So I have read the Threads Guide, but got stucked on this point:
class Program:
def __init__(self):
self.width = 1000
self.height = 800
self.panel_width = 200
#self.root = Tk()
self.canvas = tkinter.Canvas(width=self.width, height=self.height, bg="black")
self.canvas.pack()
self.canvas.bind("<ButtonPress>", self.click)
self.figures_images = {"0": tkinter.PhotoImage(file="white_pawn.png"), ...}
self.figures = {"0":[<class Pawn...>, (x,y), image_id],"1":[<class Pawn...>, (x,y), image_id],"2":[<class Pawn...>, (x,y), image_id],...}
...
def create_layout(self):
# not important for this problem
def start_ai(self):
...
move = Move_ai(self)
# next methods are not important now
class Pawn:
def __init__(self, ...):
...
# not important for this problem
class Move_ai:
def __init__(self, program):
self.main = program
thread = threading.Thread(target=self.move)
thread.start()
def move(self):
time.sleep(3) # just to pretend PC is thinking
... # some code calculating which figure to move
selected_id = ... # id of figure it decided to move with
self.main.canvas.coords(self.main.figures_images[selected_id], tuple_of_coords)
# ^ and this is that line raising an error to me, this one:Error:Exception in thread Thread-1:
