Syntax
(array) Ar_Filter source:array filter:function/lambda
Example
array_var aWords = ar_List "spray", "limit", "elite", "exuberant", "destruction", "present"
array_var aResult = ar_Filter aWords ({array_var aIter} => sv_Length (*aIter) > 6)
Content of aResult: "exuberant", "destruction", "present"
array_var aResult = ar_Filter aActors (begin function { array_var aIter }
ref rActor = aIter["value"]
if rActor.GetDead == 0
SetFunctionValue 1
endif
end)
; equivalent to ar_Filter aActors ({array_var aIter} => !(*aIter).GetDead)
; filters out all dead actors
Notes
- To see why the * operator is used and why aIter is an array_var, see Dereference/Unbox in NVSE Expressions.
- aIter["key"] will contain the index of aWords. If aWords was a String Map then it would contain the string key.
