Sometimes when you import fbx, you don’t need to create material, you set importMaterials to false, and if you hit AssetBundle on fbx, you’ll get Default-Material and Stander 1Getting into the bag, resulting in resource redundancy.
Solution: add the following code to AssetPostprocessor:
public Material OnAssignMaterialModel(Material m,Renderer r)
{
var importer = assetImporter as ModelImporter;
if(importer != null && importer.importMaterials == false)
{
return CommonMaterial; //A material resource stored locally}return null;

I saw this code in the code today:
typedef typename RefBase::weakref_type weakref_type;
At first I couldn’t figure out why I wanted to add a typename, but later I searched it to find out that the keyword was purposeful:
If you don’t add this keyword, the compiler doesn’t know what RefBase:: weakref_type is. It may be static member variable, or static member function, or internal class.
Add this keyword to manually tell the compiler: RefBase:: weakref_type is a type.
Example:
template<typename T>
class A {
public:
typedef T a_type;
};
template<...
Summary
Not many people have a thorough understanding of the internal structure and patterns of GPIO (General Purpose Input and Output) processors. Recently, Baidu has searched for a large amount of information on this part, and there is no consensus on many of these issues.This article lists all the questions that IO involves as far as possible, explains clearly the questions that have definite answers, and puts forward the questions where there are still questions for discussion.
Generally speaking, IO’s functional modes can be roughly divided into three categories: input, output and ...
First, preface
NET CoreIt’s getting more popular because it has the power of the original. NET Framework running on multiple platforms. Kafka is rapidly becoming the standard messaging technology in the software industry. This article briefly introduces how to use.NET (Core) and Kafka to implement NL.Target of OG.
In the daily project development process, Spring Boot + Logback in the Java system is easy to access Kafka to achieve log collection, in. NET and. NET Core has been accustomed to using NLog as a log component. In order to make the micro service ringIn the context of dotnet and...
In the last chapter, we introduce the one to one push mode. This chapter focuses on the next group push and multi person push.
Groups use methods primarily: Groups. Add (Context. ConnectionId, groupName); add different connection IDs to the same group name
The following is a demonstration of the functions of group chat.
Server code:
/// <summary>
/// Send to specified group/// </summary>
public void CallGroup(string fromname, string content)
{
string groupname = Context.QueryString["groupname"]; //Get the user name sent by the c...
