today!First, animator component chapterThe Animator component is an animation component used by the unity3d mecanim animation system. This component uses the Animator controller to control the animation. is the protagonist of our project today, a female warrior with a left hand holding a shield and a sword on his right hand. let's start by creating a Animator Controller and name it Swordgirlcontroller , double-click Open Animator form, according to our discussion of state changes, we are able

Bitwise operators treat operands as a series of individual bits, rather than as a numeric value. So before this, you have to mention what is "bit":Values or characters are stored in memory as 0 and 1 sequence, each 0 and 1 is called 1 bits, for example, 10 binary data 2 is stored in the computer as 0 0 0 0 0 0 1 0, when we change the in-memory bit value, this value represents the meaning of the changes, such as moving 2 forward, Now the storage unit becomes 0 0 0 0 0 1 0 0, this value represents

define and use the parseint () function to parse a string and return an integer. The syntax parseint (string, Radix) parameter describes the string required. The string to be parsed. Radix is optional. Represents the cardinality of the number to parse. The value is between2 ~ 36between. If the argument is omitted or its value is0, the number will be parsed based on 10. If it starts with "0x" or "0X", it will be 16as the cardinality. If the parameter i

Directly describe the scenario in detail: server A forwards data to server B through curl, and server A forwards millions of data entries per hour. Curl requests a 0-byte file on server B, as long as the request is recorded in the nginx log of server B. Now we can directly describe the scenario in detail through two: Server A will passcurlData is forwarded to server B, and server A forwards millions of data entries per hour.curlThe request is0-Byte Fi

Each byte of the memory is identified by a unique number ( Address ) , A set of all possible addresses is called a virtual address space ( Virtual Address Space ). A virtual address space is a conceptual image presented to a machine-level Program ( Image ) , The specific implementation uses random access to memory Ram , Disk storage, special hardware and OS The combin

InputStream reads bytes from the input data stream, which mainly describes its Read method.* InputStream This abstract class is the parent class for all classes that represent byte input data streams. You need to define a subclass of InputStream for your application.* This subclass needs to provide a method to return the next byte of the input stream.Explanation of Read (byte[]) and read (Byte[],int off,int len) for InputStream in the JDK API:Read Public intReadbyte[] b)throwsIOException reads a
