Global layers: Objects go missing.

Problem Description

Setting layers to global in the startup layout causes all other objects on all other same-name layers to disappear (editor displays zero objects for the layer in question and runtime will complain about missing instances of objects being referenced). Trying to add new objects to a layout that had objects go missing threw the error message below. Seems to have been a one-off thing, I'm not getting the error message anymore, though layout objects are still missing. Setting the startup layout's layer back to non-global restores the objects in other layouts.

Attach a Capx

https://dl.dropboxusercontent.com/u/705 ... rsBug.capx

Description of Capx

Simple capx with two layouts. Layout 1 has 3 layers and so does Layout 2. Layout 2 also have two objects, one on Layer 1 and one on Layer 2.

Steps to Reproduce Bug

Set layer 1 or layer 2 on first layout to global. Watch layout 2 objects on same-name layer disappear.

Observed Result

Objects disappear/get disabled both in edit-time and in runtime.

Expected Result

That objects don't get disabled

Operating System and Service Pack

Windows 7 Service Pack <at least 1>

Construct 2 Version ID

Updated with capx link

I just checked your link... your layers haven't been assigned global.

Check this capx. it works for me.

It will jump layout1 to layout2 to layout1 etc ever 3 seconds. I added global to both layouts.

layout1 - gui

layout2 gui2

Edit; this is such a cool feature - going to save countless hours - lol

Yeah, but what happens if you try to set one of the local layers to global on Layout 1 with my capx? Do you still see both objects on Layout 2?

Performs as expected.

I changed layer2 to global and added a spritefont saying "I'm Global"

It performs as expected. Am I missing something?

Edit; Your capx only have 1 sprite on layout two. Must I add the other?

okay added other sprite(blue) on and I see both.

[attachment=0:1yo7ss7t][/attachment:1yo7ss7t]

and now added 2nd sprite on startup

[attachment=0:27tnkrvp][/attachment:27tnkrvp]

Works as expected.

Did you add the object - sprite to layout2? because you have to do that else you get error.

[quote:3feowtcm]Edit; You online have 1 sprite on layout two. Must I add the other?

Nope. There are supposed to be two there, one greenish-blue and one purple. The green one is on Layer 1 and the purple on Layer 2.

If you start up the capx and go directly to the Layout 2 tab you should see em both. Then, if you set Layer 1 to global on Layout 1, the green one will vanish from Layout 2. At least that's what happens here.

Okay downloaded your original. Don't know how my changed.

I went layout2, yes both sprites are there.

On layout1, I set layer1 to global and both sprites stayed. Nothing vanished.

Everything worked as expected. Interesting bug, Ashley hates these as they can't be reproduced. Maybe he gets same result as you and can trace it.

I bet! I would too.

I also get this when shutting down C2 right after following the steps in my previous post:

It's by design that if you set a layer to global, it overrides the objects on all the other layers with its own content. However due to the architecture of the editor the overridden layers can't be displayed on the other layouts, so their content will seem to disappear. This is still by design at the moment.

I can reproduce editor issues if you try to modify a globally overridden layer - the editor will prevent that and tell you to modify the original global layer instead. I can reproduce some cases there and I'll try to fix all cases of that for the next beta. However the OP alludes to a runtime error but does not specify how that occurs. Can you describe some more about that? Can you still get it to happen even if you pretend the editor doesn't allow you to modify a layer which has been overridden?

So that means the global setting wipes any objects assigned to same-name layers on other layouts as long as it's in effect? Makes sense that the runtime throws an error then.

If I try to set layers to global on the 'startup' layout in my own project I get this error message during preview:

'Savestate_Lab' is a global object I use to keep track of some variables during the first section of the game. It's meant to minimize savestate size and I destroy it when outside that first section. I also destroy and re-create it each time the game is restarted, including on first-time run. The 'Savestate_Lab' object itself exists on the first layout that gets switched to after the 'startup' layout (on one of the layers that get over-ridden). And the events below happen on the 'startup' layout right before switching.

Me too have the same problem .Thanks for your info.

ErekT - you have not provided a .capx for what you describe, so I cannot investigate it - however if the object only exists on a layer which has been overridden by a global layer, then it acts as if it is not placed anywhere in the project (since the overridden instances on the global layer don't count), so that is by design.

Closing this report as the editor issues should be fixed for the next build.

Yeah, I'd rather not post the entire project file out in the open. Sounds like it's not necessary anymore anyway, but if you still want to double-check with the actual capx, let me know and I'll PM you a link.
