In this simple example, I use 3D X (width of bridge), Y (height of pylons) and Z (an offset counter for movement) to calculate screen X and Y using a View Factor (VF). The height of the pylons varies using the Sine function. The height of pylons is calculated once per draw cycle, and the results of these calculations are stored in lists to also draw the ropes and cross beams of the bridge, to avoid calculating these again, or unnecessary Pen up/down. The "road" is simply a sprite with no code. All code by me (@kriblo). Study the code inside. Thank you @Constellations- for your inspirational project Golden Gate Bridge: https://scratch.mit.edu/projects/384797257/ Music is Ukulele from Bensound. The backdrop is a stock photo from the world wide web.
