Vehicle Damage to Punches

[SantiagoGC34]

Hello community! I am developing a Roleplay server and when trying to add a function to the vehicles.lua script so that the vehicles are not damaged if they are hit with fists or kicks, but only damaged if a weapon is used or when colliding with the car itself.
How can I do it? I have already tried 100 types of events and functions and the vehicle parts continue to be damaged. Any kind of help? 

Thank you very much in advance
