How can I use game-maker to detect the force in a collision between two mobile (not fixed) objects?
This is used for damage calculation and possibly compression calculation.
My problem is this: while net force can be calculated using mass and acceleration, the idea of damage is focused on the individual components of the force applied on an object. For instance, if a car is pushing another car against a wall, even though there are no acceleration, people will logically feel like some damage must be done to both cars because forces were conferred on them. I want to know if there is some underlying mechanism in game maker's physics system (I use the latest version) that actually calculate a reaction force from the wall on the car so I can use it to calculate damage.
