Added support for one-way collision shapes

README.md

@@ -141,8 +141,9 @@ To setup a collision shape for a tile, first edit the tileset in Tiled:
 
 - Select the tile in the tileset file
 - You should see a side panel "Tile Collision Editor", use the menu above it to create a new shape. Use rectangle or polygon only.
+- For a one-way collision, with the Object shape selected set the `Type` or `Class` field to `one-way`.
 
-For navigation, do the same thing, but with the Object shape selected, set the `Type` field to `navigation`.
