Person Detection Issue

Alright, I have come upon a huge issue. I have a multiplayer game that works much like a 8 movement path for each person. I DO want the characters to be able to pass through each other so players cannot block other players from objects. But I have discovered that if I allow them to move, the character ends up going 'under' the character or walking on their face...

This can look extremely unprofessional in an online game. Any ideas how I can have characters (made up of different objects forced to stay relative to a specific position on the person) to move 'through' the person?

You would have to compare their Y values to see who should be ordered underneath who

I don't want anyone underneath anyone though. Is there a way to have players 'merge' through each other? Sort of how Runescape does it?

What perspective are you using?

2D, you are looking forward down. So a tree would stand up in front of you.

You can use the Layer object to sort the object's drawing order. Sort them using their y-position, that will make them appear to be correctly in front of/behind each other. Note that this works on their position relative to their hotspots. Be sure to keep the location of your hotspots consistent. If you are using a semi-isometric perspective or something like that, it is easiest to put the hotspot at the feet/root/bottom of whatever player or object you want to have ordered correctly.

Also note that it can be a little slow to reorder all objects all the time, so only do it once in a while or when needed. :)
