Creating Behaviors Composing Wakeup Criterion

Wakeup conditions can be complex and changing, for example:

In a game, the user must press two buttons within a time limit to open a door

Behavior's initial wakeup conditions are:

Viewer near button 1 or viewer near button 2

After button 1 is pressed, conditions become:

Viewer near button 2 or time elapsed

If time elapses, conditions revert back to the initial one

If button 2 is pressed in time, behavior sends event to wakeup door-opening behavior, then exits without rescheduling
