I am confused with public, private, protected, and this and self. I have already written a blog post about public, private, and protected. The following describes how to use this, self, and parent. 1, this 1. to use this, you must be in a situation like this. Otherwise, it will report an error: Fatal error: Using $ this when not in object context.2. this can call methods and attributes in this class, or call methods and attributes that can be called in the parent class. II. self 1. self can ac

One, this 1, to use this, you will have a situation of the image, otherwise it will error, Fatal error:using $this when the not in object context.2,this can call methods and properties in this class, or can call the adjustable methods and properties in the parent class Two, self 1,self can access static properties and static methods in this class, and can access static and static methods in the parent class.2, when using self, you can not instantiate the Third, parent 1,parent can access static

In fact, it is easy to understand. after clearing the file, it is of course empty if you do not enter the content. 2,> Usage [Zhangy @ localhost ~] $ Echo "2222"> 2.txt [Zhangy @ localhost ~] $ Cat 2.txt 2222 [Zhangy @ localhost ~] $ Echo "2222"> 2.txt [Zhangy @ localhost ~] $ Cat 2.txt 2222 2222 As shown in the preceding example,> When redirected to a file, the output is written to the end of th

Application Scenario Description: if we need to develop a tank for the game, in addition to a variety of different types of tanks, we also hope to add one or more of the following features for it in different occasions, for example, infrared night vision functions, such as amphibious functions, such as satellite positioning functions; In general, we may do this during programming: // Define the abstract class of the

example below: We will create two classes, tank and map, inherited from Sprite and tiledlayer, which both implement the actor interface. Create Frame Animation for tank, create dynamic graph blocks for map, and display them in scenemain. First, we can copy the example in Chapter 10 to create a new project and copy the org. yexing. Android. Games. Common package used in Chapter 8 to the project. Create a

Otherwise, it will report an error: Fatal error: Using $ this when not in object context.2. this can call methods and attributes in this class, or call methods and attributes that can be called in the parent class. Ii. self 1. self can access static attributes and static methods in this class, and can access static attributes and static methods in the parent class.2. When using self, you do not need to instantiate 3. parent 1. parent

Java Dynamic proxy ModeProxy: a role represents another role to implement some specific functions.For example, the relationship between producers, middlemen, and customersCustomers who buy products do not directly deal with producers, nor do they know how the products are produced. Customers only deal with middlemen, and middlemen can carry some packaging on the products, provide some after-sales services. Proxy mode has three roles: 1. Abstract topic role 2. Proxy topic role 3. Real-time proxy

event from the tank to combine, waiting when one of the tanks is empty.Off-topic: Let's analyze the characteristics of this water tank. It is in order to save, advanced events first taken out, this feature is not very familiar with it? Yes, this is what we know the queue, the water tank in the zip inside the implementation is the queue, interested in the source

Tools: Sketch 3.3.2 First, draw a water tank first. Create a new rounded rectangle, adjust the transparency, and then resize. The angle of the water tank, I was directly adding a stroke to draw. The next step is to add the edge of the tank and draw the concave. Take a look at all the styles first. Because the water

Recently learning swing programming, according to the teacher's teaching video learning using java.awt.*, javax.swing.*, java.awt.event.* package for a simple tank war game programming, Learning JFrame, JPanel and other containers and components of the use of Learn the various ways to draw graphics using graphics, as well as some event monitoring and processing methods.JFrame This class is inherited in the current study, and then called Kick to show h

He plans to use this water polo to play games. First, the supervisor has prepared a water tank with an infinite capacity. At the beginning, the water tank is empty. Then, the water

Method One: Particle systemsOSG particle systems have their own defined modules, such as osgparticle::explosioneffect (Explosion simulation), Osgparticle::smokeeffect (smoke simulation); Osgparticle:: Fireeffect (flare Simulation). I think the smoke simulation and flare simulation can be used to display the alarm effects. OSG Adding a osgparticle particle effect to the scene:Add a custom Osgparticle instance to the scene to simulate the soot generated when the
