If I create a Area node and enable gravity_point, then what does the value in gravity represent? It says the value can be -1024 to 1024. What exactly is that value? Is it the acceleration due to gravity? If so, what equation does the engine use to create acceleration due to gravity at a particular distance from that gravity point, because it will be different at different distances.
