Boolean & Boolexpr Difference

[Rui]

Hi.

I've been trying to make a script but it uses the function GroupEnumUnitsInRect, and it takes a booleanexpr or boolexpr or whatever it is named. Problem is, I do not know the difference between those last two.
I've been using "false/true", and obviously it yells at me that it can't turn one into another.

Help is appreciated.
~Thanks for your time. Do not be afraid to answer

boolexpr = handle
boolean = true or false

Ok, so give me an example of how to use the GroupEnumUnitsInRect correctly.

Boolexpr is in this case a filter. For example:

function Explode takes nothing returns nothing
call ExplodeUnitBJ(GetEnumUnit())
endfunction
//
function DeadFilter takes nothing returns boolean
return GetUnitState(GetFilterUnit(), UNIT_STATE_LIFE) <= 0 
endfunction
//
function YourFunction takes nothing returns nothing
local boolexpr filter = Condition(function DeadFilter)
call GroupEnumUnitsInRect(YourGroup, YourRect, filter)
call ForGroup(YourGroup, function Explode)
call DestroyBoolexpr(filter)
endfunction

This will pick every dead unit in YourRect and makes it explode. If you want all units in a rect then just put null at the boolexpr.

it wont compile as I know

local filterfunc filter = Filter(function DeadFilter) :/

(bah Im not sure)

Alright, thanks for the help. I didn't know it was supposed to be a condition. Makes sense, hehe.

 

[Hatred]

You can use both.

Condition:

native Condition        takes code func returns conditionfunc

type conditionfunc      extends     boolexpr

Filter:

native Filter           takes code func returns filterfunc

type filterfunc         extends     boolexpr

LoL right (note to myself: read common.j)
