ReadFloatVariableFromFile

Definition

float ReadFloatVariableFromFile()

Description

This function reads a floating point 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 a floating point value.

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 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.
