User:Pedersen/Code Samples/Graphical Debugger

The following class is what I presently (9/12/2007) use to manage my drawing routines. During the normal run of my code, any class can add a line, square, or circle to the "to-do" list, specifying how long the graphics should last. Turn scope is for anything constantly updated (e.g. waves, wall intercept position). Round scope records events that last longer (e.g. where bullets have hit, tank travel paths). Battle scope is also available for the long haul.

Enjoy. -- Martin
