Changeset 2406 for code/branches/objecthierarchy2/src/orxonox/tools/ParticleInterface.h

Message:

Added TimeFactorListener to properly handle changes of the global time factor (makes the game faster or slower). Currently supported in Backlight, ParticleInterface and Timer, which were all critical classes I could think of (all other classes are already covered by the adjustment of dt in tick(dt)). It seems to work well, both with small values (0.1, 0.01) and great values (10, 100). Even pausing the game (0) works fine.
