问题
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
my collision for platform
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

回答1:
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())
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
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
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
# [...]
