Hi,
yes, I was talking about another action and realize it wasn't available as is, so I made one, you can get it on the Ecosystem: GetSqrDistance.
1000 units is going to give you a lot more trouble in terms of individual logic than physics triggers. Physics has been optimize to great extends for this, while if you start to manually check distance and sort ennemies, you may end up with a less efficient solution in the end, proper profiling will be required to optimize your algorythm.
