The game is arcade-like, so there are also some big ramps etc.
The car is under the hood just a cube. At the place where the wheels are I just apply for every wheel an impulse to the cube.
But if the car is too fast, it can’t take a ramp, because the cube makes contact with the ramp and becomes too slow to take the ramp (even with friction set to 0).
Sure, I can make the suspension very hard, but this makes the car physic very bad on the road (it drives like a brick in the end)
So my main question is, how can I prevent the cube (chassis) to make contact with the ground? E.g. here in gta it seems the car has a soft suspension, but still it seems there is a hard stop which prevents the contact: https://youtu.be/fRSyh8edxpQ?t=175
But I have absolutely null idea how to implement this
You can place a zero friction collider (capsule) under the front of car. But ideally you should prevent the suspension from allowing the car to touch the ground.
Thanks for your response @zulo3d !
The cube (chassis) has already a friction of 0, but I guess a small invisible frictionless collider beneath the car could be worth a try. At least the area touching the ground would be smaller.
Regarding the suspension, actual that’s the suspension strength I have, if I increase it, it will not touch the ground but the car drives like a brick then.
In the cube’s physics material set the ‘Friction Combine’ to ‘Minimum’. Doing this will prevent the ground’s friction from being combined with the cube’s.
