Creating content for a racing game means creating race tracks. 

I initially decided on purely procedural race tracks. The endless random track was originally the only track and was purely random generated.  While the random track offers endless gameplay, playing it would eventually feel monotonous. Hence, I added hand crafted race tracks. 

I went with scaletrix track format as there are a lot of available tracks online. However, those tracks were often too long for my 3 minute racing game.

I decided to create my own tracks and coded an editor. 

How the editor works:

• In the layout mode, the track can be configured by adding segments. Moving forward, arc left or right.
• Move along the tracks to modify individual segments
• Segments have variations, like lengths, angles, allowing to creating tighter or wider turns.
• When the starting segment and the last segments are near enough and their angles make it possible, a bezier curve will close the loop.
• In size mode, track widths, barrier distances can be edited.
• Save the track, and choose "custom track" to race on your track.
