在图书馆Pygame中，我正在尝试编写游戏。在游戏中，如果您与目标矩形发生碰撞，则会进入新的水平。一切正常但是当你与目标矩形发生碰撞时，它会在旧级别的顶层上绘制新级别。我希望它清除屏幕，然后绘制水平。我该怎么做？这是我的代码：
import os, random, pygame, eztext
from time import *
speed = 1
gravityNum = 1
gravity = True
keyDown = True
rightNum = 0
running = True
pygame.init()
white = (255, 255, 255)
screen = pygame.display.set_mode((880, 400))
class Player(object):
def __init__(self):
self.rect = pygame.Rect(16, 368, 16, 16)
self.level = 1
def move(self, dx, dy):
if dx != 0:
self.move2(dx, 0)
if dy != 0:
self.move2(0, dy)
def move2(self, dx, dy):
self.rect.x += dx
self.rect.y += dy
for wall in walls:
if self.rect.colliderect(wall.rect):
if dx > 0:
self.rect.right = wall.rect.left
if dx < 0:
self.rect.left = wall.rect.right
if dy > 0:
self.rect.bottom = wall.rect.top
if dy < 0:
self.rect.top = wall.rect.bottom
for enemy in enemies:
if self.rect.colliderect(enemy.rect):
player.move(-(self.rect.x - 16), -(self.rect.y - 368))
for goal in goals:
if self.rect.colliderect(goal.rect):
player.move(-(self.rect.x - 16), -(self.rect.y - 368))
self.level += 1
self.levelCheck()

答案 0 :(得分：0)
当你击败关卡时，重置你的墙壁，敌人和目标列表。 换句话说，在将所有新级别数据附加到它们之前使它们= []
