ive made a Type called Zombie, and used it to initialize some zombies on the screen:

.places
Data 15,15,80,16,15,57,0,15,70,5,15,80,15,15,70

Restore places
For j = 1 To 5
p.zombie = New zombie
Read k
p\x = k
Read k
p\y = k
Read k
p\z = k
p\t = ENEMY
p\n = LoadAnimMesh("zombie\zombie.b3d")
ScaleEntity p\n,0.1,0.1,0.1
PositionEntity p\n,p\x,p\y,p\z
ExtractAnimSeq p\n,22,36
Animate p\n, 1,0.1,1
EntityRadius p\n,0.1
EntityType p\n,p\t
p\s = IDLE
p\h = 100
Next

then i use the type in a function:

Function CheckGravity()
If Not EntityCollided(p\n,SCENERY)
TranslateEntity p\n,0,-0.1,0
End If
End Function

and i call the function from my main loop like this:

For p.zombie = Each zombie
checkgravity()
checkai()
Next

when i run the program, it gives me the error: "Variable must be a Type", and points to the line:

If Not EntityCollided(p\n,SCENERY)

since that's the first line that calls the type, im assuming that it's the type that has the problem, but really not sure...

p (in the function) is an uninitialized local variable

make it global or pass it in to the function

As you have a few of the same type - best to pass it to the function like so

Function CheckGravity ( p.zombie )
  If Not EntityCollided(p\n,SCENERY) 
    TranslateEntity p\n,0,-0.1,0 
  End If 
End Function

And then call with ...

For p.zombie = Each zombie 
  checkgravity( p ) 
  checkai( p ) 
Next
