Dynamics Z order sort

I'm thinking how to have a Z order sort to know each object is in front of another, but dynamically/in real time. The idea is to work in a game like Streets of Rage that when the player is in the lower part of the screen he is in front of something that is a bit upper. But to make it works it needs to be in real time, the game must compare the Y position of each element and put them in the correct order. Is it possible?

It is really easy if you think about it , you put all the objects you want in a family and then ;

For each Family ( ordered , from smallest X to biggest X )

-- Family | Move to top

I tried different. I compared the Y, if it's bigger then "Move to front", if it's smaller "move behind". It will be a bit complicated if there are many objects, but it's working well.

Another thing,I'm using the 8 direction behavior. How can I simulate a jump? The behavior has 8 directions and works well, but how can I pressing a button (jump button) can do the player go up on Y and after go back to the original Y? When it does it it can call a jump animation for example.

My bad , I meant Y :P

anyways , to respond to your question , you could try the sine behavior ...

u should try the zsorter plugin, it works very well!
