Alright so I'm trying to make vehicles more deadly. When a player or bot get hit by a vehicle I don't want the vehicle to bounce away but the player to fall 100% of the times (just by a simple touch) and then in some realistic sense loose health depending on the collision force. What function would you recommend? Are any of these properties useful for my needs? I'm thinking of collisionDamageMultiplier and onVehicleCollission for instance, would those be a good approach? have anyone done anything like this before?
