[英]random.randint() generating a consistent pattern
我一直在使用pygame
開發基於網格的應用程序,但遇到了一個奇怪的問題。
我正在生成一個圖塊list
,每個圖塊都可以有 3 種隨機顏色中的一種。 不過,每次我運行該程序時,我都會得到一個相當一致的模式。
所有這些測試都是緊接着進行的,並且在測試之前的所有運行中都出現了類似的結果,右下角有一個巨大的單色斑點。
這是我的瓷磚代碼
from enum import Enum
class Colour(Enum):
RED = 1
GREEN = 2
BLUE = 3
class Tile():
def __init__(self, _map, x : int, y : int, colour = 1):
self.x = x
self.y = y
self.map = _map
self.colour = Colour(colour)
def PrintInfo(self):
print("x: " + str(self.x) + "\ny: " + str(self.y) + "\nCol: " + str(self.colour.name))
這是制作瓷磚陣列的地方,(生成隨機數的地方)
from Tile import Tile
from random import randint
"""Map class creates a 2d array of tiles, and allows individual tiles, or
groups of tiles to be returned."""
class Map:
def __init__(self, width : int, height : int):
self.map = []
#Create a 2d array of tiles.
self.map = [[Tile(self, i, j, randint(1, 3)) for i in range(width)] for j in range(height)]
def PrintInfo(self):
#Print the info of each tile. use GetTile(x, y).PrintInfo() tp get
#individual tile into
for t in self.map:
t.PrintInfo()
def GetTile(self, x: int, y: int):
#Get tile from coords
return self.map[x][y]
這是根據隨機數制作視覺組件的地方
def Main(self):
#Create an array of data objects
self.map = Map(8, 8)
#Create dictionary to connect data object to display object
self.tileToObjDict = {}
for i in range(8):#change these from constants after testing
for j in range(8):
t = self.map.GetTile(i, j)#get tile at current position in loop
#t.PrintInfo()
bobj = BoxObject(self.win, t.x*self.gridSpacing, t.y*self.gridSpacing, t.x*self.gridSpacing+self.gridSpacing,
t.y*self.gridSpacing+self.gridSpacing, str(t.colour.name).lower())#Create onject based on info
self.objects.append(bobj)#add display object to render list
self.tileToObjDict[t] = bobj#connect tile to display obj in dictionary
不需要,但是組裝可視化組件的代碼
#Basic Object
class BoxObject(Object):
def __init__(self, surface, x1 = 0, y1 = 0, x2 = 0, y2 = 0, colour = 'grey', hitbox = Hitbox(EventManager())):#Take a surface, 4 coords, a colour, and an optional hitbox to manage events
super().__init__(Box(surface, Rectangle(x1,y1,x2,y2).GetCorners(),ColourManager().GetColour(colour)),
hitbox)
#draw the object for 1 frame to reference
self.drawn = draw.rect(self.graphic.surface, self.graphic.colour,(self.graphic.coord1, self.graphic.coord2))
def Update(self):
if self.visible:#Draw the object
draw.rect(self.graphic.surface, self.graphic.colour,(self.graphic.coord1, self.graphic.coord2))
if Hitbox == None:
return
if len(self.hitbox.eventM.eventList) > 0:#If the hitbox has any events to manage, manage them
for e in self.hitbox.eventM.eventList:
e()
顏色模塊
from pygame import Color
class ColourManager:
colourDict : {}#holds custom colours
def __init__(self, defaultColours = True):
self.colourDict = {}
if defaultColours:
self.AddBasicColours()
def AddColour(self, name : str, _r : int, _g : int, _b : int, _a : int = 255):
self.colourDict[name] = Color(_r, _g, _b, _a)
def GetColour(self, name : str) -> Color:
return self.colourDict.get(name)
def PrintColours(self):
for key in self.colourDict.keys():
print(key)
def AddBasicColours(self):
self.AddColour('red', 255, 0, 0)
self.AddColour('green', 0, 255, 0)
self.AddColour('blue', 0, 0, 255)
self.AddColour('grey', 100, 100, 100)
def LoadColourSheet():
"""TODO: Allow many colours to be loaded at once from txt file"""
感謝任何幫助,無論是有效的替代隨機化方法,還是我的代碼可能導致此問題的問題。
9769953 關於它是模式而不是隨機化是正確的。 我忘記了 pygame 是如何渲染形狀的,同樣的模式是因為單個塊比它們應該的大得多。 我不得不改變 x2 和 y2。
#Box object: screen to draw it to, x1, y1, x2, y2, colour (x1, y1) = top left corner of box, x2 = width, y2 = height
bobj = BoxObject(self.win, t.x*self.gridSpacing, t.y*self.gridSpacing, self.gridSpacing, self.gridSpacing, str(t.colour.name).lower())#Create object based on info
