Objects Interactions

[maikson88]

In the video is said how difficult and clunky can be to implement springs when we deal with velocity directly, but what is the recommended way of doing this on the method provided using only forces?

I created an interface to interact with springs and any other object when colliding, adding a new force this new force uses the same code you used for jump and movement, but I would like to know what are your implementations, how about a new video about "interactors"?
