I'm making the program, that blits the 2D array as 2D map of tiles. The self.tile_size variable is used to scale the tile image that will be blit. I want the Q to make it smaller, and E to make it bigger. The problem is, that output in in pygame window is not what i wanted. The image in link shows what happened, when i ran a program and tried to make image bigger. Image of output
Here's my code:
import pygame
from pygame.locals import *
pygame.init()
import math, sys, os, random, time
from a_star import *
tiles_list = [
pygame.image.load('Floor.png'),
pygame.image.load('Wall.png'),
]
PLAN_W = 20
PLAN_H = 20
PLAN_STATUS = [[True for i in range(PLAN_W)]for j in range(PLAN_H)]
OBSTACLES = [
[0,0],
[0,1],
[0,2]]
obsta(OBSTACLES, PLAN_STATUS) # function imported from a_star that change PLAN_STATUS cells from OBSTACLES to False
class World():
def __init__(self):
self.screen_width = 800
self.screen_height = 600
self.screen = pygame.display.set_mode((self.screen_width, self.screen_height))
self.clock = pygame.time.Clock()
self.bg_color = (255,255,255)
self.tile_size = 48
self.map_status = PLAN_STATUS
self.tiles_list = tiles_list
self.scale_change = 0
self.run()
def scale_tiles(self):
print(self.tile_size)
self.new_list = []
for i in self.tiles_list:
i = pygame.transform.scale(i, (self.tile_size, self.tile_size))
self.new_list.append(i)
self.tiles_list = self.new_list
def render_map(self):
print(self.tile_size)
'''
self.screen.fill(self.bg_color)
for x in range(PLAN_H):
for y in range(PLAN_W):
if self.map_status[y][x]:
tile = self.tiles_list[0]
elif not self.map_status[y][x]:
tile = self.tiles_list[1]
self.screen.blit(tile, (x*self.tile_size, y*self.tile_size))
'''
self.screen.blit(self.tiles_list[0], (400, 300))
def run(self):
while True:
self.events = pygame.event.get()
self.keys = pygame.key.get_pressed()
self.mouse_pos = pygame.mouse.get_pos()
self.mouse_but = pygame.mouse.get_pressed()
#UPDATE
self.screen.fill(self.bg_color)
#self.scale_tiles()
self.render_map()
pygame.display.flip()
#EVENTS
if self.keys[ord('e')] == 1:
self.tile_size += 1
self.scale_tiles()
if self.keys[ord('q')] == 1:
self.tile_size -= 1
self.scale_tiles()
'''for event in pygame.event.get():
if event.type == pygame.KEYDOWN:

self.scale_change = -1
if event.key == pygame.K_e:
print('e')
self.scale_change = 1
if event.type == pygame.KEYUP:
if event.key == pygame.K_q or event.key == pygame.K_e:
print('stopped key')
self.scale_change = 0'''
self.clock.tick(50)
if __name__=="__main__":
main = World()
Where's the problem in my code? Thank you for the help
Use the images/surfaces in the original, global tiles_list to create the new_list not the already scaled images in self.tiles_list, otherwise it seems to increase the impreciseness with every scaling.
for i in tiles_list: not for i in self.tiles_list:.
