Animating changes

I have an animated character which swings a sword around.
It works ok ,but when the camera gets within 5 points of the character ( using EntityDistance) I want the sequence to change from swinging the sword to falling down. I am using extractAnimSeq for the sword swinging sequence.Any advice?

Do you mean 5 units?

Don't you just use the Animate command to call up the other sequence?

Animate entity[,mode][,speed#][,sequence][,transition#]
