Listing 1. Simple Roll Roll Device Many games and game systems need dice. Let's start with the simple part: roll a six-sided dice. In fact, scrolling a six-sided dice is a random number from 1 to 6. In PHP, this is very simple: echo rand (1,6);. In many cases, this is basically simple. But in dealing with odds games, we need some better implementations. PHP provides a better random number generator: Mt_rand (). Without further study of the difference,

If you've been using PHP for a while, you should already be familiar with its array-a data structure that allows you to store multiple values in a single variable and manipulate them as a collection. Often, developers find it useful to use this data structure in PHP to sort values or array elements. PHP provides a number of sorting functions that are suitable for multiple arrays, which allow you to arrange elements within an array, and also allow you to reorder them in many different ways. In

Some functions are frequently used during php game development. For more information, see. Listing 1. simple throttling Many games and game systems require dice. Let's start with the simple part: throw a six-sided dice. In fact, rolling a six-sided dice means selecting a random number from 1 to 6. In PHP, this is very simple: echo rand );. In many cases, this is basically simple. However, when dealing with probability games, we need some better implem

with odds games, we need some better implementations. PHP provides a better random number generator: Mt_rand (). Without delving into the differences, you can think of Mt_rand as a faster, better random number generator: Echo Mt_rand (1,6);. If you put the random number generator in a function, the effect will be better. 　　 Listing 1: Using the Mt_rand () Random number generator function Copy CodeThe code is as follows: function Roll () { Return Mt

Often, developers find it useful to use this data structure in PHP to sort values or array elements. PHP provides a number of sorting functions that are suitable for multiple arrays, which allow you to arrange elements within an array, and also allow you to reorder them in many different ways. In this article we will discuss some of the most important functions in this sort. Simple sorting First, let's take a look at the simplest case: simply sort an array element from low to high, which can be

position from the imperative language to the functional language spectrum, but they all show function functions and idioms. Functional programming technology is clearly defined, but languages sometimes use different terms for the same functional concept, making it difficult to see similarities. In this article, I have compared the functional encoding styles of Scala, Groovy, and Clojure and discussed their advantages.Imperative Processing First, we will discuss a common problem and its impera

It guarantees that the user's every operation is reliable, even if the abnormal interview situation, will not damage the integrity of the background data. Just like the bank's self-service teller machine, often day can normal for the customer officer, but also inevitably touch the process of the machine suddenly the shortcomings of the situation, at this time, the transaction must ensure that the

), to use all available hardware threads in the CPU.Lambda expression OverviewIn the previous example of finding a string using a different casing scheme, what we want to do is to pass the representation of the method toLowerCase () as the second parameter into the contains () method, which requires the following work:1. Find a way to treat code snippets as a value (an object)2. Find a way to pass the code snippet above to a variableIn other words, we need to wrap a program logic into an object,

An important new feature in tiger is enumeration structure, which is a new type that allows constants to represent specific data fragments, and all of them are expressed in type-safe form. Brett McLaughlin, a tiger expert and productivity author on developerworks, will explain the definition of enumeration and explain how to apply Program Use enumeration and why it allows you to discard all old Public static final Code . As you know, the two basic construction blocks of Java code areClassAnd

Listing 1. index.html JQuery is included to ensure that a simple syntax for event management binding is applicable to different browsers and strictly follows the most common development practices. Add script markup for the leaker class and main JavaScript methods. In the development environment, it is usually better to merge JavaScript files into a single fil

Focus on Listing 7Now, many Linux® and UNIX® systems have bash shells, which are the common default shells on Linux. In this article, you'll learn how to handle parameters and options in a bash script, and how to use the shell's parameter extensions to check or modify parameters. This article focuses on bash, where the examples are run on a bash-shell Linux system. However, many other shells also have these extensions, such as Ksh, Ash, or dash, which

Without further study of the difference, Mt_rand is considered to be a faster and better random number generator: Echo Mt_rand (1,6);.

Often, developers find it useful to use this data structure in PHP to sort values or array elements. PHP provides some sort functions that are appropriate for a variety of arrays, which allow you to arrange elements within an array, and also allow you to reorder them in many different ways. In this article we will discuss some of the most important functions in this sort. Simple sort First, let's look at the simplest scenario: simply sort an array element from low to high, which can be arranged

; 10.0) {return new Shardid (1); else {return new Shardid (0); } } } As you can see in Listing 1, if the persisted object is a Race, the distance is determined and (therefore) a shard is selected. In this case, there are two shards: 0 and 1, where Shard 1 contains more than 10 miles of the race, and shard 0 contains all the other races. If you persist a Runner or other object, the situation is slightly more complex. I have coded a logi

: Listing 1. eval Problems The Code is as follows: Var reference ={}, props = "p1 ";Eval ("reference." + props + "= 5 ")Var reference ={}, props = "p1 ";Reference [props] = 5 Code with "eval" is more than 100 times slower than code without "eval. The main reason is that JavaScript code performs operations similar to "pre-compilation" before execution: First, it creates an activity object in the current execution environment, and set the variables

some common problems that may be difficult to detect. This section will discuss several debugging tools that greatly simplify the process of detecting and identifying memory problems. MEMWATCHMEMWATCH, written by Johan Lindh, is an open-source C-language memory error detection tool. You can download it by yourself (see references later in this article ). After adding a header file in the Code and defining MEMWATCH in the gcc statement, you can track memory leaks and errors in the program. MEMWA
