Console -- A love2D console.
Posted: Sat Jun 04, 2011 11:58 pm
I don't know why this was never done!
This console is a Lua console. When on, it gives all input to the console.
Functions:
Console Console:Init()
Place this at the bottom of your code. Reason for it needing to be at the bottom is because it overwrites some Love2D functions. You can run any other command anywhere else in your code, though.
Console Console:SetEnabled(true/false) (or :Enable() Disable())
The console is disabled by default. This will either enable/disable it.
Console Console:SetOpen(true/false) (or :Open() Close() Toggle())
Sets visibility of the console.
boolean Console:IsOpen()
Returns whether or not the console is open.
Console Console:WriteLine(text[, r,g,b])
Writes text to the console. Note that this doesn't wrap. By default, the color is white.
Console print(text)
Writes white text to the console.

If anyone uses this, please tell me. I want to see how its used.
