The StickFigureSprite type will understand how to load its personal photos. the following few strains of the __init__ functionality do that very activity: They load all of the 3 left photographs (which we’ll use to animate the stick determine operating left) and the 3 correct photos (used to animate the stick determine operating right). we have to load those pictures now, simply because we don’t are looking to need to load them at any time when we exhibit the stick determine at the monitor (doing so could take too lengthy and make our online game run slowly). classification StickFigureSprite(Sprite): def __init__(self, game): Sprite. __init__(self, video game) self. images_left = [ PhotoImage(file="figure-L1. gif"), PhotoImage(file="figure-L2. gif"), PhotoImage(file="figure-L3. gif") ] self. images_right = [ PhotoImage(file="figure-R1. gif"), PhotoImage(file="figure-R2. gif"), PhotoImage(file="figure-R3. gif") ] self. photo = video game. canvas. create_image(200, 470, \ image=self. images_left, anchor='nw') This code so much all of the 3 left photos, which we’ll use to animate the stick determine operating left, and the 3 correct photos, which we’ll use to animate the stick determine working correct. At and , we create the article variables images_left and images_right. every one incorporates a checklist of PhotoImage items that we created in bankruptcy 15, exhibiting the stick determine dealing with left and correct. We draw the 1st photograph at with images_left utilizing the canvas’s create_image functionality at place (200, 470), which places the stick determine in the midst of the sport monitor, on the backside of the canvas. The create_image functionality returns a host that identifies the picture at the canvas. We shop this identifier within the item variable picture for later use. establishing Variables the following a part of the __init__ functionality units up a few extra variables that we’ll be utilizing later during this code. self. images_right = [ PhotoImage(file="figure-R1. gif"), PhotoImage(file="figure-R2. gif"), PhotoImage(file="figure-R3. gif") ] self. photo = video game. canvas. create_image(200, 470, \ image=self. images_left, anchor='nw') self. x = −2 self. y = zero self. current_image = zero self. current_image_add = 1 self. jump_count = zero self. last_time = time. time() self. coordinates = Coords() At and , the article variables x and y will shop the volume we’ll be including to the stick figure’s horizontal (x1 and x2) or vertical (y1 and y2) coordinates whilst he's relocating round the reveal. As you discovered in bankruptcy thirteen, to be able to animate whatever with the tkinter module, we upload values to the object’s x or y place to maneuver it round the canvas. by means of surroundings x to −2, and y to zero, we subtract 2 from the x place later within the code and upload not anything to the vertical place, to make the stick determine run to the left. word do not forget that a destructive x quantity capability flow left at the canvas, and a favorable x quantity capability circulate correct. A damaging y quantity potential movement up, and a good y quantity ability stream down. At , we create the article variable current_image to shop the image’s index place as at the moment displayed at the display.
