Is there any way to get a pointer of my type when I know one if its fields. Consider the following piece of pseudo code:

Type mytype

  field entity%
  .
  .
  .

end type

Global a_type_instance.mytype
.
.
.
for c=1 to CountCollisions(an_entity)
  entity_collided = CollisionEntity(an_entity, c)
  if entity_collided <> 0 then a_type_instance = ReturnAPointer(entity_collided)
next

Function ReturnAPointer.mytype(entity%)
 ???
end function

Note: I want to avoid to iterate the list of mytype

Thanks

No, but you can use the tried and tested object / handle method ...

Firstly, when creating the type instance, store the type handle in the entityname like so ..

n.mytype = new mytype
n\entity = createcube() 
nameentity( handle( n ) )

Then when you find your entity collided, simply get the object like so ..

Test.mytype = object.mytype( entityname( entity_collided) )
Test\Life = Tes\Life - 1 ;etc....

Should work just fine.
