Hey, watching SSBMStuff's run in any% and he does the wall glide around the front of the mountain to get into theatre.
Are there any tutorials of this? I haven't been able to work out how to do it.
The trick he actually does is a sproderman, not a wall glide. Basically what you want to do is repeated double jump inputs (x then square) around the wall, at a similar angle to the angle you'd be at to wall glide (although you can get away with facing a bit more towards the wall than you can with a wall glide).
To get onto the wall to set this up, I do a walking double jump from the standard spot, glide and then hold down left. It might take a while to get the timing down for both of these days things.
I might create a small tutorial for this when I get home, through the week, but hopefully this helps you out for now
