Y = four self. online game. canvas. move(self. snapshot, self. x, self. y) At , we fee even if either the falling and backside variables are set to precise. if this is the case, we’ve looped via each platform sprite within the record with no colliding on the backside. the ultimate register this line determines even if the ground of our personality is lower than the canvas height—that is, above the floor (the backside of the canvas). If the stick determine hasn’t collided with whatever and he's above the floor, he's status in midair, so he may still commence falling (in different phrases, he has run off the tip of a platform). To make him run off the tip of any platform, we set y equivalent to four at . At , we movement the picture around the monitor, based on the values we set within the variables x and y. the truth that we’ve looped throughout the sprites checking for collisions might suggest that we’ve set either variables to zero, as the stick determine has collided at the left and with the ground. if that's the case, the decision to the movement functionality of the canvas will do not anything. it could actually even be the case that Mr. Stick guy has walked off the sting of a platform. If that occurs, y might be set to four, and Mr. Stick guy will fall downward. Phew, that used to be a protracted functionality! trying out Our Stick determine Sprite Having created the StickFigureSprite category, let’s check it out by means of including the subsequent strains prior to the decision to the mainloop functionality. sf = StickFigureSprite(g) g. sprites. append(sf) g. mainloop() At , we create a StickFigureSprite item and set it equivalent to the variable sf. As we did with the systems, we upload this new variable to the checklist of sprites saved within the online game item at . Now run this system. you will discover that Mr. Stick guy can run, bounce from platform to platform, and fall! The Door! the one factor lacking from our online game is the door to the go out. We’ll wind up via making a sprite for the door, including code to realize the door, and giving our software a door item. developing the DoorSprite category You guessed it—we have to create another type: DoorSprite. Here’s the beginning of the code: category DoorSprite(Sprite): def __init__(self, online game, photo_image, x, y, width, height): Sprite. __init__(self, online game) self. photo_image = photo_image self. photo = online game. canvas. create_image(x, y, \ image=self. photo_image, anchor='nw') self. coordinates = Coords(x, y, x + (width / 2), y + top) self. endgame = precise As proven at , the __init__ functionality of the DoorSprite type has parameters for self, a video game item, a photo_image item, the x and y coordinates, and the width and top of the picture. At , we name __init__ as with our different sprite periods. At , we retailer the parameter photo_image utilizing an item variable with a similar identify, as we did with PlatformSprite. We create a exhibit photo utilizing the canvas create_image functionality and shop the selecting quantity again via that functionality utilizing the article variable photograph at . At , we set the coordinates of DoorSprite to the x and y parameters (which develop into the x1 and y1 positions of the door), after which calculate the x2 and y2 positions.
