Thanks for replies, linepick and entity distance are nice alternatives and I may use them later on. But back to collision functionality.
Is there way to get 'Type' object that was collided?
Lets say I have two Types and I perform collision checks

Type Target
  Field entity
End Type

Type Bullet
  Field entity
End Type

myBullet.Bullet = new Bullet 
myTarget.Target = new Target
...
For t.Target=Each Target
  If CountCollisions( t\entity )
    If EntityCollided( t\entity, TYPE_BULLET )
      For k=1 To CountCollisions( t\entity )
        If GetEntityType( CollisionEntity( t\entity,k ))=TYPE_BULLET
          ; now I can free Target entity and delete Target object if I wish, but..
          bullet = CollisionEntity( t\entity,k )
          ;
          ; WHAT NOW? I have 'bullet' entity that I can free but how to get Bullet type object that holds that entity?
          ;
        EndIf
      Next
    EndIF
  EndIf
Next

I know, my current method works ok but above system could cut half the code load. Am I trying to optimize too much? :)
