[Trigger] Trying to make a projectile spell.

[Druu]

Here's the deal, I want my fireball to explode when it "hits" the location I set
when I began to cast the spell. I tried many ways before coming here. I think
its either I made a mistake somewhere or it cannot be made that way. I don't
really know so I'm asking people here to check it out and see what can be
done or if this is off the limit GUI can do.

Thanks.

GUI can pretty much do anything jass can except maybe not as efficiently and leak free

Ok first off i just took a real fast look and it seems its not a target unit spell? so using points in that way i assume you wanted it to be a aoe spell perhaps? then why do you have the dummy unit heat seeking the target point?
Also if this is not what you were intending to do and you did want it to be a unit targeted ability such as storm bolt then you need to change your tp var's

And for the Event on FireballDamage i think you may have not assigned conditions right.
((Target unit of ability being cast) instead of triggering unit might be what you want for both the event and the condition, also that will make sure its an enemy also depending on the spells allowed targets.

get some of those kinks out and let me know where your at after that, or if i am assuming wrong let me know more of what you want it to do

Edit: nvm he posted a sec before me, go ahead and try that out first if you want lol

 

[Druu]

what Mortar posted is a insta-cast.

if you check my triggers, it has a 2.3 seconds cast.

So I want is to cast for 2.5 seconds then create a fireball at the caster location
going toward the designed location [where the dummy unit is at] then when it
comes within range of it, explode and deal the damage.

Edit: I found some mistakes already, correcting them in the first post.

Nope, you can not use an ability type as a key to a hashtable which you can do in JASS.

Also the event only runs when the effect of the ability starts, which basially means after casting delays when it begins to channel (if ability supports that) and before cooldown is started (interupting ability will cause cooldown not to start).

 

[Duhcake]

Just create an 2.5 second timer, and trigger which has event of the timer finishing.

 

[Druu]

Actually, the spell works wonder until it comes to the explosion. I think the
non-working trigger is the fireballdamage, but I can't get where it goes wrong.
It looks like the fireball unit does not trigger the "comes within reach of fireball
dummy".

 

[Druu]

newsflash

locust + projectile unit screwed up my trigger. That was the only problem.

 

[Bond009]

I said pretty much do anything.. lol


I dont think locust ability allows the unit to use spells at all unless its a passive like true sight or something.

Also remove the casting Art animation and blend time on your dummy unit, it will dramatically increase the reaction time for its casting with your trigger.

 

[Dr Super Good]

Locust does, just it can only be orderd to do so via triggers.

Also the Triggering Unit for the unit comes within X of a unit event is the entering unit. Infact there are no natives to return the units who's X range was entered from.

 

[Druu]

I still have a bug here.

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Current order of Fireball_Caster) Equal to (Order("coldarrows"))
  • Then - Actions
    • Set Temp_Loc = (Position of Fireball_Caster)
    • Special Effect - Create a special effect at Temp_Loc using Abilities\Spells\Demon\DarkPortal\DarkPortalTarget.mdl
    • Special Effect - Destroy (Last created special effect)
    • Unit - Create 1 Fireball Unit for (Owner of Fireball_Caster) at Temp_Loc facing Default building facing degrees
    • Unit - Add a 10.00 second Generic expiration timer to (Last created unit)
    • Custom script: call RemoveLocation(udg_Temp_Loc)
    • Set Temp_Loc = (Position of Fireball_Loc)
    • Unit - Order (Last created unit) to Move To Temp_Loc
    • Custom script: call RemoveLocation(udg_Temp_Loc)
  • Else - Actions

I don't get it sometimes a little something turns everything wrong. If I remove
the "s in (current order("coldarrows")) and make it (current order(coldarrows))
I get no effect. But when the "s are there, everything work except for the
fact that I can "cancel" the ability and it still will work. That's what I want to
know about. What can I do to make this not triggered when the spell is canceled
or interupted.

Thanks.

 

[Druu]

Anyone would know why? I'd like an answer please

**Bump**

 

[Berb]

Use another event that detects when a spell is canceled or finished.

 

[Dr Super Good]

You need to detect when the unit stops channeling / gets inturupted via another event and then turn the spell off for it.

 

[Druu]

Isn't that impossible because I made it MUI? Can I via another trigger turn
the spell off for one of the caster and the other would still work?
