Sound effect when mouse hovers over object? - python

So i'm trying to set up this thing where a sound effect is made whenever the player "hovers" their mouse above a label.
This is the image: https://gyazo.com/ca251495b348ab8cd27f7328c84518e8
I've tried looking for solutions, I have found one previously but it did not work when adding sound to it.

What I'm expecting is a sound effect to be made whenever the mouse goes over a label, however, the output from the program is that nothing plays or happens.

I think the issue is the processing of the events in event_handler(), which consumes all the events. Then the Button class handle_event() function is starved of events (also this function is never called). It's a good idea to handle events in a single place in the code, and call out from there.
If the OP's code did work, it looks to be constantly re-playing the sounds too. The mouse-move generates a lot of events, so the triggering of playing the sound needs to only play on the initial entry into the button's rectangle. Whereas the mouse movement handler is re-playing on every event inside the button's rect.
Below is some example code where I took your buttons, and modified them to handle the hovering in a "edge-triggered" manner. This means it only triggers when the "hovered" state first becomes true, not while it's true (which would be "level-triggered")
Note: It does not actually play the sound, as I don't have a sound-file handy. It just does a print().

How to change the rendered numbers on this code

The program consists in generating 2 random numbers, rendering them on screen (with the '+' symbol, because it's a sum) and expecting the user to put the result of the sum on the box entry. The code already has a function that generates 2 random numbers (x and y), and another one that renders them on screen (besides the score). Here is the code:
import pygame
import random
from InputBox import InputBox
pygame.init()
clock = pygame.time.Clock()
surface = pygame.display.set_mode((600, 400))
pygame.display.set_caption("Projecte MatZanfe")
font = pygame.font.SysFont('comicsans', 50)
base_font = pygame.font.Font(None, 32)
user_text = ''
color_active = pygame.Color('lightskyblue3')
running = True
points = 0
def start_the_game():
x = random.randint(0, 10)
y = random.randint(0, 10)
is_correct = False
return x, y
def display_the_game(x, y):
# Variables
z = x + y
surface.fill((255, 70, 90))
text = font.render(str(x) + "+" + str(y), True, (255, 255, 255))
text_surface = base_font.render(user_text, True, (255, 255, 255))
surface.blit(text, (260, 120))
input_box.draw(surface)
punts = font.render("PuntuaciĆ³: " + str(points),True, (255,255,255))
surface.blit(punts, (350,30))
x, y = start_the_game()
input_box = InputBox(190, 250, 200, 32)
while running:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
else:
result = input_box.handle_event(event)
if result != None:
if int(result) == int(x) + int(y):
# TODO: when the user is right
points = points + 5
start_the_game()
pygame.display.update()
display_the_game(x, y)
pygame.display.update()
else:
# TODO: when the user is wrong
start_the_game
pygame.display.update()
display_the_game(x, y)
pygame.display.update()
display_the_game(x, y)
pygame.display.update()
pygame.quit()
I need the program to generate two new random numbers if the result is right and render them, apart from adding 5 points to the "PuntuaciĆ³" that appears up to the right (done). If the user is wrong, it just needs to generate 2 new random numbers, and render them (the score doesn't have to change).
Here is the code from the imported InputBox.

user_text = ''

def __init__(self, x, y, w, h, text=''):
self.rect = pygame.Rect(x, y, w, h)
self.color = COLOR_INACTIVE
self.text = text
self.txt_surface = FONT.render(text, True, self.color)

self.rect.w = width
def draw(self, screen):
# Blit the text.
screen.blit(self.txt_surface, (self.rect.x+5, self.rect.y+5))
# Blit the rect.
pygame.draw.rect(screen, self.color, self.rect, 2)
def main():
clock = pygame.time.Clock()
input_box2 = InputBox(190, 250, 200, 32)
input_boxes = [input_box2]
done = False

All you have to do is to create new values for x and y and to reset the input box:
while running:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
else:
result = input_box.handle_event(event)
if result != None:
if int(result) == int(x) + int(y):
points = points + 5
# create new random numbers
x, y = start_the_game()
# reset input box (just create a new box)
input_box = InputBox(190, 250, 200, 32)
display_the_game(x, y)
pygame.display.update()
pygame.quit()

How to add a blinking cursor in pygame?

so I was trying to add blinking cursors for my text. I don't know why the cursor only appears at y=0, not at each text box. I was trynna add a cursor for each box when active and stop blitting when not active. I suspect it goes wrong because I got my declaration wrong or the blitting part. Can anyone point out where it goes wrong/ how to fix it? Thanks

All you need to do is to set the position of the cursor. Get the right center position of the bounding rectangle of the text and set the left center position of the cursor:
class InputBox:
# [...]
def draw(self, screen):
# Blit the text.
screen.blit(self.txt_surface, (self.rect.x + 5, self.rect.y + 10))
# Blit the rect.
pygame.draw.rect(screen, self.color, self.rect, 1)
# Blit the cursor
if time.time() % 1 > 0.5:
# bounding rectangle of the text
text_rect = self.txt_surface.get_rect(topleft = (self.rect.x + 5, self.rect.y + 10))
# set cursor position
self.cursor.midleft = text_rect.midright
pygame.draw.rect(screen, self.color, self.cursor)
I believe your problem is in the __init__() of your InputBox class.
class InputBox:
def __init__(self, x, y, w, h, text=''):
self.rect = pygame.Rect(x, y, w, h)
self.color = color
self.text = text
self.txt_surface = text_font.render(text, True, self.color)
self.active = False
self.score = 1
# Cursor declare
self.txt_rect = self.txt_surface.get_rect()
self.cursor = pygame.Rect(self.txt_rect.topright, (3, self.txt_rect.height + 2))
self.text_surface is the result of a call to the .render method of a pygame.font.Font object. This method-call returns a pygame.Surface object. The Surface object returned, however, doesn't have a position yet. Therefore, in the line where you have self.txt_rect = self.txt_surface.get_rect(), the pygame.Rect object that is returned has by default its topleft coordinate at (0, 0) (see the documentation).
This is easily fixed. You just need to replace self.txt_rect = self.txt_surface.get_rect() with self.txt_rect = self.txt_surface.get_rect(topleft=(x, y)).

how do i connect a page to a button - pygame?

I have a menu with 3 buttons. I want one of the buttons to connect to my game page which I have but am not sure how to make this happen. So I want the "game" button to lead to the screen which has the actual game (like the screen where you play the game). i am trying to figure out how to connect a page to a button in this pygame.

Every page or stage has similar elements - create items, draw, update, handle events, mainloop - which you can put in class to separate one stage from another.
At start create MenuStage and run its mainloop(). When you press button in MenuStage then create GameStage and runs its mainloop(). To go back from GameStage to MenuStage use button (or other event) to set self.running = False to stop GameStage.mainloop and go back to MenuStage.mainloop
This example doesn't use your code but it shows how Stages would work.

EDIT: Image which I made long time ago:

Detecting mouseover and making a sound when the mouse is over it?

So im setting up a main menu for the program I'm making and I was planning to have a beeping sound for whenever a mouse hovers above a button.
The thing is, I have the button labels on my image already, so i don't really know how i could incorporate this.

This is my whole code and I'm not sure what to do with adding buttons.

It doesn't matter where you have button label - you need only its positon and size (x,y,width,height) or its pygame.Rect to compare with mouse position.
Rect has even function collidepoint to check collision with point and it can be mouse position.
if button_rect.collidepoint(mouse_position):
print("Mouse over button")
EDIT:
It is my code from GitHub with simple example with hovering button using class Button which changes color when mouse is over button (hover). It uses Rect.coolidepoint in Button.handle_event(). Maybe it can help you.

Position of an image not updating the way I want it to in PYGAME

My objective is to make a cannon fire a cannonball in a linear path. I have been playing around with some algorithms for quite a bit, but I cannot get one fluid motion, instead the position updates in chunks and I'm not sure how to evade this problem. Here is my code:

Thanks! Any help is greatly appreciated.
You need to add the velocity of the object to its position in each frame in order to move it. I also pass the delta time to the update method and multiply it with the velocity to make the object move self.v pixels per second.

I've also tried to improve and simplify a few more things. Take a look at the comments.
