A-chassis colliding so hard and rotating

  1. What do you want to achieve?

I want to decrease or remove completely the car bouciness/elasticity when colliding in a higher speed

  1. What is the issue?

The car is hitting so hard when colliding in a wall for example

  1. What solutions have you tried so far?

I tried to find in Devforum or any help in Google but i didnt find a thing. I already tried to change all parts CustomProperties (Elasticity to 0) but it still doesn’t work.

Have you also changed the ElasticityWeight to 100 so it takes more priority?

If that doesn’t work, you can also try writing a script where if there is a sudden negative change in velocity, and a ray casted in front of the car detects a part, it could reset the rotational velocity of the car.

ElasticityWeight doesn’t work

For your second solution,

local RS = game:GetService(“RunService”)

local car = script.Parent
local PrimaryPart = car:WaitForChild(“PrimaryPart”)
local lastVelocity = PrimaryPart.Velocity

RS.Heartbeat:Connect(function()
local newVelocity = PrimaryPart.Velocity

if (newVelocity-lastVelocity).Magnitude < 0 then
	
end

end)

would I change “0” to a lower value? And also, do I need to check the magnitude sudden negative change inside raycasting or raycasting inside this heartbeat?

I made this, but it looks like doesn’t work properly fine and good like i’m trying to make it

local RS = game:GetService(“RunService”)

local car = script.Parent
local PrimaryPart = car:WaitForChild(“PrimaryInstance”)
local raycastDistance = 15
local lastVelocity = Vector3.new(0, 0, 0)

local rayparams = RaycastParams.new()
rayparams.FilterType = Enum.RaycastFilterType.Exclude
rayparams.FilterDescendantsInstances = {car}
rayparams.RespectCanCollide = true

local function detectCollision()
local raycastResult = workspace:Raycast(PrimaryPart.Position, PrimaryPart.CFrame.LookVector * raycastDistance, rayparams)
return raycastResult
end

local function checkCollision()
local currentVelocity = PrimaryPart.Velocity

print(“Doing”)

if currentVelocity.Magnitude < lastVelocity.Magnitude * 0.8 then
local collision = detectCollision()

  if collision then
  	PrimaryPart.RotVelocity = Vector3.new(0, 0, 0)
  	print("Collision detected!")
  end

end

lastVelocity = currentVelocity
end

RS.Heartbeat:Connect(function()
checkCollision()
end)

#5

I used:

for i = 1, 2 do
if PrimaryPart.RotVelocity ~= Vector3.new(0,0,0) then
PrimaryPart.RotVelocity = Vector3.new(0, 0, 0)
print(“Velocity changed”)
end
task.wait(1)
end

And work a little bit better, but it’s still bad for me. It’s changing the velocity too late.

Maybe you can increase the friction of the tires? It may depend if you want your vehicle to be floaty or not.

#8

Do you mean change it in _WHEELTUNE? Or is there another place to change it in A-Chassis?

#9

I noticed that even though i’m on lower speeds if I collide in a wall it rotates too

#10

Could you send a download of the car you are using? I can see about experimenting with the car.

I couldn’t find any solution sadly. I hope you do manage to figure it out eventually though.

Yes, that’s sad. Thank you for helping anyways!
