我学习了一些使用方块的Pygame的基础知识如何开始使用图像？

Question

我的问题是在我的球员身上，我说了一个方向陈述，如果我向右走，然后向右飞，如果我向左飞，然后向左飞，但是 当我没有点击任何我的玩家没有站着的东西时，它会一直向左或向右点击，我不知道为什么这里有一个video

Answer 1

将每个对象更改为图像很容易，您可以使用pygame.image.load(filename)加载图像，然后将其显示在屏幕上

在player类中，加载图像并更改

class player:
    def __init__(self,x,y,height,width,color):
        self.left_image = pygame.image.load("whatever_the_image_is_called.png")
        self.right_image = pygame.image.load("whatever_the_image_is_called.png")
        ...
        self.rect = pygame.Rect(x,y,left_image.get_width(), left_image.get_height())
        self.direction = "left" #set a stating direction

然后，要将它们放到屏幕上，请单击它们

def draw(self):
    self.rect.topleft = (self.x,self.y)
    if self.direction == "left":
        screen.blit(self.left_image,self.rect)
    else:
        screen.blit(self.right_image,self.rect)

然后当你改变方向时

if keys[pygame.K_LEFT]:
    playerman.direction = "left"

if keys[pygame.K_RIGHT]:
    playerman.direction = "right"

对于其他类，您不需要self.direction，它们只有一个方向，所以只需blit一个图像

如您所见，我使用了图像宽度和高度，而不是作为self.rect的参数传递的w和h，因此您可以去掉这些，您还必须确保图像的大小正确

您可以使用pygame.transform.scale(image,size)将图像大小调整到正确的大小

例如self.left_image = pygame.transform.scale(self.left_image,(100,100))。这会将图像更改为100x100，但可能会因此而失真

self.left_image = pygame.transform.scale(self.left_image,(self.left_image.get_width()//2,self.left_image.get_height()//2))

这会将图像缩放到一半大小，保持纵横比

对于动画，我发现最好使用一个列表，然后获得每个精灵，幸运的是，您已经很好地命名了它们，您可以这样做

self.left_anim = []
for i in range(2,10,1):
    self.left_anim.append(pygame.image.load("Sprite" + str(i).zfill(4)))

str(i).zfill(4)使其前面有3个零

然后通过动画有一个计数器

self.anim_index = 0

def draw(self):
    screen.blit(self.left_anim[self.anim_index]) #put the current frame on screen
    self.anim_index += 1 #go to next frame
    if self.anim_index == len(self.left_anim): #if reached end of animation
        self.anim_index = 0 #reset

---

for i in range(2,10,1):
    self.painful.append[pygame.image.load("dots1.png"),[pygame.image.load("dots2.png"),[pygame.image.load("dots3.png"),[pygame.image.load("dots4.png"),[pygame.image.load("dots5.png")

循环是这样的，你不需要为每个图像都有一个pygame.image.load()，你只需要一个

for i in range(1,5,1):
    self.painful.append(pygame.image.load("dots%d.png" %(str(1)))

或者只是没有循环

self.painful = [
    pygame.image.load("dots1.png"),
    pygame.image.load("dots2.png"),
    pygame.image.load("dots3.png"),
    pygame.image.load("dots4.png"),
    pygame.image.load("dots5.png")
]

然后确保self.rect.topleft =位于if语句之外，因为您希望它在每一帧发生，而不仅仅是在动画结束时发生

def draw(self):
    screen.blit(self.painful[self.anim_index],self.rect)) #put the current frame on screen
    self.anim_index += 1 #go to next frame
    if self.anim_index == len(self.painful): #if reached end of animation
        self.anim_index = 0 #reset
    self.rect.topleft = (self.x,self.y) #***** this part here ******
    pygame.draw.rect(window,self.color,self.rect)
