Many people asked me about the Physic Car tutorial and I must say I'm writing now, but I have little time, so be patient.
In the meantime I've made a kind of tool for a physic car setup, It has sliders for more interesting parameters in two sections:
Car section to the left with sliders for suspension, tyre stiffness, power engine, etc.
AI section to the right with thrust and driving sensitivity.
Also there are three cameras, a classic follow camera (by default), an on board camera and an interactive camera. When you select this last one, the offset parameters appear under the AI section.
I think this is a good way to know how different parameters affect car behavior. Please try carefully at first and look for reactions.
You can drive and leave the track pressing "i" to test in an off-road fashion.
The values exposed next to the sliders are real world values, it means you can use what you see in your code.
The final tutorial will have explanations on those parameters but will not include the interactive part (sliders) nor the AI, just the basic script where you can tweak the values.
The car model is a De Lorean I found for free in Turbosquid, if anyone knows any problem with that please tell me and I'll change.
The car is at real scale 4,2 metter long.
The track is based in the Infineon Raceway.
"c" change camera
"i" AI on/off
"r" return to the track
Please tell me if you find this interesting to continue improving.
Thank you and enjoy.
