Hi all. Thought i'd post this as there has been a lot of questions about platform stuff recently.http://dl.dropbox.com/u/1646976/PLATFORMENGINE.cap
Has loads of features ducking, wall slide, wall jumps, super jumps and some more. I created it a while ago so the event sheet is messy, there are probably redundant events or actions or easier ways to do things - but it works quite well.
It's commented in as plain English as I can (explaining stuff isn't a strength of mine) and is aimed at someone totally new to Construct.
There are some bugs - for example crawling under a low wall and letting go of the duck button "shoots" you from beneath the wall, I have fixed this but can't find the cap at the moment.
You can see it in action here - http://www.youtube.com/watch?v=_LDLKVa3O9k
Any problems let me know or if you have any suggestions or improvements.
