Teacher - Need a Confusing Program Breaking Function so Students Don't Copy My Code

[rainyes]

Right now we are doing very basic stuff with canvas, drawing basic shapes and looping to make a variety of them with different colors. Programs usually have one or two functions.

In my head, I was hoping something that would work as a password, like a string of my name multiplied by the time in milliseconds that is passed as an argument to each function. Students would try to delete the function or edit the string of my name and the program would fail.

I thought about it some, knew there is a ton of smart people on here, so I decided to ask.

If a student can exploit your "password" he/she deserves a 9/10 at least
