i think he is not talking about the trigger...
for your ability, set the
-
(Ability being cast) Equal to Teleportation (Unknown)
into an ability that target point, e.g Carrion Swarm, Shockwave, or Summon Ward etc.
or if you have already created a custom ability.
like:
-
(Ability being cast) Equal to Shockwave
and then, don't forget to add the ability to your Hero.
make sure the ability in the trigger match with the one you add to the Hero.
after that try it ingame.
and to those people above,
the event "Starts the effect of an ability" is already perfect for what he attempt to achieve (for now).
other event like "Finishes casting an ability" will fire when the unit has "Starts the effect of an ability" + finishes it cast animation.
"Begin casting an ability" will fire when the ability is going to be casted, before cooldown and manacost is applied, and it can be abused if used improperly.
so "Starts the effect of an ability" is the best option for what he attempt now.
and:
@defskull: a delayed effect =/= channeling spell.
