[Request] Spell - Wildfire

[Trigger] Spell - Need Help

I'd like some help creating this spell in either GUI or JASS, should be MUI.

Spell: Wildfire

Description: Ignites the target in flames dealing 1 damage per second for 10 seconds. After the duration or if the target dies the spell should bounce to a random nearby enemy unit and should start the spell over again. The spell ends immediately if there are no nearby enemy units.

Level 1 - Bounces a maximum of 2 times (ignites 3 targets total)
Level 2 - Bounces a maximum of 3 times (ignites 4 targets total)
Level 3 - Bounces a maximum of 4 times (ignites 5 targets total)

Any help would be appreciated.

• Wild Fire
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to test
  • Actions
    • Wait until (((Triggering unit) has buff Parasite) Equal to False), checking every 1.00 seconds
    • Unit - Create 1 Dummy for (Owner of (Casting unit)) at (Position of (Target unit of ability being cast)) facing (Position of (Target unit of ability being cast))
    • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from (Units within 700.00 of (Position of (Target unit of ability being cast))))

Basically this is what I have so far.. When you cast the spell the wait never happens, I think maybe because it happens before the target is effected by the spell? Also sometimes the dummy unit casts the spell on another target in range and sometimes it doesn't..?

based if of shadow strike, and then run a trigger that checks if the unit has that buff every 1 second, for 10 seconds... and then if the buff goes away, run another trigger that checks a unit within x range of that targeted unit, and then create a dummy to cast widfire on that unit!

I've updated my post with the spell I created.

Updated title of post.

Bump.

Do that?

 

[Ensabahnur]

I tried basing it off of acid bomb but the dummy doesn't cast the spell, so I'm using parasite instead and as my first post indicates - it's not working right.

Alright, here's a few errors with your triggers:

• Trigger
  • Events
  • Conditions
  • Actions
  • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from (Units within 700.00 of (Position of (Target unit of ability being cast))))

This targets a random unit. ANY unit. This means it targets units that are FRIENDLY to the dummy unit as well, as well as buildings, and immune units, as well as dead units (yea). When such a unit is randomly targeted, it will try to cast parasite, but (you guessed it), it can't parasite a friendly unit/building/immune/dead unit. You will have to add checks to it. Not to mention that this leaks. Do this:

• Trigger
  • Events
  • Conditions
  • Actions
  • Set Point = (Position of (Target unit of ability being cast))
  • Set UnitGroup = (Units within 700.00 of (Point) Matching (Unit Belongs to an Enemy of (Owner of (Triggering Unit)) and (Unit Is (A Structure) Equal To False) and (Unit Is (Magic Immune) Equal To False) and (((Triggering unit) is alive) equal to True))
  • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from UnitGroup)
  • Custom script: call RemoveLocation(udg_Point)
  • Custom script: call DestroyGroup(udg_UnitGroup)

Now, your trigger has a "Wait" in it, after which you are using "Target Unit of Ability Being Cast", this could bug. Instead, do this:

• Wild Fire
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to test
  • Actions
    • Custom script: local unit a = GetSpellTargetUnit
    • Wait until (((Triggering unit) has buff Parasite) Equal to True), checking every 0.10 seconds
    • Wait until (((Triggering unit) has buff Parasite) Equal to False), checking every 0.10 seconds
    • Custom script: set udg_TempUnit = a
    • Set Point = (Position of (TempUnit))
    • Unit - Create 1 Dummy for (Owner of (Casting unit)) at Point facing Point)
    • Set UnitGroup = (Units within 700.00 of Point Matching (Unit Belongs to an Enemy of (Owner of (Triggering Unit)) and (Unit Is (A Structure) Equal To False) and (Unit Is (Magic Immune) Equal To False) and (((Triggering unit) is alive) equal to True))
    • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from UnitGroup)))
    • Custom script: call RemoveLocation(udg_Point)
    • Custom script: call DestroyGroup(udg_UnitGroup)
    • Custom script: set a = null

The dummy will stay around as well, so you will have to add an expiration timer to it.

• Wild Fire
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to test
  • Actions
    • Custom script: local unit a = GetSpellTargetUnit
    • Wait until (((Triggering unit) has buff Parasite) Equal to True), checking every 0.10 seconds
    • Wait until (((Triggering unit) has buff Parasite) Equal to False), checking every 0.10 seconds
    • Custom script: set udg_TempUnit = a
    • Set Point = (Position of (TempUnit))
    • Unit - Create 1 Dummy for (Owner of (Casting unit)) at Point facing Point)
    • Set UnitGroup = (Units within 700.00 of Point Matching (Unit Belongs to an Enemy of (Owner of (Triggering Unit)) and (Unit Is (A Structure) Equal To False) and (Unit Is (Magic Immune) Equal To False) and (((Triggering unit) is alive) equal to True))
    • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from UnitGroup)))
    • Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
    • Custom script: call RemoveLocation(udg_Point)
    • Custom script: call DestroyGroup(udg_UnitGroup)
    • Custom script: set a = null

If you still can't get it to work, I'll do it for you, but try first

A much easier way to make this trigger would be to just pick up on the parasite unit's death (since you can't detect the summon), and then pick a random enemy unit in range of the dying unit and cast a new parasite spell.

This way you can rank the bounces by using different unit types without really having to trigger anything. I choose to use a local variable in this example though:

• Ability Wildfire
  • Events
    • Unit - A unit Dies
  • Conditions
    • Or - Any (Conditions) are true
      • Conditions
        • (Unit-type of (Dying unit)) Equal to Wildfire Dummy (1 Bounce)
        • (Unit-type of (Dying unit)) Equal to Wildfire Dummy (2 Bounces)
        • (Unit-type of (Dying unit)) Equal to Wildfire Dummy (3 Bounces)
        • (Unit-type of (Dying unit)) Equal to Wildfire Dummy (4 Bounces)
  • Actions
    • Custom script: local unit u
    • Set temp_location = (Position of (Dying unit))
    • Set temp_group = (Units within 700.00 of temp_location matching ((((Matching unit) belongs to an enemy of (Owner of (Dying unit))) Equal to True) and ((((Matching unit) is alive) Equal to True) and (((Matching unit) has buff Wildfire ) Equal to False))))
    • Unit - Create 1 (Unit-type of (Dying unit)) for (Owner of (Dying unit)) at temp_location facing Default building facing degrees
    • Unit - Order (Last created unit) to Neutral - Parasite (Random unit from temp_group)
    • Custom script: set u = GetLastCreatedUnit()
    • Custom script: call RemoveLocation( udg_temp_location )
    • Wait 2.00 seconds
    • Custom script: call RemoveUnit( u )
    • Custom script: set u = null

Ok this is making more sense now.. I did this ^^ however it doesn't compile I get a Undeclared variable GetSpellTargetUnit error...?

Also did I do this part correct or am I missing another variable?

[Bogrim]

That's because you need to write "GetSpellTargetUnit()". ;-)

 

[madd_999]

the problem with with your very first trigger where:

• Actions
  • Wait until (((Triggering unit) has buff Parasite) Equal to False), checking every 1.00 seconds

and having:

• Events
  • Unit - A unit Starts the effect of an ability

the triggering unit from which he checks the buff is the unit starting the effect.. the caster.. and your description says it is targeted on an enemy unit.. so there is no wait ever.. because the unit doesn't get the buff in the first place..

instead of having triggering unit you should have used:

• Actions
  • Wait until (((Target unit of ability being cast) has buff Parasite) Equal to False), checking every 1.00 seconds

the second problem with your fist trigger would have been to pick a random unit in a 700 range (which includes allies and invulnerable units) but the solution to that problem has already been given..

This won't work, the reason for it is that you are checking if a Dead unit has a buff. Upon death, all of the buffs are removed from the unit before the "A Unit Dies" event is triggered, meaning the third trigger will never happen.

That's because you need to write "GetSpellTargetUnit()". ;-)

This. Terribly sorry, didn't test the trigger before posting it :banghead:, just put () after it and it should work

 

[Ensabahnur]

Thanks for your help. Is this MUI or no? I'm not sure how I would make it MUI..

 

[kingkwong92]

I think it is MUI but I have been wrong.
Hashtables basically make everything MUI (if they are used correctly)
That's my simple rule

 

[Bogrim]

Thanks for your help. Is this MUI or no? I'm not sure how I would make it MUI..

The trigger I posted is MUI and completely function. Try the test map and see. There's really no reason to tinker with hashtables for this spell.

 

[Ensabahnur]

I thought waits make it not MUI?

 

[N(O.O)B]

I thought waits make it not MUI?

This is only true if you store values in global variables before the wait, and use them after the wait. Using (Triggering Unit) after a wait will not change whether the spell is MUI or not, neither will using local variables. The real question is, why did Bogrim use a local variable when you might as well just add an expiration timer to the unit for the same effect? :nuts:

I tried it out and it works great, thanks.

May I ask what you use the local variable "u" for? you set it and wait 2 seconds, then remove it? :O
