Question

I'm having trouble with the tetrominoes.
I have created all of the shapes and i can draw all of them separatelly, but when i try to draw 2 or more, i get the following error:
GraphicsError: Object currently drawn
i've tried with the for loop given in the example and also i've tried this:

new_win=GraphWin('Tetrominoes',900,150)
tetrominoes=[I_Shape,J_Shape,L_Shape,O_Shape,S_Shape,T_Shape,Z_Shape]
x=3
shape=I_Shape(Point(x,1))
shape2=J_Shape(Point(x+4,4))
shape2.draw(new_win)
shape.draw(new_win)
new_win.mainloop()

and i keep getting the same error.
Help please

Answer 1

i've made it work, i can't use the same window twice, so, first have to define all the shapes and then draw them in the window.
The code in the example doesn't work:

for tetromino in tetrominoes:
shape = tetromino(Point(x, 1))
shape.draw(win)
x += 4

i made it work with the following changes:

for tetromino in tetrominoes:
shape=tetromino(Point(x,1))
print tetromino
x+=4

shape.draw(new_win)
