I can't work out how to make the newton demo act more real. Aka real vehicles have faster acceleration and speed. also when u reverse you don't wait for ages until it slows down, it nearly instantly stops then reverses.

Iv looked at the C demo that comes with Newton SDK(which acts realisticaly) and can't seem to find anything in it that would make the NewtonVehicle demo act more real. Increasing traction seem to make the wheels revolve faster but they don't seem to have any grip, so thats all it seems to do. Increasing the mass makes it go slower and decreasing u get very wierd physics results.

Anyone know how to make the Vehicle in the NewtonVehicle demo go faster? (i.e so that it could jump from one ramp to another..... not drive off the end at 0.000001 mph)

change the value of newtonupdate to a higher value .... this should always help.

Shouldn't have to speed up the entire world just to make a car go faster......

then adjust the force/torque attented to the car ...

To make the car go any distance with Torq u need it to be around 25000 and the wheels spin like mad.

the only thing that i can find that has anything to do with force is here:



and thats just so it has gravity.

Iv played with basicaly every value, nothing seems to give any good results.

now i tried it myself

if you set the torque in the procedure

but dont turn it into an to high value, i tried it with 2500 and 5000. i think 10000 is also possible but 25000 ???? well this looks tooo much ....

5000 causes alot of spin, and isn't much different to 2500.

Tires never grip.

Attached is a Demo Engine im working on.(easyer to see the difference with torq's) The only way i found to increase speed (a bit) was to change the friction of the MatVehicle to 2.

Keys:
Arrow keys - Movement
Enter/Return - Flip
Space - Brake

Extract Both Zips to a directory (it came to 288kb when it was all in one... evil forum size limit). Newton dll 1.3 isn't included.

Note: the boxes at the end of one jump don't work... the collision areas for them fall through the floor taking one of the boxes with them... but not the rest...
Note2: when the wheels spin they look like there going back and forward at the same time (if u turn on the show collisions from the menu), and when there not spinning they look like there going one way.

Use NewtonVehicleSetTireMaxLongitudinalSlideSpeed to change the point at when the tires loose grip and do a burn-out. The fact that there is no high friction in that demo is because that value is low (or set to default) which means that the wheels start to slip at low speed and when wheels are slipping (like in a burn-out) the don't have any grip and therefore it seems like low grip.

yeh i found that in the C++ one and added it. So in theory if the torq was increased gradualy insted of being a set value, it would work properly? If so how can i get the value of the current torq(i havn't seen a function to get the current torq)?

You don't need to know the torque, since there is no such property for a wheel (you put torque on a wheel which causes a force). What you need is the angular velocity also known as omega which can be retrieved by NewtonVehicleGetTireOmega.

So to work out how much torque u need to apply to the wheel would u do



Where 1*MuliSize is the radius of the wheel. And then add the Speed + say 50 to the wheel as torque?
