我的平台图像冲突问题如何解决? [英] My Collision With My Platform Images Problem How To Fix?

问题描述

问题是，当我与我的平台发生碰撞时，它似乎让我比平台更高对我所有的平台都这样做，我知道为什么

the problem is that when I collide with my platform it seems to put me way higher then the platform it does this for all my platforms and idk why

我的平台碰撞

        for enemy in enemies:
            if playerman.rect.colliderect(enemy.rect):
                collide = True
                playerman.y = enemy.rect.top - playerman.height + 1
                if playerman.rect.right > enemy.rect.left and playerman.rect.left < enemy.rect.left - playerman.width:
                    playerman.x = enemy.rect.left - player.width
                if playerman.rect.left < enemy.rect.right and playerman.rect.right > enemy.rect.right + playerman.width:
                    playerman.x = enemy.rect.right

推荐答案

问题隐藏在 Platform 类中，因为 self.platforms 和 不一样代码>平台.
注意 self.platforms 被缩放到它的一半大小，因此你在设置矩形时必须使用 self.platforms 而不是 platform (<代码>self.rect):

The issue is hidden in the class Platform, because self.platforms is not the same as platform.
Note self.platforms is scaled to its half size, thus you have to use self.platforms rather than platform when you setup the rectangle (self.rect):

self.rect = pygame.Rect(x,y,platforms.get_width(),platforms.get_height())

self.rect = pygame.Rect(x,y, self.platforms.get_width(), self.platforms.get_height())

无论如何，我建议通过 get_rect() 获取矩形:

Anyway, I recommend to get the rectangle by get_rect():

self.rect = self.platforms.get_rect(topleft = (x, y))

class Paltform:

class enemy:
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height
        self.width = width
        self.color = color
        self.rect = pygame.Rect(x,y,height,width)
        self.platforms = pygame.image.load("rat.png")
        self.platforms = pygame.transform.scale(self.platforms,(self.platforms.get_width()//2,self.platforms.get_height()//2))

        self.rect = self.platforms.get_rect(topleft = (x, y)) # <---

        self.direction = "left" #set a stating direction

如果图像的顶部不是可击中，例如散布草，则您必须将击中框缩小草的高度.
向 enemy 类添加一个方法，该方法返回命中框:

If the top of the image is not hittable, like spread grass, the you have to shrink the hitbox by the height of the grass.
Add a method to the class enemy, which returns the hitbox:

class enemy:
    # [...]

    def get_hitbox(self):
        grass_height = 25
        hitboxb = self.rect
        hitboxb.top += grass_height
        return hitboxb

class botts:
    # [...]

    def get_hitbox(self):
        return self.rect

使用碰撞框进行碰撞检测:

Use the hit box for the collision detection:

for enemy in enemies:

     enemy_hitbox = enemy.get_hitbox()

     if playerman.rect.colliderect(enemy_hitbox):
         collide = True
         playerman.y = enemy_hitbox.top - playerman.height + 1
         # [...]
