Spell using arrow autocast

[Tinker]

How can i make an arrow autocast for a melee hero that when it is activated the hero has to chain lightning to the attacked unit???

you need to use a dummy unit and a damage detection system, then do this:

• Chain Lightning on Attack
  • Events
    • Game - GDD_Event becomes equal to 0.00
  • Conditions
    • GDD_DamagedUnit has (your auto-cast arrow buff) is True (boolean comparison)
  • Actions
    • Set Temp_Point = Position of GDD_DamageSource
    • Unit - Create 1 (Dummy unit) at Temp_Point facing (Facing angle of GDD_DamageSource
    • Unit - Add chain lightning to (Last Created unit)
    • Unit - Create a 2 second expiration timer for (Last Created unit)
    • Unit - Order (Last Created unit) to chain lightning GDD_DamagedUnit
    • Custom Script: call RemoveLocation(udg_Temp_Point)

click the link i posted please
it gives an explanation for each of those variables
GDD_ is the prefix for the Gui Friendly Damage Detection system that i linked to
GDD_Event is a real variable that the system uses, when it becomes 0 a unit took damage
GDD_DamagedUnit is the unit that took damage
GDD_DamageSource is the unit that dealt the damage
