Realistic 2D air friction in unity
I want to make an evolution games similar to this old games that was generating cars.
Except I want it to be more realistic.
So I want air friction to impact the speed of my cars, but how do I do ...

2D platformer:How to avoid "bouncing descend" when walking down slopes?
I've been working on implementing slope collision by SAT(Separating Axis Theorem). And then I have a trouble. When my character walks down slope, it moves like a bouncing ball:
The slope has 3 ...
