Changeset 8423 for code/trunk/src/libraries/core/Game.h

Timestamp:

May 9, 2011, 5:06:49 AM (13 years ago)

Message:

Added and incorporated new class DestructionHelper: instead of doing the destruction of certain singletons implicitly via scoped_ptrs and ScopeGuards, use a method named destroy() that essentially achieves the same, but makes the destruction sequence obvious.
