The idea of that game is the creation of a huge tracks where a lot of sports-cars are competing.
As already posted in this forum, I am creating my own 3D models with my modelers (mainly with Metasequoia EX).
Frankly said the collision system in GameGuru MAX is not easy for that purpose.
In this community there are a few members who have very good skills in mathematics and in trigonometry.
Controlling the Euler's rotation and the collisions of a vehicule with animated wheels is not an easy task.
I still have a lot of work to enhance my scripts.
Last year ( 2021) I started a similar project with another game engine (Java script) and I found it easier to control the 3D motions and rotations but its DirectX version was obsolete.
Currently I spend more time on my racer bike than on this project (it is summertime with unusual too high temperature in my small flat).
