Called directly after setup(), the draw() function continuously executes the lines of code contained inside its block until the program is stopped or noLoop() is called. draw() is called automatically and should never be called explicitly.

To create your own function, you need to do four things: Write the return type of the function. Write the name of the function. Inside parenthesis (), list any parameters the function takes. Inside curly brackets {}, write the code that will run whenever the function is called. This is called the body of the function.

There can only be one draw() function for each sketch, and draw() must exist if you want the code to run continuously, or to process events such as mousePressed().
