was clearing the wrong one! What a dunce.

Thanks anyway.
