我想制作一个俄罗斯方块游戏,但我不明白这个错误? 这似乎是第34行:Python TypeError:错误的操作数类型为一元 - '元组'
self.active_blk.move(-direction)
这里是我的代码:
import pygame
import random
from Block import Block
class Stage():
def __init__(self,cell_size,h_cells,v_cells):
self.cell_size=cell_size
self.width=h_cells
self.height=v_cells
self.blocks=[]
self.active_blk=self.add_block()
def add_block(self):
blk=Block(0,self.cell_size,(random.randint(0,255),random.randint(0,255),random.randint(0,255)))
self.blocks.append(blk)
return blk
def move_block(self,direction):
self.active_blk.move(direction)
obstacle=False
for cell in self.active_blk.cells:
if(cell.y>=self.height or
cell.x<0 or
cell.x>= self.width): obstacle=True
for blk in self.blocks:
if(blk is self.active_blk): continue
if(blk.collide_with(self.active_blk)):
obstacle=True
break;
if(obstacle):
self.active_blk.move(-direction)
def draw(self,screen):
screen.fill((0,0,0))
for blk in self.blocks:
blk.draw(screen)
'move_block'在哪里被调用? – Ryan
“方向”显然是一个元组。而且你不能这样做' - (x,y)' –
'stage.move_block((0,1))' – Coder22
