The Spaces of the upper strips at the Border is less than the Lower ones, for this: Sin((((120-f%)/40)^3)+dist%) f% is the y position of the Line and Dist% is just a Framecounter to simulate driving. calculates a point in a Sinewave at which frequency increases starting with the Phase dist% I use this to deside to use Color 7 (White) or Color 4 (Red) for the Border bc%=col%(7-3*((Sin((((120-f%)/40)^3)+dist%))>0)) the color value is 7 but subtracts 3 if the Result of the Sine-Function is Positiv. Look at the Listing in the first Post. It is the Function get_BorderCol%() from the Listing above in a conpressed form. Cause every function call takes some time and it is called 120 times per Frame, so I put it in one basic Line. The Idea for this method is from javidx9 (one Lone Coder) who used the same calculation in his video. Code-It-Yourself!
