Platformer Collision AS2

[RemminyCricket]

I was wondering if anybody could point me towards some really good platformer collision tutorials. I've been going through AS:Main and many other tutorials for the past few months.

I want to try and make a platformer. Nothing fancy, just jump from point A to B. However it seems that I always run into collision problems with every tutorial I read.

I was wondering what method of collision I should use to avoid the following:

Bumping Slightly into walls
Floating or colliding when there is still room in between my MC and the object
Falling Through Floors
Clipping and Falling through corner

thanks for any help in advance!

Well platformers aren't that hard, it is just you measure them.

its easy..

onClipEvent(enterFrame){
If(platformzorz == truez){
(graivty+collision+ground+items+othercoo lthings = true)
trace("yey its workin!");
}
}

that should work.. YEY
