From the code, I don't really know how to make the objects (Trees, roads, clouds) go to x = 400 and move across the screen when these objects go off the screen beyond x = 0 so that the animation will be continuous forever.
Ps. I use the variable called "movex" for all of the objects that I want them to move.
Ps.2 I use Khan academy website to do this.
Thank you!! :)

Here is the image of my work!!
First off, your question and given code was confusing. In your code, you put movex as the location of the x values for your shapes. Instead, you should use your defined but not used variable x . So in my answer instead of movex as the position of the x values of the shapes I will use x , and I will assume that movex is actually the number you want to increase x value by.
A simple, easy, one-line way to do this is to just add this:
x += movex;
This will continuosly increase the x location of the shapes by movex each loop.
Also, since you're inly using this to draw, I would suggest usng
translate(x, y);
That way, you can just type in the number and not have to aa x and y to it each time.
