Problem with MCs

Hello every1!!

I’m trying to make a platform, adventure game… but I have a problem (actually I have a lot xD) there any way to know what I’m interacting MC, without knowing her name or position? is because, according to the NPC will have a different reaction.

I have managed to attack and hurt and ends up dying. I tried putting a variable ID to each MC, but i dont know how to read from the MC of the main character … So not much good to me xD

any help is welcome ^ ^

sorry if I have not explained well, English is not my best subject XD

I use Action script 2.0 x3
