Editor Help

Use F4 to switch bettween the editor and the game. The editor uses a WASD hand
position. Use number keys to change which layer you are editing/selecting. You
can use right mouse to select multiple tiles/objects. You can also hold alt
while selecting to select multiple layers. In tile edit mode you can draw
with the left mouse button. In object edit mode you can move objects and
change their attributes. Cut, copy, paste and undo/redo are all very functional.
When you switch out of edit mode back to the game the player will automatically
be moved to the mouse cursor to make iteration faster.

Engine Controls
Tilde - Brings up the debug console where you can enter debug commands. Try typing "help" for more info. There are a slew of commands, everything from vsync to tweaks for specific gameplay variables.
F1 - Shows debug information like frame rate and engine stats.
F2 - Shows an Box2D debug physics overlay.
F3 - Reloads textures and sounds from disk. This feature has been deprecated since assets are automatically reloaded when they change.
F4 - Toggles edit mode. Edit mode is where a designer can create the terrain and place objects. There is a help bottom in the lower right that will pop up some more info about how to use edit mode. The controls are built around a WASD hand position to mesh with normal game controls.
F5 - Takes a screenshot and saves it to the /snapshots folder.
F6 - Opens up the profiler which uses very precise timers to help track where the frame time is being spent.
