Awesome! Thank you so much. I have a few questions about it.
Does overlapping at offset just mean that, in checking that collision, it moves the collision ten pixels down?
Also, with the formula at the end, I don't quite know all that's happening there but I think I get most of it. I'm guessing the 100 in there is the height of the Goomba. I'm not quite sure about the 10 though. Does that correlate to the 10 in the overlapping at offset condition?
Here's that formula for reference: lerp(Self.Y,(Self.Ypos+100),dt*10)
Thanks again!
