# Empty an array over time

Hello guys,

I have an Array (buildings) and now I want to select them with a condition XY (_check).

Only if the _check is True, the property should be shared.  It must be taken out of the Buildings array completely.

The script gets a certain number of buildings and over time more and more are taken away until there are none left in the array.

I need a script that goes through an array and whenever a variable is not true, the exact position must be removed from the array.

```Global \$building_1 = [1,2,3,4,"building_1")
Global \$building_2 = [5,6,7,8,"building_2")
Global \$building_3 = [9,10,11,12,"building_3")

Global \$all_Datas[][] = [[\$building_1[0], \$building_1[1], \$building_1[2], \$building_1[3],\$building_1[4]] _
,[\$building_2[0], \$building_2[1], \$building_2[2], \$building_2[3],\$building_2[4]] _
,[\$building_3[0], \$building_3[1], \$building_3[2], \$building_3[3],\$building_3[4]]]

While 1

\$arrayLength = UBound(\$all_Datas, 1) - 1

Local \$shared_array = []

For \$i = 0 To \$arrayLength Step +1

If _check(\$all_Datas[\$i][0], \$all_Datas[\$i][1], \$all_Datas[\$i][2], \$all_Datas[\$i][3]) Then
_ArrayInsert(\$shared_array, \$i, \$all_Datas[\$i][4])
Else
_ArrayDelete (\$all_Datas,\$i)
EndIf

Next

_ArrayDisplay(\$shared_array,"All shared Array.")

_ArrayDisplay(\$all_Datas,"All remaining Buildings")

WEnd```

Thx

I solved it myself:

```_searching()

Func _searching()

\$arrayLength = UBound(\$all_datas) - 1

If \$arrayLength = 0 Then

MsgBox (1,"","Array is completly clear!")
_ArrayDisplay(\$all_datas,"All remaining datas")

Exit

Else

For \$i = 0 To \$arrayLength Step +1

If not _check() Then
_ArrayDelete (\$all_datas,\$i)
_searching()
EndIf

Next

endif

EndFunc

; checker
Func _check()

\$random = Random(1,2,1)

If \$random = 1 Then
Return True
Else
Return False
EndIf

EndFunc```
