[英]How do I move elements of a matrix in python?
我想用鍵盤移動 object 1,使用來自 pygame 的事件,例如:pygame.key.get_pressed()。 但我不知道如何將它放在我的代碼中。
import pygame
pygame.init()
tela = pygame.display.set_mode((1000, 560))
jogo = True
class Tabuleiro:
def __init__(self, tela, x, y):
self.x = x
self.y = y
self.tela = tela
self.maze = [[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1],
[1, 0, 1, 1, 0, 1, 3, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1],
[1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 3, 1],
[1, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 1, 0, 1, 1, 0, 1, 0, 1],
[1, 0, 2, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1],
[1, 0, 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 0, 1],
[1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1],
[1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1],
[1, 0, 0, 0, 3, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]]
def show(self):
for col in range(20):
for lin in range(11):
if self.maze[lin][col] == 1:
self.tela.fill((255, 255, 255), rect=[self.x + col * 49, self.y + lin * 49, 49, 49])
if self.maze[lin][col] == 2:
self.tela.fill((255, 255, 0), rect=[self.x + col * 30, self.y + lin * 30, 25, 25])
if self.maze[lin][col] == 3:
self.tela.fill((255, 0, 0), rect=[self.x + col * 50, self.y + lin * 50, 25, 25])
maze = tabuleiro.Tabuleiro(tela, 10, 10)
while jogo:
for event in pygame.event.get():
if event.type == pygame.QUIT:
jogo = False
tela.fill(0)
maze.show()
pygame.display.update()
而且我也不知道如何使用碰撞函數,此代碼適用於我必須作為學校作業完成的吃豆人游戲。 如果我也能得到一些關於它的提示,我很高興。 謝謝你。
首先,您需要修復迷宮的表示。 每個單元格的左上角是self.x + col * 50, self.y + lin * 50
:
class Tabuleiro:
# [...]
def show(self):
for col in range(20):
for lin in range(11):
if self.maze[lin][col] == 1:
self.tela.fill((255, 255, 255), rect=[self.x + col * 50, self.y + lin * 50, 50, 50])
if self.maze[lin][col] == 2:
self.tela.fill((255, 255, 0), rect=[self.x + col * 50 + 12, self.y + lin * 50 + 12, 25, 25])
if self.maze[lin][col] == 3:
self.tela.fill((255, 0, 0), rect=[self.x + col * 50 + 12, self.y + lin * 50 + 12, 25, 25])
你需要在Tabuleiro
class中添加一些方法,添加一個可以在網格中查找特定number
的方法:
class Tabuleiro:
# [...]
def findFirst(self, number):
for row, rowlist in enumerate(self.maze):
for col, cell in enumerate(rowlist):
if cell == number:
return row, col
return None, None
添加一個方法來測試行索引 ( row
) 和列索引 ( col
) 是否有效:
class Tabuleiro:
# [...]
def testIndex(self, row, col):
if row == None or col == None:
return False
if 0 <= row < len(self.maze) and 0 <= col < len(self.maze[row]):
return True
return False
添加一個方法來測試單元格的內容是否為特定number
:
class Tabuleiro:
# [...]
def isFieldEqual(self, row, col, number):
if self.testIndex(row, col):
return self.maze[row][col] == number
return False
添加一個交換 2 個單元格內容的方法:
class Tabuleiro:
# [...]
def swapFileds(self, row1, col1, row2, col2):
if self.testIndex(row1, col1) and self.testIndex(row2, col2):
self.maze[row1][col1], self.maze[row2][col2] = self.maze[row2][col2], self.maze[row1][col1]
Pygame中有幾種檢測按鍵按下的方法,參見How to get if a key is pressed pygame 。
例如,使用`KEYDOWN 事件。 每當您要移動一個 object 時,您需要測試要移動到的單元格是否為空 (0)。 移動時,僅交換單元格的內容:
while jogo:
row, col = maze.findFirst(2)
for event in pygame.event.get():
if event.type == pygame.QUIT:
jogo = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
if maze.isFieldEqual(row, col-1, 0):
maze.swapFileds(row, col-1, row, col)
if event.key == pygame.K_RIGHT:
if maze.isFieldEqual(row, col+1, 0):
maze.swapFileds(row, col+1, row, col)
if event.key == pygame.K_UP:
if maze.isFieldEqual(row-1, col, 0):
maze.swapFileds(row, col, row-1, col)
if event.key == pygame.K_DOWN:
if maze.isFieldEqual(row+1, col, 0):
maze.swapFileds(row+1, col, row, col)
最小的例子:
import pygame
pygame.init()
tela = pygame.display.set_mode((1000, 560))
jogo = True
class Tabuleiro:
def __init__(self, tela, x, y):
self.x = x
self.y = y
self.tela = tela
self.maze = [[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
[1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1],
[1, 0, 1, 1, 0, 1, 3, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1],
[1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 3, 1],
[1, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 1, 0, 1, 1, 0, 1, 0, 1],
[1, 0, 2, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1],
[1, 0, 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 0, 1],
[1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1],
[1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1],
[1, 0, 0, 0, 3, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1],
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]]
