spell and sliding movement

you know how you make "sliding" spell...

i want to make a spell that works like that for a map that i am making. Now im am not noob at triggers and stuff, its just i dont know how to get that working, if someone can give me a hand or just tell me how to go about doing that it would be very appresiated.

If i get one example/bit of help etc. i can work from that and re-create it on the basis.

what i was trying to do, is use carrion sward which slides the caster to the point the caster clicked when he casted the spell.

anyways, thnx for reading

What you need to, is set ur spell....

then in a trigger, im guessing, well i would do this:

Event - unit casts ability
{ i know u know that :P
Con - ur ability

Actions: unit - set speed of ur hero to 200% or something
unit - Move unit instantly to Target of ability beng cast + 20 from offset or something like that ...u get me?
wait 0.2 secs
unit - same again
wait 0.2 secs

u see where this is going, every 0.2 secs make him move + 50 yards towards where he casted the ability from the postion of him to the target.....Sorry i dont have editor open...hope that helped
