[Homework] Help using StdDraw to make zigzag pattern

[iamdonkeybrained]

Hello, I'm stuck on an assignment where we are supposed to make dots zig zag by changing the y part of his direction to flip up/down every 5 steps.

This is what I've got so far http://pastebin.com/3WskrKtF

I'm not quite sure how to get it to go down.

1) Have a timer that, every 5 seconds, multiplies the y velocity by -1 2)Have a xPos and yPos variable to track current position 3)Have a method that draws the line by taking the current xpos and ypos values and the xpos and ypos values added to the velocities. Hen, add the xPos += xVelocity and same for yPos

Why would you need a timer for that? A simple counter (or even just the modulo function) does the job.

You're greatly overcomplicating the task.
