An 'elevation' triggered event in SoM?

[dmpdesign]

I am pretty certain any terrain that is greater than a 22.5 degree angle will cause the player to slide, just as a player cannot walk up a hill that is greater than 22.5 degrees...that is if I am calculating correct?

For every 2 meter square the player can only walk up a .5 meter grade (anything higher acts as a wall)... so .5/2 = .25 or 25% grade which I believe is 22.5 degrees (90 degrees/.25).

Again, I am just assuming here, would need to test to be certain. ‎  The slope I have used in DD on a few map pieces (corners specifically on my cliff set) sit at about a 70 degree angle and they slide the player nicely without any hiccups.
