i want the part to brake or fall apart when crashed into with a car
Connect the BasePart.Touched event to BasePart:BreakJoints(), and make sure the part that touches the car is not part of the car.
This script should be put in your car. Any part named Wheel will not fall off.
local car = script.Parent for _ , part in pairs(car:GetDescendants()) do if part:IsA(“BasePart”) and part.Name ~= “Wheel” then part.Touched:Connect(function(hit) if not hit:IsDescendantOf(car) then part:BreakJoints() end end) end end
