I made a program of interactive traffic lights, basically there is an intersection between two roads and there are 4 traffic lights and 4 cars, one of them going from right to left, another from left to right, another from top to bottom, and another from bottom to top. I have already programmed the functions but when I run the program in the first seconds everything looks fine but then I notice that the cars that are going from top to bottom and bottom to top are moving forward in relation to the X-axis for some reason that I can't explain. I will leave images for you to understand. After seeing this happen I thought that it is probably the way I am moving the objects around but I am not sure. I know the code doesn't follow the conventions but my teacher asked for it this way. I'm sorry because I think this should be basic but I started processing a few days ago and I have been searching and seeing other posts and it didn't help at all...
