Hey guys, I’m making a program where horizontal lines spawn at the edge of the screen at regular intervals, as if it were a moving road. What are the coordinates for 1/3 and 2/3 of the way down the screen on the right side?

X is the width of the world, Y is the height of the world multiplied by 1/3 or 2/3.

x and y are coordinates -- not distances. width and height are dimensions of the world. 
int hiY = getHeight()/3;
int loY = getHeight()*2/3;

Well, I meant that the X-coordinate where the object will be added equals the width of the world. Similar for how I described the Y-coordinate. Didn't think one could get confused by my formulation given the fact that it fits the question pretty well.

I agree that your response fit the question. I just felt clarity was important. Some of those new to greenfoot take a while to get things (if at all). Not saying this is one of them.
