Hi there,  
I have been learning to do a platform game looking at Kirupa’s tutorials, I got to do bottom and left and right sides collision detection working almost good, but I have these problems:

- the bottom collision doesn’t work well, usually when you fall of a platform, the character is used to keep some pixels above the ground;
- I’m having problems to make a ceiling collision, the player gets stuck bellow the ceiling;
- I have tried a lot to make a vertical scrolling, but the scroller aways doesn’t stand at the correct Y position;
- How can I do slopes on this engine?

There are the engines, one(newer) has the try of ceiling collision and the other(older) has the vertical scrolling try:  
The newer(in Flash 8):  
The older(in Flash MX 2004):
