我正在使用python和pygame进行平台游戏.整个代码可以在“https://github.com/C-Kimber/FBLA_Game”找到.我遇到的问题是玩家精灵和墙壁精灵之间的碰撞,特别是角落.当玩家按下x移动键并且他们跳跃时,玩家要么不移动,要么被卡住.这是碰撞样本：

def wallCollisions(self):

    block_hit_list = pygame.sprite.spritecollide(self, self.walls, False)

    for block in block_hit_list:


        if self.rect.bottom >= block.rect.top and self.rect.bottom <= block.rect.top + 15:  # Moving down; Hit the top side of the wall
            if self.rect.right > block.rect.left:
                self.rect.bottom = block.rect.top
                self.yvel = 0
                self.onGround = True
                self.jumps = 1
        elif self.rect.top <= block.rect.bottom and self.rect.top >= block.rect.bottom - 15:  # Moving up; Hit the bottom side of the wall
            self.rect.top = block.rect.bottom
            self.yvel = 0
        if self.rect.right >= block.rect.left and self.rect.right <= block.rect.left + 15:  # Moving right; Hit the left side of the wall
            if self.rect.bottom > block.rect.top+15:
                self.rect.right = block.rect.left#+1
                self.xvel = 0
        elif self.rect.left <= block.rect.right and self.rect.left >= block.rect.right - 15:  # Moving left; Hit the right side of the wall
            self.rect.left = block.rect.right#-1
            self.xvel = 0 = block.rect.right#-1
            self.xvel = 0

我已经将图像包含在正在发生的事情和我想要的内容中.

我尝试过其他方法,例如使用速度作为确定碰撞的因素,但这是目前为止最好的方法.如果您能提供解决方案,我们将不胜感激.

解决方法:

谢谢用户树懒！他联系的问题给了我一些非常需要的清晰度.它花了我一点但我实现了它.我为碰撞创建了一个函数.

def wallColl(self, xvel, yvel, colliders):
    for collider in colliders:
        if pygame.sprite.collide_rect(self, collider):
            if xvel > 0:
                self.rect.right = collider.rect.left
                self.xvel = 0
            if xvel < 0:
                self.rect.left = collider.rect.right
                self.xvel = 0
            if yvel < 0:
                self.rect.bottom = collider.rect.top
                self.onGround = True
                self.jumps = 3
                self.yvel = 0
            if yvel > 0:
                self.yvel = 0
                self.rect.top = collider.rect.bottom

然后我在我的更新功能中调用它们.

def update(self):
    self.rect.x += self.xvel
    # self.walls is an array of sprites.
    self.wallColl(self.xvel, 0, self.walls) 

    self.rect.y -= self.yvel
    self.onGround = False
    self.wallColl(0, self.yvel, self.walls)

    self.wallCollisions()
    if self.otherplayers != None:
        self.playerCollisions()

    # Gravity
    if self.onGround == False:
        self.yvel-=.0066*self.mass

    self.boundries(highbound, lowbound, leftbound, rightbound)
    self.down = False

我游戏中的实际使用使得可用性接近完美.不过100％,这不是一个完美的答案.
