我一直在制作一个“小行星”重制版。然而,我无法使对象以随机运动方式移动。我确定这需要使用向量,但是我不知道如何为每个单独的小行星随机生成一个向量。
我正在寻找类似于这个小行星游戏中所显示的运动方式,但我甚至不知道如何开始。这是我目前的代码:
import pygame as game
import random as r
import math
game.init()
game.display.set_caption("Asteroids")
screen = game.display.set_mode([800,600])
time=0
gameon=True
bgcolor = game.color.Color("#f6cb39")
black=game.color.Color("black")
badguy = game.image.load("asteroid.png")
badguy = game.transform.scale(badguy, (50, 50))
badguys=[]
SPAWNENEMY=10
CLOCK=11
game.time.set_timer(SPAWNENEMY,800)
game.time.set_timer(CLOCK,1000)
font=game.font.Font(None,20)
timetext=font.render("Time: 0", 0, black)
while gameon:
screen.fill(bgcolor)
event=game.event.poll()
if event.type==SPAWNENEMY:
bgbox = game.Rect(badguy.get_rect())
bgbox.x = r.randint(50,800)
bgbox.y = r.randint(50,600)
badguys.append(bgbox)
if event.type==game.QUIT:
gameon=False;
for bg in badguys:
'''
This is where I tried to put the mocment code,
but I was unableto get randmom movments,
only for asteroids to randomly appear or consistently
move in one direction something like "bg.x+=2"
'''
for bg in badguys:
screen.blit(badguy,(bg.x,bg.y))
game.display.flip()
如果有一点长,我向您道歉,我不知道还能删掉什么来创建一个MCV。
