Scratch

No what I plan to do is have a sprite which reads the colours on the line , replaces them with white and stamping a copy one space below. Right now I need help simply turning the full line white.

Yeah.
Making the whole thing white is easy.

But you will probably need a block for every grid piece or something because otherwise the blocks will not come down and it will not work properly.

Thanks! I'll try that.

This will result in a domino affect as the falling will propagate one block at a time until it reaches the highest block from each column. Even if you use a separate sprite to handled each column and run in turbo mode this will be painfully slow. The idea of animating the falling motion becomes ludicrous.

As I said before, one sprite for each grid cell is the best. There are some tricky scripting techniques that let you make one sprite and then just copy it as many times as as you need. The sprites will figure out where to go and what to do on there own. It is far to complex to explain here so I would have to code it for you. But I'm a busy man with a job and a wife and daughter.

I did some testing and I was wrong. Your idea will work just fine without resorting to turbo mode. Here is the test I did. Let me know when you have a copy so I can remove the project. Just customize it a bit then make a copy for each column. Change the x: coordinate for each copy. Make sure you don't use any color found in your background because the flash player will detect it even after it has been stamped over.
