The purpose of this paper is to compare the advantages and disadvantages of these four methods and to give a solution.1.

The Sproto library author uses the lua5.2 new Library bitwise Operators in the code, and does not match the lua5.1 environment we use, so we can replace lua5.2 with lua5.1 and Bit.numberlua. Operators.2. Also tried to use the Protoc-gen-lua, but the solu

As a network game, it is inevitable to interact with the server, the data structure on the PROTOBUF is a good solution, the use of protobuf in Lua there are a variety of options, where the use of the cloud wind of the PBC.
First go to this web site to download the build tool http://repo1.maven.org/maven2/com/google/protobuf/protoc/, my side of the download of version 2.5. Put the Protoc.exe in the designated place, and then copy the proto file, for be

But the PBC's
point P is in a triangle, three vectors are used: AB × ap, ap × ac, pb × pc parallel to the same direction (they are also in the same direction as the vector AB × ac), because these three vectors may be 0, it is quite troublesome to directly judge the parallel direction of them, but considering that AB × ac cannot be 0, it is difficult to directly judge the "vector: AB × ap, ap × ac, and pb × pc are all parallel to AB × ac.
Area Method: When point p is within the Triangle abc, the area of the
