 Traditionally in an entity system, you may have said I want to be able to fade out my entity by doing a simple **Entity::FadeOut(int fadeTimeMS);** Or possibly a more fancy **Entity::FadeOut(int fadeTimeMS, int delayBeforeStartingFadeMS);** Traditionally in an entity system, you may have said I want to be able to fade out my entity by doing a simple **Entity::FadeOut(int fadeTimeMS);** Or possibly a more fancy **Entity::FadeOut(int fadeTimeMS, int delayBeforeStartingFadeMS);**

-The delayBeforeActionMS parm is self explanatory, it's useful to schedule things to happen in advance at specific times.  So you can play a sound effect, fade out, and then kill the entity step by step instead of all at once.+The **delayBeforeActionMS** parm is self explanatory, it's useful to schedule things to happen in advance at specific times.  So you can play a sound effect, fade out, and then kill the entity step by step instead of all at once.
