Not able to make a specific thing pause in pygame - cooImanreebro - Dec-13-2020
when i use time.sleep() or pygame.time.wait() it always freezes the whole game instead of one specific thing.
lets say i want to make a door open and close every few seconds. when i do that instead of just pausing the door it pauses the whole game every few seconds:
elif self.flag == 'door_v':
self.x -= 3
if abs(self.x - self.door_prev_pos) > TILE:
self.door_open_trigger = False
pygame.time.wait(2000)
self.door_close_trigger = True

Yes these two commands will freeze the whole thing. What you can do is to set a variable to record how long the time has passed and freeze only the part you want to freeze, something like the following. I have developed a game using this method, you can check out..
t0 = time.time() if time.time() - t0 > timestep: freeze the part t0 = time.time()

Those functions pause the whole script. Do you have a game loop? What you need are timed updates for your doors, where they measure how much time has passed and open and close how you want.
class Door():
def __init__(self):
self.last_update = pygame.time.get_ticks()
self.interval = 1000 # 1 second
self.state = "closed"
def update(self):
now = pygame.time.get_ticks()
if now - self.last_update > self.interval:
self.last_update = now
if self.state == "closed":
self.state = "open"
else:
self.state = "closed"

How about setting a flag that tells the door handler code that it should open/close the door, leave it closed or leave it open? It is very rare that you use anything other than really short delays in a game (or any interactive program for that matter).
Hopefully this code conveys what I am trying to say.
from tkinter import *
root = Tk()
door_command = 'TOGGLE'
door = StringVar()
def update_door():
state = door.get()
if state != door_command:
if door_command == 'TOGGLE':
door.set('OPEN' if state == 'CLOSE' else 'CLOSE')
else:
door.set(door_command)
root.after(1000, update_door)
def set_door(command):
global door_command
door_command = command
Label(root, textvariable=door, width=10).pack()
Button(root, text='Open Door', command=lambda:set_door('OPEN')).pack()
Button(root, text='Close Door', command=lambda:set_door('CLOSE')).pack()
Button(root, text='Toggle', command=lambda:set_door('TOGGLE')).pack()
update_door()
mainloop()I have two functions, set_door() and update_door(). set_door() tells the program what it is supposed to do; close the door (CLOSE), open the door (OPEN), or open and close the door over and over (TOGGLE).update_door() actually controls the door. Here it just updates a label, but it could just as easily control a sprite. This function is called every second but only does something when the door state is different than the door command. And if the door command is 'TOGGLE' it opens or closes the door based on the current state.

sorry i need to put it more clear:
def door_open(self):
if self.flag == 'door_h':
self.y -= 3
if abs(self.y - self.door_prev_pos) > TILE:
self.door_open_trigger = False
self.door_close_trigger = True
elif self.flag == 'door_v':
self.x -= 3
if abs(self.x - self.door_prev_pos) > TILE:
self.door_open_trigger = False
now = pygame.time.get_ticks()
if now - self.last_update > self.interval:
self.last_update = now
self.door_close_trigger = True
def door_close(self):
if self.flag == 'door_v':
for i in range(self.amount):
self.times += 0.2
waited = self.wait
if self.count < self.speed:
self.count += 1
else:
self.x += 3
self.count = 0
if self.times < self.amount + 6:
return waited
if self.flag == 'door_h':
for i in range(self.amount):
self.times += 0.2
waited = self.wait
if self.count < self.speed:
self.count += 1
else:
self.y += 3
self.count = 0
if self.times < self.amount + 6:
return waited
this is the whole code. i wanted to make it so when i open the door it automatically closes after 1 or 2 seconds.
