2D simulation game using exlusively Lagrangian equations of motion. It's a 2D motocross game similar to X-Moto, ActionSupercross and such. Some stability issues persist but mostly it's good already. I shall compile it soon for Windows: one of the problems is that Windows compilers must periodically be reinstalled, and that's annoying.
Using Lagrangians in games is not a well documented thing, but it allows to achieve exellent results in very little time, soon after a good parametrization of a given physical system was found. The problem is collisions... they are more problematic to do. The near-end of this little game is to get started with using Lagrangians in games; the far-end is to provide groung for creating a 3D rally game using Lagrange equations of motion, one that fixes certain shortcomings of the CTruck3D _Open .
Ah very much thank to the Maxima project !! Without that program the calculations would have been impossible to do!
Features
- I adopted a new method. The dynamics of free vehicle is simulated with a 5-DOF Lagrangian system. Then, if car tries to penetrate ground, a collision come into play to prevent it. As if it were a single ridig body. And a stabilisation spring is also there to keep it as close as possible to the surface of ground (if it's resting or rolling).
- Some stabilility issues there are, but i will try to fix them: all simulators in which there are collisions or springs *have* stability issues... the question is to avoid critical situations, so....
- I posted also a project (search it in my space) where there are other simulations with lagrangian method, also numeric-only approaches.
- soon i will do another version which does all this simulation with only numerica derivatives... so that one can also deifine personalised motorcycles, recompile and play.
