Pygame - AttributeError: 'int' object has no attribute 'y' - python-2.7

Question

Hello I am currently working on a game in pygame and I am now trying to add a ground, gravity and jump. When I run the code I get an attribute error. Please help if you have a fix, here is the code:
import pygame, sys, time
from pygame.locals import *
pygame.init()
# A few variables
zx = 320
zy = 320
x = 25
y = 320
velX = 0
velY = 0
gravity = .50
ground = 720
clock = pygame.time.Clock()
# Screen
size = 1280, 720
screen = pygame.display.set_mode(size)
pygame.display.set_caption('Moon Survival!')
# Moon
moon = pygame.image.load('images/arena2.jpg')
pygame.display.update()
# Player
class Player(pygame.sprite.Sprite):
global gravity
def __init__(self, x, y):
# Player dimensions and position
self.x = x
self.y = y
self.width = 80
self.height = 80
# Player image and animation
self.i0 = pygame.image.load('images/soldier.png')
self.i1 = pygame.image.load('images/soldier2.png')
self.timeTarget = 10
self.timeNum = 0
self.currentImage = 0
# Jump and gravity
self.vSpeed = 1
self.jumpForce = 8
self.maxVspeed = 3
self.isJumping = False
# Jump inputs
def getInput(self):
keys = pygame.key.get_pressed()
if keys[pygame.K_SPACE]:
if not self.isJumping:
self.isJumping = True
# PLayer updates
def update(self):
# Jumping
self.getInput()
self.vSpeed += gravity
if self.vSpeed > self.maxVspeed:
self.vSpeed = self.maxVspeed
self.y += self.vSpeed
if self.y >= ground.y:
self.vSpeed = 0
self.y = ground.y
self.isJumping = False
if self.isJumping:
self.vSpeed += -self.jumpForce
# Animations
#self.timeNum += 1
if (self.timeNum == self.timeTarget):
if (self.currentImage == 0):
self.currentImage = 0
else:
self.currentImage = 0
self.timeNum = 0
self.render()
# Player rendering
def render(self):
if (self.currentImage == 0):
screen.blit(self.i0, (self.x, self.y))
#else:
#screen.blit(self.i1, (self.x, self.y))
# Zombies
zombie = pygame.image.load('images/zombie.png')
pygame.display.update()
# Sprite variables
player = Player(25, 320)
# Game loop
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# Movement
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
velX = -5
if event.key == pygame.K_d:
velX = +5
if event.type == pygame.KEYUP:
if event.key == pygame.K_a:
velX = 0
if event.key == pygame.K_d:
velX = 0
# Image blitting
screen.blit(moon, (0,0))
screen.blit(zombie, (zx, zy))
# Movement variables
player.x += velX
player.y += velY
player.update()
# Screen wrap
if player.x >= 1240:
player.x = 1
if player.x <= 0:
player.x = 1240
# Display updating
clock.tick(75)
pygame.display.update()
Any help will be greatly appreciated, thank you.

Answer 1

In some places you try to use int value as object:
ground = 720
self.y = ground.y # error !!!
ground is number int(integer) not object with .y
You could use pygame.Rect()
ground = pygame.Rect(0, 750, 0, 0) # (x, y, width, heigh)
and then you can use ground.x, ground.y, and others - see pygame.Rect().
.
btw: you should move #Movement code, # Movement variablescode, # Screen wrap code into Player class as functions and call that functions in main loop - to make main loop more readable.
# Movement variablescode, # Screen wrap code could be in player.update
# Movement code could be in Player class as event_handler(self, event)
def event_handler(self, event):
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_a:
velX = -5
elif event.key == pygame.K_d:
velX = +5
elif event.type == pygame.KEYUP:
if event.key in (pygame.K_a, pygame.K_d):
velX = 0
(you can use elif as above)
Now you can use this in main loop player.event_handler(event)
EDIT:
I made many modifications in your code - but I had no time to finish it.
Player still doesn't jump. But you have 10 moving zombies, pause (press P) and all in classes.
