I've been customizing Tim Moore's Asteroids game off Koolexchange. I wanted to add a fourth flying virus (asteroid originally) that originates south and travels north.
My issue is making it travel in that direction. I can usually figure out what element in the existing code I need to change to make it do what I want. I've been tearing my hair out with this one though.
I can place it's starting point where I want it at "this._y = 500;" but I can't seem to find where in the code it tells these asteroids the direction to travel? I started by copying "bolder3", pasting it and tried changing the code.
No matter what numbers or symbols I tried changing the fourth, purple virus continues to travel in a north to south direction.
Can someone show me where the virus' direction of travel is in the code?
