C # Developing the game object's behavior logic method of Unity game tutorial The behavior logic of game object--methodmethod, the reader in the 1th chapter of the new script has been seen, and in the 2nd chapter on the overall introduction of the script is also introduced, then the last chapter, although the main content is variable, but at the end of the chapter in order to show the game effect, also used
In principle, a computer is a very simple thing. It is a logic processor. All the work done by a computer is finally converted into logical operations. Therefore, anything that can perform basic logical operations (non, and, and) can be used to form a computer. The idea of computer was proposed as early as the 17th century, but it can only be mechanically used. The first computer in the modern sense is implemented by electronic tubes, but its applicat
Summary of. NET logic layered architecture
I will analyze the real mysteries of the. NET layered architecture from another perspective. Layering: Some programmers with weak technical skills will think of a layer-3 architecture (BLL, DAL, and so on) when they hear it. Actually, layering is a big technical framework, the three-tier architecture only breaks down information flow through three layers for common information systems,

The difference between the line network and the variable Reg may be the most difficult for beginners of Tilde. Sometimes you have to use Reg, but sometimes you have to use wire.
In systemopengl, we will see that you can replace reg or wire type with logic type in the past.
In fact, logic improves the reg data type so that it can be driven by continuous assignments, gate units, and modules in addition to
I. Basic KNOWLEDGE Preparation:
1. The principle of the layer:
(1) Each layer is provided with an interface for Upper call.(2) The upper layer can only call the lower level.(3) Dependence is divided into two kinds: loose interaction and strict interaction.
2. Classification of Business logic:
(1) Application logic.(2) Domain logic.
3. The layer used:

Ladder logic is the main programming method used for PLCs. as mentioned before, ladder logic has been developed to mimic relay logic. the describe to use the relay logic diagrams was a strategic one. by selecting ladder

When working with data in ASP, you can benefit from using the generic software model. One of these patterns is to separate the data access code from the business logic code that controls data access or provides other business rules. In this mode, these two layers are separated from the presentation layer. The presentation layer consists of pages where the site user has permission to view or change data.ASP. NET provides a v
In many new enterprise system designs implemented using SQLServer, system designers need to make key decisions on the positioning of data structures and management application logic. SQLServer has its own programming language (Transact-SQL, TSQL). developers can use it to manage data access, code transaction logic, and transaction control. Use TSQL,

Power outage analysis, as the name suggests, is the logical analysis of the drawings for power outages. In the electrified line, a line is from a power supply, connecting a lot of equipment, power outage analysis, there are two important roles: first, see whether the shape on the drawings are connected to the normal, and the second is to see which equipment has no electricity. By giving an electrically-powered device a color (such as green), a device that has no electricity, a color (such as red

Visibility: Multiple threads can share access and manipulate the same variables, but one thread changes to a shared variable, and the other thread doesn't have to see it right away, or even never see it. Because it involves registers and cache levels.Solution:
Using the volatile keyword
Using the Synchronized keyword

, the whole process is called context switching, which is not only time consuming, but also invalidates many caches in the CPU, which is a cost.Of course, these costs are relatively relative, and these costs are acceptable if the threads actually do a lot of things, but if you just perform the counter++ in the example in this section, that would be too expensive.In addition, if the tasks performed are CPU intensive, that is, the CPU is mostly consumed, it is unnecessary to create a thread that e
