Full WinBlitz3D FREE

what I do is get the buddy's text and check for sign such as:

If picked_object <> 0 And picked_object <> terrain Then
     xs#=Float#(WB3D_GetGadgetText$(txtXScale))
     ss=Sgn(xs)
     If xs# <> 0 Then
          If ss>0 Then ScaleEntity picked_object,xs,xs,xs
     Else
      xs#=Float#(Abs(1/xs))
     ScaleEntity picked_object,xs#,xs#,xs#
      End If
End If
