Clearing hashtable location leak

[Garfield1337]

I just have a small question,is there a way to clean location leaks through hashtables or do i have to set those locations to variables and then clean them.
For example,i save a location with 0 and 1 as arrays and i want to clean that position,what should i write...

• Custom script: call RemoveLocation(udg_here?)

Set them in a variable. If not, the leak won't be gone.
Best way for me is using reals X/Y.
So, you will save the X and Y coordinates of the location. Example:

• Set Point1 = (Target point of ability being cast)
• Hashtable - Save (X of Point1) as Key(x) of (Key(Triggering unit)) in Hashtable
• Hashtable - Save (Y of Point1) as Key(y) of (Key(Triggering unit)) in Hashtable
• Custom script: call RemoveLocation (udg_Point1)

The loading part (example):

• Set Real_X = (Load Key(x) of (Key(Triggering unit)) in Hashtable)
• Set Real_Y = (Load Key(y) of (Key(Triggering unit)) in Hashtable)
• Custom script: call CreateUnit ('hfoo', GetOwningPlayer(GetTriggerUnit()), udg_Real_X, udg_Real_Y, 0)

And that one doesn't leak at all

You can also do that, by converting the stored coordinates into a point:

• Set Point2 = (Real_X, Real_Y)
• Custom script: call RemoveLocation (udg_Point2)

It's from Convert coordinates to point. You will remove the leak, without any doubts of whether it leaks or not.

Shortly,i must set the point in a variable in order to clear leak,thanks.

But would it work if i,for example,save point in hashtable and after Wait function i set point variable to hashtable saved point and clear it.

Don't work with waits. Use a dummy unit with expiration timer instead

I have a another question,related to this. Does a point leak when it's designated using coordinates?

 

[Etzer]

I think a point leaks nomatter what, as long as you set up the variable, and if you don't set the variable, then you have used up RAM for no good.

 

[Garfield1337]

Ok,thanks

But, if you use a Unit Group and instead of using "Set UnitGroup = All units in playable map area" but do "Add Picked unit to UnitGroup" it won't leak.

X and Y do not leak, they are simple real values. Points do leak though.
So this:

local unit u = GetTriggerUnit()
local real x = GetUnitX (u)
local real y = GetUnitY (u)
call CreateUnit (GetOwningPlayer(u), 'hfoo', x, y, 0)
set u = null

doesn't leak, but the next one does leak:

local unit u = GetTriggerUnit()
local location l = GetUnitLoc (u)

But if i use,for example Create unit at [convert coordinates to point] facing blablabla
Does it leak?

 

[Pharaoh_]

Yep, that one leaks.
Convert coordinates to point returns a point.
