ReadIntVariableFromFile

Definition

int ReadIntVariableFromFile()

Description

This function reads an integer variable from the currently open file. Before reading information from the file, make sure that you have opened the desired file for reading with the OpenFileForReading function.

Return Value

This function returns an integer value.

Example

iVar = 0

function Init()
   --Create a folder in Assets/Data/ path
   CreateFolder("Lev1")

   --Create and open file to write data
   OpenFileForWriting("Lev1/level1.bin")
   WriteIntVariableToFile(3)
   CloseFile("Lev1/level1.bin")

   --Open File to load data
   OpenFileForReading("Lev1/level1.bin")
   iVar = ReadIntVariableFromFile()
   CloseFile("Lev1/level1.bin")
end

First, using the CreateFolder function, we create a folder called “Lev1” in the Assets/Data/ path. Then, using the OpenFileForWriting function, we open the level1.bin file located in the Assets/Data/Lev1/ path for writing. After writing an integer value by the WriteIntVariableToFile function, we close the file by the CloseFile function.

Then, using the OpenFileForReading function, we open the level1.bin file located in the path Assets/Data/Lev1/ for reading and read an integer variable from the level1.bin file with the ReadIntVariableFromFile() function. In our example, value of iVar is 3 after reading it. Finally, we close the file by the CloseFile function.
