This little platform widget is pretty basic, but should be functional and problem free. It's inspired by the Platform Movement Object, and the method of interacting with it is a bit similar in a way or two. The special "feature" of this platform movement is that the player will automatically slide down slopes that are too steep for the player to walk up.
Some credits to DarkeSoft is probably in order too. When I created a platform engine to help him out solving a problem, I realized that I wanted to attempt to create one myself.
...and yes, I know it doesn't look good. Like my older widget collections, it's only there to provide the functionality
Edit: The people at Gwerdy talked some sense into me, and teaching me about the community's common knowledge about that platform movement objects must be yellow. A 1.0.1 version is now released with this problem fixed.
