How do I check many objects in a loop?

Hello,

let's say I have 50+ objects, and if 1 of these objects goes below Y 450 I want it to get destroyed. Now..is there a simple way how to check for every object without making 50 conditions?

thank you

/e: i can do it with families..just found it~

just the usual, i think.

if object.Y < 450 then destroy.

this action only occurs for those objects which matched this condition.
