Just multiple instances of a sprite named "Path" that I place on the track. Bullet behavior for "car"
And a rotational movement to the angle of the next sprite.
6 minutes of work and 3 events
It is possible to improve it by putting two or three conditions and adding instance variable to the "car"
You can also use the pathfinding plugin but it increases CPU usage... depends of what you want and number of objects/solid...
Yes, I'll share the capx asap
