Before you start
This series is divided into two parts that can be read by programmers, architects, developers, and technology enthusiasts who are interested in improving software application design. After you have completed this series of studies, you will be able to use the best practices described in it and choose the right design patterns to solve specific problems.
About this series
This series of tutorials shows how to apply design patterns to address

to call adventureconfig: changesubscenetoselectedadventure (), and then calls adventureconfig: changesubscene (). It mainly triggers two events:
Firesubscenechangeevent: adventurescene responds to it through the onsubscenechange () function. It mainly calls adventurescene: loadsubscene () and internally calls assetloader. loaduiscreen ();
Fireadventuremodechangeevent: adventurescene responds to it through onadventuremodechanged.
Through the above analysis, we have roughly understood

Actor is also a resource that is loaded through assetloader. loadactor;
Corresponds to assetfamily. actor;
The corresponding resource package is "actor ?. Unity3d ", the package is gameobject;

Use Note:1. When a resource file is included in the framework used in the project, you need to manually add the resource files in the framework2, because the dynamic library (the framework default generated into a dynamic library) can not be shelves, we need to modify the build as a static library3, use the file command in the previous section to view the class library type, in fact, the framework of the executable file is. A file, just removed. A suffix suffix, change a vest.4, Static library d
The System Architecture mode:
Unified exception
Uniform exception handling is the first step in guaranteeing the correctness of a program, which is the first schema pattern. How to achieve this, see the previous article.
Log
The log is also a great means of ensuring that the program is correct, although the log is recorded after the error occurs. But the log is a quick confirmation of the problem and analyzes the important means of hiding the problem.

I would like to give you a detailed analysis of the photoshop software and share with you the tutorial on converting the image into imitating the effect of the architectural landscape blueprint.Tutorial sharing:First, let's look at the final result:01 open a small square file and we need to create a blueprint grid.

fact, regardless of whether it is, or java/lamp, no matter what platform, the same reason. (Big picture)In this architecture diagram, the same is true if you replace IIS with Apache,sqlserver and replace it with MySQL. A reasonable architecture is platform-independent. The most uncomfortable is some of the industry so-called master, said the large web site with ASP. No, no java/lamp good.

The most prominent part of architectural photography, in addition to the elements such as the composition of light and shadow, is the texture of the building itself, these elements of the perfect combination to form the magnificent atmosphere of the building works, then how to deal with and highlight the texture of the building itself?
Today we are sharing the secrets from the Poco talent, HDR teaches you to create super textured buildings.

This tutorial mainly uses Photoshop to turn daytime architectural photos into night effects. Many people do not know that many night movie lenses are actually taken at noon when the sun shines, with some professional camera settings and powerful post-processing, the film studio can be taken into the lens of the day at any time. This tutorial will teach you how to apply filters and adjust layers to convert photos taken during the day into night images.

The beginning of the architectural evolution is a typical lamp route: Originally developed in PHP, almost all programmers use PHP originally three servers: A Web, a database, a PHP in order to expand, start using Memcache, and then introduce the front-end cache, Then add haproxy to the cache and then MySQL sharding (very effective) using the "Squeeze everything on a single server" approach. Over the past year, two bac

The system architecture is flexible, depending on the requirements, not necessarily every layer of technology needs to be used. For example, some simple CRM systems may not require k-v

does not affect the concept model of state transition and the characteristics of server stateless.A friend with architectural design experience should be aware that, compared with stateful service design, stateless services can easily achieve the lateral scalability of system performance. By adding hardware, deploying multiple stateless services, and load balance are not constrained, while stateful service mode, session storage, sharing will bring pe
