After tearing my hair out attempting the platforming strat for Goliath, I finally switched over to the cube jump method. With some practice I believe I've found a reasonably consistent setup to make this jump work.

1. The usual setup - jam the barrier and lock FPS to 60.

2. Plant the cube roughly parallel to the barrier. http://images.akamai.steamusercontent.com/ugc/357275885707447815/903509DDA5F43308692DD862EDF73CA261EF6EF9/

It should be right on the left edge of the barrier generator. http://images.akamai.steamusercontent.com/ugc/357275885707448069/5114B77741DA1A7780CF58A777CE18A72014ECDB/

3. Look for this particular spot of grass/dirt/whatever and stand on it. http://images.akamai.steamusercontent.com/ugc/357275885707448291/6B75FDF86485AAD8FA637761F88F82DD6169A9D7/

Another view with both the cube and the spot visible. http://images.akamai.steamusercontent.com/ugc/357275885707448446/7D9D32E467320A96D226038CE5B7F7D3696CFA4E/

4. Perform cube jump as usual. If you didn't know, click the cube (or whatever you have bound to interact) and hold down jump. You should land in the vicinity of this wall - this is still a bit inconsistent, I've overshot the wall a couple of times but generally I either land directly on or short of the wall, in the switch area. http://images.akamai.steamusercontent.com/ugc/357275885707448590/B87CA907E1E5BA0818AA08767F60D5B64B7A3E6C/

5. Jump off the right side (facing forward) of the wall if you landed on it. Hit the switch.

Can anyone else verify that this setup works? Maybe something more precise?
