Flashing Invert

[NicK]

I had an idea to create a graphics effect that it rapid color inverting of the screen from white to black to white a few times. Any ideas how this could be implemented? Is there an easy was to grab the screen buffer and modify it etc?

The latest beta version of the library has INVERT as one of the colors, I'm not 100% certain but I don't think it's made it into the main branch yet?

Alternatively, if you prefer to twiddle the back-buffer manually you can get a pointer to it by calling gb.display.getBuffer().

Myndale is right, the new INVERT color is still only in the beta branch.
One fast and easy way would be to use gb.display.fillScreen() in my opinion. This function uses memset so it's almost instant compared to gb.display.fillRect.

thanks. The kind of effect I'm trying to get is to invert the entire screen at that instant - including all background and bitmaps/sprites - and then cycle this a few times. This would just be an effect if you die in a game for example.
