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.
This function returns a floating point value.
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.ReadFloatVariableFromFile
