I understand what he wants but have no idea how to do it myself, I've just decided to just let the player "jump" since in my game it's in smaller increments(20px I think) so it doesn't look to weird.
Anyway, what he wants Dom, imagine every FPS you've ever played for example, in those games when you see an object(lets take a human for this example) move from point A to point B, you see him walking/runing there, right? And this transition from point A to B while playing a walk animation can be a smooth and as slow as the dev wants, pixel by pixel. What happens to him is the animation plays in point A and then the object just dissapears from A and appears in B. Like in Flappy Bird for example.
Hope I'm explaining it better.
I think the "How to make a platformer" tutorial could help you Arlys if you're trying to make a walking/runing transition, but for other objects/movements I have no idea mate, sorry.
