Hey, do functions reset the type pointer? Say i create a single type object, say a ball for break-out. When i call a function to do something to the type, it says it doesn't exist.

Function Check_Ball()
     If B\x>400 Then B\direction_x=-1
End Function

Now, if i add:

Function Check_Ball()
     For B.Ball=Each Ball
          If B\x>400 Then B\direction_x=-1
     Next
End Function

It works. Is this normal behaviour. Seems strange, as i though types were always Global. The exact error is,

"Variable is not a Type"

When i add the for next loop in to cycle thru the one object, it works.

The Type objects are global but the pointers to them are not (unless you declare them as such).

Global B.Ball = New Ball
Function Check_Ball()
     If B\x>400 Then B\direction_x=-1
End Function
