I am not sure if this learning aid already exists, but here's my suggestion.
To have a Code Block Wiki that shows actual images of the Stencyl code blocks for specific functions.
I believe this would be an ideal learning aid to those who are Stencylpedia graduates, and now need a way to formulate ideas and see solutions to the most asked for 2D game features. For example:
Player enters an elevator and is transported to next level where he exits. Or maybe he needs to jump onto an ascending balloon, maybe jump down again and interact with a switch that releases a door for enemies to come out...etc etc.
I would personally love this and i'm sure many newbies and intermediate users would too. Now i know many will say, it's up to the game developer to use the logic provided and think for themself. This is fine for those of you who are blessed with program-friendly brain cells. More creative types would welcome it, just as those non-creatives amongst you would welcome a few tutorials on colour theory and how to compose good 2D game characters. I won't say to you 'Hey, you know how to use Pencyl? Now go draw some amazing 2D sprites.'
Any feedback welcome
