WriteFloatVariableToFile

Definition

WriteFloatVariableToFile(float value)

Description

This function writes a floating point value to the currently open file. Before writing information to the file, make sure that you have opened the desired file for writing with the OpenFileForWriting function.

Parameter

value

Specifies a floating point value to write to the currently opened file.

Example

fVar = 0.0

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

   --Create and open file to write data
   OpenFileForWriting("Lev1/level1.bin")
   WriteFloatVariableToFile(2.0)
   CloseFile("Lev1/level1.bin")

   --Open File to load data
   OpenFileForReading("Lev1/level1.bin")
   fVar = ReadFloatVariableFromFile()
   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 the floating point value 2.0 by the WriteFloatVariableToFile 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 a floating point variable from the level1.bin file with the ReadFloatVariableFromFile() function. In our example, value of fVar is 2.0 after reading it. Finally, we close the file by the CloseFile function.
