Jumping Help

I've never understood how to get 'Key input Processing' working. --- Jumping in an RPG game might be pointless, but it does add a bit of the Platform style. And, if it's pulled off without a hitch (after days of the programmer swearing at the computer to make it work), with other superfluous little extras, then the game could go down as one of the best on the internet.

Days, more like weeks if you're not careful. A line of trees, like this:



Looks impassable, but you can actually "jump" through the trees. This is because there's only one line of spaces that are actually blocking the hero (same layer as hero), so when jumping, the hero skips the bottom part of the tree and lands "behind" it, underneath the canopy. Which is something you don't want, obviously, and can lead to players skipping major parts of the story and getting places they should not be, or taking major shortcuts through a forest, for example.
