Meteor Rain Spell. Help

02-11-2007, 11:11 AM

Hello. I've decided to make Meteor Rain spell. It'll be channeling abillity I was only able to make single meteor but I need many of them.Explanation: I want to make skill that will spawn meteor every 0.5 second in random point in area ( in my case 800 ) that center is casting unit for 5 seconds. Here is what I've made:

Trigger:

Event

Unit - A unit Begins casting ability

Conditions:

(Ability being cast) is equal to Meteor Rain

Actions

Unit - Create 1 Warlock Meteor D for (Owner of (Casting unit)) at (Random point in (Region centered at (Position of (Casting unit)) with size (800.00, 800.00))) facing (Position of (Casting unit))

Unit - Order (Last created unit) to Special - Doom Guard - Rain of Fire (Position of (Triggering unit))

Unit - Add a 2.00 second General expiration timer to (Last created unit)

And my problem is - I don't know how to make next unit after that.

Use a loop

Trigger:

For Each (Integer A) from 1 to 10, do Actions

Loop - Actions

Unit - Create 1 Warlock Meteor D for (Owner of (Casting unit)) at (Random point in (Region centered at (Position of (Casting unit)) with size (800.00, 800.00))) facing (Position of (Casting unit))

Unit - Order (Last created unit) to Special - Doom Guard - Rain of Fire (Position of (Triggering unit))

Unit - Add a 2.00 second General expiration timer to (Last created unit)

If I was you, I would use Special Effects and Unit - Damage Area instead of dummy casters, its a bit overkill for this spell.

PS: If you are reall going to use dummy casters...don't forget to remove them afterwards ;)

The dummy unit has mana? And all whatever? By the way, the unit casts ever at the triggering unit, so..

Don't use Position of (Unit), unless your setting a variable to that, because thats a leak, which will slow your game down every time you use it.
Anyway, if you dont want to you Jass, which i don't think you probally will want to, you need to use a loop and a wait, here is an example:

Trigger:

Meteor Rain

Events

Unit - A unit Starts the effect of an ability

Conditions

(Ability being cast) Equal to Meteor Rain

Actions

Set TempUnit = (Triggering unit)

Set TempPoint = (Position of TempUnit)

For each (Integer A) from 1 to 10, do (Actions)

Loop - Actions

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

If - Conditions

(Current order of TempUnit) Equal to (Order(!YourSpellsChannelOrderString!))

Then - Actions

Set TempPoint2 = (Point(((X of TempPoint) + (Random real number between -400.00 and 400.00)), ((Y of TempPoint) + (Random real number between -400.00 and 400.00))))

Unit - Create 1 Warlock Meteor D for (Owner of TempUnit) at TempPoint2 facing TempPoint

Unit - Order (Last created unit) to Special Doom Guard - Rain Of Fire TempPoint

Unit - Add a 2.00 second Generic expiration timer to (Last created unit)

Wait 0.50 seconds

Custom script: call RemoveLocation(udg_TempPoint2)

Else - Actions

Custom script: call RemoveLocation(udg_TempPoint)

Although, if this is casted twice at the same time in the space of 5 seconds, it will bug.

SzymonK	Trigger: (Current order of TempUnit) Equal to (Order(!YourSpellsChannelOrderString!)) I don't understand what to do in this part :/ so my abillity dont work yet could You explain it to me ? I'm sorry but I'm new at triggered skills.

Pyrogasm	Open your hero ability in the object editor. Then go down to "Text - Order string use/turn on. Insert whatever it says there (case sensitive) in place of "!YourSpellsChannelOrderString!".

TideHunter: Your trigger will prevent the spell from "going with caster" (like Epicenter in DotA), it will stop in a moment when the caster does something else, won't it? Are you sure Szymonik wants this?

Another idea: What about using polar offset? The code will be simplier and it will produce circular area:

Trigger:

Set TempPoint = (Position of (TempUnit) offset by (Random real number between 0.00 and 600.00) towards (Random angle) degrees)

The trigger TheTideHunter made will just hit random spots within a square area.
And Random Angle is actually just a slower version of GetRandomReal(0, 360), or Random Real between 0 and 360.

This is how I would have done it...

Trigger:

Custom Script: set udg_TempPoint = Location( GetLocationX(udg_CastPoint)+GetRandomReal(0, 500)*Cos(GetRandomReal(0, 360)*3.14159/180.0), GetLocationY(udg_CastPoint)+GetRandomReal(0, 500)*Sin(GetRandomReal(0, 360)*3.14159/180.0) )

Like that... I know its big and complicated, but it is just a faster and more leak-free version of

Trigger:

Set TempPoint = (Position of (TempUnit) offset by (Random real number between 0.00 and 500.00) towards (Random angle) degrees)

SzymonK	Thank you all, especially TideHunter. This was very helpful in creation of my map but I warn you I'll be back for more :). zeroXD I could't find your idea working.

It won't be that noticable, only small corners.
