当我学习蟒蛇的时候,我试着开发一个简单的游戏。游戏并不复杂,随机的汽车(也就是正方形)在屏幕的右边产卵,然后向左行驶。我们是一只海龟,试图避开它们,并使它达到屏幕的顶端。
问题是我下面的代码不是同时生成两个对象,而是只生成一个对象。
from turtle import Screen
from turt import Turt
from spawnpoint import SpawnPoint
from cars import Car
import random
screen = Screen()
screen.setup(1000, 700)
screen.title("Cars
我第一次尝试学习使用def,这个错误出现了。
Traceback (most recent call last):
File "C:\Users\Hp\PycharmProjects\whack a mole\main.py", line 36, in <module>
mole_spawn(600, 440)
TypeError: 'int' object is not callable
有多种答案来解决这个问题,我看到了很多答案,但我不知道该怎么做。
代码(只是我认为需要的部分代码)
def mole_spawn(molepos1,
产卵功能是如何工作的?
var max_bollar = 15;
var i = 0;
var timecounter = 0;
var bollarcounter = 0;
var spawn_delay = 5;
var min_spawn_delay = 25;
var max_spawn_delay = 500;
var balls = [];
function spawn(i)
{
var boll = {x: random(totalWidth), y: 0};
circle(boll.x, 0, 10, "blue");

我想知道如何以随机的速度产生敌人。我在互联网上到处寻找解决方案,但似乎没有一个接近(或者可能我没有足够的努力,我不确定。如果有解决方案,请一定要分享)。
如果我能在游戏开始后的一段时间内获得随机的速度,那就太好了。
我目前有以下代码。
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class SpawnEnemies : MonoBehaviour {
//Variable to store the enemy prefab

我的iMAC上安装了node-gyp:

OSX手册页介绍了POSIX_SPAWN_SETEXEC系统调用中的posix_spawn位:
POSIX_SPAWN_SETEXEC
Apple Extension: If this bit is set, rather than returning to the caller,
posix_spawn(2) and posix_spawnp(2) will behave as a more featureful execve(2).
任何人都知道,在调用启用posix_spawn()的posix_spawnattr_setflags之后,普通的POSIX_SPAWN_SETEXEC和POS
如何使用child_process应用程序中的“ReactJS”模块?

这些语法失败:

const ls = cp.spawn('ls', ['-al']);

我正在创建一个无限的运行器,在spawn脚本中,它总是出现这个错误消息,并且不知道如何修复它: Assets/Scripts/Spawn.cs(16,14):error CS0542:`Spawn.Spawn()':成员名称不能与它们的封闭类型相同。

我最近尝试为我们的项目做一个干净的安装。但是现在在Ubuntu 17.04上安装npm失败了。我已经更改了node、npm、node-gyp和python的版本,但没有成功。
这是由于node-gyp的更改还是其他原因?运行:
node-gyp rebuild

我只是想打开一个irb窗口并输入命令。这曾经是有效的,但不知何故现在它被打破了:

我试图在Windows Subsystem for Linux上通过yarn add node-opus安装node-opus (我不确定这是否可行,但我正在尝试),但在此过程中遇到了错误:
看起来主要的错误是:gyp ERR! stack Error: not found: make,但我觉得这是一个误导性的错误,因为在此之前我已经安装了其他包,一切正常吗?

好的,如果我使用这段代码在屏幕顶部随机生成球,我如何让它们向下移动:

var min_spawn_delay = 25;
var max_spawn_delay = 500;
function spawn(i)
