Ledge Grab and Traversal Gameplay

[yahadi]

Can someone point toward how to implement an edge grab and traversal gameplay where you can jump and grab a ledge and hang to it, at which point you can move left or right.

I have seen this system in a couple of Unreal engine games but I am not sure if it is implemented with source code, kismet or unreal script.

Project Stealth uses traces for free-roaming (climbing stuff, or mounting rails etc). It's based on the normals of the materials. It's made in UScript.

It can be implemented all Unrealscript, Kismet and C++, but in the case of the UDK, it's probably going to be best to implement this in Unrealscript. The way I would probably do a system like this, is to use player state changes which define exactly what the player can and can't do when in different states. A kismet system could work, but it is a lot of extra work on the level designer.
