If you get error 0xc000007b on either or both games and know what that is about and how to fix it, please let me know!

Now, if on top of the random track generator they add a freeform road drawing tool like I did, that will become the dream racing game that I imagined.

I never did share that tune I made.

Here's a new video! Sorry for the low fps, it was the best I could do... in-game replays are very quirky with framerate and cpu usage, and they don't work well with video capture software running D: So I rewrote the AI collision avoidance, and it works so much better now. A common problem was that AI cars would wrongfully claim a racing line and crash against the player in an overtaking situation. This happened because the program would go through the race order and set flags to cars, so the AI would only consider itself being overtaken when the passing car was actually ahead by a bumper. The new code uses the same principle (raycasting to check for cars in the surroundings), but makes more sense as it's a direct reaction to what is happening around the AI driver. There are extra checks for cars at the "blind spot", so they are a lot more fair and know when to get out of the player's way. Also managed to make the AI move freely in overtaking situations, the previous code would interpolate a path on the current road section and that wasn't always satisfactory (weird twitching / coming too close and crashing).

Here's a video demonstrating the new track editor, now integrated with the game itself. Not my best creation, but it shows how quickly you can create a course and be driving on it. The editor is mostly mouse-driven, control points can be laid and dragged with button 1 and removed with button 2. The user only handles the track layout and road width. The game then generates the AI racing line and trackside decorations.

Finally made a gameplay video! This is me doing a quick race at Fuji. I wanted to show off the newly-improved AI that uses raycasting to calculate overtaking lines, but the AI cars did some bad moves in this race... I didn't want to do another take as this one was pretty fun, but it definitely still needs some tweaking.

No screenshot today! Here's a sample of 3D audio with Doppler effects.
