//Coding is actually very hard and a lot of help was given by other students 
//Major credit goes to ZACHARY MACLEOD for explaining a majority of the code used in this assignment 

//1. Every time draw() is executed, so every frame, the program generates a random number from 0 to whatever number you want.
//2. This random number (which is stored in a variable) is checked to see if it is above/below the halfway mark between 0 and the number you picked as the maximum.
//3. If it is above, reverse the direction of the milk carton. This also works for below, you choose whichever.
//4. There is a chance that the milk carton will hit the sides of the screen, so you'll have to check the carton's position and reverse regardless of the number generated that frame if this occurs.
//random(min, max);

//Basically you want 2 states 
//One the adds x, and one that subtracts x
//that can labeled
//int direction = 0
//0 being left
//1 being right
//And you need something that switches the states randomly
//But it depends on how often you want it to switch
//Cus using just random(min,max) is going to make just freak out and spazz out
//Than you just constrain x to 0 and 400 and your good
