[英]why wont my player move in python
我的播放器不會移動,我也不知道為什么。 我遵循了有關如何使其移動的教程。 我做了那個人所做的事情,但對我來說並沒有動。
這是我的代碼:
import pygame
pygame.init()
screen = pygame.display.set_mode((800,600))
pygame.display.set_caption("use arows")
class player:
def __init__(self ,x, y):
self.x = x
self.y = y
self.width = 32
self.height = 32
self.velocity = 0
self.falling = False
self.onGround = False
def detectCollisions(self,x1,y1,w1,h1,x2,y2,w2,h2):
if (x2+w2>=x1>=x2 and y2+h2>=y1>=y2):
return True
elif (x2+w2>=x1+w1>=x2 and y2+h2>=y1>=y2):
return True
elif (x2+w2>=x1>=x2 and y2+h2>=y1+h1>=y2):
return True
elif (x2+w2>=x1+w1>=x2 and y2+h2>=y1+h1>=y2):
return True
else:
return False
def update(self, gravity, blockList):
if (self.velocity < 0):
self.falling = True
collision = False
blockX,blockY = 0,0
for block in blockList:
collision = self.detectCollisions(self.x, self.y, self.width, self.height, block.x, block.y, block.width, block.height )
if collision == True:
blockx = block.x
blocky = block.y
break
if(collision == True):
if (self.falling == True):
self.falling == False
self.onGround== True
self.velocity = 0
self.y = blocky - self.height
if (self.onGround == False):
self.velocity += gravity
self.y -= self.velocity
def render(self,screen):
pygame.draw.rect(screen,(0,0,0),(self.x, self.y, self.width, self.height))
class Block:
def __init__ (self, x, y):
self.x = x
self.y = y
self.width = 32
self.height = 32
def render(self,screen):
pygame.draw.rect(screen,(0,0,0),(self.x, self.y, self.width, self.height))
gravity = -0.5
black = (0,0,0)
white = (255,255,255)
blue = (50,60,200)
clock = pygame.time.Clock()
player = player(0,0)
# 25 colums and 19 rows
level1 = [
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],

[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],
[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]
]
blockList = []
for y in range (0,len(level1)):
for x in range (0,len(level1[y])):
if (level1[y][x] == 1):
blockList.append(Block(x*32, y*32))
movex,movey=0,0
gameloop = True
while gameloop:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gameloop = False
if(event.type == pygame.KEYDOWN):
if (event.key == pygame.K_RIGHT):
movex = 5
elif (event.key == pygame.K_LEFT):
movex = -5
if(event.type == pygame.KEYUP):
if (event.key == pygame.K_RIGHT):
movex = 0
elif (event.key == pygame.K_LEFT):
movex = 0
screen.fill(blue)
for block in blockList:
block.render(screen)
player.update(gravity, blockList)
player.render(screen)
clock.tick(60)
pygame.display.update()
pygame.quit()
您的游戲循環中存在嵌套問題。 對事件操作的檢查需要在for循環內,因此它將檢查框架中的每個事件。 它僅檢查當前已編碼的最后一個事件。
縮進事件檢查,如下所示:
gameloop = True
while gameloop:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gameloop = False
if(event.type == pygame.KEYDOWN):
if (event.key == pygame.K_RIGHT):
movex = 5
elif (event.key == pygame.K_LEFT):
movex = -5
if(event.type == pygame.KEYUP):
if (event.key == pygame.K_RIGHT):
movex = 0
elif (event.key == pygame.K_LEFT):
movex = 0
編輯:
除上述內容外,未使用movex
變量,並且實際上,您的播放器更新功能中沒有水平移動的手段。
您需要對Player類進行一些更新:
def __init__(self ,x, y):
self.x = x
self.y = y
self.width = 32
self.height = 32
self.yVelocity = 0
self.xVelocity = 0 #Add xVelocity variable to track horizontal speed.
self.falling = False
self.onGround = False
def update(self, gravity, blockList):
if (self.yVelocity < 0):
self.falling = True
collision = False
blockX,blockY = 0,0
for block in blockList:
collision = self.detectCollisions(self.x, self.y, self.width, self.height, block.x, block.y, block.width, block.height )
if collision == True:
blockx = block.x
blocky = block.y
break
if(collision == True):
if (self.falling == True):
self.falling == False
self.onGround== True
self.yVelocity = 0
self.xVelocity = 0 #On a collision, stop all movement.
self.y = blocky - self.height
if (self.onGround == False):
self.yVelocity += gravity
self.y -= self.yVelocity
self.x -= self.xVelocity #Modify position according to velocity.
然后,在游戲循環中,根據輸入更新玩家的xVelocity:
player.xVelocity = movex #Update horizontal velocity.
player.update(gravity, blockList)
player.render(screen)
clock.tick(60)
那應該有幫助。
