It's basically a vertical scroller game but the given issue is the character only moves when the keys are tapped, not held.

What I want is to have the character move while the key is pressed just like Graal, without having to tap for example the up key continually.

Language : Python

PHP Code:

import pygame
import time

pygame.init()

window_width = 800
window_height = 600

black = (0,0,0)
white = (255,255,255)

gameDisplay = pygame.display.set_mode((window_width,window_height))
pygame.display.set_caption("Trunul")
clock = pygame.time.Clock()

background = pygame.image.load("background.png")
charImage = pygame.image.load("character_up.png")

def character(charX,charY):
    gameDisplay.blit(charImage, (charX,charY))

bg = -600
bgMin = -600
bgMax = 0

charX = (window_width * 0.45)
charY = (window_height * 0.45)

crashed = False

while not crashed:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            crashed = True

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP and bg < bgMax:
                charImage = pygame.image.load("character_up.png")
                bg += 10
                    
            if event.key == pygame.K_DOWN and bg > bgMin:
                charImage = pygame.image.load("character_down.png")
                bg -= 10
            if event.key == pygame.K_RIGHT and charX < 750:
                charImage = pygame.image.load("character_right.png")
                charX += 10
            if event.key == pygame.K_LEFT and charX > 0:
                charImage = pygame.image.load("character_left.png")
                charX -= 10

    gameDisplay.fill(white)
    gameDisplay.blit(background, (0,bg))
    character(charX,charY)
    pygame.display.update()
    clock.tick(60)

pygame.quit()
quit() 


 

I've never used py game so I don't know what kind of solution it surely already has, but have you tried wrapping the key pressed stuff in a loop? That code isn't indented on my phone so I can't really tell if it already is.  

Your best friend is stackoverflow.

In particular it looks as though you should be replacing your keydown event conditional with

PHP Code:

   key = pygame.key.get_pressed()
   
   if key[pygame.K_UP] and bg < bgMax: 
       charImage = pygame.image.load("character_up.png") 
       bg += 10 

   #etc...
