How can I fix this little piece of code?

[minipimp]

```
Public Sub FindNearestTarget()
Dim i As Long, x As Long, y As Long, x2 As Long, y2 As Long, xDif As Long, yDif As Long
Dim bestX As Long, bestY As Long, bestIndex As Long

x2 = GetPlayerX(MyIndex)
y2 = GetPlayerY(MyIndex)

bestX = 255
bestY = 255

For i = 1 To MAX_MAP_NPCS
If MapNpc(i).num > 0 Then
x = MapNpc(i).x
y = MapNpc(i).y
' find the difference - x
If x < x2 Then
xDif = x2 - x
ElseIf x > x2 Then
xDif = x - x2
Else
xDif = 0
End If
' find the difference - y
If y < y2 Then
yDif = y2 - y
ElseIf y > y2 Then
yDif = y - y2
Else
yDif = 0
End If
' best so far?
If (xDif + yDif) < (bestX + bestY) Then
bestX = xDif
bestY = yDif
bestIndex = i
End If
End If
Next

' target the best
If bestIndex > 0 And bestIndex <> myTarget Then playertarget bestIndex, TARGET_TYPE_NPC
End Sub

```
It says the sub or function of PLAYERTARGET BESTINDEX is undefined.  im trying to place this in my engine that is based off of Prospects engine. ( dont hate for using this engine )   How could I convert it to work?    Im placing this so when I push the tab button i can cycle through all the nearest npcs around my character instead of using the point to click method.

Try

```
If bestIndex > 0 And bestIndex <> myTarget Then
call playertarget(bestIndex, TARGET_TYPE_NPC) // I always found it odd how some subs (not all) need to be called :S
End If
```
Looks like playertarget (the sub or function) is missing did you type it exact?if you named the sub, playerTarget then it needs to be playerTarget (case matters)

Either do what Lex said or do this: 

```
If bestIndex > 0 And bestIndex <> myTarget Then call playertarget(bestIndex, TARGET_TYPE_NPC)

```

There is no playerTarget sub for that to run to though.

Okay I got it to work with using that If statement and  myTarget = (bestIndex). I took out the targettype npc. how would i add it in ?

```
' target the best
If bestIndex > 0 And bestIndex <> myTarget Then
myTarget = (bestIndex)
End If

```

There is no sub playertarget? If your ripping from another engine you should also get its dependencies the sub you have there just does checks playertarget will do the action

I looked this rip up from a while back on another post from a year or 2 ago.   I guess I can go find the sub from it ^-^ . Thanks yall
