Overlay objects in 2D

Shatur

I'm trying to make a 2D PRG, but I've faced the difficulty of overlaying objects on each other. How do I make it so that when the player was above the object, it was under it, but when the player is below the object, then vice versa? I recorded the video to better explain what I mean :) https://drive.google.com/open?id=1RCayW4A4IeAs94_RymNxUVO9s3IMoLS6

Not sure if that actually will mean anything to you but you could adjust the players z-index based on the player objects location along the y-axis.

Sorry, did not understand you very much. Can you please explain?

So the idea is that sprites get drawn in a certain order such that ones drawn in front/on top of others are drawn later. That order of 'depth' should be determined by an index number z(depth axis)-index.

Yes, that's what I need! But how do I dynamically determine that when a player is in front of an object to set the index to 1, and when is the back of the object, then set the index to 0?

It's an int(eger) not a bool(ean value) you can have values other than 0 & 1. Also see the bool z_as_relative listed right before int z_index at the third link in my previous post.

edit: As I said in my initial reply you could determine the index value based on y-axis location of the node. Since the z-index is a integer value you would have to think of your world coordinates as a grid and handle every world-space floating point n-units as a integral grid unit.

Thank you! I solved the problem. I made a z-index change when the player enters the object.
