You'll find a light-weight, greatly optimized Ingame-Console which is awesomely is easy to use.
Features:
*Plug & Play, just set the static Visible Property to true or attach the shipped "OpenConsole" script and you're ready to go!
*Add Commands by using Attributes! No need to define extra functionality, use the same functions you are using for your game logic! (Parameter values and their default values will be automatically set up)
*Nearly no memory needed until your first call, and no runtime-overhead if the console is closed!
*Use the Console to print out your unity debug log messages ingame, by forwarding them!
*Use the custom window handling to add special functions like an Item Picker, FPS windows, Color Picker and more (Two Examples included)
*See Suggestions for your input as you type them!
*Auto-Complete your Commands by pressing "TAB"
*You can use the command history by pressing the "Up" and "Down" Button to switch between last typed commands.
*Is the Output-Log to much for you? Press the Console Hotkey once more and switch to an even more lightweight Version!
*Many Example Commands
Example:
(Note that you'll have to press enter two times, because of how the webplayer handles input!)
