===Delayed Effects===
In composite effects, it is often desirable to start a certain effect only after a certian amount of time has passed; for example, we might want to fade in a circle and only then suddenly flash a pentagram in its centre. This could be accomplished by an `on-death' emitter that is spawned when its parent particle dies.
:''Death effects would also be useful for a lot of other purposes like magic projectiles which explode on impact. I would suggest to implement this in the xml files as an attribute "activate-at" for emitters. Possible values are "immediately" (current behavior), "death" or a number of frames.'' --[[User:Crush|Crush]] 18:51, 22 June 2008 (CEST)
