Spell problem

[Pitakebab]

So I'm making simple flame strike based Ion Cannon spell. I have removed all effects and buffs from the ability and set damage to 0.

• Events
• Unit - A unit Finishes casting an ability
• Conditions
• (Ability being cast) Equal to Ion Cannon (Neutral Hostile)
• Actions
• Wait 1.00 seconds
• Destructible - Create a Ion Cannon at (Target point of ability being cast) facing (Random angle) with scale 4.00 and variation 0
• Wait 2.00 seconds
• Destructible - Remove (Last created destructible)
• Unit Group - Pick every unit in (Units within 500.00 of (Target point of ability being cast)) and do (Unit - Set life of (Picked unit) to ((Life of (Picked unit)) - 800.00))
• Cinematic - Fade out and back in over 1.00 seconds using texture White Mask and color (100.00%, 100.00%, 100.00%) with 0.00% transparency

So my problem is that Ion Cannon beam (destructible) doesn't appear and units are not damaged... Only thing that happens is that white flash. Anyone have an idea what's wrong?

Yes I have an idea whats wrong. You use a wait and the "target point of ability being cast" is lost at that time. Therefor those actions wont work, and only the cinematic action works.

How to fix? Use variables. Create a 'point' type variable, not an array, name it for example 'castpoint'. Then set the point right in the beginning of your trigger, before the wait.

Set 'castpoint' = target point of ability being cast
wait 1 seconds...
descrutible - create a ion cannon at 'castpoint' facing random angle with scale 4.00 and variation 0
etc.
etc.

Got it?

Bad idea... If a unit cast the spell 1 second before another does, the spell will be casted twice at the second spot.
And you will have a leak because you are keeping the point and the group. :/
Well it depend on it's use. If you are planing only 1 unit or a few to being able to cast it, it would be ok.

That's not problem because it's ultimate spell wich can be casted once in 5 minutes.

 

[MetalWarrior]

Wait a minute... You are using
Unit - Set life of UNIT

This may kill invincible unit as well. (It include neutral building.)

There's a time and place for everything. I wasnt going to confuse him talking about MUI or leaks since his problem was very very basic one.

It works well now but I didn't think about that... Now it destroys e.g. goblin merchants and divine shield paladin too
Anyone have idea how to fix that?

 

[MetalWarrior]

Ha ok. XD sorry then. But I still think that he should use (Unit- Damage target for.... etc) because with (Unit - Set life of UNIT) he may harm things he didn't want to like neutral invulnerable building.
I just want to help XD. In my opinion the trigger would be:


IonCannonPoint = Point type variable

• Events
• Unit - A unit Finishes casting an ability
• Conditions
• (Ability being cast) Equal to Ion Cannon (Neutral Hostile)
• Actions
• Set IonCannonPoint = (target point of ability being cast)
• Wait 1.00 seconds
• Destructible - Create a Ion Cannon at (IonCannonPoint) facing (Random angle) with scale 4.00 and variation 0
• Wait 2.00 seconds
• Destructible - Remove (Last created destructible)
• Unit Group - Pick every unit in (Units within 500.00 of (IonCannonPoint)) and do (Unit - Cause (Casting Unit) to damage (picked unit), dealing 800.00 damage of attack type Chaos and damage type Normal))
• Cinematic - Fade out and back in over 1.00 seconds using texture White Mask and color (100.00%, 100.00%, 100.00%) with 0.00% transparency

 

[Pitakebab]

Yeah that is better. Thanks a lot!

 

[MetalWarrior]

No problem. It'S a pleasure of helping others.

Also...

At the very end, write

Custom Script: call RemoveLocation( udg_IonCannonPoint )

Next

Right above the Unit Group, write

Custom Script: set bj_wantDestroyGroup = true

finally, Casting Unit < Triggering Unit

 

[MetalWarrior]

Yea that's the leakless version but his spell is suppose to work each 5 minute, so it should be ok.

 

[PurplePoot]

Theres never a reason not to remove leaks if you can.

Many a map on battle.net sucks cause of its leaks.
