[JASS] IsUnitEnemy does not work somehow

[m4st4]

hi im working on a simple filter but for some reason the IsUnitEnemy(unit,player) always returns true. I use this simple filter

function DpBoolExp takes nothing returns boolean
    local unit u = GetFilterUnit()
    local player p =GetFilterPlayer()
    
    local boolean b = IsUnitEnemy(u,p)
     
    set p=null
    set u=null

    return b
endfunction

that is called up using

local boolexpr filter=Condition(function DpBoolExp)
call GroupEnumUnitsInRange(gEff,x1,y1,DAM_RANGE(), filter )

and some units in range are enemy units (i checked using player ips) ... the two players atack each other onsight ... so i guess they must be enmies ... and i put the in different forces

any ideas?

There's no IsUnitEnemy function.
Pease try to make only 1 line (that represents what you want to make) in a GUI trigger, then convert it to Custom text, copy its line and parse to your problematic trigger.

IsUnitEnemy is a native!

I don't know what is GetFilterUnit() and GetFilterPlayer(), are those trigger responses for the boolexpr filter of GroupEnumUnits? I had never used the filter before so I wouldn't know.

I think it's the GetFilterPlayer() which is the problem. When you use "GroupEnumUnits..." functions those functions will only transfer the units it will check to the filter and then the filter will return true or false and if it returns true it will add the unit to the group.
Just set the player to a global variable and replace GetFilterPlayer() with that variable.

im pretty certain its the IsUnitEnemy() that does not work, ive printed out the player ids for every unit in the GroupEnumUnits() together with the GetFilterPlayer() ids ... and they are displayed correctly ... but the IsUnitEnemy() always returns true ... or false i forgot ...

anyways the thread is really old 13.06. !!! and im not using filters anymore...havent seen anyone who does... if you know that filters are fast and one should use them plz let me know

@Rui when you use Enum-functions to get a group of units e.g., the function has a booleanexpr as an argument to filter out all units that you dont want to have. as far as i understand ... and ive been known to be wrong ... the booleanexpr is basically a function that returns boolean, in this case that function is called up every time Enum wants to add a unit to the group, and to get that unit or whatever you can use GetFilterUnit() ect. just like you use GetTriggerUnit() with triggers...

sorry if that was too long/short/wrong

GetFilterPlayer IS wrong. That's for player enums.
