How to create an image of a unit?

[tw3ye]

• Broodmother Memory Egg
  • Events
    • Unit - A unit Finishes casting an ability
  • Conditions
    • (Ability being cast) Equal to (==) Memory Egg
  • Actions
    • Set HeroBroodmotherMemoryEggCaster = (Triggering unit)
    • Unit - Create 1 Memory Egg Sack for (Owner of (Triggering unit)) at ((Position of (Triggering unit)) offset by -150.00 towards (Facing of (Triggering unit)) degrees) facing Default building facing (270.0) degrees
    • Set HeroBroodmotherMemoryEggPoint = ((Position of (Triggering unit)) offset by -150.00 towards (Facing of (Triggering unit)) degrees)
    • Unit - Add a 5.00 second Generic expiration timer to (Last created unit)
    • Unit - Create 1 Dummy Unit Memory Egg for (Owner of (Triggering unit)) at (Center of Dummy units <gen>) facing Default building facing (270.0) degrees
    • Set HeroBroodmotherMemoryEggDummy = (Last created unit)
    • Hero - Give (Last created unit) a Memory Egg in slot 1
    • Set HeroBroodmotherMemoryEggItem = (Last created item)
    • Wait 5.00 seconds
    • Hero - Order HeroBroodmotherMemoryEggDummy to use HeroBroodmotherMemoryEggItem on HeroBroodmotherMemoryEggCaster
    • Wait 0.90 seconds
    • Unit - Remove HeroBroodmotherMemoryEggDummy from the game

let me easy it for you
MemoryEggDummy gets MemoryEggItem
its based on Item Ilusion now when the ilusion is created i need to Move it to MemoryEgg position...
And i got memory eeg position alredy just how to get image and move it there?
Cast range on item is 999999 and cooldown nothing etc.
EDIT: how to make that udg_removelocation(that point of eeg i set)its name i know but not shure how it goes

Use "Starts the effect of an ability" as Event (this is standard spell casting Event)

I have attached a test map for you to see what's wrong
You can check it out here: Item Illusion

native RemoveLocation takes location whichLocation returns nothing

Example of use

call RemoveLocation(udg_removelocation)

where udg_removelocation is a global created by GUI called removelocation.

If you're making a local variable, just do this:

• Custom script: set Point = null

Point is your early set up point-type variable
Put that at the end of your trigger, this is to clean leak of local variable
For udg_*Variable*, it is global variable, therefore you can use the call RemoveLocation(udg_*YourPointVariableName*)

You need to remove locations (and other handles that can leak) for locals too. The null part clears the pointer afaik. (Which would also leak if it wouldn't be nulled.)

 

[Dr Super Good]

defskull, you need to destroy the location before losing all pointers to it otherwise it will leak. This is because WC3 has no location garbage collection. The null is to stop a handle index recycling bug where the pointed to counter has an incriment of 1 leak in it unless you null a local handle which means it can never reach 0 (and thus be recycled).

In SC2 you do not even need to null the local and it will automatically destroy the point (SC2's type of location) because it does have garbage collection.

defskull, you need to destroy the location

How do we do that in GUI Custom script ?
Never learned that @.@", teach me

 

[Dr Super Good]

call RemoveLocation(udg_removelocation)

Where udg_removelocation is a global created by GUI called removelocation of type point. (actual jass type is location).
You place this in a Custom Script block, or in a JASS function.

 

[defskull]

Must the cleaning location be done on global variable ?
Can't we use local instead ?
Hate to set variable, lol.

 

[mckill2009]

if you wanna clean locals...

local location point
//actions here
call RemoveLocation(point)
set point = null

 

[Dr Super Good]

Ofcourse you can use a local variable instead... It takes any location value if you read the function definition. You could even do something stupid and pass it a created location like...
call RemoveLocation(Location(0,0))
Which would be entirly pointless, valid and still not leak.

I usually use the wand of illusion for that, though.
But right now I'm not too sure what you meant so I'll try to find out a better way
