I have a top down 2d game that uses a physics engine (Farseer).
I'm using the standard steering behaviors to make the AI move around but I'm not sure the correct way to take the so called "steering force" calculated by the steering behavior and apply it to the physics bodies.
The steering behavior SEEK returns
return desiredVelocity - currentVelocity;
So it is returning a difference of two velocities (in meters per second).
I need to convert this into the force (in Newtons) that I need to apply to my physics body, taking into account its mass and acceleration etc.
I know it should be simply but I'm getting confused! :)
