Best strategy to check all elements of a table

[Jose Marin <jose_marin2@...>]

Hi!

I'm testing porting some C++ code to Lua.

One part of the code checks all elements on an array
against each other.

Is there some optimized way of do this in Lua?

I don't have to check collisions twice, only one time
for each pair of objects.

In pseudocode:

for obj1 = list.first to list.end do
   for obj2 = list.first to list.end do
    
      if obj1.collideWith(obj2) then 
        obj1.DoSomething(obj2)
      end
   end
end

Thanks for any tip!
