Hi guys, this is the first tutorial in my advanced modding tutorial series (The GTs tag stands for "Geforces tutorials" FYI). Anyway, lets get right to it!

How to write to a file:

PrintWriter writer = new PrintWriter("tutorial.txt"); //This will create a .txt file named "tutorial" in your .minecraft folder

writer.println("5,true") //This will print "5,true" into the tutorial.txt file
writer.close(); //This closes the .txt file when your done editting it.

//And thats it 

How to read a file:

Scanner file = new Scanner(new File("tutorial.txt")); //This loads the tutorial.txt text file into a scanner
scanner.useDelimiter(","); //This tells Java that our variables (5, true) are comma-separated.

int number;
boolean shouldPrint;

//-------------------- This whole if statement loads the two variables into variables that we can use.
if(scanner.hasNextInt()){								
	number = scanner.nextInt();
}else if(!scanner.hasNextInt() && scanner.hasNextBoolean()){
shouldPrint = scanner.nextBoolean();
}
//---------------------

How to use these things:

public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9){

	 //INSERT READING CODE HERE

if(shouldPrint){
	 par1World.setBlock(par2, par3, par4, number); //This will set the block that has this code in it to oak wood
	}


}

I hope you like it! If this helped you, hit that green arrow in the corner there. If people like this, ill definitely do more!
