There are a lot of bugs cause I move the blocks one by one. And I added colors but they mix with the original color

@cvp I did also moving blocks down, in cycle for, one by one each block. Is there a way think of a figure as a single block?

@cvp I thought to write how to move blocks right and left in the touch_began of arrows. But no matter, you did it easier👍

@cvp So the Tetris didn’t receive touches?
I thought to put the moving ➡️⬅️ into arrows, but it would be much more confusing

And if with arrows? Maybe it looks on that touch_began

Maybe you’ll check if it works?

@cvp it’s in the game class that inherited scene. And update in the class he sees

@cvp did so that the block moves down, but for ⬅️➡️ my touch_began doesn’t work. I did this

def touch_began(self, touch):
        print('touch_began') 

And nothing in the console

@cvp so the center is (0, 0)?
