Linking multiple objects to one coding name

Question

I am trying to make an rpg style game in Flash AS3. I am trying to get my character to stop when he hits objects such as trees and buildings. Is there a way I can link multiple objects together and make the code say something like 'take object1, object2, and object3 and name it multipleobjects'? I have the code set up so that the character stops at one tree but I'm not positive how/if you can combine objects so that he won't go through multiple at one time. Thank you very very much in advanced! Objects: manmc (my character), treer1_MC (the first tree) treer2_MC (second tree) and so on

Use an array to keep track of multiple objects.

Instead of manipulating the single object, you then use a loop to iterate over all the elements in the array which are the single objects.
