How can i calculate the mouse speed with Pygame? - python

import pygame
import datetime
with open('textdatei.txt', 'a') as file:
pygame.init()
print("Start: " + str(datetime.datetime.now()), file=file)
screen = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()
BG_COLOR = pygame.Color('gray12')
done = False
while not done:
# This event loop empties the event queue each frame.
for event in pygame.event.get():
# Quit by pressing the X button of the window.
if event.type == pygame.QUIT:
done = True
elif event.type == pygame.MOUSEBUTTONDOWN:
# MOUSEBUTTONDOWN events have a pos and a button attribute
# which you can use as well. This will be printed once per
# event / mouse click.
print('In the event loop:', event.pos, event.button)
print("Maus wurde geklickt: " + str(datetime.datetime.now()), file=file)
# Instead of the event loop above you could also call pygame.event.pump
# each frame to prevent the window from freezing. Comment it out to check it.
# pygame.event.pump()
click = pygame.mouse.get_pressed()
mousex, mousey = pygame.mouse.get_pos()
print(click, mousex, mousey, file=file)
screen.fill(BG_COLOR)
pygame.display.flip()
clock.tick(60) # Limit the frame rate to 60 FPS.
print("Ende: " + str(datetime.datetime.now()), file=file)
Hello, I am new in Pygame and for now, my Programm can track the mouse coordinates and it creates the time of the click. But i want to calculate the Speed of the Mouse from one click to the next click (in Pixels per Second).
Thanks in advance.


Use pygame.time.get_ticks() to return the number of milliseconds since pygame.init() was called.
Compute the Euclidean distance between 2 clicks and divide it by the time difference:
import math
prev_time = 0
prev_pos = (0, 0)
click_count = 0
done = False
while not done:
# This event loop empties the event queue each frame.
for event in pygame.event.get():
# Quit by pressing the X button of the window.
if event.type == pygame.QUIT:
done = True
elif event.type == pygame.MOUSEBUTTONDOWN:
act_time = pygame.time.get_ticks() # milliseconds
act_pos = event.pos
if click_count > 0:
dt = act_time - prev_time
dist = math.hypot(act_pos[0] - prev_pos[0], act_pos[1] - prev_pos[1])
speed = 1000 * dist / dt # pixle / seconds
print(speed, "pixel/second")
prev_time = act_time
prev_pos = act_pos
click_count += 1
# [...]

pygame.time.set_timer() it works incorrectly [duplicate]

I started using pygame and I want to do simple game. One of the elements which I need is countdown timer.
How can I do the countdown time (eg 10 seconds) in PyGame?

Another easy way is to simply use pygame's event system.
Here's a simple example:
import pygame
pygame.init()
screen = pygame.display.set_mode((128, 128))
clock = pygame.time.Clock()
counter, text = 10, '10'.rjust(3)
pygame.time.set_timer(pygame.USEREVENT, 1000)
font = pygame.font.SysFont('Consolas', 30)
run = True
while run:
for e in pygame.event.get():
if e.type == pygame.USEREVENT:
counter -= 1
text = str(counter).rjust(3) if counter > 0 else 'boom!'
if e.type == pygame.QUIT:
run = False
screen.fill((255, 255, 255))
screen.blit(font.render(text, True, (0, 0, 0)), (32, 48))
pygame.display.flip()
clock.tick(60)

On this page you will find what you are looking for http://www.pygame.org/docs/ref/time.html#pygame.time.get_ticks
You download ticks once before beginning the countdown (which can be a trigger in the game - the key event, whatever).
For example:
start_ticks=pygame.time.get_ticks() #starter tick
while mainloop: # mainloop
seconds=(pygame.time.get_ticks()-start_ticks)/1000 #calculate how many seconds
if seconds>10: # if more than 10 seconds close the game
break
print (seconds) #print how many seconds

In pygame exists a timer event. Use pygame.time.set_timer() to repeatedly create an USEREVENT. e.g.:
timer_interval = 500 # 0.5 seconds
timer_event = pygame.USEREVENT + 1
pygame.time.set_timer(timer_event , timer_interval)
Note, in pygame customer events can be defined. Each event needs a unique id. The ids for the user events have to be between pygame.USEREVENT (24) and pygame.NUMEVENTS (32). In this case pygame.USEREVENT+1 is the event id for the timer event.
To disable the timer for an event, set the milliseconds argument to 0.
Receive the event in the event loop:
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == timer_event:
# [...]
The timer event can be stopped by passing 0 to the time parameter.
See the example:
import pygame
pygame.init()
window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
counter = 10
text = font.render(str(counter), True, (0, 128, 0))
timer_event = pygame.USEREVENT+1
pygame.time.set_timer(timer_event, 1000)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
elif event.type == timer_event:
counter -= 1
text = font.render(str(counter), True, (0, 128, 0))
if counter == 0:
pygame.time.set_timer(timer_event, 0)
window.fill((255, 255, 255))
text_rect = text.get_rect(center = window.get_rect().center)
window.blit(text, text_rect)
pygame.display.flip()

pygame.time.Clock.tick returns the time in milliseconds since the last clock.tick call (delta time, dt), so you can use it to increase or decrease a timer variable.
import pygame as pg
def main():
pg.init()
screen = pg.display.set_mode((640, 480))
font = pg.font.Font(None, 40)
gray = pg.Color('gray19')
blue = pg.Color('dodgerblue')
# The clock is used to limit the frame rate
# and returns the time since last tick.
clock = pg.time.Clock()
timer = 10 # Decrease this to count down.
dt = 0 # Delta time (time since last tick).
done = False
while not done:
for event in pg.event.get():
if event.type == pg.QUIT:
done = True
timer -= dt
if timer <= 0:
timer = 10 # Reset it to 10 or do something else.
screen.fill(gray)
txt = font.render(str(round(timer, 2)), True, blue)
screen.blit(txt, (70, 70))
pg.display.flip()
dt = clock.tick(30) / 1000 # / 1000 to convert to seconds.
if __name__ == '__main__':
main()
pg.quit()

There are several ways you can do this- here's one. Python doesn't have a mechanism for interrupts as far as I know.
import time, datetime
timer_stop = datetime.datetime.utcnow() +datetime.timedelta(seconds=10)
while True:
if datetime.datetime.utcnow() > timer_stop:
print "timer complete"
break

There are many ways to do this and it is one of them
import pygame,time, sys
from pygame.locals import*
pygame.init()
screen_size = (400,400)
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption("timer")
time_left = 90 #duration of the timer in seconds
crashed = False
font = pygame.font.SysFont("Somic Sans MS", 30)
color = (255, 255, 255)
while not crashed:
for event in pygame.event.get():
if event.type == QUIT:
crashed = True
total_mins = time_left//60 # minutes left
total_sec = time_left-(60*(total_mins)) #seconds left
time_left -= 1
if time_left > -1:
text = font.render(("Time left: "+str(total_mins)+":"+str(total_sec)), True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
time.sleep(1)#making the time interval of the loop 1sec
else:
text = font.render("Time Over!!", True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
pygame.quit()
sys.exit()

This is actually quite simple. Thank Pygame for creating a simple library!
import pygame
x=0
while x < 10:
x+=1
pygame.time.delay(1000)
That's all there is to it! Have fun with pygame!

Another way to do it is to set up a new USEREVENT for a tick, set the time interval for it, then put the event into your game loop
'''
import pygame
from pygame.locals import *
import sys
pygame.init()
#just making a window to be easy to kill the program here
display = pygame.display.set_mode((300, 300))
pygame.display.set_caption("tick tock")
#set tick timer
tick = pygame.USEREVENT
pygame.time.set_timer(tick,1000)
while 1:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.USEREVENT:
if event.type == tick:
## do whatever you want when the tick happens
print('My tick happened')

Pygame screen doesn't seem to refresh

I've been trying to make a Chrome Dino Game, however, I'm struggling with this problem:
On every frame, it should draw a new one at the new position and delete the previous one to make it look as if it's moving. HOWEVER, it remains at its previous position and a new image appears on its next position. I did write the pygame.display.update() code at the end of my maintop.
In the last time I ran into a similar problem, I managed to make it work by drawing a background image, but this time, it doesn't work.
following are my codes:
import pygame
import os
from random import randint
import schedule
pygame.init()
assets = os.path.join(os.path.dirname(__file__), "Assets")
screen_size = (screen_width, screen_height) = (1280, 720)
screen = pygame.display.set_mode(screen_size)
clock = pygame.time.Clock()
fps = 120
bg = pygame.image.load(os.path.join(assets, "IMG_15.png"))
ground = 700
running = True
spacebaridx = 0
gamestart = False
tick_on_start = 0
obs1 = pygame.image.load(os.path.join(assets, "colourmat/light_green.png"))
pygame.transform.scale(obs1, (100, 200))
obs2 = pygame.image.load(os.path.join(assets, "colourmat/light_green.png"))
pygame.transform.scale(obs2, (120, 200))
obs3 = pygame.image.load(os.path.join(assets, "colourmat/light_green.png"))
pygame.transform.scale(obs3, (150, 200))
ls_obs = []
def create_obs():
k = randint(1, 3)
if k == 1:
info = {"type":1, "img":obs1, "x":screen_width, "y":ground - 200, "tox":2}
ls_obs.append(info)
if k == 2:
info = {"type":2, "img":obs2, "x":screen_width, "y":ground - 200, "tox":2}
ls_obs.append(info)
else:
info = {"type":3, "img":obs3, "x":screen_width, "y":ground - 200, "tox":2}
ls_obs.append(info)
schedule.every(3).seconds.do(create_obs)
while running:
dt = clock.tick(fps)
if gamestart == True:
game_ticks = pygame.time.get_ticks() - tick_on_start
schedule.run_pending()
else:
game_ticks = pygame.time.get_ticks()
for event in pygame.event.get():
if event.type == pygame.QUIT: running = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
if spacebaridx == 0: # Press space to start / to tell whether it's the first press
spacebaridx += 1
gamestart = True
tick_on_start = pygame.time.get_ticks()
else:
pass # Jump
for o in ls_obs:
o["x"] += o["tox"] * -1
screen.blit(bg, (0, 0))
for o in ls_obs:
screen.blit(o["img"], (o["x"], o["y"]))
pygame.display.update()
pygame.quit()

This issue is occurring because you aren't clearing the display within each frame. In pygame, in order to clear the display, we need to use the fill method. So in your code, at the top of your game loop before the event loop, add screen.fill((0, 0, 0)). This will fill your screen in the color black. Don't worry, the black won't be shown if you draw the background on top of it. Now, when you add a new image, the previous images won’t be displayed.
Modified Game Loop
while running:
screen.fill((0, 0, 0))
dt = clock.tick(fps)
if gamestart == True:
game_ticks = pygame.time.get_ticks() - tick_on_start
schedule.run_pending()
else:
game_ticks = pygame.time.get_ticks()
for event in pygame.event.get():
if event.type == pygame.QUIT: running = False
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
if spacebaridx == 0: # Press space to start / to tell whether it's the first press
spacebaridx += 1
gamestart = True
tick_on_start = pygame.time.get_ticks()
else:
pass # Jump
for o in ls_obs:
o["x"] += o["tox"] * -1
screen.blit(bg, (0, 0))
for o in ls_obs:
screen.blit(o["img"], (o["x"], o["y"]))
pygame.display.update()
pygame.quit()

How to set interval between two keyboard events?

I want to make the player move in maze each block at a time.
I tried using a clock and time.time() but those didn't work.
This is my game loop:
while self.running:
self.counter += 1
self.clock.tick(self.fps)
if self.counter == self.fps:
self.counter = 0
self.canUpdate = True
This is the code for movement:
if self.game.canUpdate:
if pressed_keys[K_DOWN]:
self.moveDown()
self.game.canUpdate = False
def moveDown(self):
if self.canMoveTo(self.gridx, self.gridy+1):
for sprite in self.game.sprites:
if sprite != self:
sprite.y -= self.game.gridSize
self.gridy += 1
print(self.gridy, self.game.canUpdate)
Upon one press of the down arrow gridy increment to over 500 and self.game.canUpdate remains True

You should use an event loop or pygame.event.wait if you want to move once per keypress. When you press the down key, a single pygame.KEYDOWN event with the key attribute pygame.K_DOWN will be added to the event queue. Just check if this key was pressed in the event loop and then move the sprites.
import pygame as pg
pg.init()
screen = pg.display.set_mode((640, 480))
clock = pg.time.Clock()
BG_COLOR = pg.Color('gray12')
pos = pg.Vector2(120, 80)
done = False
while not done:
for event in pg.event.get():
if event.type == pg.QUIT:
done = True
elif event.type == pg.KEYDOWN:
if event.key == pg.K_DOWN:
# This will be executed once per event.
pos.y += 20
elif event.key == pg.K_UP:
pos.y -= 20
screen.fill(BG_COLOR)
pg.draw.rect(screen, (0, 128, 255), (pos, (20, 20)))
pg.display.flip()
clock.tick(60)
pg.quit()

You can use time.sleep()
import time
time.sleep(500)
call this block with your key event, so for next key pressing, your code execution stops for 500s and then it waits for next key-press event. And moreover Counter() needs to count for 500 which needs more CPU than sleep() if you are planning something bigger.

There are several ways you can do this- here's one. Python doesn't have a mechanism for interrupts as far as I know.
import time, datetime
timer_stop = datetime.datetime.utcnow() +datetime.timedelta(seconds=10)
while True:
if datetime.datetime.utcnow() > timer_stop:
print "timer complete"
break

There are many ways to do this and it is one of them
import pygame,time, sys
from pygame.locals import*
pygame.init()
screen_size = (400,400)
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption("timer")
time_left = 90 #duration of the timer in seconds
crashed = False
font = pygame.font.SysFont("Somic Sans MS", 30)
color = (255, 255, 255)
while not crashed:
for event in pygame.event.get():
if event.type == QUIT:
crashed = True
total_mins = time_left//60 # minutes left
total_sec = time_left-(60*(total_mins)) #seconds left
time_left -= 1
if time_left > -1:
text = font.render(("Time left: "+str(total_mins)+":"+str(total_sec)), True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
time.sleep(1)#making the time interval of the loop 1sec
else:
text = font.render("Time Over!!", True, color)
screen.blit(text, (200, 200))
pygame.display.flip()
screen.fill((20,20,20))
pygame.quit()
sys.exit()

This is actually quite simple. Thank Pygame for creating a simple library!
import pygame
x=0
while x < 10:
x+=1
pygame.time.delay(1000)
That's all there is to it! Have fun with pygame!

Another way to do it is to set up a new USEREVENT for a tick, set the time interval for it, then put the event into your game loop
'''
import pygame
from pygame.locals import *
import sys
pygame.init()
#just making a window to be easy to kill the program here
display = pygame.display.set_mode((300, 300))
pygame.display.set_caption("tick tock")
#set tick timer
tick = pygame.USEREVENT
pygame.time.set_timer(tick,1000)
while 1:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.USEREVENT:
if event.type == tick:
## do whatever you want when the tick happens
print('My tick happened')
