Demo Vehicle and any car advice?

Post by EnlightenedOne »

Well I am now well versed in linking demos together to run in Visual Studio 2010 and after many hours I have my demo going (I think I will write a tutorial on it when my project is done) :mrgreen: but this leads me too some questions now I know what is inside the vehicle demo. The Vehicle demo appears to me to be a lighter version of the forklift demo. Are there any real difference between them?

Also if I throw my vehicle around in the vehicle demo with my mouse it seems to go through the floor more frequently than in the forklift demo. What is done to reduce the issue? is it just an increase in the stepping accuracy of the physics pipeline? (sorry for the poor wording) If I put this vehicle onto some bumpy heightmap and drive around at a speed that lets me leave the ground when going over a hill or ramp from what I can tell I have a worryingly high odd of going straight through the floor. Is that just a matter of me modify the physics accuracy when using the mouse to disturb the vehicle? does everyone just increase the collision check speed alot to insure a collision is made with this vehicle class? I guess I should worry more when I come to it. But I am after any suggestions for any improvements available to this class not yet standardised.

I am guessing that these wheels are using a raycast solution to work I have stalked the forum and heard mention of interpolination tricks to improve the accuracy of wheels going over bumpy terrain significantly by this method. Is that implemented as standard at this point or is that something to look into to optimise the appearance of my vehicles?

I mean no offence in terms of stability I know its very flexible and tweakable and in a great deal of respects I am certainly not worthy! but the better experience I can deliver with these cars the better :D plus I am sure anyone who has used this class can offer hints to help insure everything keeps within safe boundaries much beyond what I can guess.

Edit: I modified the mass of the vehicle by alot from 800 down to 10 and my throwing it about was much more stable. I guess you need to keep mass below a certain threshold even when comparing it against an object with no mass to ensure it doesn't go through. If I modify the relative acceleration and the tire friction I should be able to scale things down although I am certainly still just playing around :)
