--- Quote from: https://github.com/mickelson/attract/blob/master/Layouts.md#Text ---zorder - Get/set the Text's order in the applicable draw list. Objects with a lower zorder are drawn first, so that when objects overlap, the one with the higher zorder is drawn on top. Default value is 0.

--- End quote ---


--- Code: (Layout) ---local gameInfo = container.add_text("[Year] [Manufacturer]", -1, -1, 1, 1);
setProps(gameInfo, config.gameInfo);

local gameInfoBR = container.add_text("[Year] [Manufacturer]", -1, -1, 1, 1);
setProps(gameInfoBR, config.gameInfo);
gameInfoBR.set_rgb(0, 0, 0);
gameInfoBR.set_pos(config.gameInfo.x+(overscan*0.25), config.gameInfo.y+(overscan*0.25));
gameInfoBR.zorder = -1;

printL("Game Info zorder: " + gameInfo.zorder);
printL("Game Info BR zorder: " + gameInfoBR.zorder);

--- End code ---


--- Code: (Terminal) ---Game Info zorder: 0
Game Info BR zorder: -1

--- End code ---

I have two objects. I would like the second object placed under the first. A negative integer does not change the zorder.? Changing the zorder of the second object to 1 places it under the first. Actually, I have no idea. I get whacky results. Does this make sense?

What version of AM are you using? Because zorder changed after 2.2 (or was it 2.3?). Also consider that zorder doesn't work reliably inside a surface

2.5.1-12

I found the commit you were talking about.


--- Quote from: https://github.com/mickelson/attract/commit/e53655f697e178dfa0bfe3c1bf350e1afa94c349 ---- zorder attribute can be set to any integer value.  The value stays
  at whatever it is set to (previous behaviour was that all objects
  had a unique zorder value, forced in to the range of 0 to number
  of objects-1)

This is odd.

Changing the zorder of the first object to 1 AFTER creation of the second object results in the first object being drawn on top of the second. Success. Still interesting.

I see what you are doing here (isn't this a drop shadow for text?)... I did something similar (but used a clone for the shadow), in my case I have a counter (zordertop) which I keep as a track for the zorder of the topmost object over which I want to put stuff, so I just placed


--- Code: ---text_shadow.zorder = zordertop + 3
text.zorder = zordertop + 4
--- End code ---

But you don't have a fixed reference, and you are placing everything in a container, if this container is a surface results will be pretty unpredictable. Otherwise you could use


--- Code: ---text.zorder = (text_shadow.zorder + 1)
--- End code ---
