only targets heros

i have a trigger like this it targets heros first and does actions then jumps to another hero then does more actions

im having trouble with the second hero it hits

Jump
Events
- unit casts abilitiy
Conditions
- Abilitiy = Jump
Actions
- Move caster to (target)
- Damages (target)selected hero

(OK THIS IS THE PROBLEM THIS IS THE SECOND PART OF THE TRIGGER)

If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
- There is a hero within 900 range of(target)
Then - Actions
- Set that hero = (newtarget)
- Move caster to (newtarget)
- Damage closest hero(newtarget) with 900 range fo X amount of damage
Else - Actions

I'd love any help thx :)

Eh.. there is no "There is a hero within 900 range of (target)"

It would help if you just put the trigger as it is shown on your world editor

What you need to do is Pick every unit in units around the target within X range, matching unit type of picked unit is a hero equal to true, set it on a variable and do your actions.

You just posted what you would like to do. Please post the trigger.

ok here is what i have of the trigger so far this works fine

it deals the damage based of distance between the casting hero and the targeted hero (distancex0.35)

now i want it to be able to jump to a second target (ONLY HERO) and deal the same equation (distance between 1st target/caster and 2nd target [caster is now on top of 1st target by the way])

the move instantly to point has nothing to do with the probly ill smooth it later to make it quicker moved.

Flash Attack
Events
Unit - A unit Begins casting an ability
Conditions
(Ability being cast) Equal to Flash Attack
Actions
Set zCaster = (Casting unit)
Set zTarget = (Targeted unit)
Set zCasterPoint = (Position of (Casting unit))
Set zTargetPoint = (Position of (Targeted unit))
Set zDistance = (Distance between zCasterPoint and zTargetPoint)
Set zAngle = (Angle from zCasterPoint to zTargetPoint)
Unit - Turn collision for zCaster Off
Special Effect - Create a special effect attached to the overhead of zCaster using Abilities\Spells\Human\Slow\SlowCaster.mdl
Wait 0.20 seconds
Unit - Move zCaster instantly to (zCasterPoint offset by (zDistance / 3.00) towards zAngle degrees), facing zTargetPoint
Wait 0.20 seconds
Unit - Move zCaster instantly to (zCasterPoint offset by (zDistance / 3.00) towards zAngle degrees), facing zTargetPoint
Wait 0.20 seconds
Unit - Move zCaster instantly to (zCasterPoint offset by (zDistance / 3.00) towards zAngle degrees), facing zTargetPoint
Special Effect - Destroy (Last created special effect)
Special Effect - Create a special effect at zTargetPoint using Abilities\Spells\Items\AIvi\AIviTarget.mdl
Set zDummyDamageTarget = (zDistance x 0.35)
Unit - Cause zCaster to damage zTarget, dealing zDummyDamageTarget damage of attack type Normal and damage type Normal


This is where i want it to say
if there is a unit equal to hero true
within 900 range of 1st target/caster
deal damage to that 2nd target(hero) based on distance between 1st hero/caster and 2nd hero(target2)


If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
Then - Actions
Else - Actions

As stated by Vile already, you will need to set a unitgroup in range of your casting units location at that point in your trigger. Just use conditions in the group to get the unit you want.

I would also change CastingUnit to TriggerUnit as to avoid problems if you get longer waits in the trigger.

If you still have trouble, let me know and I may be able to type it for you.
