Yeh, this is a typical response from you vageta.
Lots of waffle with no substance.
No source code, from you either, no supprise there then, and in fact you admit to using a professionals physics engine, if it's from the david brabham of elite fame i'm thinking of. I did a quick search on the net about this bywire physics engine, but yielded very few relevant links, so i havn't been able to investigate it yet. So infact, you havn't coded car physics by yourself, but have used someone elses algorithm to base yours on. Which i have done also, which just illustrates the need for car physics tutorials on the net and how difficult coding and modelling the physics really is.
Again you embarrass yourslelf, with liitle to no knowledge of what you are talking about.
The use of the term real vectors, is hillarious and i think you are obviously confused somewhere along the line, maybe with polar vectors, interia tensors or cartesian coordinates. ? You talking so much rubbish it's difficult to know where to start.
The vectors in marcos code are calculated seperately. ?
I think what you mean is, that car heading, is calculated using a 2d vector along the x,z plane. Whats wrong with that, it's very common practice to handle heading in this way, and makes perfect sense. A very common technique used in many games and sims for a very long time. ?
Umm, cant stop properly with fixed code.
Well, yes, the physics do break down at very low speeds and stopping, does throw up errors, and this is inherant in the physics code, where numerical instabilities arise at low speeds. The term fixed code, has me a bit mystified and the claim that that is the reason why stopping is in error in the code, again has me a bit baffled.
And why do i have so much trouble calculating gravity. ?
I have no problem with adding gravity to my car physics code, simply calculated with a surface normal, pointing out of the front of the car, and the vertical componants of that normal are scaled by gravity, this causes and downward pull on the car, depending on how much the car is pitched.
There is no problem with gravity in my code. ?, another flase claim by you.
Matrix get height inbstead of polygon collision.
I suppose you mean, why am i using a matrix and not a 3ds or x file landscape. So, what, whats wrong with that. ?
An easily generated landscape with the matrix command, serves the purpose very well, and leaves out a lot of the overheads with an x,3ds object landscape.
By the way, i havn't yest seen decent matrix aligning on a 3ds or x object landscape. Just a point to make.
A matrix does have disadvantages, ie, speed being the main one, but just because i use one does not mean the demo/code is inferior. So i assume, you think that anyone who uses a matrix as a landscape in dark basic, is an inferiror coder to yourself ?
The maths runs in the wrong order. ? What the hell are you talking about. it's marco's algorithm, he can use whatever order he chooses. And in fact it is the standard convention for car physics, so again your wrong in that statement.
Incidentally, i use the same convention.
Unless you can produce a demo or source code to back up your claims, I WILL A CALL YOU A LIAR, FRAUD AND A CHEAT.
I've seen you BULLSHIT for a long time now vegeta and this really just illustrates the point.
I am more than happy with my car physics engine, in it's current state, given the algorithm used. It is in continual development and i never claim that it's perfect. Something you seem to assume it should be. Maybe a better programmer than myself could create even more realistic car physics using the same algorithm.
You seem, to dismiss marcos tutorial and demo's as being poor, and claim that a car physics engine should be created from scratch even though you admit to copying someone elses code.
This is a very difficult task for most people, and marcos site has been a tremendous help to a lot of people in getting them started in coding car physics. It is a basis to start from and build upon.
If you know of another better car physics tutorial on the net, then post the url here for all to see.
I highly reccomend marcos site for his car physics tutorial and code. It isn't perfect, but it's the best youll find on the net, unless you know different.
For one last time vegeta, i'll say, put up or shut.
Show us what you claim to have created.
Note to moderators.
Might be worth locking this thread, if it degenerates to much into a flame war.
