Legacy GM [SOLVED] always show object on top of other object which has relative depth

[jobjorgos]

Hey

I want obj_boots always be shown on top of obj_peg (the player) in a 2d top-down (fake 3d perspective) game.

obj_boots

Step Event:

depth = (obj_peg.depth + -1);

But this doesnot work so I wanna make sure if anybody can confirm if this piece of code is right?

obj_boots

Step Event:

// Find depth peg
var newDepth=0;
with obj_peg newDepth=min(newDepth,depth);
// Set depth
depth = newDepth-1;

If you have more that one obj_peg.

But your code should work. Make sure you dont set the depth in another place in the code.

Thanks for your reply.

I have just one single obj_peg so

depth = (obj_peg.depth + -1);

should be good, but indeed but for more obj_peg's then

// Find depth peg
var newDepth=0;
with obj_peg newDepth=min(newDepth,depth);
// Set depth
depth = newDepth-1;

would be a great solution.


Now with some tests I discovered the depth value of obj_boots is unchangable!

With debugging I saw the depthvalue doesnot go with 1 down. Even while I made a specify event 'Press U' that does -1 depth every time I press it doesnot change anything to the depth value whatever I do!
Very strange, only thing which changes the depth value is by moving up/down in the room which I also dont understand cuz this should only change the x and y position, not also depth I guess! How is this possible?

Search for "depth =" or "depth"

You change the depth somewhere in the code that you dont know about.

Thanks for the help, I did some research in meanwhile and I'm happy that I discovered this that fixed the problem:

obj_peg

Step Event:

depth = -bbox_bottom

obj_boots

Step Event:

depth = -y;

I still don't know whats the difference between 'depth = -1' and 'depth = -y', but that doesn't matter it works atleast.

I tried 101 things for obj_boots like

object_set_depth(obj_boots, obj_peg.depth-y);

depth = obj_peg.depth-1000

depth = obj_peg.depth-y*1000

depth = obj_peg.depth-y

etc etc but nothing worked untill I did

obj_peg

Step Event:

depth = -bbox_bottom

So this problem is solved now
