Yes, this question has been asked before. No, none of the answers I read could fix the problem I have.
I'm trying to create a little Bounce game. I've created the bricks like this:
def __init__(self,canvas):
self.canvas = canvas
self.brick1 = canvas.create_rectangle(0,0,50,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick2 = canvas.create_rectangle(50,0,100,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick3 = canvas.create_rectangle(100,0,150,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick4 = canvas.create_rectangle(150,0,200,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick5 = canvas.create_rectangle(200,0,250,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick6 = canvas.create_rectangle(250,0,300,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick7 = canvas.create_rectangle(300,0,350,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick8 = canvas.create_rectangle(350,0,400,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick9 = canvas.create_rectangle(400,0,450,20,fill=random_fill_colour(),outline=random_fill_colour())
self.brick10 = canvas.create_rectangle(450,0,500,20,fill=random_fill_colour(),outline=random_fill_colour())
self.bricksId = [self.brick1,self.brick2,self.brick3,self.brick4,self.brick5,self.brick6,self.brick7,self.brick8,self.brick9,self.brick10]
And I'm trying to reference the ID of bricksId[0]
over here:
self.hit_brick(pos,self.bricks.bricksId[0])
Earlier, in the __init__
, I define bricks as bricks, which is defined as Brick(canvas)
. However, the error states:
TypeError: 'Brick' object does not support indexing
In the answers to the other questions of this subject, I cannot find any that help me access bricks.bricksId[0]
.
In order for the Brick
object to be indexable, you must implement the methods:
__getitem__
__setitem__
__delitem__
You don't need all of them, only the ones you use.
However, this seems like a case of self.bricks
being a brick instead of a list of bricks. A list of bricks is indexable; however, a brick itself is not unless you implement the methods above.
Check this for reference.
In order to be able to call self.bricks.bricksId[number]
when I needed:
def __getitem__(self,index):
return self.bricks.bricksId[index]
def __setitem__(self,index,value):
self.bricks.bricksId[index] = value
